S29AL004D
General Description
The S29AL004D is a 4 Mbit, 3.0 volt-only Flash memory organized as 524,288 bytes or 262,144 words. The device is offered in 48-
ball FBGA, 44-pin SO, and 48-pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data
appears on DQ7–DQ0. This device requires only a single, 3.0 volt VCC supply to perform read, program, and erase operations. A
standard EPROM programmer can also be used to program and erase the device.
This device is manufaSpansion’s 200 nm process technology, and offers all the features and benefits of the
Am29LV400B and BC, which were manufactured using 320 nm process technology.
The standard times of 70 and 90 ns, allowing high speed microprocessors to operate without wait states. To
eliminate bue has sarate chip enable (CE#), write enable (WE#) and output enable (OE#) controls.
The devicle 3.0 er supply for both read and write functions. Internally generated and regulated
voltages aprogroperations.
The device mmanwith the JEDEC single-power-supply Flash standard. Commands are written to
the command register using ocessor write timings. Register contents serve as input to an internal state-machine
that controls the erase ancircuitry. es also internally latch addresses and data needed for the programming
and erase operations. of the dice is sir to reading from other Flash or EPROM devices.
Device programming octing the ram coand sequence. This initiates the Embedded Program algorithm—an
internal algorithm that autoly times the pam pue widths and verifies proper cell margin. The Unlock Bypass mode
facilitates faster programming times bequiring y two write cprogram data instead of four.
Device erasure occurs by executing erase comand stiates the Embedded Erase algorithm—an internal
algorithm that automatically preprogs the ar(if it ammed) before executing the erase operation. During
erase, the device automatically times tpulse roper cell margin.
The host system can detect whether a program or mplete observing the RY/BY# pin, or by reading the DQ7
(Data# Polling) and DQ6 (toggle) status bits. Aftee cyclcompleted, the device is ready to read array data or
accept another command.
The sector erase architecture allows memory secterased d reprogrammed wt 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 detecthat automatically hibits write ations during power
transitions. The hardware sector protection feature disables program and operations in ancombination of the sectors
of memory. This can be achieved in-system or via programming ment.
The Erase Suspend feature enables the user to put erase on hold for any eriod of time read data frorogram data to, any
sector that is not selected for erasure. True background erase can thus chieved.
The hardware RESET# pin terminates any operation in progress and resetinternal state macne to reading y data. The
RESET# pin may be tied to the system reset circuitry. A system reset would thlso reset the vice, enabling e m
microprocessor to read the boot-up firmware from the Flash memory.
The device offers two power-saving features. When addresses are stable for a specified ount of time, evice enters he
automatic sleep mode. The system can also place the device into the standby mode. Power consumon reatly reduced in
both these modes.
Spansion’s Flash technology combines years of Flash memory manufacturing experience to proe the highest levels of quality,
reliability and cost effectiveness. The device electrically erases all bits within a sector simultasly via Fowler-Nordheim
tunneling. The data is programmed using hot electron injection.

7. Device Bus Operations
This section describes the requirements and use of the device bus operations, which are initiated through the internal command
register. The command register itself does not occupy any addressable memory location. The register is composed of latches that
store the commands, along with the address and data information needed to execute the command. The contents of the register
serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. Table 8 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 detai

Word/Byte Configuration
The BYTE# pin controls whether the device data I/O pins DQ15–DQ0 operate ihe byte or woconfigurationthe E# pin is
set at logic 1, the device is in word configuration, DQ15–DQ0 are active and controlled by Cand OE#.
If the BYTE# pin is set at logic 0, the device is in byte configuration, and only data I/O piDQ0–DQ7 are and controlled by
CE# and OE#. The data I/O pins DQ8–DQ14 are tri-stated, and the DQ15 pin is used as an input for thSB (address function.
8.2
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 r control and selects the
device. OE# is the output control and gates array data to the output pins. WE# should remain at VIH. ThBYTE# pin determines
whether the device outputs array data in words or bytes.
The internal state machine is set for reading array data upon 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 to obtain array
data. Standard microprocessor read cycles that assert valid addresses on the device address inputs produce valid data on the
device data outputs. The device remains enabled for read access until the command register contents are altered.

to Figure 23.1 on page 29 for the timing diagram. ICC1 in DC Characteristics on page 25 represents the active current specification
for reading array 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 WEo VIL, and OE# to VIH.

sector. The Command Dge 15 has aerasing a sector or the entire chip, or suspending/resuming the erase
operation.
After the system writes tt commanequenche device enters the autoselect mode. The system can then read
autoselect codes from the il regiser (whisepate from the memory array) on DQ7–DQ0. Standard read cycle timings
apply in this mode. Refer to AutoseleMode on e 12 and ACommand Sequence on page 16 for more information.

