General Description
The S29AL016J is a 16 Mbit, 3.0 Volt-only Flash memory organized as 2,097,152 bytes or 1,048,576 words.
The device is offered in 48-ball Fine-pitch BGA (0.8 mm pitch), 64-ball Fortified BGA (1.0 mm pitch) and 48pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on
DQ7–DQ0. This device is designed to be programmed in-system with the standard system 3.0 volt VCC
supply. A 12.0 V VPP or 5.0 VCC are not required for write or erase operations. The device can also be
programmed in standard EPROM programmers.
The device offers access time of 55 ns allowing high speed microprocessors to operate without wait states. To
eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable
(OE#) controls.
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 program and erase operations.
The S29AL016J is entirely command set compatible with the JEDEC single-power-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 programming circuitry. Write
cycles also internally latch addresses and data 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 occurs by executing the program command sequence. This initiates the Embedded
Program algorithm—an internal algorithm that automatically times the program pulse widths and verifies
proper cell margin. The Unlock Bypass mode facilitates faster programming times by requiring only two write
cycles to program data instead of four.
Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase
algorithm—an internal algorithm that automatically preprograms the array (if it is not already programmed)
before executing the erase operation. During erase, the device automatically times the erase pulse widths
and verifies proper 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. After a program or erase cycle has been
completed, the device 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 automatically inhibits write operations
during power transitions. The hardware sector protection feature disables both program and erase
operations in any combination of the sectors of memory. This can be achieved in-system or via programming
equipment.
The Erase Suspend/Erase Resume feature enables the user to put erase on hold for any period of time to
read data from, or program data to, any sector that is not selected 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 to the system reset circuitry. A system reset would thus also
reset the device, enabling 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 device enters the automatic sleep mode. The system can also place the device into the standby
mode. Power consumption is greatly reduced in both these modes.
Spansion combines years of flash memory manufacturing experience to produce the highest levels of quality,
reliability and cost effectiveness. The device electrically erases all bits within a sector simultaneously via
Fowler-Nordheim tunneling. The data is programmed using hot electron injection.

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 7.1 lists the device bus operations, the
inputs and control levels they require, and the resulting output. The following subsections describe each of
these operations in further detail.

Notes
1. Address In = Amax:A0 in WORD mode (BYTE#=VIH), Address In = Amax:A-1 in BYTE mode (BYTE#=VIL). Sector addresses are Amax
to A12 in both WORD mode and BYTE mode.
2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See Section 7.10, Sector Group
Protection/Unprotection on page 20.
3. If WP# = VIL, the outermost sector remains protected (determined by device configuration). If WP# = VIH, the outermost sector protection
depends on whether the sector was last protected or unprotected using the method described in Section 7.10, Sector Group Protection/
Unprotection on page 20. The WP# contains an internal pull-up; when unconnected, WP is at VIH.
4. DIN or DOUT as required by command sequence, data polling, or sector group protection algorithm.
7.1
Word/Byte Configuration
The BYTE# pin controls whether the device data I/O pins DQ15–DQ0 operate in the byte or word
configuration. If the BYTE# pin is set at logic 1, the device is in word configuration, DQ15–DQ0 are active and
controlled by CE# and OE#.
If the BYTE# pin is set at logic 0, the device is in byte configuration, and only data I/O pins DQ0–DQ7 are
active and controlled by CE# and OE#. The data I/O pins DQ8–DQ14 are tri-stated, and the DQ15 pin is used
as an input for the LSB (A-1) address function.
7.2
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 power
control and selects the device. OE# is the output control and gates array data to the output pins. WE# should
remain at VIH. The BYTE# 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
April 12, 2012 S29AL016J_00_12
S29AL016J

