ADVANCE INFORMATION

General Description

The S29JL032H is a 32 megabit, 3.0 volt -only flash memory device, organized as

2,097,152 wor ds of 16 bits each or 4,194, 304 bytes of 8 bits each. Word mod e

data appears on DQ15–DQ0; byte mode data appears on D Q7–DQ 0. Th e dev ice

is designed to be pr ogrammed in-system with the s tandard 3.0 volt VCC supply,

and can also be programmed in standard EPROM programmers.

The device is av ailable with an access time of 55, 60, 70, or 90 ns and is offered

in a 48-pin TSOP package. Standard control pins—chip enable (CE#), write en-

able (WE#), and output enable (OE#)—control normal read and write operations,

and avoid bus contention issues.

The device requires only a single 3.0 volt power supply for both read and write

functions. Internally generated and regulated voltages are provided for the pro-

gram and erase operations.

Simultaneous Read/Write Operations with Zero Latency

The Simultaneous Read/Write architecture provides simultaneous operation

by dividing the memory space into separate banks (see Table 2). Sector ad-

dresses are fixed, system software can be used to form user-defined bank

groups.

During an Erase/Program operation, any of the non-busy banks may be read

from. Note t hat on ly two banks can o perate simultaneous ly. The device c an im-

prove overall system performance by allowing a host system to program or erase

in one bank, then immediately and simultaneously read from the other bank, with

zero latency . This releases the system from waiting for the completion of program

or erase o perati ons.

The S29JL032H can be organized as both a top and bottom boot sector

configuration.

S29JL032H Features

The SecSi™ (Secured Silicon) Sector is an extra 256 byte sector capable of

being permanently locked by FASL or customers. The SecSi Customer Indicator

Bit (DQ6) is perman ently set to 1 i f the part has bee n custom er locked, perma-

nently set to 0 if the part has been factory locked, and is 0 if customer lockable.

This way, customer lockable parts can never be used to replace a factory locked

part.

Factory locked parts provide several options. T he SecSi Sector may store a se-

cure, random 16 byte ESN (Electronic Serial Number), customer code

(programmed through Spansion programming services), or both. Customer Lock-

able parts may utilize the SecSi Sector as bonus space, rea ding and writing like

any other flash sector, or may permanently lock their own code there.

DMS (Data Management Software) allows systems to easily take advantage

of the advanced architecture of the simultaneous read/write p roduct line by al-

lowing removal of EEPROM devices. DMS will also allow the system software to

be simplified, as it will perform all functions necessary to modify data in file struc-

tures, as opposed to single-byte modifications. To write or update a particular

piece of data (a phone number or configuration data, for example), the user only

needs to state which piece of data is to be updated, and where the updated data

is located in the system. This is an advantage compared to systems where user-

written software must keep track of the old data location, status, logical to phys-

ical translation of the da ta onto the Flas h memory devic e (or me mory devices),

ADVANCE INFORMATION

and more. Using DMS, user-written software does not need to interface with the

Flash mem ory dir ectly. Instead, the us er's softwar e acce sses t he Fla sh me mory

by calling one of only six functions.

The device offers complete compatibility with the JEDEC 42.4 sin-

gle-power-supply Flash command set standard. Comma nds are written to

the command register using standard microprocessor write timings. Reading data

out of the device is similar to reading from other Flash or EPROM devices.

The host system can detect whether a program or erase oper ation is complete by

using the device status bits: RY/BY# pin, DQ7 (Data# Polling) and DQ6/DQ2

(toggle bits). After a program or erase cycle has been completed, the device au-

tomatically returns to the read mode.

The sector erase architecture allows memory sectors to be erased and repro-

grammed without affecting the data contents of other sectors. The device is fully

erased when shipped from the factory.

Hardware data protection measures include a low V CC detector that automat-

ically inhibits write operations during power transitions. The hardware sector

protection feature disables both program and er ase operations in any combina-

tion of the sectors of memory. This can be achieved in-system or via

programming equipment.

The device offers two power-saving features. When a ddr es s es have b een stable

for a specified amount of time, the device ent ers the automatic sleep mode.

The system can al so pl ace the device into the standby mode. Power consump-

tion is greatly reduced in both modes.

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 locati on. The register is a latch

used to store the commands, along with the address and data information

needed to ex ecute 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 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 1. S29JL032H Device Bus Operations

Legend: L = Logic Low = VIL, H = Logic High = VIH, VID = 11.5–12.5 V, VHH = 9.0 ± 0.5 V, X = Don’t Care, SA = Sector

Address, AIN = Address In, DIN = Data In, DOUT = Data Out

Notes:

1. Addresses are A20:A0 in word mode (BYTE# = VIH), A20:A-1 in byte mode (BYTE# = VIL).

2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See

the “Sector/Sector Block Protection and Unprotection” section.

