Notice On Data Sheet Designations
Spansion Inc. issues data sheets with Advance Information or Preliminary designations to advise readers of
product information or intended specifications throughout the product life cycle, including development,
qualification, initial production, and full production. In all cases, however, readers are encouraged to verify
that they have the latest information before finalizing their design. The following descriptions of Spansion data
sheet designations are presented here to highlight their presence and definitions.
Advance Information
The Advance Information designation indicates that Spansion Inc. is developing one or more specific
products, but has not committed any design to production. Information presented in a document with this
designation is likely to change, and in some cases, development on the product may discontinue. Spansion
Inc. therefore places the following conditions upon Advance Information content:
“This document contains information on one or more products under development at Spansion Inc.
The information is intended to help you evaluate this product. Do not design in this product without
contacting the factory. Spansion Inc. reserves the right to change or discontinue work on this proposed
product without notice.”
Preliminary
The Preliminary designation indicates that the product development has progressed such that a commitment
to production has taken place. This designation covers several aspects of the product life cycle, including
product qualification, initial production, and the subsequent phases in the manufacturing process that occur
before full production is achieved. Changes to the technical specifications presented in a Preliminary
document should be expected while keeping these aspects of production under consideration. Spansion
places the following conditions upon Preliminary content:
“This document states the current technical specifications regarding the Spansion product(s)
described herein. The Preliminary status of this document indicates that product qualification has been
completed, and that initial production has begun. Due to the phases of the manufacturing process that
require maintaining efficiency and quality, this document may be revised by subsequent versions or
modifications due to changes in technical specifications.”
Combination
Some data sheets contain a combination of products with different designations (Advance Information,
Preliminary, or Full Production). This type of document distinguishes these products and their designations
wherever necessary, typically on the first page, the ordering information page, and pages with the DC
Characteristics table and the AC Erase and Program table (in the table notes). The disclaimer on the first
page refers the reader to the notice on this page.
Full Production (No Designation on Document)
When a product has been in production for a period of time such that no changes or only nominal changes
are expected, the Preliminary designation is removed from the data sheet. Nominal changes may include
those affecting the number of ordering part numbers available, such as the addition or deletion of a speed
option, temperature range, package type, or VIO range. Changes may also include those needed to clarify a
description or to correct a typographical error or incorrect specification. Spansion Inc. applies the following
conditions to documents in this category:
“This document states the current technical specifications regarding the Spansion product(s)
described herein. Spansion Inc. deems the products to have been in sufficient production volume such
that subsequent versions of this document are not expected to change. However, typographical or
specification corrections, or modifications to the valid combinations offered may occur.”
Questions regarding these document designations may be directed to your local sales office.

7. Device Operations
This section describes the read, program, erase, handshaking, and reset features of the Flash devices.
Operations are initiated by writing specific commands or a sequence with specific address and data patterns
into the command registers (see Table 12.1 through Table 12.4). The command register itself does not
occupy any addressable memory location; rather, it 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
input to the internal state machine and the state machine outputs dictate the function of the device. Writing
incorrect address and data values or writing them in an improper sequence may place the device in an
unknown state, in which case the system must pull the RESET# pin low or power cycle the device to return
the device to the reading array data mode.
7.1
Device Operation Table
The device must be setup appropriately for each operation. Table 7.1 describes the required state of each
control pin for any particular operation.

