Product Description

The SST39VF1601C and SST39VF1602C devices are 1M x16 CMOS Multi-Purpose Flash Plus

(MPF+) manufactured with SST proprietary, high performance CMOS SuperFlash technology. The

split-gate cell design and thick-oxide tunneling injector attain better reliability and manufacturability

compared with alternate approaches. The SST39VF160xC writes (Program or Erase) with a 2.7-3.6V

power supply. These devices conform to JEDEC standard pinouts for x16 memories.

Featuring high performance Word-Program, the SST39VF1601C/1602C devices provide a typical

Word-Program time of 7 µsec. These devices use Toggle Bit, Data# Polling, or the RY/BY# pin to indi-

cate the completion of Program operation. To protect against inadvertent write, they have on-chip hard-

ware and Software Data Protection schemes. Designed, manufactured, and tested for a wide spectrum

of applications, these devices are offered with a guaranteed typical endurance of 100,000 cycles. Data

retention is rated at greater than 100 years.

The SST39VF1601C/1602C devices are suited for applications that require convenient and economi-

cal updating of program, configuration, or data memory. For all system applications, they significantly

improve performance and reliability, while lowering power consumption. They inherently use less

energy during Erase and Program than alternative flash technologies. The total energy consumed is a

function of the applied voltage, current, and time of application. Since for any given voltage range, the

SuperFlash technology uses less current to program and has a shorter erase time, the total energy

consumed during any Erase or Program operation is less than alternative flash technologies. These

devices also improve flexibility while lowering the cost for program, data, and configuration storage

applications.

The SuperFlash technology provides fixed Erase and Program times, independent of the number of

Erase/Program cycles that have occurred. Therefore the system software or hardware does not have

to be modified or de-rated as is necessary with alternative flash technologies, whose Erase and Pro-

gram times increase with accumulated Erase/Program cycles.

To meet high density, surface mount requirements, the SST39VF1601C/1602C are offered in 48-lead

TSOP, 48-ball TFBGA, and 48-ball WFBGA packages. See Figures 2, 3, and 4 for pin assignments.

SST39VF1601C / SST39VF1602C

Data Sheet

Microchip Technology Company

Device Operation

Commands are used to initiate the memory operation functions of the device. Commands are written

to the device using standard microprocessor write sequences. A command is written by asserting WE#

low while keeping CE# low. The address bus is latched on the falling edge of WE# or CE#, whichever

occurs last. The data bus is latched on the rising edge of WE# or CE#, whichever occurs first.

The SST39VF1601C/1602C also have the Auto Low Power mode which puts the device in a near

standby mode after data has been accessed with a valid Read operation. This reduces the IDD active

read current from typically 9 mA to typically 3 µA. The Auto Low Power mode reduces the typical IDD

active read current to the range of 2 mA/MHz of Read cycle time. The device exits the Auto Low Power

mode with any address transition or control signal transition used to initiate another Read cycle, with

no access time penalty. Note that the device does not enter Auto-Low Power mode after power-up with

CE# held steadily low, until the first address transition or CE# is driven high.

Read

The Read operation of the SST39VF1601C/1602C is controlled by CE# and OE#, both have to be low

for the system to obtain data from the outputs. CE# is used for device selection. When CE# is high, the

chip is deselected and only standby power is consumed. OE# is the output control and is used to gate

data from the output pins. The data bus is in high impedance state when either CE# or OE# is high.

Refer to the Read cycle timing diagram for further details (Figure 6).

Word-Program Operation

The SST39VF1601C/1602C are programmed on a word-by-word basis. Before programming, the sec-

tor where the word exists must be fully erased. The Program operation is accomplished in three steps.

The first step is the three-byte load sequence for Software Data Protection. The second step is to load

word address and word data. During the Word-Program operation, the addresses are latched on the

falling edge of either CE# or WE#, whichever occurs last. The data is latched on the rising edge of

either CE# or WE#, whichever occurs first. The third step is the internal Program operation which is ini-

tiated after the rising edge of the fourth WE# or CE#, whichever occurs first. The Program operation,

once initiated, will be completed within 10 µs. See Figures 7 and 8 for WE# and CE# controlled Pro-

gram operation timing diagrams and Figure 22 for flowcharts. During the Program operation, the only

valid reads are Data# Polling and Toggle Bit. During the internal Program operation, the host is free to

perform additional tasks. Any commands issued during the internal Program operation are ignored.