S hee t
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.
See Reading Array Data on page 29 for more information. Refer to the AC Read Operations on page 43 for
timing specifications and to Figure 17.1 on page 43 for the timing diagram. ICC1 in DC Characteristics
on page 41 represents the active current specification for reading array data.
7.3
Writing Commands/Command Sequences
To write a command or command sequence (which includes programming data to the device and erasing
sectors of memory), the system must drive WE# and CE# to VIL, and OE# to VIH.
For program operations, the BYTE# pin determines whether the device accepts program data in bytes or
words. See Word/Byte Configuration on page 15 for more information.
The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the
Unlock Bypass mode, only two write cycles are required to program a word or byte, instead of four. Word/
Byte Program Command Sequence on page 30 has details on programming data to the device using both
standard and Unlock Bypass command sequences.
An erase operation can erase one sector, multiple sectors, or the entire device. Table 7.2 on page 18 and
Table 7.4 on page 19 indicate the address space that each sector occupies. A “sector address” consists of
the address bits required to uniquely select a sector. The Command Definitions on page 29 has details on
erasing a sector or the entire chip, or suspending/resuming the erase operation.
After the system writes the autoselect command sequence, the device enters the autoselect mode. The
system can then read autoselect codes from the internal register (which is separate from the memory array)
on DQ7–DQ0. Standard read cycle timings apply in this mode. Refer to Autoselect Mode on page 20 and
Autoselect Command Sequence on page 29 for more information.
ICC2 in DC Characteristics on page 41 represents the active current specification for the write mode. AC
Characteristics on page 43 contains timing specification tables and timing diagrams for write operations.
7.4
Program and Erase Operation Status
During an erase or program operation, the system may check the status of the operation by reading the
status bits on DQ7–DQ0. Standard read cycle timings and ICC read specifications apply. Refer to Write
Operation Status on page 35 for more information, and to AC Characteristics on page 43 for timing diagrams.
7.5
Standby Mode
When the system is not reading or writing to the device, it can place the device 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 CMOS standby 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 current will be greater. 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 active current until the operation
is completed.
ICC3 and ICC4 represents the standby current specification shown in the table in DC Characteristics
on page 41.

Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enables
this mode when addresses remain stable for tACC + 30 ns. The automatic sleep mode is independent of the
CE#, WE#, and 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 the DC
Characteristics on page 41 represents the automatic sleep mode current specification.
7.7
RESET#: Hardware Reset Pin
The RESET# pin provides a hardware method of resetting the device to reading array data. When the system
drives the RESET# pin to VIL for at least a period of tRP, the device immediately terminates any operation in
progress, tristates all data output pins, and ignores all read/write attempts 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 the duration of the RESET# pulse. When RESET# is held at VSS ±0.3V, the device
draws CMOS standby current (ICC4). If RESET# is held at VIL but not within VSS ±0.3/0.1V, the standby
current will be greater.
The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the Flash
memory, enabling the system to read the boot-up firmware from the Flash memory. Note that the CE# pin
should only go to VIL after RESET# has gone to VIH. Keeping CE# at VIL from power up through the first read
could cause the first read to retrieve erroneous data.
If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a 0 (busy) until the
internal reset operation is complete, which requires 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 system can read data tRH after the
RESET# pin returns to VIH.
Refer to the tables in AC Characteristics on page 43 for RESET# parameters and to Figure 17.2 on page 44
for the timing diagram.
7.8
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 group protection
verification, through identifier codes output on DQ7–DQ0. This mode is primarily intended for programming
equipment to automatically match a device to be programmed with its corresponding programming algorithm.
However, the autoselect codes can also be accessed in-system through the command register.
When using programming equipment, the autoselect mode requires VID (8.5 V to 12.5 V) on address pin A9.
Address pins A6 and A3–A0 must be as shown in Table 7.6. In addition, when verifying sector group
protection, the sector address must appear on the appropriate highest order address bits (see Table 7.2
on page 18 and Table 7.4 on page 19). Table 7.6 shows the remaining address bits that are don’t care. When
all necessary bits have been set as required, the programming equipment may then read the corresponding
identifier code on DQ7-DQ0.
To access the autoselect codes in-system, the host system can issue the autoselect command via the
command register, as shown in Table 10.1 on page 34. This method does not require VID. See Command
Definitions on page 29 for details on using the autoselect mode.