Word/Byte Configuration
The BYTE# pin controls whether the device data I/O pins operate in the byte or word configuration. If the
BYTE# pin is set at logic ‘1’, the device is in word configuration, DQ0-DQ15 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.
7.3
VersatileIOTM (VIO) Control
The VersatileIOTM (VIO) control allows the host system to set the voltage levels that the device generates and
tolerates on all inputs and outputs (address, control, and DQ signals). VIO range is 1.65 to VCC. See Ordering
Information on page 9 for VIO options on this device.
For example, a VIO of 1.65-3.6 volts allows for I/O at the 1.8 or 3 volt levels, driving and receiving signals to
and from other 1.8 or 3 V devices on the same data bus.
7.4
Read
All memories require access time to output array data. In a read operation, data is read from one memory
location at a time. Addresses are presented to the device in random order, and the propagation delay through
the device causes the data on its outputs to arrive with the address on its inputs.
The device defaults to reading array data after device power-up or hardware reset. To read data from the
memory array, the system must first assert a valid address on Amax-A0, while driving OE# and CE# to VIL.
WE# must remain at VIH. All addresses are latched on the falling edge of CE#. Data will appear on DQ15DQ0 after address access time (tACC), which is equal to the delay from stable addresses to valid output data.
The OE# signal must be driven to VIL. Data is output on DQ15-DQ0 pins after the access time (tOE) has
elapsed from the falling edge of OE#, assuming the tACC access time has been meet.
7.5
Page Read Mode
The device is capable of fast page mode read and is compatible with the page mode Mask ROM read
operation. This mode provides faster read access speed for random locations within a page. The page size of
the device is 8 words/16 bytes. The appropriate page is selected by the higher address bits A(max)-A3.
Address bits A2-A0 in word mode (A2 to A-1 in byte mode) determine the specific word within a page. The
microprocessor supplies the specific word location.
The random or initial page access is equal to tACC or tCE and subsequent page read accesses (as long as the
locations specified by the microprocessor falls within that page) is equivalent to tPACC. When CE# is deasserted and reasserted for a subsequent access, the access time is tACC or tCE. Fast page mode accesses
are obtained by keeping the “read-page addresses” constant and changing the “intra-read page” addresses.

Autoselect
The Autoselect mode provides manufacturer ID, Device identification, and sector protection information,
through identifier codes output from the internal register (separate from the memory array) on DQ7-DQ0. This
mode is primarily intended for programming equipment to automatically match a device to be programmed
with its corresponding programming algorithm (see Table 7.3). The Autoselect codes can also be accessed
in-system.
There are two methods to access autoselect codes. One uses the autoselect command, the other applies VID
on address pin A9.
When using programming equipment, the autoselect mode requires VID (11.5 V to 12.5 V) on address pin A9.
Address pins must be as shown in Table 7.2.
„ To access Autoselect mode without using high voltage on A9, the host system must issue the Autoselect
command.
„ The Autoselect command sequence may be written to an address within a sector that is either in the read
or erase-suspend-read mode.
„ The Autoselect command may not be written while the device is actively programming or erasing.
„ The system must write the reset command to return to the read mode (or erase-suspend-read mode if the
sector was previously in Erase Suspend).
„ It is recommended that A9 apply VID after power-up sequence is completed. In addition, it is recommended
that A9 apply from VID to VIH/VIL before power-down the VCC/VIO.
„ See Table 12.1 on page 69 for command sequence details.
„ When verifying sector protection, the sector address must appear on the appropriate highest order address
bits (see Table 7.4 to Table 7.5). The remaining address bits are don't care. When all necessary bits have
been set as required, the programming equipment may then read the corresponding identifier code on
DQ15-DQ0. The Autoselect codes can also be accessed in-system through the command register.