8.5
Standby Mode
When the system is not reading or writing to the device, it can plae devicn the dby mode. In mode, current
consumption is greatly reduced, and the outputs are placed in the high impance statedependent of E# input.
The device enters the CMOS standby mode when the CE# and RESET# are both held at VCC 0V. (Nothat this is a more
restricted voltage range than VIH.) If CE# and RESET# are held at VIH, but nthin VCC 0.3 V, thevice is in the andby mode,

8.6
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically ens this mode when
addresses remain stable for tACC + 30 ns. The automatic sleep mode is independent of the CE#, WE#, d OE# control signals.
Standard address access timings provide new data when addresses are changed. While in sleep mode, output data is latched and
always available to the system. ICC4 in DC Characteristics on page 25 represents the automatic sleep mode current specification.

8.7
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading array data. When the RESET# pin is driven low for
at least a period of tRP, the device immediately terminates any operation in progress, tristates all output pins, and ignores all read/
write commands for the duration of the RESET# pulse. The device also resets the internal state machine to reading array data. The
operation that was interrupted should be reinitiated once the device is ready to accept another command sequence, to ensure data
integrity.
Current is reduced for tn of the RESET# pulse. When RESET# is held at VSS±0.3 V, the device draws CMOS standby
current (ICC4). If REVIL but not within VSS±0.3 V, the standby current is greater.
The RESET# psystem reset circuitry. A system reset would thus also reset the Flash memory, enabling the
system to rere from he Flash memory.
If RESET# prograse operation, the RY/BY# pin remains a 0 (busy) until the internal reset operation is
complete, me of tg Embedded Algorithms). The system can thus monitor RY/BY# to determine
whether tn is coT# is asserted when a program or erase operation is not executing (RY/BY# pin is
1), the reseis come of tREADY (not during Embedded Algorithms). The system can read data tRH after
the RESET# pin returns to

11.1 Sector Protection/Unprotection
The hardware sector protection feature disables both program and erase operations in any sector. The hardware sector unprotection
feature re-enables both program and erase operations in previously protected sectors.
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 Spansion’s ExpressFlash™ Service. Contact an Spansion representative for details.
It is possible to determine whether a sector is protected or unprotected. See Autoselect Mode on page 12 for details.
Document Number: 002-01235 Rev. *B
Page 12 of 46
S29AL004D
Sector Protection/unprotection can be implemented via two methods.
The primary method requires VID on the RESET# pin only, and can be implemented either in-system or via programming equipment.
Figure 11.2 on page 14 shows the algorithms and Figure 26.2 on page 36 shows the timing diagram. This method uses standard
microprocessor bus cycle timing. For sector unprotect, all unprotected sectors must first be protected prior to the first sector
unprotect write cycle.
The alternate method intended only for programming equipment requires VID on address pin A9 and OE#. This method is
compatible with programnes written for earlier 3.0 volt-only Spansion flash devices.
11.2 Teor Unprotect
This feature protectif previously protected sectors to change data in-system. The Sector Unprotect mode is
activated b# pin ting this mode, formerly protected sectors can be programmed or erased by selecting
the sector VID is the RESET# pin, all the previously protected sectors are protected again.