3. If WP#/ACC = VIL, the two outermost boot sectors remain protected. If WP#/ACC = VIH, protection on the two out-

ermost boot sectors depends on whether they were last protected or unprotected using the method described in

“Sector/Sector Block Protection and Unprotection”. If WP#/ACC = VHH, all sectors will be unprotected.

Word/Byte Configuration

The BYTE# pin controls whether the device da ta I/O pins operate in the byte or

word configuration. If the BYTE# pin is set at logic ‘1’, the device is in word con-

figur ation, DQ15– DQ0 are active an d controlled by CE# and OE#.

If the BYTE# pin is set a t logic ‘0’, the de vice is in byte configuration, and only

data I/O pins DQ7– DQ0 are ac tive and contr olled by CE# a nd OE#. The d ata I/

O pins DQ14–DQ8 are tri-stated, and the DQ15 pin is used as an input for the

LSB (A-1 ) address function .

Requirements for Reading Array Data

To read array data from the outputs, the system must drive the CE# and OE#

pins to VIL. CE# is the power control and selec ts the device. OE# is the output

control and gates a r ray data to the outp ut pins. WE# should remain at VIH. The

BYTE# pin determines whether the device outputs array data in words or bytes.

The internal state m achine is set for reading array data up on device power-up,

or after a hardware reset. This ensures that no spurious alteration of the memory

content occurs during the power transition. No command is necessary in this

mode t o obtain a rra y data. Stan dard micr oprocessor read cy cles that a ssert v alid

addresses on the device address inputs produce valid data on the device data

outpu ts . Each bank remains enab l ed for read access u n t il the command reg i ster

contents are altered.

Refer to the AC R ead-Only Operations table for timing specifications and to 14 for

the timing diagram. ICC1 in the DC Characteristics table represents the active cur-

rent specification for reading arr a y data.

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.

For program operations, the BYTE# pin determines whether the device accepts

program data in bytes or words. Refer to “Word/Byte Configuration” for more

information.

The device features an Unlock Bypass mode to facilitate faster programming.

Once a bank enters the Unlock Bypass mode, only two write cycles are required

to program a wor d or byte, inste ad of four. Th e “Byte /Wor d Pro gram Comm an d

Sequence” section has details on programming data to the device using both

standard and Unlock Bypass command sequences.

An erase operation can erase one sec tor, mu ltiple sectors, or the entire d evice.

Tables 3 and 4 ind i cat e the address space that each sector occupies. Similarly, a

“sector address” is the address bits required to uniquely select a sector. The

“Command Definitions” section has details on erasing a sector or the entire chip,

or suspending/resuming the erase operation.

The device address space is divided into four banks. A “bank address” is the ad-

dress bits required t o uniquely select a bank.

ICC2 in the DC Characteristics table represents the active current specification for

the write mode . The AC Characteristics section c ontains timing specification ta-

bles and timing diagrams for write operations.

ADVANCE INFORMATION

Accelerated Program Operation

The device offers acceler ated program operations through the ACC function. This

is one of two functions provided by the WP#/ACC pin. This function is primar ily

intended to allow faster manufacturing throughput at the factory.

If the system a sserts VHH on this pin, the device automatically enters the afore-

mentioned Unlock Bypass mode, temporarily unprotects any protected sectors,

and uses the hig her voltage on the pin to reduce the time requir ed for prog ram

operations. The system would use a two-cycle program command sequence as

required by the Unlock Bypa ss mode. Removing VHH from the WP#/ACC pin re-

turns the device to normal operation. Note that VHH must not be asserted on

WP#/ACC for operations other than accelerated programming, or device damage

may result. In addition, the WP#/ACC pin must not be left floating or uncon-

nected; inconsistent behavior of the device may result. See “Write Protect

(WP#)” on page 22. for related information.

Autoselect Functions

If the system writes the autoselect command sequence, the device enters the au-

toselect mode. The system can then read autoselect codes from the internal

read cycle timings apply in this mode. Refer to t h e Au t o se l ect Mode and Autose-

lect Command Sequence sections for more information.

Simultaneous Read/Write Operations with Zero Latency

This device is capable of reading data f rom one bank of memory while program-

ming or erasing in the other bank of memory. An erase operation may also be

suspended to read from or program to another location within the same bank (ex-

cept the sector being er ased). Fi gure 21 shows how read and wr ite cycles may be

initiated for simultaneous operation with zero latency. ICC6 and ICC7 in the DC

Characteristics table represent the current specifications for read-while-program

and read-while-erase, respectively.

When the system is not readi ng or writing to the devic e, it can place the devic e

in the 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 CM OS s ta ndby mode when the CE# and RESET# pins are

both held at VCC ± 0. 3 V. (Note that this is a more restricted voltage range than

VIH.) If CE# and RESET# are held at VIH, but not within VCC ± 0.3 V, the device

will be in the standby mode, but the standby cur rent will be grea ter. The device

requires standard access time (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 ac-

tive current until the operation is completed.

