Data Sheet (Pre limin ar y) General Description The S29GL-S mid density family of devices are 3.0-volt single-power flash memory manufactured using 65 nm MirrorBit technology. The S29GL064S is a 64-Mb device organized as 4,194,304 words or 8,388,608 bytes. Depending on the model number, the devices have 16-bit wide data bus only, or a 16-bit wide data bus that can also function as an 8-bit wide data bus by using the BYTE# input. The devices can be programmed either in the host system or in standard EPROM programmers. Access times as fast as 70 ns are available. Note that each access time has a specific operating voltage range (VCC) as specified in the Product Selector Guide and Ordering Information - S29GL064S. Package offerings include 48-pin TSOP, 56-pin TSOP, 48-ball fine-pitch BGA, and 64-ball Fortified BGA, depending on model number. Each device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. Each device requires only a single 3.0-volt power supply for both read and write functions. In addition to a VCC input, a high-voltage accelerated program (ACC) feature is supported through increased voltage on the WP#/ACC or ACC input. This feature is intended to facilitate system production. The device is entirely command set compatible with the JEDEC single-power-supply flash standard. Commands are written to the device using standard microprocessor write timing. Write cycles also internally latch addresses and data needed for the programming and erase operations. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. The Advanced Sector Protection features several levels of sector protection, which can disable both the program and erase operations in certain sectors. Persistent Sector Protection is a method that replaces the previous 12-volt controlled protection method. Password Sector Protection is a highly sophisticated protection method that requires a password before changes to certain sectors are permitted. Device programming and erasure are initiated through command sequences. Once a program or erase operation begins, the host system need only poll the DQ7 (Data# Polling) or DQ6 (toggle) status bits or monitor the Ready/Busy# (RY/BY#) output to determine whether the operation is complete. To facilitate programming, an Unlock Bypass mode reduces command sequence overhead by requiring only two write cycles to program data instead of four. Hardware data protection measures include a low VCC detector that automatically inhibits write operations during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of sectors of memory. This can be achieved in-system or via programming equipment. The Erase Suspend / Erase Resume feature allows the host system to pause an erase operation in a given sector to read or program any other sector and then complete the erase operation. The Program Suspend / Program Resume feature enables the host system to pause a program operation in a given sector to read any other sector and then complete the program operation. The hardware RESET# pin terminates any operation in progress and resets the device, after which it is then ready for a new operation. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the host system to read boot-up firmware from the flash memory device. The device reduces power consumption in the standby mode when it detects specific voltage levels on CE# and RESET#, or when addresses are stable for a specified period of time. The Write Protect (WP#) feature protects the first or last sector by asserting a logic low on the WP#/ACC pin or WP# pin, depending on model number. The protected sector is still protected even during accelerated programming. The Secure Silicon Region provides a 128-word / 256-byte area for code or data that can be permanently protected. Once this sector is protected, no further changes within the sector can occur. Spansion MirrorBit flash technology combines years of flash memory manufacturing experience to produce the highest levels of quality, reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via hot-hole assisted erase. The data is programmed using hot electron injection. 4 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) Table of Contents Distinctive Characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 General Description . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 1.

Shee t (Prelimi nar y) Device Bus Operations This section describes the requirements and use of the device bus operations, which are initiated through the internal command register. The command register itself does not occupy any addressable memory location. The register is a latch used to store the commands, along with the address and data information needed to execute the command. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. Table 7.1 lists the device bus operations, the inputs and control levels they require, and the resulting output. The following subsections describe each of these operations in further detail. Table 7.1 Device Bus Operations DQ8-DQ15 Operation Read CE# OE# WE# RESET# BYTE# (Note 4) L L H H L or H Addresses DQ0- DQ7 BYTE# = VIH X AIN DOUT DOUT DOUT DOUT WP# ACC X Autoselect (HV) L L H H L or H X H AIN (Note 3) Write (Program / Erase) L H L H L or H (Note 1) X AIN (Note 2) (Note 2) DQ8-DQ14 = High-Z, DQ15 = A-1 L H L H L or H (Note 1) VHH AIN (Note 2) (Note 2) VIO 0.3V X X VIO 0.3V L or H X H X High-Z High-Z High-Z H L or H X X X High-Z High-Z High-Z L L or H X X X High-Z High-Z High-Z Accelerated Program Standby BYTE# = VIL L H H H X X X X X Output Disable Reset Legend: L = Logic Low = VIL H = Logic High = VIH VHH = Voltage for ACC Program Acceleration VID = Voltage for Autoselect X = Don't Care AIN = Address In DIN = Data In DOUT = Data Out Notes: 1. If WP# = VIL, the first or last sector remains protected (for uniform sector devices), and the two outer boot sectors are protected (for boot sector devices). If WP# = VIH, the first or last sector, or the two outer boot sectors are protected or unprotected as determined by the method described in Write Protect (WP#). All sectors are unprotected when shipped from the factory (The Secure Silicon Region may be factory protected depending on version ordered.) 2. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 10.1 on page 56). 3. A9 is raised to VID to enable Autoselect reads. 4. VIL = VSS and VIH = VIO. 7.1 Word / Byte Configuration The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the BYTE# pin is set at logic 1, the device is in word configuration, DQ0-DQ15 are active and controlled by CE#, WE# and OE#. If the BYTE# pin is set at logic 0, the device is in byte configuration, and only data I/O pins DQ0-DQ7 are active and controlled by CE#, WE# and OE#. The data I/O pins DQ8-DQ14 are tri-stated, and the DQ15 pin is used as an input for the LSB (A-1) address function. The BYTE# pin must be driven set to a logic 0 or 1 state prior to CE# being driven low. The BYTE# pin should not change logic state while CE# is low. March 11, 2014 S29GL064S_00_02 S29GL064S 19 Data 7.2 Sheet (Pre limin ar y) Requirements for Reading Array Data All memories require access time to output array data. In a read operation, data is read from one memory location at a time. Addresses are presented to the device in random order, and the propagation delay through the device causes the data on its outputs to arrive with the address on its inputs. The device defaults to reading array data after device power-up or hardware reset. To read data from the memory array, the system must first assert a valid address on Amax-A0, while driving OE# and CE# to VIL. WE# must remain at VIH. Data will appear on DQ15-DQ0 after address access time (tACC), which is equal to the delay from stable addresses to valid output data. The OE# signal must be driven to VIL. Data is output on DQ15-DQ0 pins after the access time (tOE) has elapsed from the falling edge of OE#. See Reading Array Data on page 35 for more information. Refer to Table 15.1 on page 87 and Table 15.2 on page 88 for timing specifications and the timing diagram. Refer to Table 13.1 on page 81 and Table 13.2 on page 82 for the active current specification on reading array data. 7.2.1 Page Mode Read The device is capable of fast page mode read and is compatible with the page mode Mask ROM read operation. This mode provides faster read access speed for random locations within a page. The page size of the device is 8 words / 16 bytes. The appropriate page is selected by the higher address bits A(max)-A3. Address bits A2-A0 in word mode (A2-A-1 in byte mode) determine the specific word within a page. This is an asynchronous operation; the microprocessor supplies the specific word location. The random or initial page access is equal to tACC or tCE and subsequent page read accesses (as long as the locations specified by the microprocessor falls within that page) is equivalent to tPACC. When CE# is deasserted and reasserted for a subsequent access, the access time is tACC or tCE. Fast page mode accesses are obtained by keeping the read-page addresses constant and changing the intra-read page addresses. 7.3 Writing Commands / Command Sequences To write a command or command sequence (which includes programming data to the device and erasing sectors of memory), the system must drive WE# and CE# to VIL, and OE# to VIH. The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the Unlock Bypass mode, only two write cycles are required to program a word, instead of four. The Word Program Command Sequence on page 36 contains details on programming data to the device using both standard and Unlock Bypass command sequences. An erase operation can erase one sector, multiple sectors, or the entire device. Tables 7.2 - 7.5 indicate the address space that each sector occupies. Refer to DC Characteristics on page 81 for the active current specification for the write mode. The AC Characteristics section contains timing specification tables and timing diagrams for write operations. 7.3.1 Write Buffer Write Buffer Programming allows the system write to a maximum of 128 words / 256 bytes in one programming operation. This results in faster effective programming time than the standard programming algorithms. 20 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta 7.3.2 Shee t (Prelimi nar y) Accelerated Program Operation The device offers program operations through the ACC function. This is one of two functions provided by the WP#/ACC or ACC pin, depending on model number. This function is primarily intended to support manufacturing programming operations at the factory. If the system asserts VHH on this pin, the device automatically enters the Unlock Bypass mode, protected sectors will remain protected. The system would use a two-cycle program command sequence as required by the Unlock Bypass mode. Removing VHH from the WP#/ACC or ACC pin, depending on model number, returns the device to normal operation. Note that the WP#/ACC or ACC pin must be raised to VHH prior to any accelerated operation and should return to VIL/VIH after the completion of the accelerated operation. It should not be at VHH for operations other than accelerated programming, or device damage may result. WP# contains an internal pull-up; when unconnected, WP# is at VIH. 7.3.3 Autoselect Functions If the system writes the autoselect command sequence, the device enters the autoselect mode. The system can then read autoselect codes from the internal register (which is separate from the memory array) on DQ7-DQ0. Standard read cycle timings (tACC) apply in this mode. Refer to Autoselect Mode on page 24 and Autoselect Command Sequence on page 36 for more information. 7.4 Standby Mode When the system is not reading or writing to the device, it can be placed in to standby mode. In this mode, current consumption is greatly reduced, and the outputs are placed in the high impedance state, independent of the OE# input. The device enters the CMOS standby mode when the CE# and RESET# pins are both held at VIO 0.3V. (Note that this is a more restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but not within VIO 0.3V, the device is in the standby mode, but the standby current is greater. The device requires standard access time (tACC/tCE) for read access when the device is in either of these standby modes, before it is ready to read data. If the device is deselected during erasure or programming, the device draws active current until the operation is completed. Refer to the DC Characteristics on page 81, for the standby current specification. 7.5 Automatic Sleep Mode The automatic sleep mode reduces device interface energy consumption to the sleep level (ICC6) following the completion of a random read access time. The device automatically enables this mode when addresses remain stable for tACC + 30 ns. While in sleep mode, output data is latched and always available to the system. Output of the data depends on the level of the OE# signal but, the automatic sleep mode current is independent of the OE# signal level. Standard address access timings (tACC or tPACC) provide new data when addresses are changed. Refer to the DC Characteristics on page 81 for the automatic sleep mode current specification ICC6. Automatic sleep helps reduce current consumption especially when the host system clock is slowed for power reduction. During slow system clock periods, read and write cycles may extend many times their length versus when the system is operating at high speed. Even though CE# may be Low throughout these extended data transfer cycles, the memory device host interface will go to the Automatic Sleep current at tACC + 30 ns. The device will remain at the Automatic Sleep current for tASSB. Then the device will transition to the standby current level. This keeps the memory at the Automatic Sleep or standby power level for most of the long duration data transfer cycles, rather than consuming full read power all the time that the memory device is selected by the host system. However, the EAC operates independent of the automatic sleep mode of the host interface and will continue to draw current during an active Embedded Algorithm. Only when both the host interface and EAC are in their standby states is the standby level current achieved. March 11, 2014 S29GL064S_00_02 S29GL064S 21 Data 7.6 Sheet (Pre limin ar y) RESET#: Hardware Reset Pin The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for at least a period of tRP, the device immediately terminates any operation in progress, output pins go to High-Z, and all read / write commands are ignored for the duration of the RESET# pulse. Program / Erase operations that were interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data integrity. Current is reduced for the duration of the RESET# pulse. When RESET# is held at VSS 0.3V long enough, the device draws CMOS standby current (ICC5). The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the flash memory, enabling the system to read the boot-up firmware from the flash memory. Refer to the AC Characteristics on page 87 for RESET# parameters and to Figure 14.4 on page 86 for the timing diagram. 7.7 Output Disable Mode When the OE# input is at VIH, output from the device is disabled. The output pins are placed in a high impedance state. 7.8 Memory Map Table 7.2 S29GL064S (Models 01, 02, V1, V2) Sector Addresses Sector Size (kB/ kwords) Sector A21-A15 Sector Size (kB/ kwords) SA0 0000000 64/32 000000h-00FFFFh 000000h-007FFFh ... ... ... ... ...