11.3 Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing provides data protection against inadvertent
writes (refer to Table 12.2 on page 19 for command definitions). In addition, the following hardware data protection measures
prevent accidental erasure or programming, which might otherwise be caused by spurious system level signals during VCC
power-up and power-down transitions, or from system noise.
11.3.1
Low te Inhibit
When VCC is less vice does not accept any write cycles. This protects data during VCC power-up and power-down.
The command nal program/erase circuits are disabled, and the device resets. Subsequent writes are ignored
until VCC is ge system must provide the proper signals to the control pins to prevent unintentional writes when
VCC is grea

All addresses are latched on the falling edge of WE# or CE#, wher happelatll data is latchn the rising edge of WE#
or CE#, whichever happens first. Refer to the appropriate timing dims in C Charastics on page
12.1 Reading Array Data
The device is automatically set to reading array data after device power-up. No mands are ruired to retriedahe device
is also ready to read array data after completing an Embedded Program or Embedded Erase gorithm.
After the device accepts an Erase Suspend command, the device enters the Erase Suspmode. The sm can read array data
using the standard read timings, except that if it reads at an address within erase-suspended sectors, thdevutputs status data.
After completing a programming operation in the Erase Suspend mode, the system may once again ad array with the same
exception. See Erase Suspend/Erase Resume Commands on page 18 for more information on tmode.
The system must issue the reset command to re-enable the device for reading array data if DQ5 gogh, or while in the autoselect
mode. See Reset Command on page 15.
See also Requirements for Reading Array Data on page 9 for more information. The Read Operations on page 29 provides the read
parameters, and Figure 23.1 on page 29 shows the timing diagram.
12.2 Reset Command
Writing the reset command to the device resets the device to reading array data. Address bits are don’t care for this command.
Document Number: 002-01235 Rev. *B
Page 15 of 46
S29AL004D
The reset command may be written between the sequence cycles in an erase command sequence before erasing begins. This
resets the device to reading array data. Once erasure begins, however, the device ignores reset commands until the operation is
complete.
The reset command may be written between the sequence cycles in a program command sequence before programming begins.
This resets the device to reading array data (also applies to programming in Erase Suspend mode). Once programming begins,
however, the device ignores reset commands until the operation is complete.
The reset command maen between the sequence cycles in an autoselect command sequence. Once in the autoselect
mode, the reset cowritten to return to reading array data (also applies to autoselect during Erase Suspend).
If DQ5 goes hior erase operation, writing the reset command returns the device to reading array data (also

12.3 Comquence
The autosed sequost system to access the manufacturer and devices codes, and determine whether
or not a sector is protected. ge 19 shows the address and data requirements. This method is an alternative to that
shown in Table 11 on paintended fPprogrammers and requires VID on address bit A9.
The autoselect commnitiated writing tunlock cycles, followed by the autoselect command. The device then
enters the autoselect msystem mead at aaddress any number of times, without initiating another command
sequence.
A read cycle at address XX00h retries the mancturer codcle at address XX01h in word mode (or 02h in byte mode)
returns the device code. A read cycontaining ector the address 02h in word mode (or 04h in byte mode)
returns 01h if that sector is protected00h if iunpble 9 on page 11 and Table 10 on page 11 for valid
sector addresses.
The system must write the reset command to exit tnd retto reading array data.
12.4 Word/Byte Program Comquene
The system may program the device by word or byte, depending ohe state of the BY# programming is a four-bus-cycle
operation. The program command sequence is initiated by writitwo unlock write cys, followy the program set-up
command. The program address and data are written next, win turn initiate thmbedded Prram algorithm. The system is
not required to provide further controls or timings. The device aatically proeernally generatprogram pulses and
verifies the programmed cell margin. Table 12.2 on page 19 showaddrand dequirements fe byte program
command sequence.
When the Embedded Program algorithm is complete, the device then retto reading array data anaddress are no longer
latched. The system can determine the status of the program operation by uDQ7, DQ6, or RY/#. See Write ration Status
on page 20 for information on these status bits.
Any commands written to the device during the Embedded Program Algorithm are ignored. Ne that a harde reset idiately
terminates the programming operation. The program command sequence should be reinied once the de has reset to reading
array data, to ensure data integrity.
Programming is allowed in any sequence and across sector boundaries. A bit cannot be programed from a ack to a 1.
Attempting to do so may halt the operation and set DQ5 to 1, or cause the Data# Polling algoritho indicate the operation was
successful. However, a succeeding read shows that the data is still 0. Only erase operations can ert a 0 to a 1.
12.4.1
Unlock Bypass Command Sequence
The unlock bypass feature allows the system to program bytes or words to the device faster than using the standard program
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. The device then enters the unlock bypass mode. A two-cycle unlock
bypass 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 total programming time. Table 12.2 on page 19 shows the requirements for the command sequence.
Document Number: 002-01235 Rev. *B
Page 16 of 46
S29AL004D
During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are valid. To exit the unlock
bypass mode, the system must issue the two-cycle unlock bypass reset command sequence. The first cycle must contain the data
90h; the second cycle the data 00h (F0h). Addresses are don’t care for both cycles. The device then returns to reading array data.
Figure 12.1 illustrates the algorithm for the program operation. See Table 25 on page 30 for parameters, and Figure 25.3