ICC3 in the DC Characteri stics table represents the standby current specification.

Automatic Sleep Mode

The automatic sleep mode minimizes Flash device energy consumption. The de-

vice automatically enables this mode when addresses remain stable for tACC +

30 ns. The automatic sleep mode is independent of the CE#, WE#, and OE# con-

trol signals. St andard address access timings provide new data when addresses

are changed. While in sleep mode, output data is latched and always available to

the system. ICC5 in t he DC Characteristics table r epresents the automatic slee p

mode current specification.

RESET#: Hardware Reset Pin

The RESET# pin provides a ha rdware method of res etting the device to reading

array data. When the RESET# pin is driven low for at least a period o f tRP, the

device immediately terminates any operation in progress, tristates all output

pins, and ig nores a ll read /wri te com mands for th e dur ation of t he RES ET# pul se.

The device also resets the inter n al st at e machine to reading array data. The op-

eration that was interrupted should be reinitiated once the device is ready to

accep t an o t h er command seque n ce , to ensure data integrity.

Current is reduced for the duration of the RESET# puls e. When RESET# is hel d

at V SS±0.3 V, the device draws CMOS stan dby c urr ent (ICC4). If RESET# is held

at VIL but not within VSS±0.3 V, the standby current will be greater.

The RESET# pin ma y be tied to the system re set circu itry. A system reset would

thus also reset the Flash memory, enabling the system to read the boot-up firm-

ware from the Flash mem ory.

If RESET# is asserted during a program or erase operation, the RY/BY# pin re-

mains a “0” (busy) until the inte rnal r es et operation is complete , which requir es

a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/

BY# to determine whether the reset operation is complete. If RESET# is asserted

when a program or erase operation is not executing (RY/BY# pin is “1”), the reset

operation is completed within a time of tREADY (not during Embedded Algorithms).

The syst em can read data tRH after the RESET# pin returns to VIH.

Refer to the AC Characteristics tab les for RESET# parameters and to 15 for the

timin g diagram.

Output Disable Mode

When the OE# input is at VIH, output from the device is disabled. The output pins

are placed in the high impedance state.

Autoselect Mode

The autoselect mode provides manufacturer and device identification, and sector

protection verificati on, through identifier codes out put on DQ 7–DQ0 . This mode

is primarily intended for programming equipment to automatically match a device

to be programmed with its corresponding programming algorithm. However, the

autos elect co de s can a lso be acces sed in-syst em th roug h the co mma nd reg iste r.

When using programming e quipment, the autose lect mode requires VID on ad-

dress pin A9. Address pins must be as shown in Table 5. In addition, when

verifying sector protection, the sector address must appear on the appropriate

highest order address bits. Table 5 shows the remaining address bits that are

don’t care. When all necessary bits have been set as required, the programming

equipmen t may then r ead the c or res pond ing identifier code on DQ7–DQ0. How-

ever, the au toselect codes can als o be accesse d in-syst em through the command

without access to high voltage on the A9 pin. The command sequence is illus-

trated in Table 13. Note that if a Bank Address (BA) on address bits A20, A19 and

A18 is asserted during the third write cycle of the autoselect command, the host

system can read autoselect data from that bank and then immediately read array

data from another bank, without exiting the autoselect mode.

To access th e autoselec t codes in-syst em, the host system can issue the autose -

lect comm and via the comma nd register, a s shown in Table 13. This method does

not require VID. Refer to the Autoselect Command Sequence section for more

information.

Write Protect (WP#)

The W rite Protect function provides a hardware method of protecting certain boot

sectors with ou t using V ID. This function is one of two p rovided by t he WP#/ACC

pin.

If the system asserts VIL on the WP#/ACC pin, the de vice disables program and

erase functions in the two outermost 8 Kbyte boot sectors independently of

whether those sectors were protected or unprotected using the method described

in “Sector/Sector Block Protection and Unprotection”. The two outermost 8 Kbyte

boot sectors are the two sectors containing the lowest addresses in a bottom-

boot-configured device, or the two sectors containing the highest addresses in a

top-boot-configured device.

If the system as serts VIH on the WP#/ACC pin, the device reverts to whether the

two outermost 8K Byte boot sectors were last set to be protected or unprotected.

That is, sector protection or unprotection for these two sectors depends on

whether they wer e last pr otected or unprotected using the method de scribed in

“Sector/Sector Block Protection and Unprotection”.

Note that the WP#/ACC pin must not be left floating or unconnected; inconsistent

behavior of the device may result.

Temporary Sector Unprotect

(Note: For the following discussion, the term “sector” applies to both sectors and

sector blocks. A sector block consists of two or more adjacent sectors that are

This feature allows temporary unprotection of previously protected sectors to

change data in-system. The Temporary Sector Unprotect mode is activated by

setting the RESET# pin to VID. During this mode, formerly protected sectors can

be programmed or erased by selecting the sector addresses. Once VID is removed

from the RESET# pin, all the previously protected sectors are protected ag ain.