Sector Group Protection/Unprotection
The hardware sector group protection feature disables both program and erase operations in any sector
group (see Table 7.2 on page 18 to Table 7.4 on page 19). The hardware sector group unprotection feature
re-enables both program and erase operations in previously protected sector groups. Sector group
protection/unprotection can be implemented via two methods.
Sector protection/unprotection requires VID on the RESET# pin only, and can be implemented either insystem or via programming equipment. Figure 7.2 on page 23 shows the algorithms and Figure 17.12
on page 50 shows the timing diagram. This method uses standard microprocessor bus cycle timing. For
sector group unprotect, all unprotected sector groups must first be protected prior to the first sector group
unprotect write cycle.
The device is shipped with all sector groups unprotected. Spansion offers the option of programming and
protecting sector groups at its factory prior to shipping the device through Spansion Programming Service.
Contact a Spansion representative for details.
It is possible to determine whether a sector group is protected or unprotected. See Autoselect Mode
on page 20 for details.

Temporary Sector Group Unprotect
This feature allows temporary unprotection of previously protected sector groups to change data in-system.
The Sector Group Unprotect mode is activated by setting the RESET# pin to VID. During this mode, formerly
protected sector groups can be programmed or erased by selecting the sector group addresses. Once VID is

8. Secured Silicon Sector Flash Memory Region
The Secured Silicon Sector feature provides a 256-byte Flash memory region that enables permanent part
identification through an Electronic Serial Number (ESN). The Secured Silicon Sector uses a Secured Silicon
Sector Indicator Bit (DQ7) to indicate whether or not the Secured Silicon 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.
Spansion offers the device with the Secured Silicon Sector either factory-locked or customer-lockable. 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 customerlockable version has the Secured Silicon Sector Indicator Bit permanently set to a 0. Thus, the Secured
Silicon Sector Indicator Bit prevents customer-lockable devices from being used to replace devices that are
factory locked.
The system accesses the Secured Silicon Sector through a command sequence (see Enter/Exit Secured
Silicon Sector Command Sequence on page 30). After the system writes the Enter Secured Silicon Sector
command sequence, it may read the Secured Silicon Sector by using the addresses normally occupied by the
boot sectors. This mode of operation 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 device reverts to sending commands to the boot sectors.
8.1
Factory Locked: Secured Silicon Sector Programmed
and Protected at the Factory
In a factory locked device, the Secured Silicon Sector is protected when the device is shipped from the
factory. The Secured Silicon Sector cannot be modified in any way. The device is available pre-programmed
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 byte mode (or 00000h–00007h in word mode). In the Top Boot device, the ESN is in
sector 34 at addresses 1FFFF0h–1FFFFFh in byte mode (or FFFF8h–FFFFFh in word mode).
Customers may opt to have their code programmed by Spansion through 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
representative for details on using the Spansion ExpressFlash service.
8.2
Customer Lockable: Secured Silicon Sector NOT Programmed
or Protected at the Factory
The customer lockable version allows the Secured Silicon Sector to be programmed once, and then
permanently locked after it ships from Spansion. Note that the unlock bypass functions is not available when
programming the Secured Silicon Sector.
The Secured Silicon Sector area can be protected using the following procedures:
 Write the three-cycle Enter Secured Silicon Region command sequence, and then follow the in-system
sector group protect algorithm as shown in Figure 7.2 on page 23, substituting the sector group address
with the Secured Silicon Sector group address (A0=0, A1=1, A2=0, A3=1, A4=1, A5=0, A6=0, A7=0). Note
that this method is only applicable to the Secured Silicon Sector.
 To verify the protect/unprotect status of the Secured Silicon Sector, follow the algorithm shown in Figure
8.1 on page 25.
Once the Secured Silicon Sector is locked and verified, the system must write the Exit Secured Silicon Sector
Region command sequence to return to reading and writing the remainder of the array.