12.5 Chip Erase Command Sequence
Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by ting two unlocycles, followby a
set-up command. Two additional unlock write cycles are then followed by the chip erase mmand, whicrn invokes the
Embedded Erase algorithm. The device does not require the system to preprogram prior to erase. ThmbeErase algorithm
automatically preprograms and verifies the entire memory for an all zero data pattern prior to electrl erase. Tystem is not
required to provide any controls or timings during these operations. Table 12.2 on page 19 showe 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 harre reset during the chip
erase operation immediately terminates the operation. The Chip Erase command sequence should be renitiated once the device
has returned to reading array data, to ensure data integrity.
The system can determine the status of the erase operation by using DQ7, DQ6, DQ2, or RY/BY#. See Write Operation Status
on page 20 for information on these status bits. When the Embedded Erase algorithm is complete, the device returns to reading
array data and addresses are no longer latched.
Figure 12.2 on page 19 illustrates the algorithm for the erase operation. See Table 25 on page 30 for parameters and Figure 25.4
on page 33 for timing diagrams.
Document Number: 002-01235 Rev. *B
Page 17 of 46
S29AL004D
12.6 Sector Erase Command Sequence
Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two unlock cycles, followed by
a set-up command. Two additional unlock write cycles are then followed by the address of the sector to be erased, and the sector
erase command. Table 12.2 on page 19 shows the address and data requirements for the sector erase command sequence.
The device does not require the system to preprogram the memory prior 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 duriperations.
After the commanten, a sector erase time-out of 50 µs begins. During the time-out period, additional sector
addresses and nds may be written. Loading the sector erase buffer may be done in any sequence, and the
number of see sector to all sectors. The time between these additional cycles must be less than 50 µs,
otherwise tommanht not be accepted, and erasure may begin. It is recommended that processor
interrupts is timall commands are accepted. The interrupts can be re-enabled after the last Sector
Erase comthe tiditional sector erase commands can be assumed to be less than 50 µs, the system
need not mAny coan Sector Erase or Erase Suspend during the time-out period resets the
device to reaarray daust rewrite the command sequence and any additional sector addresses and
commands.
The system can moniine if thector eratimer has timed out. (See DQ3: Sector Erase Timer on page 23). The
time-out begins from thf the finaE# pulse the command sequence.
Once the sector erase operahas bun, one Erase Suspend command is valid. All other commands are ignored. Note that
a hardware reset during the sector ese operaimmediatees the operation. The Sector Erase command sequence
should be reinitiated once the devicas returneo readiensure data integrity.
When the Embedded Erase algorithcomple, the ding array data and addresses are no longer latched.
The system can determine the status of rase o, DQ6, Q2, or RY/BY#. Refer to Write Operation Status
on page 20 for information on these status bits.
Figure 12.2 on page 19 illustrates the algorithm fon. Reto Table 25 on page 30 for parameters, and to
Figure 25.4 on page 33 for timing diagrams.
12.7 Erase Suspend/Erase Resume Comands
The Erase Suspend command allows the system to interrupt tor erase operand then read data from, or program data to,
any sector not selected for erasure. This command is valid only g the secerperation, inclg the 50 µs time-out
period during the sector erase command sequence. The Erase Susnd coand is ied if written dthe chip erase
operation or Embedded Program algorithm. Writing the Erase Suspend cmand during he Sector Erasout immediately
terminates the time-out period and suspends the erase operation. Addreare don’t-cares when wrg the se Suspend
command.
When the Erase Suspend command is written during a sector erase operation, device requis a maximum 20 suspend
the erase operation. However, when the Erase Suspend command is written during the secterase time-ouhe devic
immediately terminates the time-out period and suspends the erase operation.
After the erase operation is suspended, the system can read array data from or program data to any seor nected for erasure.
(The device erase suspends all sectors selected for erasure.) Normal read and write timings and comand defins apply.
Reading at any address within erase-suspended sectors produces status data on DQ7–DQ0. Thstem can use DQ7, or DQ6 and
DQ2 together, to determine if a sector is actively erasing or is erase-suspended. See Write OperaStatus on page 20 for
information on these status bits.
After an erase-suspended program operation is complete, the system can once again read array data whin non-suspended
sectors. The system can determine the status of the program operation using the DQ7 or DQ6 status bits, just as in the standard
program operation. See Write Operation Status on page 20 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 sectors, 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
Autoselect Command Sequence on page 16 for more information.
Document Number: 002-01235 Rev. *B
Page 18 of 46
S29AL004D
The system must write the Erase Resume 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.