This mode is primarily intended for programming equipment to automatically match a device to be programmed with its corresponding programming algorithm. However, the autoselect codes can also be accessed in-system through the command register. When using programming equipment, the autoselect mode requires VID on address pin A9. Address pins A6, A3, A2, A1, and A0 must be as shown in Table 7.6 on page 24. In addition, when verifying sector protection, the sector address must appear on the appropriate highest order address bits (see Table 7.2 - 7.5). Table 7.6 shows the remaining address bits that are don't care. When all necessary bits are set as required, the programming equipment may then read the corresponding identifier code on DQ7-DQ0. Note that the A9 pin must not be at VID for operations other than Autoselect, or device damage may result. Autoselect using VID is supported at room temperature only. It must be raised to VID prior to any autoselect operations and should return to VIL/VIH after the completion of the autoselect operation. It should not be at VID for operations other than autoselect, or device damage may result. To access the autoselect codes in-system, the host system can issue the autoselect command via the command register, as shown in Table 9.3 on page 46 and Table 9.5 on page 50. This method does not require VID. Refer to the Autoselect Command Sequence on page 36 for more information. ID-CFI Location 02h displays sector protection status for the sector selected by the sector address (SA) used in the ID-CFI enter command. To read the protection status of more than one sector it is necessary to exit the ID ASO and enter the ID ASO using the new SA. The access time to read location 02h is always tACC and a read of this location requires CE# to go High before the read and return Low to initiate the read (asynchronous read access). Page mode read between location 02h and other ID locations is not supported. Page mode read between ID locations other than 02h is supported. In x8 mode, address A-1 is ignored and the lower 8 bits of data will be returned for both address.

The WP# Hardware Protection feature is always available, independent of the software managed protection method chosen. 7.10.4 Selecting a Sector Protection Mode All parts default to operate in the Persistent Sector Protection mode. The user must then choose if the Persistent or Password Protection method is most desirable. There are two one-time programmable nonvolatile bits that define which sector protection method is used. If the user decides to continue using the Persistent Sector Protection method, they must set the Persistent Sector Protection Mode Locking Bit. This permanently sets the part to operate only using Persistent Sector Protection. If the user decides to use the password method, they must set the Password Mode Locking Bit. This permanently sets the part to operate only using password sector protection. It is important to remember that setting either the Persistent Sector Protection Mode Locking Bit or the Password Mode Locking Bit permanently selects the protection mode. It is not possible to switch between the two methods once a locking bit is set. It is important that one mode is explicitly selected when the device is first programmed, rather than relying on the default mode alone. This is so that it is not possible for a system program or virus to later set the Password Mode Locking Bit, which would cause an unexpected shift from the default Persistent Sector Protection Mode into the Password Protection Mode. The device is shipped with all sectors unprotected. Spansion offers the option of programming and protecting sectors at the factory prior to shipping the device through the ExpressFlashTM Service. Contact your sales representative for details. It is possible to determine whether a sector is protected or unprotected. See Autoselect Command Sequence on page 36 for details. 7.11 Lock Register The Lock Register consists of 3 bits (DQ2, DQ1, and DQ0). These DQ2, DQ1, DQ0 bits of the Lock Register are programmable by the user. Users are not allowed to program both DQ2 and DQ1 bits of the Lock Register to the 00 state. If the user tries to program DQ2 and DQ1 bits of the Lock Register to the 00 state, the device aborts the Lock Register back to the default 11 state. Once either DQ2 and DQ1 bits of the Lock Register are programmed than no further changes are allow on DQ2 and DQ1. The programming time of the Lock Register is same as the typical word programming time (tWHWH1) without utilizing the Write Buffer of the device. During a Lock Register programming sequence execution, the DQ6 Toggle Bit I toggles until the programming of the Lock Register has completed to indicate programming status. All Lock Register bits are readable to allow users to verify Lock Register statuses. The Customer Secure Silicon Region Protection Bit is DQ0, Persistent Protection Mode Lock Bit is DQ1, and Password Protection Mode Lock Bit is DQ2 are accessible by all users. Each of these bits are non-volatile. DQ15-DQ3 are reserved and must be 1's when the user tries to program the DQ2, DQ1, and DQ0 bits of the Lock Register. The user is not required to program DQ2, DQ1 and DQ0 bits of the Lock Register at the same time. This allows users to lock the Secure Silicon Region and then set the device either permanently into March 11, 2014 S29GL064S_00_02 S29GL064S 25 Data Sheet (Pre limin ar y) Password Protection Mode or Persistent Protection Mode and then lock the Secure Silicon Region at separate instances and time frames. Secure Silicon Region Protection allows the user to lock the Secure Silicon Region area. Persistent Protection Mode Lock Bit allows the user to set the device permanently to operate in the Persistent Protection Mode. Password Protection Mode Lock Bit allows the user to set the device permanently to operate in the Password Protection Mode. Table 7.7 Lock Register Bit 7.12 DQ15-6 DQ5 DQ4 DQ3 DQ2 DQ1 DQ0 Persistent Protection Mode Lock Bit Secure Silicon Region Protection Bit 1 0 Name Don't Care Reserved Reserved Reserved Password Protection Mode Lock Bit Default Value 1 1 1 1 1 Persistent Sector Protection The Persistent Sector Protection method replaces the old 12V controlled protection method while at the same time enhancing flexibility by providing three different sector protection states Dynamically Locked The sector is protected and can be changed by a simple command. Persistently Locked A sector is protected and cannot be changed. Unlocked The sector is unprotected and can be changed by a simple command. To achieve these states, three types of "bits" are used: 7.12.1 Dynamic Protection Bit (DYB) A volatile protection bit is assigned for each sector. After power-up or hardware reset, the contents of all DYB bits are in the "unprotected state". Each DYB is individually modifiable through the DYB Set Command and DYB Clear Command. The DYB bits and Persistent Protect Bits (PPB) Lock bit are defaulted to power up in the cleared state or unprotected state - meaning the all PPB bits are changeable. The Protection State for each sector is determined by the logical OR of the PPB and the DYB related to that sector. For the sectors that have the PPB bits cleared, the DYB bits control whether or not the sector is protected or unprotected. By issuing the DYB Set and DYB Clear command sequences, the DYB bits is protected or unprotected, thus placing each sector in the protected or unprotected state. These are the socalled Dynamic Locked or Unlocked states. They are called dynamic states because it is very easy to switch back and forth between the protected and un-protected conditions. This allows software to easily protect sectors against inadvertent changes yet does not prevent the easy removal of protection when changes are needed. The DYB bits maybe set or cleared as often as needed. The PPB bits allow for a more static, and difficult to change, level of protection. The PPB bits retain their state across power cycles because they are NonVolatile. Individual PPB bits are set with a program command but must all be cleared as a group through an erase command. The PPB Lock Bit adds an additional level of protection. Once all PPB bits are programmed to the desired settings, the PPB Lock Bit may be set to the `freeze state'. Setting the PPB Lock Bit to the freeze state disables all program and erase commands to the Non-Volatile PPB bits. In effect, the PPB Lock Bit locks the PPB bits into their current state. The only way to clear the PPB Lock Bit to the `unfreeze state' is to go through a power cycle, or hardware reset. The Software Reset command does not clear the PPB Lock Bit to the unfreeze state. System boot code can determine if any changes to the PPB bits are needed e.g., to allow new system code to be downloaded. If no changes are needed then the boot code can set the PPB Lock Bit to disable any further changes to the PPB bits during system operation. The WP# write protect pin adds a final level of hardware protection. When this pin is low it is not possible to change the contents of the WP# protected sectors. These sectors generally hold system boot code. So, the 26 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) WP# pin can prevent any changes to the boot code that could override the choices made while setting up sector protection during system initialization. It is possible to have sectors that have been persistently locked, and sectors that are left in the dynamic state. The sectors in the dynamic state are all unprotected. If there is a need to protect some of them, a simple DYB Set command sequence is all that is necessary. The DYB Set and DYB Clear commands for the dynamic sectors switch the DYB bits to signify protected and unprotected, respectively. If there is a need to change the status of the persistently locked sectors, a few more steps are required. First, the PPB Lock Bit must be disabled to the unfreeze state by either putting the device through a power-cycle, or hardware reset. The PPB bits can then be changed to reflect the desired settings. Setting the PPB Lock Bit once again to the freeze state locks the PPB bits, and the device operates normally again. To achieve the best protection, execute the PPB Lock Bit Set command early in the boot code, and protect the boot code by holding WP# = VIL. 7.12.2 Persistent Protection Bit (PPB) A single Persistent (non-volatile) Protection Bit is assigned to each sector. If a PPB is programmed to the protected state through the PPB Program command, that sector is protected from program or erase operations and is therefor read-only. If a PPB requires erasure, all of the sector PPB bits must first be erased in parallel through the All PPB Erase command. The All PPB Erase command preprograms all PPB bits prior to PPB erasing. All PPB bits erase in parallel, unlike programming where individual PPB bits are programmable. The PPB bits are limited to the same number of cycles as a flash memory sector. Programming the PPB bit requires the typical word programming time without utilizing the Write Buffer. During a PPB bit programming and all PPB bit erasing sequence executions, the DQ6 Toggle Bit I toggles until the programming of the PPB bit or erasing of all PPB bits has completed to indicate programming and erasing status. Erasing all of the PPB bits at once requires typical sector erase time. During the erasing of all PPB bits, the DQ3 Sector Erase Timer bit outputs a 1 to indicate the erasure of all PPB bits are in progress. Reading the PPB Status bit requires the initial access time of the device. 7.12.3 Persistent Protection Bit Lock (PPB Lock Bit) A global volatile bit. When set to the freeze state, the PPB bits cannot be changed. When cleared to the unfreeze state, the PPB bits are changeable. There is only one PPB Lock Bit per device. The PPB Lock Bit is cleared to the unfreeze state at power-up or hardware reset. Configuring the PPB Lock Bit to the freeze state requires approximately tWC. Reading the PPB Lock Status bit requires the initial access time (tACC) of the device. Table 7.8 Sector Protection Schemes Protection States DYB Bit PPB Bit PPB Lock Bit Unprotect Unprotect Unfreeze Unprotect Unprotect Freeze Unprotect Protect Unfreeze Unprotect Protect Freeze Protect Unprotect Unfreeze Protect Unprotect Freeze Protect Protect Unfreeze Protect Protect Freeze Sector State Unprotected - PPB and DYB are changeable Unprotected - PPB not changeable, DYB is changeable Protected - PPB and DYB are changeable Protected - PPB not changeable, DYB is changeable Protected - PPB and DYB are changeable Protected - PPB not changeable, DYB is changeable Protected - PPB and DYB are changeable Protected - PPB not changeable, DYB is changeable Table 7.8 contains all possible combinations of the DYB bit, PPB bit, and PPB Lock Bit relating to the status of the sector. In summary, if the PPB bit is set, and the PPB Lock Bit is set, the sector is protected and the protection cannot be removed until the next power cycle or hardware reset clears the PPB Lock Bit to unfreeze state. If the PPB bit is cleared, the sector can be dynamically locked or unlocked. The DYB bit then controls whether or not the sector is protected or unprotected. If the user attempts to program or erase a protected sector, the device ignores the command and returns to read mode. A program or erase command to a protected sector enables status polling for tDP before the device returns to read mode without having modified the contents of the protected sector. The programming of the DYB bit, PPB bit, and PPB Lock Bit for March 11, 2014 S29GL064S_00_02 S29GL064S 27 Data Sheet (Pre limin ar y) a given sector can be verified by writing a DYB Status Read, PPB Status Read, and PPB Lock Status Read commands to the device. The Autoselect Sector Protection Verification outputs the OR function of the DYB bit and PPB bit per sector basis. When the OR function of the DYB bit and PPB bit is a 1, the sector is either protected by DYB or PPB or both. When the OR function of the DYB bit and PPB bit is a 0, the sector is unprotected through both the DYB and PPB. 7.13 Password Sector Protection The Password Sector Protection method allows an even higher level of security than the Persistent Sector Protection method. There are two main differences between the Persistent Sector Protection and the Password Sector Protection methods: When the device is first powered on, or comes out of a reset cycle, the PPB Lock Bit is set to the locked state, or the freeze state, rather than cleared to the unlocked state, or the unfreeze state. The only means to clear and unfreeze the PPB Lock Bit is by writing a unique 64-bit Password to the device. The Password Sector Protection method is otherwise identical to the Persistent Sector Protection method. A 64-bit password is the only additional tool utilized in this method. The password is stored in a one-time programmable (OTP) region outside of the flash memory. Once the Password Protection Mode Lock Bit is set, the password is permanently set with no means to read, program, or erase it. The password is used to clear and unfreeze the PPB Lock Bit. The Password Unlock command must be written to the flash, along with a password. The flash device internally compares the given password with the pre-programmed password. If they match, the PPB Lock Bit is cleared to the unfreezed state, and the PPB bits can be altered. If they do not match, the flash device does nothing. There is a built-in tPPB delay for each password check after the valid 64-bit password is entered for the PPB Lock Bit to be cleared to the unfreezed state. This delay is intended to thwart any efforts to run a program that tries all possible combinations in order to crack the password. 