The Secured Silicon Sector protection must be used with caution since, once protected, there is no procedure
available for unprotecting the Secured Silicon Sector area, and none of the bits in the Secured Silicon Sector

Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software interrogation
handshake, which allows specific vendor-specified software algorithms to be used for entire families of
devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and
backward-compatible for the specified flash device families. Flash vendors can standardize their existing
interfaces for long-term compatibility.
This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address
55h 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 Table 9.1 to Table 9.4 on page 27. In word mode, the
upper address bits (A7–MSB) must be all zeros. To terminate reading CFI data, the system must write the
reset command.
The system can also write the CFI query command when the device is in the autoselect mode. The device
enters the CFI query mode, and the system can read CFI data at the addresses given in Table 9.1 to
Table 9.4 on page 27. The system must write the reset command to return the device to the autoselect mode.

Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing provides data protection
against inadvertent writes (refer to Table 10.1 on page 34 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.
9.1.1
Low VCC Write Inhibit
When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC
power-up and power-down. The command register and all internal program/erase circuits are disabled, and
the device resets. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the
proper signals to the control pins to prevent unintentional writes when VCC is greater than VLKO.
9.1.2
Write Pulse Glitch Protection
Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.
9.1.3
Logical Inhibit
Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle,
CE# and WE# must be a logical zero while OE# is a logical one.
9.1.4
Power-Up Write Inhibit
If WE# = CE# = VIL and OE# = VIH during power up, the device does not accept commands on the rising
edge of WE#. The internal state machine is automatically reset to reading array data on power-up.

10. Command Definitions
Writing specific address and data commands or sequences into the command register initiates device
operations. Table 10.1 on page 34 defines the valid register command sequences. Writing incorrect
address and data values or writing them in the improper sequence resets the device to reading array data.
All addresses are latched on the falling edge of WE# or CE#, whichever happens later. All data is latched on
the rising edge of WE# or CE#, whichever happens first. Refer to the appropriate timing diagrams in AC
Characteristics on page 43.
10.1
Reading Array Data
The device is automatically set to reading array data after device power-up. No commands are required to
retrieve data. The device is also ready to read array data after completing an Embedded Program or
Embedded Erase algorithm.
After the device accepts an Erase Suspend command, the device enters the Erase Suspend mode. The
system can read array data using the standard read timings, except that if it reads at an address within erasesuspended 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 Erase Suspend/
Erase Resume Commands on page 32 for more information on this mode.
The system must issue the reset command to re-enable the device for reading array data if DQ5 goes high, or
while in the autoselect mode. See Reset Command on page 29.
See also Requirements for Reading Array Data on page 15 for more information. The Read Operations
on page 43 provides the read parameters, and Figure 17.1 on page 43 shows the timing diagram.
10.2
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.
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 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 reading 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).
10.3
Autoselect Command Sequence
The autoselect command sequence allows the host system to access the manufacturer and devices codes,
and determine whether or not a sector is protected. Table 10.1 on page 34 shows the address and data
requirements. This method is an alternative to that shown in Table 7.6 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 then enters the autoselect mode, and the system may read at any address any
number of times, without initiating another command sequence.
A read cycle at address XX00h retrieves the manufacturer code. A read cycle at address XX01h 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 Table 7.2 on page 18 and
Table 7.4 on page 19 for valid sector addresses.
The system must write the reset command to exit the autoselect mode and return to reading array data.