During the command sequence, WP# should be statically held high or low.

Sector/Block-Erase Operation

The Sector- (or Block-) Erase operation allows the system to erase the device on a sector-by-sector (or

block-by-block) basis. The SST39VF1601C/1602C offer both Sector-Erase and Block-Erase mode.

The sector architecture is based on a uniform sector size of 2 KWord. The Block-Erase mode is based

on non-uniform block sizes—thirty-one 32 KWord, one 16 KWord, two 4 KWord, and one 8 KWord

blocks. See Figure 5 for top and bottom boot device block addresses. The Sector-Erase operation is

initiated by executing a six-byte command sequence with Sector-Erase command (50H) and sector

address (SA) in the last bus cycle. The Block-Erase operation is initiated by executing a six-byte com-

mand sequence with Block-Erase command (30H) and block address (BA) in the last bus cycle. The

sector or block address is latched on the falling edge of the sixth WE# pulse, while the command (30H

or 50H) is latched on the rising edge of the sixth WE# pulse. The internal Erase operation begins after

the sixth WE# pulse. The End-of-Erase operation can be determined using either Data# Polling or Tog-

gle Bit methods. See Figures 12 and 13 for timing waveforms and Figure 26 for the flowchart. Any

commands issued during the Sector- or Block-Erase operation are ignored. When WP# is low, any

attempt to Sector- (Block-) Erase the protected block will be ignored. During the command sequence,

WP# should be statically held high or low.

Erase-Suspend/Erase-Resume Commands

The Erase-Suspend operation temporarily suspends a Sector- or Block-Erase operation thus allowing

data to be read from any memory location, or program data into any sector/block that is not suspended

for an Erase operation. The operation is executed by issuing one byte command sequence with Erase-

Suspend command (B0H). The device automatically enters read mode typically within 20 µs after the

Erase-Suspend command had been issued. Valid data can be read from any sector or block that is not

suspended from an Erase operation. Reading at address location within erase-suspended sectors/

blocks will output DQ2toggling and DQ6at ‘1’. While in Erase-Suspend mode, a Word-Program opera-

tion is allowed except for the sector or block selected for Erase-Suspend.

To resume Sector-Erase or Block-Erase operation which has been suspended the system must issue

Erase Resume command. The operation is executed by issuing one byte command sequence with

Erase Resume command (30H) at any address in the last Byte sequence.

Chip-Erase Operation

The SST39VF1601C/1602C provide a Chip-Erase operation, which allows the user to erase the entire

memory array to the ‘1’ state. This is useful when the entire device must be quickly erased.

The Chip-Erase operation is initiated by executing a six-byte command sequence with Chip-Erase

command (10H) at address 555H in the last byte sequence. The Erase operation begins with the rising

edge of the sixth WE# or CE#, whichever occurs first. During the Erase operation, the only valid read is

Toggle Bit or Data# Polling. See Table 7 for the command sequence, Figure 11 for timing diagram, and

Figure 26 for the flowchart. Any commands issued during the Chip-Erase operation are ignored. When

WP# is low, any attempt to Chip-Erase will be ignored. During the command sequence, WP# should

be statically held high or low.

Write Operation Status Detection

The SST39VF1601C/1602C provide two software means to detect the completion of a Write (Program

or Erase) cycle, in order to optimize the system write cycle time. The software detection includes two

status bits: Data# Polling (DQ7) and Toggle Bit (DQ6). The End-of-Write detection mode is enabled

after the rising edge of WE#, which initiates the internal Program or Erase operation.