7.14 Password and Password Protection Mode Lock Bit In order to select the Password Sector Protection method, the user must first program the password. Spansion recommends that the password be somehow correlated to the unique Electronic Serial Number (ESN) of the particular flash device. Each ESN is different for every flash device; therefore each password should be different for every flash device. While programming in the password region, the customer may perform Password Read operations. Once the desired password is programmed in, the customer must then set the Password Protection Mode Lock Bit. This operation achieves two objectives: 1. It permanently sets the device to operate using the Password Protection Mode. It is not possible to reverse this function. 2. It also disables all further commands to the password region. All program, and read operations are ignored. Both of these objectives are important, and if not carefully considered, may lead to unrecoverable errors. The user must be sure that the Password Sector Protection method is desired when programming the Password Protection Mode Lock Bit. More importantly, the user must be sure that the password is correct when the Password Protection Mode Lock Bit is programmed. Due to the fact that read operations are disabled, there is no means to read what the password is afterwards. If the password is lost after programming the Password Protection Mode Lock Bit, there is no way to clear and unfreeze the PPB Lock Bit. The Password Protection Mode Lock Bit, once programmed, prevents reading the 64-bit password on the DQ bus and further password programming. The Password Protection Mode Lock Bit is not erasable. Once Password Protection Mode Lock Bit is programmed, the Persistent Protection Mode Lock Bit is disabled from programming, guaranteeing that no changes to the protection scheme are allowed. 28 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta 7.14.1 Shee t (Prelimi nar y) 64-Bit Password The 64-bit password is located in its own memory space and is accessible through the use of the Password Program and Password Read commands. The password function works in conjunction with the Password Protection Mode Lock Bit, which when programmed, prevents the Password Read command from reading the contents of the password on the pins of the device. 7.15 Persistent Protection Bit Lock (PPB Lock Bit) A global volatile bit. The PPB Lock Bit is a volatile bit that reflects the state of the Password Protection Mode Lock Bit after power-up reset. If the Password Protection Mode Lock Bit is also programmed after programming the Password, the Password Unlock command must be issued to clear and unfreeze the PPB Lock Bit after a hardware reset (RESET# asserted) or a power-up reset. Successful execution of the Password Unlock command clears and unfreezes the PPB Lock Bit, allowing for sector PPB bits to be modified. Without issuing the Password Unlock command, while asserting RESET#, taking the device through a power-on reset, or issuing the PPB Lock Bit Set command sets the PPB Lock Bit to a the freeze state. If the Password Protection Mode Lock Bit is not programmed, the device defaults to Persistent Protection Mode. In the Persistent Protection Mode, the PPB Lock Bit is cleared to the unfreeze state after power-up or hardware reset. The PPB Lock Bit is set to the freeze state by issuing the PPB Lock Bit Set command. Once set to the freeze state the only means for clearing the PPB Lock Bit to the unfreeze state is by issuing a hardware or power-up reset. The Password Unlock command is ignored in Persistent Protection Mode. Reading the PPB Lock Bit requires the initial access time (tACC) of the device. 7.16 Secure Silicon Region Flash Memory The Secure Silicon Region feature provides a flash memory region that enables permanent part identification through an Electronic Serial Number (ESN). The Secure Silicon Region is 256 bytes in length, and uses a Secure Silicon Region Indicator Bit (DQ7) in Autoselect Mode to indicate whether or not the Secure Silicon Region is locked when shipped from the factory. This bit is permanently set at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures the security of the ESN once the product is shipped to the field. The factory offers the device with the Secure Silicon Region either customer lockable (standard shipping option) or factory locked (contact a sales representative for ordering information). The customer-lockable version is shipped with the Secure Silicon Region unprotected, allowing customers to program the sector after receiving the device. The customer-lockable version also has the Secure Silicon Region Indicator Bit permanently set to a 0. The factory-locked version is always protected when shipped from the factory, and has the Secure Silicon Region Indicator Bit permanently set to a 1. Thus, the Secure Silicon Region Indicator Bit prevents customer-lockable devices from being used to replace devices that are factory locked. The Secure Silicon Region address space in this device is allocated as follows: Secure Silicon Region Address Range 000000h-000007h Customer Lockable Determined by customer 000008h-00007Fh ESN Factory Locked ExpressFlash Factory Locked ESN ESN or determined by customer Unavailable Determined by customer The system accesses the Secure Silicon Region through a command sequence (see Table 9.3 and Table 9.5). After the system has written the Enter Secure Silicon Region command sequence, it may read the Secure Silicon Region by using the addresses normally occupied by the first sector (SA0). This mode of operation continues until the system issues the Exit Secure Silicon Region command sequence, Reset / ASO Exit command, or until power is removed from the device. On power-up, or following a hardware reset, the device reverts to sending commands to sector SA0. March 11, 2014 S29GL064S_00_02 S29GL064S 29 Data 7.16.1 Sheet (Pre limin ar y) Customer Lockable: Secure Silicon Region NOT Programmed or Protected At the Factory Unless otherwise specified, the device is shipped such that the customer may program and protect the 256-byte Secure Silicon Region. The system may program the Secure Silicon Region using the write-buffer method, in addition to the standard programming command sequence. See Command Definitions on page 35. Note that the ACC function and unlock bypass modes are not available when the Secure Silicon Region is enabled. Programming and protecting the Secure Silicon Region must be used with caution since, once protected, there is no procedure available for unprotecting the Secure Silicon Region area and none of the bits in the Secure Silicon Region memory space can be modified in any way. The Secure Silicon Region area can be protected using one of the following procedures: Write the three-cycle Enter Secure Silicon Region command. To verify the protect / unprotect status of the Secure Silicon Region, follow the algorithm. Once the Secure Silicon Region is programmed, locked and verified, the system must write the Exit Secure Silicon Region command sequence or Reset / ASO Exit command to return to reading and writing within the remainder of the array. 7.16.2 Factory Locked: Secure Silicon Region Programmed and Protected At the Factory In devices with an ESN, the Secure Silicon Region is protected when the device is shipped from the factory. The Secure Silicon Region cannot be modified in any way. An ESN Factory Locked device has an 16-byte random ESN at addresses 000000h-000007h. Please contact your sales representative for details on ordering ESN Factory Locked devices. Customers may opt to have their code programmed by the factory through the ExpressFlash service (Express Flash Factory Locked). The devices are then shipped from the factory with the Secure Silicon Region permanently locked. Contact your sales representative for details on using the ExpressFlash service. 7.17 Write Protect (WP#/ACC) The Write Protect function provides a hardware method of protecting the first or last sector for Uniform Sector Model or it protects the first or last two sectors for the Boot Sector Model without using VID. Write Protect is one of two functions provided by the WP#/ACC input. If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the first or last sector independently of whether those sectors were protected or unprotected. Note that if WP#/ACC is at VIL when the device is in the standby mode, the maximum input load current is increased. See the table in DC Characteristics on page 81. If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the protected sectors previously set to be protected or unprotected using the method described in Section 7.10 -7.15. Note that WP#/ACC contains an internal pull-up; when unconnected, WP#/ACC is at VIH. 7.18 Hardware Data Protection The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent writes (refer to Table 9.3 on page 46 and Table 9.5 on page 50 for command definitions). In addition, the following hardware data protection measures prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or from system noise. 30 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta 7.18.1 Shee t (Prelimi nar y) Low VCC Write Inhibit When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC power-up and power-down. The command register and all internal program / erase circuits are disabled, and the device resets to the read mode. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the proper signals to the control pins to prevent unintentional writes when VCC is greater than VLKO. 7.18.2 Write Pulse Glitch Protection Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle. 7.18.3 Logical Inhibit Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle, CE# and WE# must be a logical zero while OE# is a logical one. 7.18.4 Power-Up Write Inhibit If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising edge of WE#. The internal state machine is automatically reset to the read mode on power-up. March 11, 2014 S29GL064S_00_02 S29GL064S 31 Data 8. Sheet (Pre limin ar y) Common Flash Memory Interface (CFI) The Common Flash Interface (CFI) specification outlines device and host system software interrogation handshake, which allows specific vendor-specified software algorithms to be used for entire families of devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and backward-compatible for the specified flash device families. Flash vendors can standardize their existing interfaces for long-term compatibility. This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address 55h, any time the device is ready to read array data. The system can read CFI information at the addresses given in Table 8.1 on page 32 - Table 8.4 on page 34. To terminate reading CFI data, the system must write the reset command (0xF0) or 0xFF. The system can also write the CFI query command when the device is in the autoselect mode. The device enters the CFI query mode, and the system can read CFI data at the addresses given in Table 8.1 on page 32 - Table 8.4 on page 34. The system must write the reset command to return the device to reading array data. For further information, please refer to the CFI Specification and CFI Publication 100.

Shee t (Prelimi nar y) Command Definitions Writing specific address and data commands or sequences into the command register initiates device operations. Table 9.3 on page 46 and Table 9.5 on page 50 define the valid register command sequences. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. A reset command is then required to return the device to reading array data. All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on the rising edge of WE# or CE#, whichever happens first. Refer to AC Characteristics on page 87 for timing diagrams. 9.1 Reading Array Data The device is automatically set to reading array data after device power-up. No commands are required to retrieve data. The device is ready to read array data after completing an Embedded Program or Embedded Erase algorithm. After the device accepts an Erase Suspend command, the device enters the erase-suspend-read mode, after which the system can read data from any non-erase-suspended sector. After completing a programming operation in the Erase Suspend mode, the system may once again read array data with the same exception. See Erase Suspend / Erase Resume Commands on page 43 for more information. The system must issue the reset command to return the device to the read (or erase-suspend-read) mode if DQ5 goes high during an active program or erase operation, or if the device is in the autoselect mode. See Reset Command below for more information. See also Requirements for Reading Array Data on page 20 for more information. The Read-Only Operations-AC Characteristics on page 87 provide the read parameters, and Figure 15.1 on page 89 shows the timing diagram. 9.2 Reset Command Writing the reset command resets the device to the read or erase-suspend-read mode. Address bits are don't cares for this command. The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This resets the device to the read mode. Once erasure begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in a program command sequence before programming begins. This resets the device to the read mode. If the program command sequence is written while the device is in the Erase Suspend mode, writing the reset command returns the device to the erasesuspend-read mode. Once programming begins, however, the device ignores reset commands until the operation is complete. The reset command may be written between the sequence cycles in an autoselect command sequence. Once in the autoselect mode, the reset command must be written to return to the read mode. If the device entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns the device to the erase-suspend-read mode. If DQ5 goes high during a program or erase operation, writing the reset command returns the device to the read mode (or erase-suspend-read mode if the device was in Erase Suspend). Note that if DQ1 goes high during a Write Buffer Programming operation, the system must write the Write-toBuffer-Abort Reset command sequence to reset the device for the next operation. March 11, 2014 S29GL064S_00_02 S29GL064S 35 Data 9.3 Sheet (Pre limin ar y) Autoselect Command Sequence The autoselect command sequence allows the host system to read several identifier codes at specific addresses: Identifier Code A7:A0 (x16) A6:A-1 (x8) Manufacturer ID 00h 00h Device ID, Cycle 1 01h 02h Device ID, Cycle 2 0Eh 1Ch Device ID, Cycle 3 0Fh 1Eh Secure Silicon Region Factory Protect 03h 06h Sector Protect Verify (SA)02h (SA)04h Note: The device ID is read over three cycles. SA = Sector Address. The autoselect command sequence is initiated by first writing on unlock cycle (two cycles). This is followed by a third write cycle that contains the autoselect command. The device then enters the autoselect mode. The system may read at any address any number of times without initiating another autoselect command sequence: The system must write the reset command to return to the read mode (or erase-suspend-read mode if the device was previously in Erase Suspend). 