General Description
The S29AL032D is a 32 m egabit, 3.0 volt-only flash memory device, org anized as 2,097,152
words of 16 bits each or 4,194,304 bytes of 8 bits each. W ord mode data appears on DQ0-DQ15;
byte mode data appears on DQ0-DQ7. The device is designed to be programmed in-sys tem with
the standard 3.0 volt VCC supply , and can also be pro grammed in standard EPROM programmers.
The device is available with access times as fast as 70 ns. The devices are offered in 40-pin TSOP,
48-pin TSOP and 48-ball FBGA packages. Standard control pins- chip enable (C E#), write enable
(WE#), and output enable (OE #)-control nor mal read and write operations, an d avoid bus con
tention issu e s.
The device requires only a single 3.0 volt power supply for both read and write functions. Internally generated and regul a ted voltages are provided for the pro -gram and erase operations.
S29AL032D Features
The Secured Silicon Sector is an extra sector capable of bei ng permanently loc ked by Spansi on
or customers. The Secured SiliconIndicator Bit (DQ7) is permanently set to a 1 if the part is
factory locked, and set to a 0 if customer lockable. This way, customer lockable parts can never
be used to replace a factory locked part. Note that the S29AL032D has a Se cured Silicon Sector size of 128 words (256 bytes).
Factory locked pa rts provi de sev eral opt ions. The S ecured Si licon Sec tor may store a se cure, r an dom 16 byte ESN (Electronic Seri al Number), cu stomer code (progr ammed through t he Spansion
programming service), or both.
The S29AL032D is entirely command set compatible with the JEDEC single-p ower-supply Flash standard. Commands are written to the command register using standard microprocessor
write timings. Register contents serve as input to an internal state-machine that controls the
erase and progra mming circuit ry. W rite cy cles als o internal ly latch addre sses and dat a needed for
the programming and erase operations. Reading data out of the device is similar to reading from
other Flash or EPROM devices.
Device programming occu rs by executing the pro gram command sequence. Thi s initiates the Em-bedded Program algorithm—an internal algo rith m tha t aut om atica lly ti mes the p rog ram pu lse
widths and verifies proper cell margin. The Un lock Bypass mode f aci li tat es f ast er pro gr amm ing
times by requiring only two writ e cycles to program data i nstead of four.

Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithm—an internal algori thm tha t aut oma tica lly pr epro grams th e array (if it is not al
ready programmed) before executing the eras e operation. During erase, the dev ice automatically
times the erase pulse widths and verifi es pr oper cell margin.
The host system can detect whether a program or erase operation is complete by observing the
RY/BY# pin, or by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits.
gram or erase cycle has been completed, the devi ce is ready to read array data or accept another
command.
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.
Hardware data protection measures include a low VCC detector that automatical ly inhibits write
operations during power transitions. The hardware sector protection feature disables both
program and erase oper ations in an y combination of t he sectors of memory. This can be achieved
in-system or via programmin g equipment.

Advance Information
The Erase Suspend/Erase Resume feature en ables the user to put erase on hold for any period
of time to rea d data from, or pro gram data to, any se ctor th at is n ot selec ted for erasure. True
background erase can thus be achieved.
The hardware RESET# pin terminates any operation in progress and resets the internal state
machine to reading array data. The RESET# pin may be tied t o the system reset circ uitry. A sys
tem reset would thus also reset the device, enablin g the system microprocessor to read the
boot-up firmware from the Flash memory.
The device offers two power-saving features. When addresses have been stable for a specified
amount of time, the d evice enter s the automatic sleep mode. The system ca n also place th e
device into the standby mode. Power consumption is greatly reduced in both these modes.
The Spansion Flash technology combines years of Flash memory manufacturing experience to
produce the highest levels of qua lity, reliability and cost effectiveness. The de vice electrically
erases al l bi ts wit hin a se cto r s imu lta neo us ly v ia F owl er- Nordheim tunneling. The data is
programmed using hot electron injection.
Special handling is required for Flash Memory products in FBGA packages.
Flash memory devices in FBGA packages may be da maged if exposed to ultr asonic cleanin g meth-
ods. The package and/or data integrity may be compromised if the package body is exposed to
temperatures above 150°C for pr olonged periods of time.