Program/Erase Operations
These devices are capable of several modes of programming and or erase operations which are described in
detail in the following sections.
During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing address,
command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is latched on
the 1st rising edge of WE# or CE#.
The Unlock Bypass feature allows the host system to send program commands to the Flash device without
first writing unlock cycles within the command sequence. See Section 7.7.8 for details on the Unlock Bypass
function.
Note the following:
„ When the Embedded Program algorithm is complete, the device returns to the read mode.
„ The system can determine the status of the program operation by reading the DQ status bits. Refer to the
Write Operation Status on page 36 for information on these status bits.
„ An “0” cannot be programmed back to a “1.” A succeeding read shows that the data is still “0.”
„ Only erase operations can convert a “0” to a “1.”
„ Any commands written to the device during the Embedded Program/Erase are ignored except the
Suspend commands.
„ Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in
progress.
„ A hardware reset and/or power removal immediately terminates the Program/Erase operation and the
Program/Erase command sequence should be reinitiated once the device has returned to the read mode
to ensure data integrity.
„ Programming is allowed in any sequence and across sector boundaries for single word programming
operation. See Write Buffer Programming on page 26 when using the write buffer.
„ Programming to the same word address multiple times without intervening erases is permitted.
7.7.1
Single Word Programming
Single word programming mode is one method of programming the Flash. In this mode, four Flash command
write cycles are used to program an individual Flash address. The data for this programming operation could
be 8 or 16-bits wide.
While the single word programming method is supported by most Spansion devices, in general Single Word
Programming is not recommended for devices that support Write Buffer Programming. See Table 12.1
on page 69 for the required bus cycles and Figure 7.1 for the flowchart.
When the Embedded Program algorithm is complete, the device then returns to the read mode and
addresses are no longer latched. The system can determine the status of the program operation by reading
the DQ status bits. Refer to Write Operation Status on page 36 for information on these status bits.
„ During programming, any command (except the Suspend Program command) is ignored.
„ The Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in
progress.
„ A hardware reset immediately terminates the program operation. The program command sequence should
be reinitiated once the device has returned to the read mode, to ensure data integrity.
„ Programming to the same address multiple times continuously (for example, “walking” a bit within a word)
is permitted.

Write Buffer Programming
Write Buffer Programming allows the system to write a maximum of 32 words in one programming operation.
This results in a faster effective word programming time than the standard “word” programming algorithms.
The Write Buffer Programming command sequence is initiated by first writing two unlock cycles. This is
followed by a third write cycle containing the Write Buffer Load command written at the Sector Address in
which programming occurs. At this point, the system writes the number of “word locations minus 1” that are
loaded into the page buffer at the Sector Address in which programming occurs. This tells the device how
many write buffer addresses are loaded with data and therefore when to expect the “Program Buffer to Flash”
confirm command. The number of locations to program cannot exceed the size of the write buffer or the
operation aborts. (Number loaded = the number of locations to program minus 1. For example, if the system
programs 6 address locations, then 05h should be written to the device.)
The system then writes the starting address/data combination. This starting address is the first address/data
pair to be programmed, and selects the “write-buffer-page” address. All subsequent address/data pairs must
fall within the elected-write-buffer-page.
The “write-buffer-page” is selected by using the addresses AMAX–A5.
The “write-buffer-page” addresses must be the same for all address/data pairs loaded into the write buffer.
(This means Write Buffer Programming cannot be performed across multiple “write-buffer-pages.” This also
means that Write Buffer Programming cannot be performed across multiple sectors. If the system attempts to
load programming data outside of the selected “write-buffer-page”, the operation ABORTs.)
After writing the Starting Address/Data pair, the system then writes the remaining address/data pairs into the
write buffer.
Note that if a Write Buffer address location is loaded multiple times, the “address/data pair” counter is
decremented for every data load operation. Also, the last data loaded at a location before the “Program Buffer
to Flash” confirm command is the data programmed into the device. It is the software's responsibility to
comprehend ramifications of loading a write-buffer location more than once. The counter decrements for each
data load operation, NOT for each unique write-buffer-address location. Once the specified number of write
buffer locations have been loaded, the system must then write the “Program Buffer to Flash” command at the
Sector Address. Any other address/data write combinations abort the Write Buffer Programming operation.
The Write Operation Status bits should be used while monitoring the last address location loaded into the
write buffer. This eliminates the need to store an address in memory because the system can load the last
address location, issue the program confirm command at the last loaded address location, and then check
the write operation status at that same address. DQ7, DQ6, DQ5, DQ2, and DQ1 should be monitored to
determine the device status during Write Buffer Programming.