14. Write Operation Status
The device provides several bits to determine the status of a write oeratioDQ2, DQ3Q5, DQ6, DQ7RY/BY#. Table 15
on page 24 and the following subsections describe the functions of thess. DQ7, RY/BY#, and DQ6 ch a method for
determining whether a program or erase operation is complete or in progrThese three bits are dussed first.
14.1 DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Algoriths in progress mpleted, or whether
the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final WE# pulse in the ogor erase command
sequence.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the daprogrammed to DQ7. This DQ7
status also applies to programming during Erase Suspend. When the Embedded Program algorithcomplete, the device outputs
the datum programmed to DQ7. The system must provide the program address to read valid status inftion on DQ7. If a program
address falls within a protected sector, Data# Polling on DQ7 is active for approximately 1 µs, then the vice returns to reading
array data.
During the Embedded Erase algorithm, Data# Polling produces a 0 on DQ7. When the Embedded Erase algorithm is complete, or if
the device enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7. 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.
Document Number: 002-01235 Rev. *B
Page 20 of 46
S29AL004D
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 device returns to reading array data. If not all selected sectors are protected, the Embedded Erase
algorithm erases the unprotected sectors, and ignores the selected sectors that are protected.
When the system detects DQ7 has changed from the complement to true data, it can read valid data at DQ7–DQ0 on the following
read cycles. This is because DQ7 may change asynchronously with DQ0–DQ6 while Output Enable (OE#) is asserted low.
Figure 25.6 on page 34 illustrates this.
Table 15 on page 24 shutputs for Data# Polling on DQ7. Figure 14.1 on page 21 shows the Data# Polling algorithm.

Notes
1. VA = Valid address for programming. During a sector erase operation, a valid address is an address within any sectlected for erasururing che, a valid
address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 = 1 because DQ7 may change simultaneously with DQ5.
14.2 RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin that indicates whether an Embedded Algorithm progress or complete. The
RY/BY# status is valid after the rising edge of the final WE# pulse in the command sequence. Since R# is an open-drain output,
several RY/BY# pins can be tied together in parallel with a pull-up resistor to VCC
.
If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the Erase Suspend mode.)
If the output is high (Ready), the device is ready to read array data (including during the Erase Suspend mode), or is in the standby
mode.
Table 15 on page 24 shows the outputs for RY/BY#. Figure 23.1 on page 29, Figure 24.1 on page 30, Figure 25.3 on page 32, and
Figure 25.4 on page 33 shows RY/BY# for read, reset, program, and erase operations, respectively.