The autoselect mode provides manufacturer and device identification, and sector protection v erification, through identifie r codes output on DQ7–DQ0. This mode is primarily intended for
programming equipment to automatic ally match a device t o be programmed with it s correspond

through the command register.
When using programming equipment, the autoselect mode requires VID (11.5 V to 12.5 V) on
address pin A9. Address pins A6, A1, and A0 must be as shown in

Advance Information
The device is shipped with all sectors unprotected. Spansion offers the option of programming
and protecting sectors at its factory prior to shipping the device through the Spansion Express
Flash™ Servi ce. Contact a Spansion representative for fur ther details.
It is possible to determine whether a sector is protected or unprotected. See “Autoselect Mode”
for detail s.
Sector protection/unprotection can be implemented via two methods.
The primary method requires VID on the RESET# pin only, and can be implemented either i n-sys-
tem or via programming equipment. Figure 2, on page 25 shows the algorithms and Figure 26,
on page 59 shows the t imin g di agr a m. T his met hod us es sta ndard mi cro proc es sor bus c ycl e t im -
ing. For sector unprote ct, all unpro tec ted se ctor s must first be prot ected prior to the fir st sect or
unprotect write cycle.
The alternate method intended only for programming equipment require s VID on address pin A9
and OE#. This method is compatible with programmer routines written for earlier 3.0 volt-only
Spansion flash devi ces. Detail s on this method are provided in a su pplement, publicati on number

The Secured Silicon Sector feature provides a 256 byte Flash memory region that enables permanent part identification th rough an Electronic Seri al Number (ESN). The Secured Silicon Sect or
uses a Secured Si li co n Se c t o r Indicator Bit ( DQ 7 ) to indicate whethe r o r no t the Secured Silico n
Sector is locked when shipped fro m the factory . This bit is permanentl y set at the factory and can
not be changed, which prev ents cloning of a factory locked part. This ensures the security of the
ESN once the product is shipped to the field.
Spansion offers the device with the Secured Silicon Sector eit her factory locked or customer lock able. The factory-locked version is always protected when shipped from the factory, and has the
Secured Silicon Sector Indicator Bit permanently set to a 1. The customer-lockable version is
shipped with the Secured Silicon Sector unprotected, allowing customers to utilize the that sector
in any manner they choose. The customer-lockable version has the Secured Si licon Sect or Ind i
cator Bit p ermanently se t to a 0. Thus, the Secured Silicon Sector Indicator Bit prevents
customer-lockable devices from bein g used to replace devices that are factory locked.
The system a ccesses the Secur ed Silic on Sector through a comm and sequ ence (s ee Enter Se-
cured Silicon Sector/Exit Secured Silicon Sector Command Sequence on page 32). After the
system writes the En ter Sec ured Si licon Sect or co mmand seque nce, it may rea d the Secur ed Sil icon Sector by using the addres ses normally occupi ed by the boot secto rs. This mode of oper ation
continues until the system issues the Exit Secured Silicon Sector command sequence, or until
power is removed from the device. On power-up , or following a hardware reset, the devic e reverts
to sending commands to the boot sectors.

Factory Lock ed : Se cured Silicon Sector P rogrammed
and Protected at the Factory
In a factory lock ed device, the Secured Si licon Sector i s protected when the devi ce is shipped from
the factory . The Secured Silic on Sector cannot be modified in any w ay . The device is av ailable preprogrammed with one of the following:
A random, secure ESN only
Customer code through the ExpressFlash service
Both a random, secure ESN and customer code through the ExpressFlash service.
In devices that have an ESN, a Bottom Boot device has the 16-byte (8-word) ESN in sector 0 at
addresses 00000h–0000Fh in b yte mode (or 00000h–00007h in word mode). In t he Top Boot de
vice the ESN is in sector 70 at addresses 3FFF00h–3FFF0Fh in byte mode (or 1FFF80h–1FFF87h
in word mode). In the Uniform device the ESN is in sector 63 at addresses 3FFF00h-3FFF0Fh in
byte mode (or 1FFF80h-1FFF87h in word mode).
Customers may opt to ha ve their code programmed by Spansion throug h the Spansion ExpressFlash service. Spansion programs the customer’s code, with or without the random ESN. The
devices are then shipped from the Spansion factory with the Secured Silicon Sector permanently
locked. Contact a Spansion representativ e for details on usin g the Spansion ExpressFlash servi ce.
Customer Lockable: Secured Silicon Sector NOT Programmed

The customer lockable versi on allows the Secured Silicon Sector to be progr ammed once and then
permanently locke d after i t sh ips fr om Span sion. Note that the acc elerated p rogramm ing ( ACC )