SecSi™ (Secured Silicon) Sector

Flash Memory Region

The SecSi (Secured Silicon) Sector feature provides a Flash memor y region that

enables permanent part identification through an Electronic Serial Number

(ESN). The SecSi Sector is 256 bytes in length, and uses a SecSi Sector Indicator

Bit (DQ7) to indicate whether or not the SecSi Sector 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 product is available with the Se cSi Sector either factor y locked or customer

lockable. The fa ctory-locked version is always protected when sh ipped from the

factory, and has the SecSi (Secure d Silico n) Sect or Indica tor Bit perman ently se t

to a “1.” The customer-lockable version is shipped with the SecSi Sector unpro-

tected, allowing custome rs to utilize the tha t sector in any manner they choose.

The customer-lockable version has the SecSi (Sec ured Silicon) Sector Indicator

Bit permanently set to a “0.” Thus, the SecSi Sec tor Indicator Bit p revents cus-

tomer-lockable devices from being used to replace devices that are factory

locked. The SecSi Customer Indicator Bit (DQ6) is permanently set to 1 if the part

has been customer locked, permanently set to 0 if the part has been factory

locked, and is 0 if customer lockable.

The system accesses the SecSi Sector Secure through a command sequence (see

“Enter SecSi™ Sec tor/Exit SecS i Sector Comm and Sequence ” ). After the system

has written the Enter SecSi Sector command sequence, it may read the SecSi

Sector by using the addresses normally occupied by the boot sectors. This mode

of operation continues until the system issues the Exit SecSi Sector command se-

quence, or unt il powe r is removed from the device. On powe r-up, or following a

hardware reset, the device reve rts to sending co mmands to the fir st 256 bytes of

Sector 0. Note that the ACC function and unlock bypass modes are not available

when the SecSi Sector is enabled.

Factory Locked: SecSi Sector Programmed and Protected At the Factory

In a factory locked device, the SecSi Sector is protected when the device is

shipped from the factory. The SecSi Sector cannot be modified in any way. The

device is preprogrammed with both a random number and a secure ESN. The 8-

word random number is at addresses 000000h–000007h in word mode (or

000000h–00000Fh in byte mode). T he s ec ure ESN is programmed in the next 8

words at addresses 000008h–00000Fh (or 000010h–00001Fh in byte mode). The

device is available preprogr ammed with one of the following:

A random, secure ESN only

Customer code through Spansion programmi ng services

Both a random, secure ESN and customer code t hrough Spansion program-

ming services

Contact an your local sales office for details on using Spansion programming

services.

Customer Lockable: SecSi Sector NOT Programmed or Protected At the Factory

If the se curity feature is no t re quired, the SecSi Secto r can b e treated as an ad-

ditional Flash memory space. The SecSi Sector can be read any number of times,

but can be programmed and locked only once. Note that the accelerated pro-

gramming (ACC) and unlock bypass functions are not available when

programming the SecSi Sector.

26 S29JL032H S29JL032HA0 May 21, 2004

ADVANCE INFORMATION

The SecSi Sector area can be protected using one of the following procedures:

Write the three-cycle Enter SecSi Sector Region command sequence, and

then follow the in-system sector protect algorithm as shown in Figure 2, ex-

cept that RESET# may be at either VIH or VID. This allows in-system protec-

tion of the SecSi Sector Region without raising any device pin to a high

voltage. Note that this m e thod is only a pplicable to the SecSi Se ctor.

To verify the protect/unprotect status of the SecSi Sector, follow the algo-

rithm shown in Figure 3.

Once the SecSi Sector is locked and verified, the system must write the Exit SecSi

Sector Region command sequence to return to reading and writing the remainder

of the array.

The S e cSi S ect or lo ck must be used w ith cau tion si nce , onc e lo cked, the re i s no

procedure available for unlocking the SecSi Sector area and none of the bits in

the SecSi Se ct o r memory space can be modified in any way.

Hardware Data Protection

The command sequence requirement of unlock cycles for programming or erasing

provides data protection against inadvertent writes (refer to Table 13 for com-

mand 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.

Low VCC Write Inhibit

When VCC is less than VLKO, the device does not accept any write cycles. This pro-

tects d at a d u ring 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 gr eater than VLKO.

Write Pulse “Glitch” Protection

Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write

cycle.

Logical Inhibit

W rite 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.

Power-Up Write Inhibit

If WE# = CE# = VIL a nd 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.