14.3 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 may be read at any address, and is valid after the rising edge of the final WE#
pulse in the command sequence (prior to the program or erase operation), and during the sector erase time-out.
During an Embedded Program or Erase algorithm operation, successive read cycles to any address cause DQ6 to toggle. (The
system may use either OE# or CE# to control the read cycles.) When the operation is complete, DQ6 stops toggling.
After an erase commis written, if all sectors selected for erasing are protected, DQ6 toggles for approximately 100 µs,
then returns to renot all selected sectors are protected, the Embedded Erase algorithm erases the unprotected
sectors, and igectors that are protected.
The system 2 togetto determine whether a sector is actively erasing or is erase-suspended. When the
device is as, the d Erase algorithm is in progress), DQ6 toggles. When the device enters the Erase
Suspend gglinge system must also use DQ2 to determine which sectors are erasing or erase-
suspendehe sys7 (see DQ7: Data# Polling on page 20).
If a program ass falls wiector, DQ6 toggles for approximately 1 µs after the program command sequence is
written, then returns to re.
DQ6 also toggles duriend-proam modnd stops toggling once the Embedded Program algorithm is complete.
Table 15 on page 24 shouts for ToBit I on Q6. Figure 14.2 on page 23 shows the toggle bit algorithm. Figure 25.7
on page 34 shows the toggltiming agramgure 25.8 on page 34 shows the differences between DQ2 and DQ6 in graphical
form. See also DQ2: Toggle Bit II on ge 22.
14.4 DQ2: Toggle Bit I
The Toggle Bit II on DQ2, when used with DQ6, indcular stor is actively erasing (that is, the Embedded
Erase algorithm is in progress), or whether that seed. Tle 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 sectorat are selected for asure. (The system may use either
OE# or CE# to control the read cycles.) But DQ2 cannot distinguish hether the sector icerasing or is erase-suspended.
DQ6, by comparison, indicates whether the device is actively erag, or is in Erase Spend, annot distinguish which sectors
are selected for erasure. Thus, both status bits are required foctor and mode inmation. RefeTable 15 on page 24 to
compare outputs for DQ2 and DQ6.
Figure 14.2 on page 23 shows the toggle bit algorithm in flowchart , and e sectio2: Toggle Bit page 22 explains the
algorithm. See also the DQ6: Toggle Bit I on page 22 subsection. Figure 7 on page 34 shows the toggming diagram.
Figure 25.8 on page 34 shows the differences between DQ2 and DQ6 in phical form.
14.5 Reading Toggle Bits DQ6/DQ2
Refer to Figure 14.2 on page 23 for the following discussion. Whenever the system initially egins reading gle bit statumust
read DQ7–DQ0 at least twice in a row to determine whether a toggle bit is toggling. Typlly, the systenote and store the
value of the toggle bit after the first read. After the second read, the system would compare the new vue of tggle bit with the
first. If the toggle bit is not toggling, the device has completed the program or erase operation. The stem can rarray data on
DQ7–DQ0 on the following read cycle.
However, if after the initial two read cycles, the system determines that the toggle bit is still togglingsystem also should note
whether the value of DQ5 is high (see DQ5: Exceeded Timing Limits on page 23). If it is, the system sd 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 program or erase operation. If it is still toggling, the device did not completed the
operation successfully, and the system must write the reset command to return to reading array data.
The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not gone high. The system
may continue to monitor the toggle bit and DQ5 through successive read cycles, determining the status as described in the previous
paragraph. Alternatively, it may choose to perform other system tasks. In this case, the system must start at the beginning of the
algorithm when it returns to determine the status of the operation (top of Figure 14.2 on page 23)

S29AL004D
14.6 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. This is a failure condition that indicates the program or erase cycle was not successfully completed.
The DQ5 failure condition may appear if the system tries to program a 1 to a location that is previously programmed to 0. Only an
erase operation can change a 0 back to a 1. Under this condition, the device halts the operation, and when the operation has
exceeded the timing limits, DQ5 produces a 1.
Under both these conystem must issue the reset command to return the device to reading array data.
14.7 Dase Timer
After writinmand ce, the system may read DQ3 to determine whether or not an erase operation has
begun. (Tr does the chip erase command.) If additional sectors are selected for erasure, the entire
time-out aeach aerase command. When the time-out is complete, DQ3 switches from 0 to 1. The
system ma3 if the antee that the time between additional sector erase commands is always less than
50 µs. See also the Sector Sequence on page 18.

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 commands (other than Erase Suspend) are ignored until the erase operation is complete. If DQ3 is 0, the
device accepts additional sector erase commands. To ensure the command is accepted, the system software should check the
status of DQ3 prior to and following each subsequent sector erase command. If DQ3 is high on the second status check, the last
command might not have been accepted. Table 15 shows the outputs for DQ3.

Notes
1. Typical program and erase times assume the following conditions: 25C, V = 3.0 V, 100,000 cycles, checkerboard datern.
CC
2. Under worst case conditions of 90°C, V = 2.7 V, 1,000,000 cycles.
CC
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes proaster 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 on page 19 for further information
on command definitions.
6. The device has a minimum erase and program cycle endurance of 100,000 cycles per sector