9.4 Status Register ASO The Status Register ASO contains a single word of registered volatile status for Embedded Algorithms. When the Status Register Read command is issued, the current status is captured by the register and the ASO is entered. The Status Register content appears at all word locations in the device address space. However, it is recommended to read the status only at word location 0 for future compatibility. The first read access in the Status Register ASO or a Software Reset / ASO Exit write command exits the ASO and returns to the address space map in use when the Status Register read command was issued. It is not recommended to perform any other command after the Status Register Read command is given and before the Status Register ASO is exited. 9.5 Enter / Exit Secure Silicon Region Command Sequence The Secure Silicon Region provides a secured data area containing an 8-word / 16-byte random Electronic Serial Number (ESN). The system can access the Secure Silicon Region by issuing the three-cycle Enter Secure Silicon Region command sequence. The device continues to access the Secure Silicon Region until the system issues the four-cycle Exit Secure Silicon Region command sequence or Reset / ASO Exit command which returns the device to normal operation. Table 9.3 on page 46 and Table 9.5 on page 50 show the address and data requirements for both command sequences. See also Secure Silicon Region Flash Memory on page 29 for further information. Note that the ACC function and unlock bypass modes are not available when the Secure Silicon Region is enabled. 9.6 Word Program Command Sequence Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two unlock write cycles, followed by the program set-up command. The program address and data are written next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further controls or timings. The device automatically provides internally generated program pulses and verifies the programmed cell margin. Table 9.3 on page 46 and Table 9.5 on page 50 show the address and data requirements for the word program command sequence, respectively. When the Embedded Program algorithm is complete, the device then returns to the read mode and addresses are no longer latched. The system can determine the status of the program operation by using DQ7 or DQ6. Refer to Write Operation Status on page 55 for information on these status bits. Any commands written to the device during the Embedded Program Algorithm are ignored. Note that the Secure Silicon 36 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) Region, autoselect, and CFI functions are unavailable when a program operation is in progress. Note that a hardware reset immediately terminates the program operation. The program command sequence should be reinitiated once the device returns to the read mode, to ensure data integrity. Programming is allowed in any sequence of address locations and across sector boundaries. Programming to the same word address multiple times without intervening erases (incremental bit programming) requires a modified programming method. For such application requirements, please contact your local Spansion representative. Word programming is supported for backward compatibility with existing flash driver software and for occasional writing of individual words. Use of write buffer programming (see below) is strongly recommended for general programming use when more than a few words are to be programmed. Any bit in a word cannot be programmed from 0 back to a 1. Attempting to do so may cause DQ7 and DQ6 status bits to indicate the operation was successful. However, a succeeding read shows that the data is still 0. Only erase operations can convert a 0 to a 1. 9.7 Unlock Bypass Command Sequence This device features an Unlock Bypass mode to facilitate shorter programming and erase commands. Once the device enters the Unlock Bypass mode, only two write cycles are required to program or erase data, instead of the normal four or six cycles, respectively. The unlock bypass command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the unlock bypass command, 20h. The device then enters the unlock bypass mode. This mode dispenses with the initial two unlock cycles required in the standard program sequence and four unlock cycles in the standard erase command sequence, resulting in faster total programming and erase times.Table 9.3 on page 46 and Table 9.5 on page 50 show the requirements for the unlock bypass command sequences. During the unlock bypass mode, only the Read, Program, Write Buffer Programming, Write-to-Buffer-Abort Reset, Unlock Bypass Sector Erase, Unlock Bypass Chip Erase and Unlock Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle address is `don't care' and the data 90h. The second cycle need only contain the data 00h. The sector then returns to the read mode. 9.8 Write Buffer Programming Write Buffer Programming allows the system write to a maximum of 128 words / 256 bytes in one programming operation. This results in faster effective programming time than the standard programming algorithms. The Write Buffer Programming command sequence is initiated by first writing two unlock cycles. This is followed by a third write cycle containing the Write Buffer Load command written at the Sector Address in which programming occurs. The fourth cycle writes the sector address and the number of word locations, minus one, to be programmed. For example, if the system programs six unique address locations, then 05h should be written to the device. This tells the device how many write buffer addresses are loaded with data and therefore when to expect the Program Buffer to Flash command. The number of locations to program cannot exceed the size of the write buffer or the operation aborts. The fifth cycle writes the first address location and data to be programmed. The write-buffer-page is selected by address bits AMAX-A7. All subsequent address / data pairs must fall within the selected-write-buffer-page. The system then writes the remaining address / data pairs into the write buffer. Write buffer locations may be loaded in any order. The write-buffer-page address must be the same for all address / data pairs loaded into the write buffer. (This means Write Buffer Programming cannot be performed across multiple write-buffer pages.) This also means that Write Buffer Programming cannot be performed across multiple sectors. If the system attempts to load programming data outside of the selected write-buffer page, the operation aborts. Note that if a Write Buffer address location is loaded multiple times, the address / data pair counter is decremented for every data load operation. The host system must therefore account for loading a write-buffer location more than once. The counter decrements for each data load operation, not for each unique writebuffer-address location. Note also that if an address location is loaded more than once into the buffer, the final data loaded for that address is programmed. March 11, 2014 S29GL064S_00_02 S29GL064S 37 Data Sheet (Pre limin ar y) Once the specified number of write buffer locations are loaded, the system must then write the Program Buffer to Flash command at the sector address. Any other address and data combination aborts the Write Buffer Programming operation. The device then begins programming. Data polling should be used while monitoring the last address location loaded into the write buffer. DQ7, DQ6, DQ5, and DQ1 should be monitored to determine the device status during Write Buffer Programming. The write-buffer programming operation can be suspended using the standard program suspend / resume commands. Upon successful completion of the Write Buffer Programming operation, the device is ready to execute the next command. The Write Buffer Programming Sequence can be aborted in the following ways: Load a value that is greater than the page buffer size during the Number of Locations to Program step. Write to an address in a sector different than the one specified during the Write-Buffer-Load command. Write an Address / Data pair to a different write-buffer-page than the one selected by the Starting Address during the write buffer data loading stage of the operation. Write data other than the Confirm Command after the specified number of data load cycles. The abort condition is indicated by DQ1 = 1, DQ7 = DATA# (for the last address location loaded), DQ6 = toggle, and DQ5 = 0. A Write-to-Buffer-Abort Reset command sequence must be written to reset the device for the next operation. Note that the Secure Silicon Region, autoselect, and CFI functions are unavailable when a program operation is in progress. This flash device is capable of handling multiple write buffer programming operations on the same write buffer address range without intervening erases. For applications requiring incremental bit programming, a modified programming method is required; please contact your local Spansion representative. Any bit in a write buffer address range cannot be programmed from 0 back to a 1. Attempting to do so may cause the device to set DQ5 = 1, of cause the DQ7 and DQ6 status bits to indicate the operation was successful. However, a succeeding read shows that the data is still 0. Only erase operations can convert a 0 to a 1. 9.9 Accelerated Program The device supports program operations when the system asserts VHH on the WP#/ACC or ACC pin. When WP#/ACC or ACC pin is lowered back to VIH or VIL the device exits the Accelerated Programming mode and returns to normal operation. The WP#/ACC is VHH tolerant but is not designed to accelerate the program functions. If the system asserts VHH on this input, the device automatically enters the Unlock Bypass mode. The system can then use the Write Buffer Load command sequence provided by the Unlock Bypass mode. Note that if a Write-to-Buffer-Abort Reset is required while in Unlock Bypass mode, the full 3-cycle RESET command sequence must be used to reset the device. Note that the WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device damage may result. WP# contains an internal pull-up; when unconnected, WP# is at VIH. Accelerated programming is supported at room temperature only. Figure 9.1 on page 39 illustrates the algorithm for the program operation. Refer to Table 15.4, Erase / Program Operations on page 93 for parameters, and Figure 15.12 on page 94 for timing diagrams. Sectors must be unlocked prior to raising WP#/ACC to VHH. It is recommended that WP#/ACC apply VHH after power-up sequence is completed. In addition, it is recommended that WP#/ACC apply from VHH to VIH/VIL before powering down VCC/VIO. 38 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) Figure 9.1 Write Buffer Programming Operation Write "Write to Buffer" command and Sector Address Part of "Write to Buffer" Command Sequence Write number of addresses to program minus 1(WC) and Sector Address Write first address/data Yes WC = 0 ?

Therefore, DQ7 should be verified. 3. If this flowchart location was reached because DQ5= 1, then the device Failed. If this flowchart location was reached because DQ1= 1, then the Write to Buffer operation was Aborted. In either case, the proper reset command must be written before the device can begin another operation. If DQ1= 1, write the Write-Buffer-Programming-Abort-Reset command. if DQ5= 1, write the Reset command. 4. See Table 9.3 on page 46 and Table 9.5 on page 50 for command sequences required for write buffer programming.

No Yes Increment Address No Last Address? Yes Programming Completed Note: See Table 9.3 on page 46 and Table 9.5 on page 50 for program command sequence. 9.10 Program Suspend / Program Resume Command Sequence The Program Suspend command allows the system to interrupt a programming operation or a Write to Buffer programming operation so that data can be read from any non-suspended sector. When the Program Suspend command is written during a programming process, the device halts the program operation within tPSL (program suspend latency) and updates the status bits. Addresses are not required when writing the Program Suspend command. There are two commands available for program suspend. The legacy combined Erase / Program suspend command (B0h command code) and the separate Program Suspend command (51h command code). There are also two commands for Program resume. The legacy combined Erase / Program resume command (30h command code) and the separate Program Resume command (50h command code). It is recommended to use the separate program suspend and resume commands for programming and use the legacy combined command only for erase suspend and resume. After the programming operation is suspended, the system can read array data from any non-suspended sector. The Program Suspend command may also be issued during a programming operation while an erase is suspended. In this case, data may be read from any addresses not in Erase Suspend or Program Suspend. If a read is needed from the Secure Silicon Region area (One-time Program area), then user must use the proper command sequences to enter and exit this region. Note that the Secure Silicon Region, autoselect, and CFI functions are unavailable when a program operation is in progress. The system may also write the autoselect command sequence when the device is in the Program Suspend mode. The system can read as many autoselect codes as required. When the device exits the autoselect mode, the device reverts to the Program Suspend mode, and is ready for another valid operation. See Autoselect Command Sequence on page 36 for more information. After the Program Resume command is written, the device reverts to programming. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard 40 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) program operation. See Write Operation Status on page 55 for more information. The system must write the Program Resume command (address bits are don't care) to exit the Program Suspend mode and continue the programming operation. Further writes of the Resume command are ignored. Another Program Suspend command can be written after the device resumes programming. Program operations can be interrupted as often as necessary but in order for a program operation to progress to completion there must be some periods of time between resume and the next suspend command greater than or equal to tPRS as listed in Table 16.1 and Table 16.2.