Reset Command
Writing the reset co mmand to the device resets the device t o reading arra y data. Address bits are
don’t care for this command.
The reset command may be written between the sequence cycles in an erase command sequence
before erasing begins. This res ets the device to reading array d ata. Once erasure begins, howeve r ,
the device ignores reset commands until the operation is c omplete.
The reset command may be written between the sequence cycles in a program command sequence before progra mmin g begins. This resets the device to reading array data (also appli es to
programming in Erase Suspend 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 re adin g
array data (also applies to autoselect during Erase Suspend).
If DQ5 goes high during a program or erase operation, writing the reset command returns the
device to reading array data (also applies during Erase Suspend).
Autoselect Command Sequence
The autoselect c ommand se quence allo ws the hos t system to acce ss the manu facturer an d devices codes, and determine whether a sector is protected. Table 17 on page 38 shows the address
and data requirements. This method is an alternative to that shown in Table 8 on page 20, which
is intended for PROM programmers and requires VID on address bit A9.
The autoselect command sequence is initiated by writing two unlock cycles, followed by the autoselect command. The device t hen enters the aut oselect m ode, and the s ystem may re ad at any
address any number of times, without initiating another command sequence.
A read cycle at address 0XXX00h retrieves the manufacturer code. A read cycle at address
0XXX01h returns the device code. A read cycle containing a sector address (SA) and the address
02h in word mode (or 04h in byte mode) returns 01h if that sector is protected, or 00h if it is
unprotected. Refer to
The system must write the reset command to exit the autose lect mode and retu rn to reading

Any commands written to the device during the Embedded Program Algorithm are ignored. Note
that a hardware reset immediately terminates the programming operation. The Byte Program

Unlock Bypass Command Sequence
The unlock bypass feature all ows the syst em to progr am bytes or words to the devi ce faster than
using the standard program command sequence. The unlock bypass command sequence is initi
ated by first writing two un lock cycles. T his is followed by a th ird write cycle c ontaining the unlo ck
bypass command, 20h. The device then enters the unlock bypass mode. A two-cycle unlock by
pass program command 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 contains
the program address and data. Additional data is programmed in the same manner. This mode
dispenses with the initial two unlock cycles required in the standard program command sequence ,
resulting in faster t o t al programming time.

During the unlock bypass mode, o nly the U nlock Bypass Progr a m and Unlo ck Bypass Reset commands are valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock

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 preprogram pri or to erase. The E mbedded Erase algori thm
automatically preprograms and verifies the entire memory for an all zero data pattern prior to
electrical erase. The system is not requir ed to pr ovide an y cont rols o r timin gs duri ng th ese oper
ations. Table 17 on page 38 shows the address and data requirements for the chip erase
command sequence.
Any commands written to the chip during the Embedded Erase algorithm are ignored. Note that
a hardware reset during the chip erase operation immediately terminates the operation. The
Chip Erase command sequence should be reinitiated once the device has returned to reading
array data, to ensure dat a i nt egrity.

Sector Erase Command Sequence
Sector erase is a six bus cycle oper ation. The sector er ase command sequence is initiated by writing two unlock cycles, foll owed by a set-up command. Two additional unlock write cycles are then
followed by the address of the sector to be erased, and the sector erase command.
page 38 shows the address and data requirements for the sector erase command sequence.
The device does not requi re the system to preprogram the memory prio r to erase. The Embedded
Erase algorithm automatically programs and verifies the 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 command sequence is written, a sector erase time-out of 50 µs begins. During the timeout period, additional sector addresses and sector erase commands 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 50 µs, otherwise
the last address and command might not be accepted, and er asure may begin. It is recommended
that processor interrupts be disabled durin g this time to ensure al l commands are accepted. The
interrupts can be re-enabled aft er t he last Sector E ras e command is writ ten. If the time between
additional sector erase commands can be assumed to be less than 50 µs, the system need not
monitor DQ3. Any command other than Sector Erase or Erase Suspend during the time-out period resets the device to reading array data. T he syst em must rewrite the command
sequence and any additional sector addresses and commands.
The system can monitor DQ3 to determine if the sec tor erase timer has timed out . (See the “DQ3:
Sector Er as e Tim er” sec tion .) The time-out begins from the risin g edge of the final WE# pulse in
the command sequenc e .
Table 17 on
Once the sector erase operation has begun, only the Erase Suspend command is valid. All other
commands are ignored. Note that a hard ware rese t during the sector erase operation immedi
ately terminates the operation. The Sector Erase command sequence should be reinitiated once
the device has returned to reading a rray data, to ensure data integrity.
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
using DQ7, DQ6, DQ2, or RY/BY#. (Refer to
status bits.)
Figure 5, on page 36 illustrates the algorithm for the erase operation. Refer to Erase/Program
Operations on page 54 f or pa rameters, and to Figure 19, on page 56 for timing diagrams.
“Write Operation Status” for information on these
Erase Suspend/Erase Resume Commands
The Erase Suspend command allows the system to interrupt a sector erase operation and then
read data from, or program data to, any sector no t select ed for erasure . This comm and is valid
only during the sector erase oper ation, including the 50 µs time-out period duri ng the sector erase
command sequence. The Erase Suspend command is ignor ed if written durin g the chip erase op
eration or Embedded Program algorithm. Wri ting the E r ase Suspend c ommand duri ng th e Sector
Erase time-out immediately terminates the time-out period and suspends the erase operation.
Addresses ar e don’t-cares when writing the Erase Suspend command.
When the Erase Suspend command is writt en during a sector er ase operation, the device requires
a maximum of 20 µs to suspend the erase operation. Howev er , when t he Erase Suspend command
is written during the sector erase time-out, the device immediately terminates the time-out pe
riod and suspends the erase oper ation.