Common Flash Memory Interface (CFI)

The Comm on Fl ash Int erface (CF I) spec if icati on outl ine s devi ce and host syste m

software interrogation handshake, which allows specific vendor-specified soft-

ware algorithms to be used for entire families of devices. Software support can

then be device-independent, JEDEC ID-independent, and forward- and back-

ward-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 in word mode (or address AAh in byte mode), any

time the device is ready to read array data. The system can read CFI information

at the addresses given in Tables 9–12. To terminate reading CFI data, the system

must write the reset command.The CFI Query mode is not accessible when the

device is executing an Embedded Program or embedded Er ase algorithm.

The system can also write the CFI query command when the device is in the au-

toselect mode. The device enters the CFI query mode, and the system can read

CFI data at the addresses given in Tables 9–12. The system must write the reset

command to reading arr ay data.

ADVANCE INFORMATION

Command Definitions

Writing specific address and data commands or sequences into the command

sequences. Writing incorrect address and data values or writing them in the im-

proper 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 latche d on the rising edge of WE# or CE#, whichever happens

first. R e fer to the AC Characteristics section fo r t iming diagrams.

Reading Array Data

The device is automatical ly set to reading array data after device power-up. No

commands are requir ed to retrieve data. Each bank is ready to read ar ray data

after completing an Embedded Program or Embedded Erase algorithm.

After the device accepts an Erase Suspend command, the corresponding bank

enters the erase-suspend-read mode, after which the system can read data from

any non-erase-suspended sector within the same bank. The system can read

array data using t he standard read timing, except that if it reads at an address

within erase-suspended sectors, the device outputs status data. After completing

a programming operation in the Erase Suspend mode, the system may once

again read array data with the same exception. See the Erase Suspend/Erase R e-

sume C ommands section for more information.

The system must issue the reset command to return a bank to the read (or erase-

suspend-read) mode if DQ5 goes high during an active program or erase opera-

tion, or if the bank is in the autoselect mode. See the next section, Res et

Command, for more information.

See also Requirements for Reading Array Data in the Device Bus O perati ons sec-

tion for more information. The Read-Only Operations table provides the read

parameters, and 14 shows the t i mi ng diagr am.

Reset Command

Writing the res et command r esets the b anks to th e read or erase-sus pend-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 bank to which the sys-

tem was writing to the read mode. Once erasure begins, however, the device

ignores reset commands until the operation is complete.

The reset comm and may be written between the sequ ence cycles in a program

command sequence befo re programming be gins. This res ets the bank to whic h

the system was writing to the read mode. If the program com ma nd s equence is

written to a bank that is in the Erase Suspend mode, writing the reset command

returns that bank to the e rase-suspend-read mode. Onc e programming b egins,

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 autosele ct mode, the reset command must be

written to return to the read mode. If a bank entered the autoselect mode while

in the Erase Suspend mode, writing the reset command returns that bank to the

erase-suspend-read mode.

32 S29JL032H S29JL032HA0 May 21, 2004

ADVANCE INFORMATION

If DQ5 goes high during a program or erase operation, writing the reset command

returns the banks to the read mode (or erase-suspend-read mode if that bank

was in Erase Suspend).

Autoselect Command Sequence

The autoselect command sequence allows the host system to access the manu-

facturer and device codes, and determine whether or not a sector is protected.

The autoselect command sequenc e may be written to an address within a bank

that is either in the read or erase-suspend-read mode. The autoselect command

may not be written while the device is actively programming or erasing in another

bank.

The autoselect command sequence is initiated by first writing two unlock cycles.

This is followed by a thir d write cycle that contains the bank address and the au-

toselect command. The bank then enters the autoselect mode. The system may

read any number of autoselect codes without reinitiating the command sequence.

Table 13 shows the address and data requirements. To determine sector protec-

tion information, the system must write to the appropriate bank address (BA) and

secto r address (SA). Tables 3 and 4 show the address rang e and b ank number

associated with each sector.

The system must write the reset command to return to the read mode (or era se-

sus pend-r ead mode i f the ba nk was previously in E rase Suspend).

Enter SecSi™ Sector/Exit SecSi Sector

Command Sequence

The SecS i S ector region provid es a s ec u re d da ta area containing a random , six -

teen-byte electronic serial number (ESN). The system can access the SecSi

Sector re gion by issu ing the three-cycle Enter SecSi Secto r command se qu e n ce.

The device continues to access the SecSi Sector region until the system issues

the four -c y cle Exit SecSi Se c tor com man d se quence . T he Exi t SecSi Sec tor com-

mand sequ ence returns the device to normal operation. The SecSi Sector is not

accessible when the device is executing an Embedded Program or embedded

Erase algorithm. Table 13 shows the address and data requirements for both com-

mand sequences. See also “SecSi™ (Secured Silicon) Sector

Flash Memory Region” for further information. Note that the ACC function and un-

lock bypass modes are not available when the SecSi Sector is enabled.