The write-buffer “embedded” programming operation can be suspended using the standard suspend/resume
commands. Upon successful completion of the Write Buffer Programming operation, the device returns to
READ mode.
The Write Buffer Programming Sequence is ABORTED under any of the following conditions:
„ Load a value that is greater than the page buffer size during the “Number of Locations to Program” step.
„ Write to an address in a sector different than the one specified during the Write-Buffer-Load command.
„ Write an Address/Data pair to a different write-buffer-page than the one selected by the “Starting Address”
during the “write buffer data loading” stage of the operation.
„ Writing anything other than the Program to Buffer Flash Command after the specified number of “data
load” cycles.
The ABORT condition is indicated by DQ1 = 1, DQ7 = DATA# (for the “last address location loaded”), DQ6 =
TOGGLE, DQ5 = 0. This indicates that the Write Buffer Programming Operation was ABORTED. A “Write-toBuffer-Abort reset” command sequence is required when using the write buffer Programming features in
Unlock Bypass mode. Note that the Secured Silicon sector, autoselect, and CFI functions are unavailable
when a program operation is in progress.
Write buffer programming is allowed in any sequence of memory (or address) locations. These flash devices
are capable of handling multiple write buffer programming operations on the same write buffer address range
without intervening erases.
Use of the write buffer is strongly recommended for programming when multiple words are to be
programmed.

Sector Erase
The sector erase function erases one or more sectors in the memory array. (See Table 12.1 on page 69 and
Figure 7.3.) The device does not require the system to preprogram a sector prior to erase. The Embedded
Erase algorithm automatically programs and verifies the entire memory to an all zero data pattern prior to
electrical erase. After a successful sector erase, all locations within the erased sector contain FFFFh. 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 no less than tSEA occurs. During the timeout period, additional sector addresses 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. Any sector erase address and command following the exceeded
time-out (50µs) may or may not be accepted. Any command other than Sector Erase or Erase Suspend
during the time-out period resets that sector to the read mode. The system can monitor DQ3 to determine if
the sector erase timer has timed out (See Section 7.8.6.) The time-out begins from the rising edge of the final
WE# pulse in the command sequence.
When the Embedded Erase algorithm is complete, the sector returns to reading array data and addresses are
no longer latched. The system can determine the status of the erase operation by reading DQ7 or DQ6/DQ2
in the erasing sector. Refer to Section 7.8 for information on these status bits.
Once the sector erase operation has begun, only the Erase Suspend command is valid. All other commands
are ignored. However, note that a hardware reset immediately terminates the erase operation. If that occurs,
the sector erase command sequence should be reinitiated once that sector has returned to reading array
data, to ensure the sector is properly erased.
The Unlock Bypass feature allows the host system to send program commands to the Flash device without
first writing unlock cycles within the command sequence. See Section 7.7.8 for details on the Unlock Bypass
function.
Figure 7.3 illustrates the algorithm for the erase operation. Refer to Section 11.7.5 for parameters and timing

Chip Erase Command Sequence
Chip erase is a six-bus cycle operation as indicated by Table 12.1 on page 69. These commands invoke the
Embedded Erase algorithm, which does not require the system to preprogram prior to erase. The Embedded
Erase algorithm automatically preprograms and verifies the entire memory to an all zero data pattern prior to
electrical erase. After a successful chip erase, all locations of the chip contain FFFFh. The system is not
required to provide any controls or timings during these operations. The Command Definitions on page 68
shows the address and data requirements for the chip erase command sequence.
When the Embedded Erase algorithm is complete, that sector returns to the read mode and addresses are no
longer latched. The system can determine the status of the erase operation by using DQ7 or DQ6/DQ2. Refer
to “Write Operation Status” for information on these status bits.
The Unlock Bypass feature allows the host system to send program commands to the Flash device without
first writing unlock cycles within the command sequence. See Section 7.7.8 for details on the Unlock Bypass
function.
Any commands written during the chip erase operation are ignored. However, note that a hardware reset
immediately terminates the erase operation. If that occurs, the chip erase command sequence should be
reinitiated once that sector has returned to reading array data, to ensure the entire array is properly erased.