Enter/Exit Secured Silicon Sector Command Sequence
The Secured Silicon Sector region provides a secured data area containing a random, sixteen-byte electronic
serial number (ESN). The system can access the Secured Silicon Sector region by issuing the three-cycle
Enter Secured Silicon Sector command sequence. The device continues to access the Secured Silicon
Sector region until the system issues the four-cycle Exit Secured Silicon Sector command sequence. The Exit
Secured Silicon Sector command sequence returns the device to normal operation. Table 10.1 on page 34
shows the addresses and data requirements for both command sequences. Note that the unlock bypass
mode is not available when the device enters the Secured Silicon Sector. See also Secured Silicon Sector
Flash Memory Region on page 24 for further information.
10.5
Word/Byte 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 command sequence is initiated by writing two unlock write cycles,
followed by the program set-up command. The program address and data are written next, which in turn
initiate the Embedded Program algorithm. The system is not required to provide further controls or timings.
The device automatically generates the program pulses and verifies the programmed cell margin. Table 10.1
on page 34 shows the address and data requirements for the byte program command sequence.
When the Embedded Program algorithm is complete, the device then returns to reading array data and
addresses are no longer latched. The system can determine the status of the program operation by using
DQ7, DQ6, or RY/BY#. See Write Operation Status on page 35 for information on these status bits.
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 command sequence
should be reinitiated once the device has reset to reading array data, to ensure data integrity.
Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from
a 0 back to a 1. Attempting to do so may halt the operation and set DQ5 to 1, or cause the Data# Polling
algorithm to indicate the operation was successful. However, a succeeding read will show that the data is still
0. Only erase operations can convert a 0 to a 1.
10.6
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 10.1 on page 34 shows the
requirements for the command sequence.
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. Addresses are don’t care
for both cycles. The device then returns to reading array data.
Figure 10.1 on page 31 illustrates the algorithm for the program operation. See Erase/Program Operations
on page 46 for parameters, and to Figure 17.5 on page 46 for timing diagrams.

Chip Erase Command Sequence
Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock
cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase
command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to
preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire
memory for an all zero data pattern prior to electrical erase. The system is not required to provide any
controls or timings during these operations. Table 10.1 on page 34 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 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 35 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 10.2 on page 33 illustrates the algorithm for the erase operation. See Erase/Program Operations
on page 46 for parameters, and Figure 17.6 on page 47 for timing diagrams.

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 10.1 on page 34 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 during these operations.
After the command sequence is written, a sector erase time-out of 50 µs begins. During the time-out period,
additional sector addresses and sector erase commands may be written. However, these additional erase
commands are only one bus cycle long and should be identical to the sixth cycle of the standard erase
command explained above. 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 erasure may begin. 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. 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. The system must rewrite the command sequence and any additional sector
addresses and commands.
The system can monitor DQ3 to determine if the sector erase timer has timed out. (See DQ3: Sector Erase
Timer on page 39.) The time-out begins from the rising edge of the final WE# pulse in the command
sequence.
Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands
are ignored. Note that a hardware reset during the sector erase operation immediately terminates the
operation. The Sector Erase command sequence should be reinitiated once the device has returned to
reading array 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 Write Operation Status on page 35 for information on these status bits.)
Figure 10.2 on page 33 illustrates the algorithm for the erase operation. Refer to Erase/Program Operations
on page 46 for parameters, and to Figure 17.6 on page 47 for timing diagrams.
10.9
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 not selected for erasure. This command is valid only during the sector
erase operation, including the 50 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.
Writing the Erase Suspend command during the Sector Erase time-out immediately terminates the time-out
period and suspends the erase operation. Addresses are don’t-cares when writing the Erase Suspend
command.
When the Erase Suspend command is written during a sector erase operation, the device requires a
maximum of 35 µs to suspend the erase operation. However, when the Erase Suspend command is written
during the sector erase time-out, the device immediately terminates the time-out period and suspends the
erase operation.
After the erase operation 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 status data on DQ7–DQ0. The system can use DQ7, or DQ6 and DQ2 together, to determine if a
sector is actively erasing or is erase-suspended. See Write Operation Status on page 35 for information on
these status bits.
After an erase-suspended program operation is complete, the system can once again read array data within
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 35 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 29 for more information.
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.