Byte/Word Program Command Sequence

The system may program the device by word or byte, depending on the state of

the BYTE# pin. Programming is a four-bus-cycle operation. The program com-

mand 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 requir ed to

provide further c ontrols or timings. The device a utomatically provides interna lly

generated program pulses and verifies the programmed cell margin. Table 13

shows the address and data requirements for the byte program command

sequence.

When the Embedd ed Progra m algorithm is comp lete, that bank then retur ns to

the read mo de and addr esses a re no longer la tched. Th e system c an determi ne

the status of the program operation by using DQ7, DQ6, or RY/BY#. R efer to the

Write Operation Status section for information on these status bits.

May 21, 2004 S29JL032HA0 S29JL032H 33

ADVANCE INFORMATION

Any commands written to the device during the Embedded Program Algorithm

are ignor ed. Note that a hardware reset immed iately termina tes the prog ram

operation. The program command sequence should be reinitiated once that bank

has returned to the read mode, to ensure data integrity . Note that the SecSi Sec-

tor, autoselect, and CFI functions are unavailable when a program operation is in

progress.

Programming is allowed in any sequence and across sector boundaries. A bit

cannot be programmed from “0” back to a “1.” Attempting to do so may

cause that bank to set DQ5 = 1, or cause the DQ7 and DQ6 status bits to indicate

the oper ation was succ essful. However, a succeeding read will show that the data

is still “0.” Only erase operations can conv ert a “0” to a “1.”

Unlock Bypass Command Sequence

The unlock bypass feature allows the system to program bytes or words to a bank

faster than using the standard pr ogram command sequence. 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. That bank

then enters th e unlock bypass mode. A two-c ycle unlock bypass program com-

mand sequence is all that is required to program in this mode. The first cycle in

this sequence contains the unlock bypass program command, A0h; the second

cycle con tain s th e p rog ram addr ess a nd d ata. Addit iona l data is pr ogrammed in

the same manner. This mode dispenses with the initial two unlock cycles required

in the standard p rogram command sequence, resu lting in faster total program-

ming time. Table 13 shows the requirements for the command sequence.

During the unlock bypass mode, only the Unlock Bypass Program and Unlock By-

pass Reset commands are valid. To exit the unlock bypass mode, the system

must issue the two-cycle unlock bypass reset command sequence. (See Table

12).

The device offers accelerated program operations through the WP#/ACC pin.

When the system asserts VHH on the WP#/ACC pin, the device automatically en-

ters the Unlock Bypa ss mode. The system may then write the two-cycle Unlock

Bypass program command sequence. The devi ce uses the higher voltage on the

WP#/ACC pin to accelerate the operation. Note that the WP#/ACC pin must not

be at VHH for any operation other than accelerated programming, or device dam-

age may result. In addition, the WP#/ACC pin must not be left floating or

unconnected; inconsistent behavior of the device may result.

gram Operations table in the AC Characteristics section for parameters, and

Figure 4. Program Operation

Chip Erase Command Sequence

Chip erase is a six bus cy cle operation. The chip erase command sequence is ini-

tiated 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 t o preprogram prior t o erase. The Embedde d Era se algorithm a uto-

matically 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 tim-

ings during these oper ations. Table 13 shows the address and data requirements

for the chip erase command sequence.

When the Embedded Erase a lgor ithm is co mplete, tha t ba nk r etur ns t o the r ead

mode and addresses are no longer latched. The system can determine the status

of the erase operation by using DQ7, DQ6, DQ 2, or RY/BY#. Re fer to the Write

Operation Status section for information on these status bits.

Any commands written during the chip erase operation are ignored. However,

note that a hardware reset immediately terminates the erase operation. If that

occur s, the chip erase comma nd sequenc e s hould be r einitiated once that bank

has returned to reading array data, to ensure data integrit y. Note that the SecSi

Sector, autoselect, and CFI functions are unavailable when an erase operation is

in progress.

Operations tables in the AC Characteristics section for parameters, and Figure 20

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 addi-

tional unlock cycles are written, and are then followed by the address of the

sector to be erased, and the sector erase command. Table 13 shows t he a d dr es s

and data requirements for the sector erase command sequence.

The device does not require t he system to preprogram prior to eras e. The Em-

bedded Erase algorithm automatically programs and verifies the entire sector 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 com mand sequ ence is wri tten, a secto r eras e time-out of 80 µs occurs.

During the time-out period, additional sector addresses and sector erase com-

mands may be written. 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 80 µs, 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. Any com-

mand other than Sector Erase or Erase Suspend during the time-out

period resets that bank to the read mode. The system must rewrite the com-

mand sequence and any additional addresses and commands.

The system can monitor DQ3 to determine if the sector erase timer has timed out

(See the s ectio n on DQ 3: Sec tor Er ase T imer.). T he ti me-ou t begin s from the r is-

ing edge of the final WE# or CE# pulse (first rising edge) in the command

sequence.