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. The sector address is required when writing this
command. This command is valid only during the sector erase operation, including the minimum tSEA time-out
period during the sector erase command sequence. The Erase Suspend command is ignored if written during
the chip erase operation.
When the Erase Suspend command is written during the sector erase operation, the device requires a
maximum of 20 µs (5 µs typical) 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 device enters the erase-suspend-read mode. The system
can read data from or program data to any sector not selected for erasure. (The device “erase suspends” all
sectors selected for erasure.) Reading at any address within erase-suspended sectors produces status
information 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. Refer to Table 7.35 for information on these status bits.
After an erase-suspended program operation is complete, the device returns to the erase-suspend-read
mode. The system can determine the status of the program operation using write operation status bits, just as
in the standard program operation.
In the erase-suspend-read mode, the system can also issue the Autoselect command sequence. Refer to
Write Buffer Programming on page 26 and the Autoselect on page 21 for details.
To resume the sector erase operation, the system must write the Erase Resume command. The address of
the erase-suspended sector is required when writing this command. Further writes of the Resume command
are ignored. Another Erase Suspend command can be written after the chip has resumed erasing.

Program Suspend/Program Resume Commands
The Program Suspend command allows the system to interrupt an embedded programming operation or a
“Write to Buffer” programming operation so that data can read from any non-suspended sector. When the
Program Suspend command is written during a programming process, the device halts the programming
operation within 15 µs maximum (5 µs typical) and updates the status bits. Addresses are “don't-cares” when
writing the Program Suspend command.
After the programming operation has been suspended, the system can read array data from any nonsuspended sector. The Program Suspend command may also be issued during a programming operation
while an erase is suspended. In this case, data may be read from any addresses not within a sector in Erase
Suspend or Program Suspend. If a read is needed from the Secured Silicon Sector area, then user must use
the proper command sequences to enter and exit this region.
The system may also write the Autoselect Command Sequence when the device is in Program Suspend
mode. The device allows reading Autoselect codes in the suspended sectors, since the codes are not stored
in the memory array. When the device exits the Autoselect mode, the device reverts to Program Suspend
mode, and is ready for another valid operation. See Autoselect on page 21 for more information.
After the Program Resume command is written, the device reverts to programming. The system can
determine the status of the program operation using the write operation status bits, just as in the standard
program operation. See Write Operation Status on page 36 for more information.
The system must write the Program Resume command (address bits are “don't care”) to exit the Program
Suspend mode and continue the programming operation. Further writes of the Program Resume command
are ignored. Another Program Suspend command can be written after the device has resumed programming.

Accelerated Program
Accelerated single word programming and write buffer programming operations are enabled through the
WP#/ACC pin. This method is faster than the standard program command sequences.
Note
The accelerated program functions must not be used more than 10 times per sector.
If the system asserts VHH on this input, the device automatically enters the aforementioned Unlock Bypass
mode and uses the higher voltage on the input to reduce the time required for program operations. The
system can then use the Write Buffer Load command sequence provided by the Unlock Bypass mode. Note
that if a “Write-to-Buffer-Abort Reset” is required while in Unlock Bypass mode, the full 3-cycle RESET
command sequence must be used to reset the device. Removing VHH from the ACC input, upon completion
of the embedded program operation, returns the device to normal operation.
„ Sectors must be unlocked prior to raising WP#/ACC to VHH.
„ The WP#/ACC pin must not be at VHH for operations other than accelerated programming, or device
damage may result.
„ It is recommended that WP#/ACC apply VHH after power-up sequence is completed. In addition, it is
recommended that WP#/ACC apply from VHH to VIH/VIL before powering down VCC/VIO.
7.7.8
Unlock Bypass
This device features an Unlock Bypass mode to facilitate shorter programming commands. Once the device
enters the Unlock Bypass mode, only two write cycles are required to program data, instead of the normal
four cycles.
This mode dispenses with the initial two unlock cycles required in the standard program command sequence,
resulting in faster total programming time. The Command Definitions on page 68 shows the requirements for
the unlock bypass command sequences.
During the unlock bypass mode, only the Read, Program, Write Buffer Programming, Write-to-Buffer-Abort
Reset, 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 sector address
and the data 90h. The second cycle need only contain the data 00h. The sector then returns to the read
mode.
Software Functions and Sample Code
The following are C source code examples of using the unlock bypass entry, program, and exit functions.