After the erase operation has been suspended, the system can read array data from or program
data to any sector not selected for erasure. (The device erase suspends all sectors selected for
erasure.) Normal read and write timings and command definitions apply . Reading at any address

within erase-suspended sectors produces st atus data on D Q7–DQ0. The system can u se DQ7, or
DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. See
Write Operation Status on page 39 for infor mation on the se status bits .
After an erase-suspended program operation is complete, the system can once ag ai n rea d array
data within non -suspended sectors. The system can determine the status of the pr ogram opera
tion using the DQ7 or DQ6 status bits, just as in the standard program operation. See Write
Operation Status on page 39 for more information.
The system may also write the autoselect command sequence when the device is in the Erase
Suspend mode. The device allows reading autoselect codes even at addresses within erasing sec
tors, since the codes are not stored in the memory array. When the device exits the autoselect
mode, the device reverts to the Erase Suspend mode, and is ready for another valid operation.

See
The system must write the Erase R esume command (address bits are don’ t care) to exit the erase
suspend mode and continue the sector erase operation. Further writes of the Resume command
are ignored. Another Erase Suspend command can be written after the device has resumed
erasing.

Write Operation Status
The device provides several bits to determine the status of a write operation: DQ2, DQ3, DQ5,
DQ6, DQ7, and RY/BY#.
of these bits. DQ7, RY/B Y#, an d DQ6 each of fer a metho d for determin in g wheth er a progr a m or
erase operation is complete o r in progress. These three bits are discussed first.
Table 18 on page 44 and the following subsections describe the functions
DQ7: Data# Polling
The Data# Polling bit, DQ 7, indicates to the host syste m whether an Embedde d Algorithm is in
progress or completed, or whether th e device is in Er ase Suspend. Data# P olling is v alid after t he
rising edge of the final WE# pulse in the program or erase command sequence.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the
datum programmed to DQ7. This DQ7 status als o applies to progr amming during E rase Suspend.
When the Embedded Program algorithm is comple te, the devic e output s the datum progr ammed
to DQ7. The system must provide the progr a m address to read valid status information on DQ7.
If a program address falls within a protected sector, Data# Polling on DQ7 is active for approxi
mately 1 µs, then the device returns to reading array data.
During the Embedded Erase algorithm, Data# P olli ng produc es a 0 o n DQ7. When the Embedded
Erase algorithm is complete, o r if the device enters the Er ase Suspend mode, Data# Polli ng pr o
duces a 1 on DQ7. This is analogous to the complement/true datum output described for the
Embedded Program algorithm: the erase function changes all the bits in a sector to 1; prior to
this, the device outputs the complement, or 0. The system must provide an address within any
of the sectors selected for erasure to read valid status information on DQ7.
After an erase command sequence is written, if all sectors selected for erasing are protected,
Data# Polling on DQ7 is acti ve for approxi mately 100 µs, then the device return s to reading arra y
data. If not all selected sectors are protected, the Embedded Erase algorithm erases the unpro
tected sectors, and ignores the selected sectors that are protected.
When the syst e m d e tects DQ7 has chan g e d from the comple m e nt to tr ue d a t a, i t ca n read valid
data at DQ7–DQ0 on th e following read cycles. This is because DQ7 may change asynchronously
with DQ0–DQ6 while Output Enable (OE#) is asserted low.
Timings (During Embedded Algorithms), in the AC Characteristics on page 50 section illustrates
this.