The actual completion of the nonvolatile write is asynchronous with the system; therefore, either a

Data# Polling or Toggle Bit read may be simultaneous with the completion of the write cycle. If this

occurs, the system may possibly get an erroneous result, i.e., valid data may appear to conflict with

either DQ7or DQ6. In order to prevent spurious rejection, if an erroneous result occurs, the software

routine should include a loop to read the accessed location an additional two (2) times. If both reads

are valid, then the device has completed the Write cycle, otherwise the rejection is valid.

SST39VF1601C / SST39VF1602C

Data Sheet

Microchip Technology Company

Ready/Busy# (RY/BY#)

The devices include a Ready/Busy# (RY/BY#) output signal. RY/BY# is an open drain output pin that

indicates whether an Erase or Program operation is in progress. Since RY/BY# is an open drain out-

put, it allows several devices to be tied in parallel to VDD via an external pull-up resistor. After the rising

edge of the final WE# pulse in the command sequence, the RY/BY# status is valid.

When RY/BY# is actively pulled low, it indicates that an Erase or Program operation is in progress.

When RY/BY# is high (Ready), the devices may be read or left in standby mode.

Data# Polling (DQ7)

When the SST39VF1601C/1602C are in the internal Program operation, any attempt to read DQ7will

produce the complement of the true data. Once the Program operation is completed, DQ7will produce

true data. Note that even though DQ7may have valid data immediately following the completion of an internal

Write operation, the remaining data outputs may still be invalid: valid data on the entire data bus will appear in

subsequent successive Read cycles after an interval of 1 µs. During internal Erase operation, any attempt

to read DQ7will produce a ‘0’. Once the internal Erase operation is completed, DQ7will produce a ‘1’.

The Data# Polling is valid after the rising edge of fourth WE# (or CE#) pulse for Program operation. For

Sector-, Block- or Chip-Erase, the Data# Polling is valid after the rising edge of sixth WE# (or CE#)

pulse. See Figure 9 for Data# Polling timing diagram and Figure 23 for a flowchart.

Toggle Bits (DQ6 and DQ2)

During the internal Program or Erase operation, any consecutive attempts to read DQ6will produce

alternating ‘1’s and ‘0’s, i.e., toggling between 1 and 0. When the internal Program or Erase operation

is completed, the DQ6bit will stop toggling. The device is then ready for the next operation. For Sector-

, Block-, or Chip-Erase, the toggle bit (DQ6) is valid after the rising edge of sixth WE# (or CE#) pulse.

DQ6will be set to ‘1’ if a Read operation is attempted on an Erase-Suspended Sector/Block. If Pro-

gram operation is initiated in a sector/block not selected in Erase-Suspend mode, DQ6will toggle.

An additional Toggle Bit is available on DQ2, which can be used in conjunction with DQ6to check

whether a particular sector is being actively erased or erase-suspended. Table 3 shows detailed status

bits information. The Toggle Bit (DQ2) is valid after the rising edge of the last WE# (or CE#) pulse of

Write operation. See Figure 10 for Toggle Bit timing diagram and Figure 23 for a flowchart.

Note: DQ7and DQ2require a valid address when reading status information.

Data Protection

The SST39VF1601C/1602C provide both hardware and software features to protect nonvolatile data

from inadvertent writes.

Hardware Data Protection

Noise/Glitch Protection: A WE# or CE# pulse of less than 5 ns will not initiate a write cycle.

VDD Power Up/Down Detection: The Write operation is inhibited when VDD is less than 1.5V.

Write Inhibit Mode: Forcing OE# low, CE# high, or WE# high will inhibit the Write operation. This pre-

vents inadvertent writes during power-up or power-down.

Hardware Block Protection

The SST39VF1602C supports top hardware block protection, which protects the top 8 KWord block of

the device. The SST39VF1601C supports bottom hardware block protection, which protects the bot-

tom 8KWord block of the device. The Boot Block address ranges are described in Table 4. Program

and Erase operations are prevented on the 8 KWord when WP# is low. If WP# is left floating, it is inter-

nally held high via a pull-up resistor, and the Boot Block is unprotected, enabling Program and Erase

operations on that block.