Write Operation Status
The device provides several bits to determine the status of a program or erase operation. The following
subsections describe the function of DQ1, DQ2, DQ3, DQ5, DQ6, and DQ7.
7.8.1
DQ7: Data# Polling
The Data# Polling bit, DQ7, indicates to the host system whether an Embedded Program or Erase 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 command sequence. Note that the Data# Polling is valid only for the last
word being programmed in the write-buffer-page during Write Buffer Programming. Reading Data# Polling
status on any word other than the last word to be programmed in the write-buffer-page returns false status
information.
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, then that sector returns to the read mode.
During the Embedded Erase Algorithm, Data# polling produces a “0” on DQ7. When the Embedded Erase
algorithm is complete, or if the device enters the Erase Suspend mode, Data# Polling produces a “1” on DQ7.
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 the read mode. If not all selected
sectors are protected, the Embedded Erase algorithm erases the unprotected sectors, and ignores the
selected sectors that are protected. However, if the system reads DQ7 at an address within a protected
sector, the status may not be valid.
Just prior to the completion of an Embedded Program or Erase operation, DQ7 may change asynchronously
with DQ6-DQ0 while Output Enable (OE#) is asserted low. That is, the device may change from providing
status information to valid data on DQ7. Depending on when the system samples the DQ7 output, it may read

data, the data outputs on DQ6-DQ0 may be still invalid. Valid data on DQ7-D00 appears on successive read
cycles.

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 that is
being programmed or erased causes DQ6 to toggle. 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 100μs, 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 36).
If a program address falls within a protected sector, DQ6 toggles for approximately 1μs 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.
See the following for additional information: Figure 7.4, Figure 11.13 on page 64, and Table 7.17.
Toggle Bit I on DQ6 requires either OE# or CE# to be de-asserted and reasserted to show the change in
state.
7.8.3
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. 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 7.17 to compare
outputs for DQ2 and DQ6. See Figure 11.14 on page 64 for additional information.
7.8.4
Reading Toggle Bits DQ6/DQ2
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 erases 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 DQ5: Exceeded Timing Limits on page 39). 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 erases
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. Refer to Figure 7.4 for
more details.
Note
When verifying the status of a write operation (embedded program/erase) of a memory sector, DQ6 and DQ2
toggle between high and low states in a series of consecutive and contiguous status read cycles. In order for
38