The chip erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to pre-program prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. Table 9.3 on page 46 and Table 9.5 on page 50 show the address and data requirements for the chip erase command sequence. When the Embedded Erase algorithm is complete, the device returns to the read mode and addresses are no longer latched. The system can determine the status of the erase operation by using DQ7, DQ6, or DQ2. Refer to Write Operation Status on page 55 for information on these status bits. The Unlock Bypass feature allows the host system to send program commands to the flash device without first writing unlock cycles within the command sequence. See Section 9.7 for details on the Unlock Bypass function. Any commands written during the chip erase operation are ignored. However, note that a hardware reset immediately terminates the erase operation. If this occurs, the chip erase command sequence should be reinitiated once the device returns to reading array data, to ensure data integrity. Figure 9.4 on page 43 illustrates the algorithm for the erase operation. Refer to Table 15.2 on page 90 for parameters, and Figure 15.13 on page 95 for timing diagrams. 9.12 Sector Erase Command Sequence Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed by the address of the sector to be erased, and the sector erase command. Table 9.3 on page 46 and Table 9.5 on page 50 shows the address and data requirements for the sector erase command sequence. The device does not require the system to pre-program prior to erase. The Embedded Erase algorithm automatically programs and verifies the entire memory for an all zero data pattern prior to electrical erase. The system is not required to provide any controls or timings during these operations. After the command sequence is written, a sector erase time-out of tSEA occurs. During the time-out period, additional sector addresses and sector erase commands may be written. Invalid commands will be ignored during the time-out period. Loading the sector erase buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The time between these additional cycles must be less than 50 s, otherwise erasure may begin. Any sector erase address and command following the exceeded time-out may or may not be accepted. It is recommended that processor interrupts be disabled during this time to ensure all commands are accepted. The interrupts can be re-enabled after the last Sector Erase command is written. Note that the Secure Silicon Region, autoselect, and CFI functions are unavailable when an erase operation is in progress. The system must rewrite the command sequence and any additional addresses and commands. The system can monitor DQ3 to determine if the sector erase timer has timed out (See DQ3: Sector Erase Timer on page 59.). The time-out begins from the rising edge of the final WE# pulse in the command sequence. If the sector is found to have not completed its last erase successfully, the sector is unconditionally erased. If the last erase was successful, the sector is read to determine if the sector is still erased (blank). The erase operation is started immediately after finding any programmed zero. If the sector is already blank (no programmed zero bit found) the remainder of the erase operation is skipped. This can dramatically reduce erase time when sectors being erased do not need the erase operation. When enabled the blank check feature is used within the parameter erase, sector erase, and bulk erase commands. When blank check is disabled an erase command unconditionally starts the erase operation. When the Embedded Erase algorithm is complete, the device returns to reading array data and addresses are no longer latched. The system can determine the status of the erase operation by reading DQ7, DQ6, or DQ2 in the erasing sector. Refer to Write Operation Status on page 55 for information on these status bits. 42 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) Once the sector erase operation begins, only the Erase Suspend command is valid. All other commands are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs, the sector erase command sequence should be reinitiated once the device returns to reading array data, to ensure data integrity. Figure 9.4 on page 43 illustrates the algorithm for the erase operation. Refer to Table 15.2 on page 90 for parameters, and Figure 15.13 on page 95 for timing diagrams. Figure 9.4 Erase Operation START Write Erase Command Sequence (Notes 1, 2) Data Poll to Erasing Bank from System Embedded Erase algorithm in progress No Data = FFh? Yes Erasure Completed Notes: 1. See Table 9.3 and Table 9.5 for program command sequence. 2. See DQ3: Sector Erase Timer on page 59 for information on the sector erase timer. 9.13 Erase Suspend / Erase Resume Commands The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read data from, or program data to, any sector not selected for erasure. This command is valid only during the sector erase operation, including the tESL time-out period during the sector erase command sequence. The Erase Suspend command is ignored if written during the chip erase operation or Embedded Program algorithm. When the Erase Suspend command is written during the sector erase operation, the device requires tESL (erase suspend latency) to suspend the erase operation. However, when the Erase Suspend command is written during the sector erase time-out, the device immediately terminates the time-out period and suspends the erase operation. After the erase operation is suspended, the device enters the erase-suspend-read mode. The system can read data from or program data to any sector not selected for erasure. (The device erase suspends all sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to Write Operation Status on page 55 for information on these status bits. After an erase-suspended program operation is complete, the device returns to the erase-suspend-read mode. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard word program operation. Refer to Write Operation Status on page 55 for more information. March 11, 2014 S29GL064S_00_02 S29GL064S 43 Data Sheet (Pre limin ar y) In the erase-suspend-read mode, the system can also issue the autoselect command sequence. Refer to the Autoselect Mode on page 24 and Autoselect Command Sequence on page 36 sections for details. To resume the sector erase operation, the system must write the Erase Resume command. Further writes of the Resume command are ignored. Another Erase Suspend command can be written after the chip resumes erasing. During an erase operation, this flash device performs multiple internal operations which are invisible to the system. When an erase operation is suspended, any of the internal operations that were not fully completed must be restarted. As such, if this flash device is continually issued suspend / resume commands in rapid succession, erase progress is impeded as a function of the number of suspends. The result is a longer cumulative erase time than without suspends. Note that the additional suspends do not affect device reliability or future performance. In most systems rapid erase / suspend activity occurs only briefly. In such cases, erase performance is not significantly impacted. Erase operations can be interrupted as often as necessary but in order for an erase operation to progress to completion there must be some periods of time between resume and the next suspend command greater than or equal to tERS as listed in Table 16.1 and Table 16.2. 9.14 Evaluate Erase Status The Evaluate Erase Status (EES) command verifies that the last erase operation on the addressed sector was completed successfully. The EES command can be used to detect erase operations failed due to loss of power, reset, or failure during the erase operation. To initiate a EES on a Sector, write 35h to the sector address (SA), while the EAC is in the standby state The ESS command may not be written while the device is actively programming or erasing or suspended. The EES command does not allow for reads to the array during the operation. Reads to the array while this command is executing will return unknown data. Use the Status Register read to confirm if the device is still busy and when complete if the sector is erased or not. Bit 7 of the Status Register will show if the device is performing a ESS (similar to an erase operation). Bit 5 of the Status Register will be cleared to 0 if the sector is erased and set to 1 if not erased. As soon as any bit is found to not be erased, the device will halt the operation and report the results. Once the ESS is completed, the EAC will return to the Standby State. The EES command requires tEES (refer to Table 16.1 on page 99) to complete and update the erase status in SR. The DRB bit (SR[7]) may be read to determine when the EES command is finished. If a sector is found not erased with SR[5]=1, the sector must be erased again to ensure reliable storage of data in the sector. 9.15 Continuity Check The Continuity Check provides a basic test of connectivity from package connectors to each die pad. This feature is an extension of the legacy unlock cycle sequence used at the beginning of several commands. The unlock sequence is two writes with alternating ones and zeros pattern on the lower portion of the address and data lines with the pattern inverted between the first and second write. To perform a continuity check these patterns are extended to cover all address and data lines: Address Bus Data Bus x16 Mode AMAX - A0 D15-D0 x8 Mode AMAX - A-1 D7-D0 A logic comparison circuit looks for the alternating one and zero pattern that is inverted between the two write cycles. When the correct patterns are detected, the status register bit zero is set to 1. The status register clear command will clear the status register bit zero to a 0. 44 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) Table 9.1 x16 Data Bus S29GL064S Phase Access Type Write Set-Up Address A21 to A0 Data Comment 555 XX71 Clear die status Write Status Register Read command to die Write 555 XX70 Read XXX RD Write 2AAA55 FF00 First continuity cycle Write 1555AA 00FF Second continuity cycle Write 555 XX70 Write Status Register Read command to die Read XXX RD Read status from die to confirm status bit zero = 0 Continuity Pattern Verify continuity pattern detected Read status from die to confirm status bit zero = 1 for continuity pattern detected Table 9.2 X8 Data Bus S29GL064S Phase Set-Up Access Type Address A21 to A-1 Data Comment Write AAA 71 Clear die status Write AAA 70 Write Status Register Read command to die Read XXX RD Read status from die to confirm status bit zero = 0 Write 5554AB FF First continuity cycle Write 2AAB54 00 Second continuity cycle Write AAA 70 Write Status Register Read command to die Read XXX RD Read status from die to confirm status bit zero = 1 for continuity pattern detected Continuity Pattern Verify continuity pattern detected The alternating one and zero pattern checks for adjacent wire shorts.