When the Embedded Erase algorithm is complete, the bank returns to reading

array data and addres ses are no longer latche d. Note that while the Embedded

Erase operation is in progress, the system can read data from the non-erasing

bank. The system can determine the status of the erase operation by reading

DQ7, DQ6, DQ2, or RY/BY# in the erasing bank. R efer to the Write Operation Sta-

tus section for information on these status bits.

Once the sector erase operation has begun, only the Erase Suspend command is

valid. All other commands are ignored. However, note that a hardware reset im-

mediately terminates the erase operation. If that occurs, the sector erase

command sequence should be reinitiated once that bank has returned to reading

array data, to en sure data integrity. Note that the SecSi Sector, autoselect, and

CFI functions are unavailable when an erase operation is in progress.

5 illustrates the algorithm for the erase operation. Refer to the Erase and Program

Operations tables in the AC Characteristics section for parameters, and Figure 20

section for timing diagrams.

Figure 5. Erase Operation

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 sect or not selected

for er asure . The b ank ad dress is requ ired when writin g this command . This com -

mand is valid only during the sector erase operation, including the 80 µs 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. The bank address must contain one of the sectors currently selected

for erase.

When the Erase Suspend command is written during the sector erase operation,

the device re quires a maximum of 20 µs to s uspend the erase operation. How-

ever, when the Erase Suspend command is written during the sector erase

time-out, the de vice immediately terminates the tim e-out period and s uspends

the erase operation.

After the erase operation has been suspended, the bank enters the erase-sus-

pend-rea d mod e. The system can rea d da ta fr om or pr ogram data to any sector

not selected for erasure. (The device “erase suspends” all sectors selected for

erasure.) Reading at any add ress within e rase-susp ended se ctors pr oduces sta-

tus information on DQ7–DQ0. The system can use DQ7, or DQ6 and DQ2

together, to determine if a sector is actively er asing or is er ase-suspended. Refer

ADVANCE INFORMATION

Write Operation Status

The device provides several bits to determine the status of a program or erase

operation: DQ2, DQ3, DQ5, DQ6, and D Q7. Table 14 and the following subsec-

tions describe the function of the se bits. DQ7 and DQ6 each o ffer 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 has been

completed.

DQ7: Data# Polling

The Data# Polling bit, DQ7, indicates to the host system whether an Embedded

Program or Erase al gor ithm is in progr ess or complete d, or whether a bank is in

Erase Suspend. Data# P olling is valid after the rising edge of the final WE# pulse

in the co mmand sequence.

During the Em bedded Program a lgorithm, the devic e outputs on DQ7 the c om-

plement of the datum programmed to DQ7. This DQ7 status also applies to

programming during Erase Suspend . Whe n the Embedde d Program alg ori thm is

complete, the device outputs the datum programmed to DQ7. The system must

provide the program address to read valid status information on DQ 7. If a p ro-

gram address falls within a protected sector, Data# Polling on DQ 7 is active for

approximately 1 µs, then that bank 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 bank enters the Erase

Suspend mode, Data# Polling produces a “1” on DQ7. The system must provide

an address withi n any of the sectors selected for erasure to read valid status in-

formation on DQ7.

After an erase command sequence is written, if all sectors selected for erasing

are protected, Data# Polling on DQ7 is active for approximately 100 µs, then the

bank returns to the read mode. If not all selected sectors are protected, the Em-

bedded 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 pro tected sector, the status may not be valid.

When the system detects DQ7 has changed from the complement to true data,

it can read valid data at DQ15–DQ0 (or DQ7–DQ0 for x8-only device) on the fol-

lowing read cycles. Just prior to the completion of an Embedded Program or Erase

operation, DQ7 may change asynchronously with DQ15–DQ8 (DQ7–DQ0 for x8-

only device) 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 r ead the status or valid data.

Even if the device has completed the program or erase operation and DQ7 has

valid data, the data outputs on DQ15–DQ0 may be still invalid. Valid data on

DQ15–DQ0 (or DQ7–DQ0 for x8-only device) will appear on successive read

cycles.

Table 14 sho ws the outp uts for Dat a# P olling on DQ7. 6 shows the Data# P olling

algorithm. 22 in the AC Characteristics section shows the Data# Polling timing

diagram.

the rising edge of the final WE# pulse in the comm and 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 (Bus y), 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 sta ndby mode, or one of the banks is in the

erase-suspend-read mode.

Table 14 shows the outputs for RY/BY#.

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 has entered the Erase Suspend

mode. Toggle Bit I m ay b e re ad at an y addre ss , and is valid afte r the ris ing e dge

of the final WE# pulse in the command sequence (prior to the program or erase

operation), and during the sector er ase time-out.

During an Embedded Program or Erase algorithm operation, successive read cy-

cles 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 100 µs, then returns to reading

array data. If not all selected sectors are protected, the Embedded Erase algo-

rith m erases the u nprotec ted secto rs, and ig nores th e selec ted sector s that ar e

protected.