S29GL-P_00_A11 June 11, 2008

She et
this toggling behavior to be properly observed, the consecutive status bit reads must not be interleaved with
read accesses to other memory sectors. If it is not possible to temporarily prevent reads to other memory
sectors, then it is recommended to use the DQ7 status bit as the alternative method of determining the active
or inactive status of the write operation.
7.8.5
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,” indicating that the program or erase cycle was not successfully
completed. The device does not output a 1 on DQ5 if the system tries to program a 1 to a location that was
previously programmed to 0. Only an erase operation can change a 0 back to a 1. Under this condition, the
device ignores the bit that was incorrectly instructed to be programmed from a 0 to a 1, while any other bits
that were correctly requested to be changed from 1 to 0 are programmed. Attempting to program a 0 to a 1 is
masked during the programming operation. Under valid DQ5 conditions, the system must write the reset
command to return to the read mode (or to the erase-suspend-read mode if a sector was previously in the
erase-suspend-program mode).
7.8.6
DQ3: Sector Erase Timeout State Indicator
After writing a sector erase command sequence, the system may read DQ3 to determine whether or not
erasure 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 period is complete, DQ3 switches from a “0” to a “1.” If the time between additional sector erase
commands from the system can be assumed to be less than tSEA, then the system need not monitor DQ3.
See Sector Erase on page 30 for more details.
After the sector erase command is written, the system should read the status of DQ7 (Data# Polling) or DQ6
(Toggle Bit I) to ensure that the device has accepted the command sequence, and then read DQ3. If DQ3 is
“1,” the Embedded Erase algorithm has begun; all further commands (except Erase Suspend) are ignored
until the erase operation is complete. If DQ3 is “0,” the device accepts 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 sub-sequent sector erase command. If DQ3 is high on the second status check, the last
command might not have been accepted. Table 7.17 shows the status of DQ3 relative to the other status bits.
7.8.7
DQ1: Write to Buffer Abort
DQ1 indicates whether a Write to Buffer operation was aborted. Under these conditions DQ1 produces a “1”.
The system must issue the “Write to Buffer Abort Reset” command sequence to return the device to reading
array data. See Write Buffer Programming on page 26 for more details.

7.9
Writing Commands/Command Sequences
During a write operation, the system must drive CE# and WE# to VIL and OE# to VIH when providing an
address, command, and data. Addresses are latched on the last falling edge of WE# or CE#, while data is
latched on the 1st rising edge of WE# or CE#. An erase operation can erase one sector, multiple sectors, or
the entire device. Table 6.2–Table 6.3 indicate the address space that each sector occupies. The device
address space is divided into uniform 64KW/128KB sectors. A sector address is the set of address bits
required to uniquely select a sector. ICC2 in “DC Characteristics” represents the active current specification for
the write mode. “AC Characteristics” contains timing specification tables and timing diagrams for write
operations.
7.9.1
RY/BY#
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. This feature allows the host system to detect when data is ready to be read by simply
monitoring the RY/BY# pin, which is a dedicated output and controlled by CE# (not OE#).
7.9.2
Hardware Reset
The RESET# input provides a hardware method of resetting the device to reading array data. When RESET#
is driven low for at least a period of tRP (RESET# Pulse Width), the device immediately terminates any
operation in progress, tristates all outputs, resets the configuration register, 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.
To ensure data integrity Program/Erase operations that were interrupted should be reinitiated once the device
is ready to accept another command sequence.
When RESET# is held at VSS, the device draws VCC reset current (ICC5). If RESET# is held at VIL, but not at
VSS, the standby current is greater. RESET# may be tied to the system reset circuitry which enables the
system to read the boot-up firmware from the Flash memory upon a system reset. See Figure 11.7
on page 59 and Figure 11.8 on page 60 for timing diagrams.

Software Reset
Software reset is part of the command set (see Table 12.1 on page 69) that also returns the device to array
read mode and must be used for the following conditions:
1. to exit Autoselect mode
2. when DQ5 goes high during write status operation that indicates program or erase cycle was not
successfully completed
3. exit sector lock/unlock operation.
4. to return to erase-suspend-read mode if the device was previously in Erase Suspend mode.

The following are additional points to consider when using the reset command:
„ This command resets the sectors to the read and address bits are ignored.
„ Reset commands are ignored during program and erase operations.
„ The reset command may be written between the cycles in a program command sequence before
programming begins (prior to the third cycle). This resets the sector to which the system was writing to the
read mode.
„ If the program command sequence is written to a sector that is in the Erase Suspend mode, writing the
reset command returns that sector to the erase-suspend-read mode.
„ The reset command may be written during an Autoselect command sequence.
„ If a sector has entered the Autoselect mode while in the Erase Suspend mode, writing the reset command
returns that sector to the erase-suspend-read mode.
„ If DQ1 goes high during a Write Buffer Programming operation, the system must write the “Write to Buffer
Abort Reset” command sequence to RESET the device to reading array data. The standard RESET
command does not work during this condition.
„ To exit the unlock bypass mode, the system must issue a two-cycle unlock bypass reset command
sequence [see Command Definitions on page 68 for details].