Checking for different status results from each die checks for working die selection logic.

March 11, 2014 S29GL064S_00_02 S29GL064S 53 Data Sheet (Pre limin ar y) 10. Status Monitoring There are three methods for monitoring EA status. Previous generations of the S29GL flash family used the methods called Data Polling and Ready/Busy# (RY/BY#) Signal. These methods are still supported by the S29GL-S family. One additional method is reading the Status Register. 10.1 Status Register The status of program and erase operations is provided by a single 16-bit status register. The Status Register Read command is written followed by one read access of the status register information. The contents of the status register is aliased (overlaid) in all locations of the device address space. The overlay is in effect for one read access, specifically the next read access that follows the Status Register Read command. After the one status register access, the Status Register ASO is exited. The CE# or OE# signal must go High following the status register read access for tCEPH/tOEPH time to return to the address space active at the time the Status Register Read command was issued. The status register contains bits related to the results - success or failure - of the most recently completed Embedded Algorithms (EA): Erase Status (bit 5), Program Status (bit 4), Write Buffer Abort (bit 3), Sector Locked Status (bit 1), RFU (bit 0). and, bits related to the current state of any in process EA: Device Busy (bit 7), Erase Suspended (bit 6), Program Suspended (bit 2), The current state bits indicate whether an EA is in process, suspended, or completed. The upper 8 bits (bits 15:8) are reserved. These have undefined High or Low value that can change from one status read to another. These bits should be treated as don't care and ignored by any software reading status. The Clear Status Register Command will clear to 0 the results related bits of the status register but will not affect the current state bits. Initiation of an embedded operation will first clear the status register bits. 54 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) Table 10.1 Status Register Bit # 15:8 7 6 5 4 3 2 1 0 Bit Description Reserved Device Ready Bit Erase Suspend Status Bit Erase Status Bit Program Status Bit Write Buffer Abort Status Bit Program Suspend Status Bit Sector Lock Status Bit Continuity Check DRB ESSB ESB PSB WBASB PSSB SLSB CC Bit Name Reset Status X 1 0 0 0 0 0 0 0 Busy Status Invalid 0 Invalid Invalid Invalid Invalid Invalid Invalid Invalid 0= Ready Status X 1 0=No Erase in Suspension 1=Erase in Suspension 0=Erase successful 0=Program successful 1=Erase fail 1=Program fail 0=Program not aborted 1=Program aborted during Write to Buffer command 0=No Program in suspension 1=Program in suspension 0=Sector not locked during operation 1=Sector locked error Continuity Check Pattern not detected 1= Continuity Check Pattern detected Notes: 1. Bits 15 thru 8, and 0 are reserved for future use and may display as 0 or 1. These bits should be ignored (masked) when checking status. 2. Bit 7 is 1 when there is no Embedded Algorithm in progress in the device. 3. Bits 6 thru 1 are valid only if Bit 7 is 1. 4. All bits are put in their reset status by cold reset or warm reset. 5. Bits 5, 4, 3, and 1 and 0 are cleared to 0 by the Clear Status Register command or Reset command. 6. Upon issuing the Erase Suspend Command, the user must continue to read status until DRB becomes 1. 7. ESSB is cleared to 0 by the Erase Resume Command. 8. ESB reflects success or failure of the most recent erase operation. 9. PSB reflects success or failure of the most recent program operation. 10. During erase suspend, programming to the suspended sector, will cause program failure and set the Program status bit to 1. 11. Upon issuing the Program Suspend Command, the user must continue to read status until DRB becomes 1. 12. PSSB is cleared to 0 by the Program Resume Command. 13. SLSB indicates that a program or erase operation failed because the sector was locked. 14. SLSB reflects the status of the most recent program or erase operation. 10.2 Write Operation Status The device provides several bits to determine the status of a program or erase operation: DQ2, DQ3, DQ5, DQ6, and DQ7. Table 10.2 on page 60 and the following subsections describe the function of these bits. DQ7 and DQ6 each offer a method for determining whether a program or erase operation is complete or in progress. The device also provides a hardware-based output signal, RY/BY#, to determine whether an Embedded Program or Erase operation is in progress or is completed. 10.3 DQ7: Data# Polling The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase algorithm is in progress or completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the command sequence. During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When programming in x8 mode, the DQ7 polling value will be the DATA# of the last byte entered, regardless if the byte is at an even or odd address. When the Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system must provide the program address to read valid status information on DQ7. If a program address falls within a protected sector, Data# Polling on DQ7 is active for approximately tDP, then the device returns to the read mode. During the Embedded Erase algorithm, Data# Polling produces a 0 on DQ7. When the Embedded Erase algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7. The system must provide an address within any of the sectors selected for erasure to read valid status information on DQ7. March 11, 2014 S29GL064S_00_02 S29GL064S 55 Data Sheet (Pre limin ar y) After an erase command sequence is written, if all sectors selected for erasing are protected, Data# Polling on DQ7 is active for approximately tDP, then the device returns to the read mode. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a protected sector, the status may not be valid. Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously with DQ0-DQ6 while Output Enable (OE#) is asserted low. That is, the device may change from providing status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read the status or valid data. Even if the device completed the program or erase operation and DQ7 has valid data, the data outputs on DQ0-DQ6 may be still invalid. Valid data on DQ0-DQ7 appears on successive read cycles. Table 10.2 on page 60 shows the outputs for Data# Polling on DQ7. Figure 10.1 on page 56 shows the Data# Polling algorithm. Figure 15.14 on page 95 shows the Data# Polling timing diagram. Figure 10.1 Data# Polling Algorithm START Read DQ15-DQ0 Addr = VA DQ7 = Data? Yes No No DQ5 = 1? Yes Read DQ15-DQ0 Addr = VA DQ7 = Data? Yes No FAIL PASS Notes: 1. VA = Valid address for programming. During a sector erase operation, a valid address is any sector address within the sector being erased. During chip erase, a valid address is any non-protected sector address. 2. DQ7 should be rechecked even if DQ5 = 1 because DQ7 may change simultaneously with DQ5. 56 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta 10.4 Shee t (Prelimi nar y) DQ6: Toggle Bit I Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete, or whether the device entered the Erase Suspend mode. Toggle Bit I may be read at any address, and is valid after the rising edge of the final WE# pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out. During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. The system may use either OE# or CE# to control the read cycles. When the operation is complete, DQ6 stops toggling. After an erase command sequence is written, if all sectors selected for erasing are protected, DQ6 toggles for approximately tDP, then returns to reading array data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the selected sectors that are protected. The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erasesuspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use DQ7 (see DQ7: Data# Polling on page 55). If a program address falls within a protected sector, DQ6 toggles for approximately tDP after the program command sequence is written, then returns to reading array data. DQ6 also toggles during the erase-suspend-program mode, and stops toggling once the Embedded Program algorithm is complete. Table 10.2 on page 60 shows the outputs for Toggle Bit I on DQ6. Figure 10.2 on page 58 shows the toggle bit algorithm. Figure 15.15 on page 96 shows the toggle bit timing diagrams. Figure 15.16 on page 96 shows the differences between DQ2 and DQ6 in graphical form. See also DQ2: Toggle Bit II on page 59.