The system can use DQ6 and DQ2 together to determine whether a sector is ac -

tively erasing or is erase-suspended. When the device is actively erasing (that is,

the Embedde d Eras e algor ithm is in progress), DQ6 toggles. W hen the device e n-

ters the Erase Suspend mode, DQ6 stops toggling. However, the system must

also use DQ2 to determine which sectors are erasing or erase-suspended. Alter-

natively, the system can use DQ7 (see the subsection on DQ7: Data# P olling).

If a program address falls within a protected sector, DQ6 toggles for approxi-

mately 1 µs 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.

ADVANCE INFORMATION

DQ2 toggl es when th e system reads at addr esses wi thin tho se sect ors that ha ve

been 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 14 to compare outputs for DQ2 and DQ6.

7 shows the toggle bit algorithm in flowchart form, and the section “DQ2: Toggle

Bit II” explains the algorithm. See also the DQ6: Toggle Bit I subsection. 23

shows the toggle bit timing diagram. 24 shows the differences between DQ2 and

DQ6 in graphical form.

Reading Toggle Bits DQ6/DQ2

Refer to 7 for the following discussion. Whenever the system initially begins read-

ing toggle bit status , it must read DQ15–DQ 0 (or DQ7–DQ0 for x8-only device)

at least twice in a row to determine whether a toggle bit is toggling. T ypically, 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 tog gling , the devic e has c om plete d the program

or erase operation. The system can read array data on DQ15–DQ0 (or DQ7–DQ0

for x8-only device) 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 the section on DQ5). 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 has suc-

cessfully completed the program or erase operation. If it is still toggling, the

devic e di d not com ple te d the ope rati on su cc essf ul ly, an d t he s yst em m us t wri te

the reset command to return to reading array data.

The remaining scenario is that the system initially determines that the toggle bit

is toggling and DQ5 has not gone high. The system ma y continue to monitor the

toggle bit and DQ5 through successive read cycles, determining the status as de-

scribed in the pr evious paragraph. Alterna tively, it may choose to per form other

system tasks. In this case, the system must start at the beginning of the algo-

rithm when it returns to determine the status of the operation (top of 7).

DQ5: Exceeded Timing Limits

DQ5 indic ates whethe r the program or erase time has exceeded a specified in-

ternal pulse count limit. Under these conditions DQ5 produces a “1,” indicating

that the program o r erase cy cle was not su ccessfully co mpleted.

The device may output a “1” on DQ5 if the system tries to program a “1” to a

location that wa s previously programmed to “0.” Only an erase operation can

change a “0” back to a “1.” Unde r this condit ion, the device hal ts the opera-

tion, and when the timing limit has been exceeded, DQ5 produces a “1.”

Under both these conditions, the system must write the reset command to return

to the read mo de (or to the erase-s uspend-read mo de if a bank was previous ly

in the erase-suspend-progr am mode).

DQ3: Sector Erase Timer

After writing a sector erase command sequence, the system may read DQ3 to de-

termine whether or not erasure has begun. (The sector erase timer does not

44 S29JL032H S29JL032HA0 May 21, 2004

ADVANCE INFORMATION

apply to the c hip erase comma nd.) If ad ditio nal sect ors are se lect ed for er asu re,

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 as-

sumed to be less than 50 µs, the system need not monitor DQ3. See also the

Sector Erase Command Sequence section.

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 has accepted

the command sequence, and then read DQ3. If DQ3 is “1,” the Embedded Erase

algorithm has begun; all further commands (except Erase Suspend) are ignored

until the erase operation is complete . If DQ3 is “0,” the d evice will accept addi-

tional sect or erase comm ands. To ensur e the command has been ac cepted, th e

syste m software sh ould chec k the status of DQ3 p rior to and fol lowing each su b-

seque nt se ctor e rase c omman d. If DQ3 is high on t he s econd stat us che ck, t he

last command might not have been accepted.

Table 14 shows the status of DQ3 relative to the other status bits.

Ta bl e 1 4 . Write Operation Status

Notes:

1. DQ5 switches to ‘1’ when an Embedded Program or Embedded Erase operation has exceeded the maximum timing

limits. Refer to the section on DQ5 for more information.

2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further

details.

3. When reading write operation status bits, the system must always provide the bank address where the Embedded

Algorithm is in progress. The device outputs array data if the system addresses a non-busy bank.

ADVANCE INFORMATION

Erase And Programming Performance

Notes:

1. Typical program and erase times assume the following conditions: 25°C, VCC = 3.0 V, 100,000 cycles; checkerboard data

pattern.

2. Under worst case conditions of 90°C, VCC = 2.7 V, 1,000,000 cycles.

3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes

program faster than the maximum program times listed.

4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.

5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See

Table 13 for further information on command definitions.

6. The device has a minimum cycling endurance of 100,000 cycles per sector.