If the output is low (Busy), the device is actively er asing or progr amming. (This incl udes programming in the Erase Suspend mode.) If the output is high (Ready), the device is ready to read array
data (including during the Erase Suspend mode), or is in the standby mode.
Table 18 on page 44 shows the outputs for RY/B Y#. Fi gures Figure 14, o n page 50, Figure 15, on
page 51, Figure 18, on page 55 and Figure 19, on page 56 shows RY/BY# for read, reset, pro-
gram, and erase operations, respectively.
DQ6: Toggle Bit I
T ogg le Bit I on DQ6 indi cates whether an Embedded Progr am or Er ase algo rithm i s in progr ess or
complete, or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read
at any address, and is v alid after the risin g edge of the final WE# pulse i n 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 re ad cycles.)
When the operation is complete, DQ6 stops toggl ing.
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 algorithm erases the unprotected sectors, and ignores the
selected sectors that are protecte d.
The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or
is erase-suspended. 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 tog
gling. However, the system must also use DQ2 to determine which sectors are erasing or erasesuspended. Alternatively , the system can use DQ7 (see the subsection on
page 39).
If a program address falls within a pro tected sect or, DQ6 toggles for approximately 1 µs aft er 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 th e Embedded Program algorithm is complete.
Table 18 on page 44 shows the outputs fo r Toggle Bit I on DQ6. Figure 7, on page 43 shows the
toggle bit algorithm in flowchart form, and the sect ion Rea ding Toggle Bits DQ6/DQ2 on page 42
explains the algorithm. Figure 22, on page 57 shows the toggle bit timing diagrams. Figure 23,

tion on DQ2: To ggle Bit II.

DQ7: Data# Pol ling on
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 erasesuspended. 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 have been selected
for erasure. (The system may us e either OE# or CE# to cont rol the read cy cles.) But DQ2 cannot
distinguish whether the sector is actively er asing or is er ase-suspended. DQ6, by comparison, in
dicates whether the device is act ively 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
Figure 7, on page 43 shows the toggle bit algorithm in flowchart form, and the section Reading

the differences between DQ2 and DQ6 in graphical f orm.
Reading Toggle Bits DQ6/DQ2
Refer to Figure 7, on page 43 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 has 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 i s still tog gling, the system also s hould 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 successfully completed the progr am or erase operation. If it is still toggling, the devi ce
did not complete the operation successfully, and the system must write the reset command to
return to readi ng a r ray data .
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 suc
cessive read cycle s, determining the status as descr ibed in t he previou s para grap h. Alternativ ely,
it may choose to perform other system tasks. In this case, the system must start at the beginning
of the algorithm when it ret urns to determine the st atus of the oper ation (top of
43).

DQ5: Exceeded Timing Limits
DQ5 indicates whether the program or erase time has exceeded a specified internal pulse count
limit. Under these conditions DQ5 produces a 1. Thi s is a failure c ondition that indicates the pro
gram or erase cycle was not successfully completed.
The DQ5 failure condition may appear if the system tries to progr am a 1 to a location that is pre-
viously programmed to 0. Only an erase operation can change a 0 back to a 1. Under this

DQ5 produces a 1.
Under both these conditions, the system must issue the reset command to return the device to
reading array data.
DQ3: Sector Erase Timer
After writing a sector er ase command sequence, t he system may read D Q3 to determine whether
or not an erase operation has begun. (The sector erase timer does not apply to the chip erase
command.) If additional se ctors are selected fo r erasure, the entire time-out also applies after
each additional sector erase command. When the time-out is complete, DQ3 switches from 0 to
1. The system may ignore DQ3 if the system can guarantee that the time between additional
sector erase commands will always be less than 50 μs. See also the
Sequence on page 35 section.
After the sector erase command sequence is written, the system should read the status on DQ7
(Data# Polling) or DQ6 (Toggle Bit I) to ensure the device has accepted the command sequence,
and then read DQ3. If DQ3 is 1, the internally controlled erase cycle has begun; all further com
mands (other than Erase Suspend) are ignore d until the er ase operation is complete. I f DQ3 is 0,
the device will accept additional sector erase commands. To ensure the command has been ac
cepted, the system software shou ld check the status of DQ3 prior to and follow ing each
subsequent sector erase command. If DQ3 is high on the second status check, the last c ommand
might not have been accepted.

(Note 3)
Notes:
1. Typical program and erase times assume the following conditions: 25°C, V
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 17 for further information on command definitions.
6. The device has a minimum erase and program cycle endurance of 100,000 cycles per sector.