Yes Read DQ7-DQ0 Twice Toggle Bit = Toggle? No Yes Program/Erase Operation Not Complete, Write Reset Command Program/Erase Operation Complete Note: The system should recheck the toggle bit even if DQ5 = 1 because the toggle bit may stop toggling as DQ5 changes to 1. See Reading Toggle Bits DQ6/DQ2 on page 59 for more information. 58 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta 10.5 Shee t (Prelimi nar y) DQ2: Toggle Bit II The "Toggle Bit II" on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. (The Toggle Bit II does not apply to the PPB erase command.) Toggle Bit II is valid after the rising edge of the final WE# pulse in the command sequence. DQ2 toggles when the system reads at addresses within those sectors that were selected for erasure. (The system may use either OE# or CE# to control the read cycles.) But DQ2 cannot distinguish whether the sector is actively erasing or is erase-suspended. DQ6, by comparison, indicates whether the device is actively erasing, or is in Erase Suspend, but cannot distinguish which sectors are selected for erasure. Thus, both status bits are required for sector and mode information. Refer to Table 10.2 on page 60 to compare outputs for DQ2 and DQ6. Figure 10.2 on page 58 shows the toggle bit algorithm in flowchart form. Figure 15.15 on page 96 shows the toggle bit timing diagram. Figure 15.16 on page 96 shows the differences between DQ2 and DQ6 in graphical form. 10.6 Reading Toggle Bits DQ6/DQ2 Refer to Figure 10.2 on page 58 for the following discussion. Whenever the system initially begins reading toggle bit status, it must read DQ7-DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typically, the system would note and store the value of the toggle bit after the first read. After the second read, the system would compare the new value of the toggle bit with the first. If the toggle bit is not toggling, the device completed the program or erase operation. The system can read array data on DQ7-DQ0 on the following read cycle. However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system also should note whether the value of DQ5 is high (see DQ5: Exceeded Timing Limits on page 59). If it is, the system should then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no longer toggling, the device successfully completed the program or erase operation. If it is still toggling, the device did not completed the operation successfully, and the system must write the reset command to return to reading array data. It is recommended that data read for polling only be used for polling purposes. Once toggling has stopped array data will be available on subsequent reads. The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the algorithm when it returns to determine the status of the operation (top of Figure 10.2 on page 58). 10.7 DQ5: Exceeded Timing Limits DQ5 indicates whether the program or erase time exceeded a specified internal pulse count limit. Under these conditions DQ5 produces a 1 indicating that the program or erase cycle was not successfully completed. In all these cases, the system must write the reset command to return the device to the reading the array (or to erase-suspend-read if the device was previously in the erase-suspend-program mode). In this case, it is possible that the flash will continue to communicate busy for up to tTOR after the reset command is sent. 10.8 DQ3: Sector Erase Timer After writing a sector erase command sequence, the system may read DQ3 to determine whether or not erasure began. (The sector erase timer does not apply to the chip erase command or the PPB erase command.) If additional sectors are selected for erasure, the entire time-out also applies after each additional sector erase command. When the time-out period is complete, DQ3 switches from a 0 to a 1. If the time between additional sector erase commands from the system can be assumed to be less than tSEA, the system need not monitor DQ3. See also Sector Erase Command Sequence on page 42. After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6 (Toggle Bit I) to ensure that the device accepted the command sequence, and then read DQ3. If DQ3 is 1, the March 11, 2014 S29GL064S_00_02 S29GL064S 59 Data Sheet (Pre limin ar y) Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored until the erase operation is complete. If DQ3 is 0, the device accepts additional sector erase commands. To ensure the command is accepted, the system software should check the status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last command might not have been accepted. Table 10.2 on page 60 shows the status of DQ3 relative to the other status bits. 10.9 DQ1: Write-to-Buffer Abort DQ1 indicates whether a Write-to-Buffer operation was aborted. Under these conditions DQ1 produces a 1. The system must issue the Write-to-Buffer-Abort-Reset command sequence to return the device to reading array data. See Write Buffer on page 20 for more details. Table 10.2 Write Operation Status Status Embedded Program Algorithm Standard Mode Embedded Erase Algorithm Program Suspend Mode Erase Suspend Mode Write-toBuffer ProgramSuspend Read EraseSuspend Read DQ7 (Note 2) DQ6 DQ5 (Note 1) DQ3 DQ2 (Note 2) DQ7# Toggle 0 N/A 0 Toggle 0 1 Program-Suspended Sector 1 RY/BY# No toggle 0 0 Toggle N/A 0 Invalid (not allowed) 1 Data 1 Non-Program Suspended Sector Erase-Suspended Sector DQ1 No toggle Non-Erase Suspended Sector 0 N/A Toggle N/A Data 1 1 Erase-Suspend-Program (Embedded Program) (Note 5) DQ7# Toggle 0 N/A N/A N/A 0 Busy (Note 3) DQ7# Toggle 0 N/A N/A 0 0 Abort (Note 4) DQ7# Toggle 0 N/A N/A 1 0 Notes: 1. DQ5 switches to 1 when an Embedded Program, Embedded Erase, or Write-to-Buffer operation exceeded the maximum timing limits. Refer to DQ5: Exceeded Timing Limits on page 59 for more information. 2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details. 3. The Data# Polling algorithm should be used to monitor the last loaded write-buffer address location. 4. DQ1 switches to 1 when the device aborts the write-to-buffer operation. 5. DQ6 will not toggle when the sector being polled is a sector selected for sector erase or one of the selected sectors during multi-sector erase. 10.10 RY/BY#: Ready/Busy# The RY/BY# is a dedicated, open-drain output pin which indicates whether an Embedded Algorithm is in progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC. If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.) If the output is high (Ready), the device is in the read mode, the standby mode, or in the erase-suspend-read mode. Table 10.2 on page 60 shows the outputs for RY/BY#. 60 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta Shee t (Prelimi nar y) 10.11 Error Types and Clearing Procedures There are three types of errors reported by the embedded operation status methods. Depending on the error type, the status reported and procedure for clearing the error status is different. Following is the clearing of error status: If an ASO was entered before the error the device remains entered in the ASO awaiting ASO read or a command write. If an erase was suspended before the error the device returns to the erase suspended state awaiting flash array read or a command write. Otherwise, the device will be in standby state awaiting flash array read or a command write. 10.11.1 Embedded Operation Error If an error occurs during an embedded operation (program, erase, evaluate erase status, or password unlock) the device (EAC) remains busy. The RY/BY# output remains Low, data polling status continues to be overlaid on all address locations, and the status register shows ready with valid status bits. The device remains busy until the error status is detected by the host system status monitoring and the error status is cleared. During embedded algorithm error status the Data Polling status will show the following: DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer or last word of the password in the case of the password unlock command. DQ7 = 0 for an erase failure DQ6 continues to toggle DQ5 = 1; Failure of the embedded operation DQ4 is RFU and should be treated as don't care (masked) DQ3 = 1 to indicate embedded sector erase in progress DQ2 continues to toggle, independent of the address used to read status DQ1 = 0; Write buffer abort error DQ0 is RFU and should be treated as don't care (masked) During embedded algorithm error status the Status Register will show the following: SR[7] = 1; Valid status displayed SR[6] = X; May or may not be erase suspended during the EA error SR[5] = 1 on erase; else = 0 SR[4] = 1 on program or password unlock error; else = 0 SR[3] = 0; Write buffer abort SR[2] = 0; Program suspended SR[1] = 0; Protected sector SR[0] = X; RFU, treat as don't care (masked) When the embedded algorithm error status is detected, it is necessary to clear the error status in order to return to normal operation, with RY/BY# High, ready for a new read or command write. The error status can be cleared by writing: Reset command Status Register Clear command Commands that are accepted during embedded algorithm error status are: Status Register Read Reset command Status Register Clear command March 11, 2014 S29GL064S_00_02 S29GL064S 61 Data 10.11.2 Sheet (Pre limin ar y) Protection Error If an embedded algorithm attempts to change data within a protected area (program, or erase of a protected sector or OTP area) the device (EAC) goes busy for a period of 20 to 100 s then returns to normal operation. During the busy period the RY/BY# output remains Low, data polling status continues to be overlaid on all address locations, and the status register shows not ready with invalid status bits (SR[7] = 0). During the protection error status busy period the data polling status will show the following: DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer. DQ7 = 0 for an erase failure DQ6 continues to toggle, independent of the address used to read status DQ5 = 0; to indicate no failure of the embedded operation during the busy period DQ4 is RFU and should be treated as don't care (masked) DQ3 = 1 to indicate embedded sector erase in progress DQ2 continues to toggle, independent of the address used to read status DQ1 = 0; Write buffer abort error DQ0 is RFU and should be treated as don't care (masked) Commands that are accepted during the protection error status busy period are: Status Register Read When the busy period ends the device returns to normal operation, the data polling status is no longer overlaid, RY/BY# is High, and