11. Write Operation Status
The device provides several bits to determine the status of a write operation: DQ2, DQ3, DQ5, DQ6, DQ7,
and RY/BY#. Table 11.1 on page 39 and the following subsections describe the functions of these bits. DQ7,
RY/BY#, and DQ6 each offer a method for determining whether a program or erase operation is complete or
in progress. These three bits are discussed first.
11.1
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Algorithm is in progress or
completed, or whether the device is in Erase Suspend. Data# Polling is valid after the rising edge of the final
WE# pulse in the 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 also applies to programming during Erase Suspend. When the
Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system
must provide the program address to read valid status information on DQ7. If a program address falls within a
protected sector, Data# Polling on DQ7 is active for approximately 1 µs, then the device 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.
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 17.8 on page 48, illustrates this.
Table 11.1 on page 39 shows the outputs for Data# Polling on DQ7. Figure 11.2 on page 38 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 sector selected for
erasure. During chip erase, a valid address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 = 1 because DQ7 may change simultaneously with DQ5.
11.2
RY/BY#: Ready/Busy#
The RY/BY# is a dedicated, open-drain output pin that indicates whether an Embedded Algorithm is in
progress or complete. The RY/BY# status is valid after the rising edge of the final WE# pulse in the command
sequence. Since RY/BY# is an open-drain output, several RY/BY# pins can be tied together in parallel with a
pull-up resistor to VCC.
If the output is low (Busy), the device is actively erasing or programming. (This includes programming in the
Erase Suspend mode.) If the output is high (Ready), the device is ready to read array data (including during
the Erase Suspend mode), or is in the standby mode.
Table 11.1 on page 39 shows the outputs for RY/BY#. Figures Figure 17.1 on page 43, Figure 17.2
on page 44, Figure 17.5 on page 46 and Figure 17.6 on page 47 shows RY/BY# for read, reset, program,
and erase operations, respectively.

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 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
protected.
The system can use DQ6 and DQ2 together to determine whether a sector is actively erasing or is erasesuspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6
toggles. When the device enters the Erase Suspend mode, DQ6 stops toggling. However, the system must
also use DQ2 to determine which sectors are erasing or erase-suspended. Alternatively, the system can use
DQ7 (see DQ7: Data# Polling on page 35).
If a program address falls within a protected sector, DQ6 toggles for approximately 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.
Table 11.1 on page 39 shows the outputs for Toggle Bit I on DQ6. Figure 11.2 on page 38 shows the toggle
bit algorithm in flowchart form, and Reading Toggle Bits DQ6/DQ2 on page 38 explains the algorithm.
Figure 17.9 on page 48 shows the toggle bit timing diagrams. Figure 17.10 on page 49 shows the differences
between DQ2 and DQ6 in graphical form. See also the subsection on DQ2: Toggle Bit II on page 37.
11.4
DQ2: Toggle Bit II
The “Toggle Bit II” on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that
is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. 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 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 11.1 on page 39 to compare
outputs for DQ2 and DQ6.
Figure 11.2 on page 38 shows the toggle bit algorithm in flowchart form, and the section Reading Toggle Bits
DQ6/DQ2 on page 38 explains the algorithm. See also the DQ6: Toggle Bit I on page 37 subsection.
Figure 17.9 on page 48 shows the toggle bit timing diagram. Figure 17.10 on page 49 shows the differences
between DQ2 and DQ6 in graphical form.

Reading Toggle Bits DQ6/DQ2
Refer to Figure 11.2 on page 38 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 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 successfully completed the program or
erase operation. If it is still toggling, the device did not complete 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 11.2 on page 38).

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 conditions, the system must issue the reset command to return the device to reading array
data.
11.7
DQ3: Sector Erase Timer
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not an
erase operation has begun. (The sector erase timer does not apply to the chip erase command.) If additional
sectors are selected for erasure, the entire time-out also applies after each additional sector erase command.
When the time-out 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 Sector Erase Command Sequence on page 32.
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 will accept additional
sector erase commands. To ensure the command has been 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 11.1 shows the outputs for DQ3.

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, V CC = 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 10.1
on page 34 for further information on command definitions.
6. The device has a minimum erase and program cycle endurance of 100,000 cycles per sector.