Hardware Reset (RST#)

The RST# pin provides a hardware method of resetting the device to read array data. When the RST#

pin is held low for at least TRP, any in-progress operation will terminate and return to Read mode. When

no internal Program/Erase operation is in progress, a minimum period of TRHR is required after RST#

is driven high before a valid Read can take place (see Figure 18).

The Erase or Program operation that has been interrupted needs to be re-initiated after the device

resumes normal operation mode to ensure data integrity.

Software Data Protection (SDP)

The SST39VF1601C/1602C provide the JEDEC approved Software Data Protection scheme for all

data alteration operations, i.e., Program and Erase. Any Program operation requires the inclusion of

the three-byte sequence. The three-byte load sequence is used to initiate the Program operation, pro-

viding optimal protection from inadvertent Write operations, e.g., during the system power-up or

power-down. Any Erase operation requires the inclusion of six-byte sequence. These devices are

shipped with the Software Data Protection permanently enabled. See Table 7 for the specific software

command codes. During SDP command sequence, invalid commands will abort the device to read

mode within TRC. The contents of DQ15-DQ8can be VIL or VIH, but no other value, during any SDP

command sequence.

Common Flash Memory Interface (CFI)

The SST39VF1601C/1602C also contain the CFI information to describe the characteristics of the

device. In order to enter the CFI Query mode, the system writes a three-byte sequence, same as prod-

uct ID entry command with 98H (CFI Query command) to address 555H in the last byte sequence.

Additionally, the system can use the one-byte sequence with 55H on the Address and 89H on the Data

Bus to enter the CFI Query mode. Once the device enters the CFI Query mode, the system can read

CFI data at the addresses given in Tables 8 through 10. The system must write the CFI Exit command

to return to Read mode from the CFI Query mode.

Product Identification

The Product Identification mode identifies the devices as the SST39VF1601C, SST39VF1602C, and

manufacturer as SST. This mode may be accessed software operations. Users may use the Software

Product Identification operation to identify the part (i.e., using the device ID) when using multiple man-

ufacturers in the same socket. For details, see Table 7 for software operation, Figure 14 for the Soft-

ware ID Entry and Read timing diagram and Figure 24 for the Software ID Entry command sequence

flowchart.

Product Identification Mode Exit/CFI Mode Exit

In order to return to the standard Read mode, the Software Product Identification mode must be exited.

Exit is accomplished by issuing the Software ID Exit command sequence, which returns the device to

the Read mode. This command may also be used to reset the device to the Read mode after any inad-

vertent transient condition that apparently causes the device to behave abnormally, e.g., not read cor-

rectly. Please note that the Software ID Exit/CFI Exit command is ignored during an internal Program

or Erase operation. See Table 7 for software command codes, Figure 16 for timing waveform, and Fig-

ure 25 for flowcharts.

Security ID

The SST39VF1601C/1602C devices offer a 136 Word Security ID space. The Secure ID space is

divided into two segments—one factory programmed segment and one user programmed segment.

The first segment is programmed and locked at SST with a random 128-bit number. The user segment,

with a 128 word space, is left un-programmed for the customer to program as desired.

To program the user segment of the Security ID, the user must use the Security ID Word-Program

command. To detect end-of-write for the SEC ID, read the toggle bits. Do not use Data# Polling. Once

this is complete, the Sec ID should be locked using the User Sec ID Program Lock-Out. This disables

any future corruption of this space. Note that regardless of whether or not the Sec ID is locked, neither

Sec ID segment can be erased.

The Secure ID space can be queried by executing a three-byte command sequence with Enter Sec ID

command (88H) at address 555H in the last byte sequence. To exit this mode, the Exit Sec ID com-

mand should be executed. Refer to Table 7 for more details.

Power Up Specifications

All functionalities and DC specifications are specified for a VDD ramp rate of greater than 1V per 100

ms (0V to 3V in less than 300 ms). If the VDD ramp rate is slower than 1V per 100 ms, a hardware

reset is required. The recommended VDD power-up to RESET# high time should be greater than 100

µs to ensure a proper reset.