the status register shows ready with valid status bits. The device is ready for flash array read or write of a new command. After the protection error status busy period the Status Register will show the following: SR[7] = 1; Valid status displayed SR[6] = X; May or may not be erase suspended after the protection error busy period SR[5] = 1 on erase error, else = 0 SR[4] = 1 on program error, else = 0 SR[3] = 0; Program not aborted SR[2] = 0; No Program in suspension SR[1] = 1; Error due to attempting to change a protected location SR[0] = X; RFU, treat as don't care (masked) Commands that are accepted after the protection error status busy period are: Any command 62 S29GL064S S29GL064S_00_02 March 11, 2014 Da ta 10.11.3 Shee t (Prelimi nar y) Write Buffer Abort If an error occurs during a Write to Buffer command the device (EAC) remains busy. The RY/BY# output remains Low, data polling status continues to be overlaid on all address locations, and the status register shows ready with valid status bits. The device remains busy until the error status is detected by the host system status monitoring and the error status is cleared. During write to buffer abort (WBA) error status the Data Polling status will show the following: DQ7 is the inversion of the DQ7 bit in the last word loaded into the write buffer DQ6 continues to toggle, independent of the address used to read status DQ5 = 0; to indicate no failure of the programming operation. WBA is an error in the values input by the Write to Buffer command before the programming operation can begin DQ4 is RFU and should be treated as don't care (masked) DQ3 is don't care after program operation as no erase is in progress. If the Write Buffer Program operation was started after an erase operation had been suspended then DQ3 = 1. If there was no erase operation in progress then DQ3 is a don't care and should be masked. DQ2 does not toggle after program operation as no erase is in progress. If the Write Buffer Program operation was started after an erase operation had been suspended then DQ2 will toggle in the sector where the erase operation was suspended and not in any other sector. If there was no erase operation in progress then DQ2 is a don't care and should be masked. DQ1 = 1: Write buffer abort error DQ0 is RFU and should be treated as don't care (masked) During embedded algorithm error status the Status Register will show the following: SR[7] = 1; Valid status displayed SR[6] = X; May or may not be erase suspended during the WBA error status SR[5] = 0; Erase successful SR[4] = 1; Programming related error SR[3] = 1; Write buffer abort SR[2] = 0; No Program in suspension SR[1] = 0; Sector not locked during operation SR[0] = X; RFU, treat as don't care (masked) When the WBA error status is detected, it is necessary to clear the error status in order to return to normal operation, with RY/BY# High, ready for a new read or command write. The error status can be cleared by writing: Write Buffer Abort Reset command - Clears the status register and returns to normal operation Status Register Clear command Commands that are accepted during embedded algorithm error status are: Status Register Read - Reads the status register and returns to WBA busy state Write Buffer Abort Reset command Status Register Clear command March 11, 2014 S29GL064S_00_02 S29GL064S 63 Data Sheet (Pre limin ar y) 11.

Maximum DC input voltage on pin A9 and ACC is +12.5V which may overshoot to +14.0V for periods up to 20 ns. 3. No more than one output may be shorted to ground at a time. Duration of the short circuit should not be greater than one second. 4. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this data sheet is not implied. Exposure of the device to absolute maximum rating conditions for extended periods may affect device reliability. 12.2 Latchup Characteristics This product complies with JEDEC standard JESD78C latchup testing requirements. 12.3 Operating Ranges 12.3.1 Temperature Ranges Industrial (I) Devices Ambient Temperature (TA) -40C to +85C Automotive In-Cabin (V) Devices Ambient Temperature (TA) 12.3.2 -40C to +105C Power Supply Voltages VCC 2.7V to 3.6V VIO 1.65V to VCC + 200 mV Operating ranges define those limits between which the functionality of the device is guaranteed. March 11, 2014 S29GL064S_00_02 S29GL064S 77 Data 12.3.3 Sheet (Pre limin ar y) Power-Up and Power-Down During power-up or power-down VCC must always be greater than or equal to VIO (VCC VIO). The device ignores all inputs until a time delay of tVCS has elapsed after the moment that VCC and VIO both rise above, and stay above, the minimum VCC and VIO thresholds. During tVCS the device is performing power on reset operations. During power-down or voltage drops below VCC Lockout maximum (VLKO), the VCC and VIO voltages must drop below VCC Reset (VRST) minimum for a period of tPD for the part to initialize correctly when VCC and VIO again rise to their operating ranges. See Figure 12.2 on page 79. If during a voltage drop the VCC stays above VLKO maximum the part will stay initialized and will work correctly when VCC is again above VCC minimum. If the part locks up from improper initialization, a hardware reset can be used to initialize the part correctly. Normal precautions must be taken for supply decoupling to stabilize the VCC and VIO power supplies. Each device in a system should have the VCC and VIO power supplies decoupled by a suitable capacitor close to the package connections (this capacitor is generally on the order of 0.1 F). At no time should VIO be greater then 200 mV above VCC (VCC VIO - 200 mV).

Each device in a system should have the VCC and VIO power supplies decoupled by a suitable capacitor close to the package connections (this capacitor is generally on the order of 0.1 F).

Not 100% tested. 2. Timing measured from VCC reaching VCC minimum and VIO reaching VIO minimum to VIH on Reset and VIL on CE#. 3. RESET# Low is optional during POR. If RESET is asserted during POR, the later of tRPH, tVIOS, or tVCS will determine when CE# may go Low. If RESET# remains Low after tVIOS, or tVCS is satisfied, tRPH is measured from the end of tVIOS, or tVCS. RESET must also be High tRH before CE# goes Low. 4. VCC VIO - 200 mV during power-up. 5. VCC and VIO ramp rate can be non-linear. 6. Sum of tRP and tRH must be equal to or greater than tRPH. 14.3.1 Power-On (Cold) Reset (POR) During the rise of power supplies the VIO supply voltage must remain less than or equal to the VCC supply voltage. VIH also must remain less than or equal to the VIO supply. The Cold Reset Embedded Algorithm requires a relatively long, hundreds of s, period (tVCS) to load all of the EAC algorithms and default state from non-volatile memory. During the Cold Reset period all control signals including CE# and RESET# are ignored. If CE# is Low during tVCS the device may draw higher than normal POR current during tVCS but the level of CE# will not affect the Cold Reset EA. CE# or OE# must transition from High to Low or there must be an address transition after tVCS for a valid read operation (tACC or tCE is required after tRH). RESET# may be High or Low during tVCS. If RESET# is Low during tVCS it may remain Low at the end of tVCS to hold the device in the Hardware Reset state. If RESET# is High at the end of tVCS the device will go to the Standby state. When power is first applied, with supply voltage below VRST then rising to reach operating range minimum, internal device configuration and warm reset activities are initiated. CE# is ignored for the duration of the POR operation (tVCS or tVIOS). RESET# Low during this POR period is optional. If RESET# is driven Low during POR it must satisfy the Hardware Reset parameters tRP and tRPH. In which case the Reset operations will be completed at the later of tVCS or tVIOS or tRPH. During Cold Reset the device will draw ICC7 current. Figure 14.3 Power-Up Diagram tVCS VCC tVIOS VIO RESET# tRH tCEH CE# March 11, 2014 S29GL064S_00_02 S29GL064S 85 Data 14.3.2 Sheet (Pre limin ar y) Hardware (Warm) Reset During Hardware Reset (tRPH) the device will draw ICC5 current. When RESET# continues to be held at VSS, the device draws CMOS standby current (ICC4). If RESET# is held at VIL, but not at VSS, the standby current is greater. If a Cold Reset has not been completed by the device when RESET# is asserted Low after tVCS, the Cold Reset# EA will be performed instead of the Warm RESET#, requiring tVCS time to complete. See Figure 14.4, Hardware Reset on page 86. After the device has completed POR and entered the Standby state, any later transition to the Hardware Reset state will initiate the Warm Reset Embedded Algorithm. A Warm Reset is much shorter than a Cold Reset, taking tens of s (tRPH) to complete. During the Warm Reset EA, any in progress Embedded Algorithm is stopped and the EAC is returned to its POR state without reloading EAC algorithms from non-volatile memory. After the Warm Reset EA completes, the interface will remain in the Hardware Reset state if RESET# remains Low. When RESET# returns High the interface will transit to the Standby state. If RESET# is High at the end of the Warm Reset EA, the interface will directly transit to the Standby state. CE# or OE# must transition from High to Low or there must be an address transition after tVCS for a valid read operation (tACC or tCE is required). If POR has not been properly completed by the end of tVCS, a later transition to the Hardware Reset state will cause a transition to the Power-on Reset interface state and initiate the Cold Reset Embedded Algorithm. This ensures the device can complete a Cold Reset even if some aspect of the system Power-On voltage ramp-up causes the POR to not initiate or complete correctly. The RY/BY# pin is Low during cold or warm reset as an indication that the device is busy performing reset operations. Hardware Reset is initiated by the RESET# signal going to VIL.

Erase And Programming Performance The Joint Electron Device Engineering Council (JEDEC) standard JESD22-A117 defines the procedural requirements for performing valid endurance and retention tests based on a qualification specification. This methodology is intended to determine the ability of a flash device to sustain repeated data changes without failure (program / erase endurance) and to retain data for the expected life (data retention). Endurance and retention qualification specifications are specified in JESD47 or may be developed using knowledge-based methods as in JESD94.