For programming lock register bits refer to Table 12.2 on page 70 and Table 12.4 on page 72.
Notes
1. If the password mode is chosen, the password must be programmed before setting the
corresponding lock register bit.
2. After the Lock Register Bits Command Set Entry command sequence is written, reads and writes
for Sector 0 are disabled, while reads from other sectors are allowed until exiting this mode.
3. If both lock bits are selected to be programmed (to zeros) at the same time, the operation aborts.
4. Once the Password Mode Lock Bit is programmed, the Persistent Mode Lock Bit is permanently
disabled, and no changes to the protection scheme are allowed. Similarly, if the Persistent Mode
Lock Bit is programmed, the Password Mode is permanently disabled.
After selecting a sector protection method, each sector can operate in any of the following three states:
1. Constantly locked. The selected sectors are protected and can not be reprogrammed unless PPB
lock bit is cleared via a password, hardware reset, or power cycle.
2. Dynamically locked. The selected sectors are protected and can be altered via software
commands.
3. Unlocked. The sectors are unprotected and can be erased and/or programmed.
These states are controlled by the bit types described in Section 8.2–Section 8.5.
8.2
Persistent Protection Bits
The Persistent Protection Bits are unique and nonvolatile for each sector and have the same endurances as
the Flash memory. Preprogramming and verification prior to erasure are handled by the device, and therefore
do not require system monitoring.
Notes
1. Each PPB is individually programmed and all are erased in parallel.
2. While programming PPB for a sector, array data can be read from any other sector, except Sector
0 (used for Data# Polling) and the sector in which sector PPB is being programmed.
3. Entry command disables reads and writes for the sector selected.
4. Reads within that sector return the PPB status for that sector.
5. All Reads must be performed using the read mode.
6. The specific sector address (A25-A16 GL01GP, A24-A16 GL512P, A23-A16 GL256P, A22-A16
GL128P) are written at the same time as the program command.
7. If the PPB Lock Bit is set, the PPB Program or erase command does not execute and times-out
without programming or erasing the PPB.

Dynamic Protection Bits
Dynamic Protection Bits are volatile and unique for each sector and can be individually modified. DYBs only
control the protection scheme for unprotected sectors that have their PPBs cleared (erased to “1”). By issuing
the DYB Set or Clear command sequences, the DYBs are set (programmed to “0”) or cleared (erased to “1”),
thus placing each sector in the protected or unprotected state respectively. This feature allows software to
easily protect sectors against inadvertent changes yet does not prevent the easy removal of protection when
changes are needed.
Notes
1. The DYBs can be set (programmed to “0”) or cleared (erased to “1”) as often as needed. When the
parts are first shipped, the PPBs are cleared (erased to “1”) and upon power up or reset, the
DYBs can be set or cleared depending upon the ordering option chosen.
2. If the option to clear the DYBs after power up is chosen, (erased to “1”), then the sectorsmay be
modified depending upon the PPB state of that sector (see Table 8.2).
3. The sectors would be in the protected state If the option to set the DYBs after power up is chosen
(programmed to “0”).
4. It is possible to have sectors that are persistently locked with sectors that are left in the dynamic
state.
5. The DYB Set or Clear commands for the dynamic sectors signify protected or unprotectedstate of
the sectors respectively. However, if there is a need to change the status of the persistently locked
sectors, a few more steps are required. First, the PPB Lock Bit must be cleared by either putting
the device through a power-cycle, or hardware reset. The PPBs can then be changed to reflect the
desired settings. Setting the PPB Lock Bit once again locks the PPBs, and the device operates
normally again.
6. To achieve the best protection, it is recommended to execute the PPB Lock Bit Set command early
in the boot code and protect the boot code by holding WP#/ACC = VIL. Note that the PPB and DYB
bits have the same function when WP#/ACC = VHH as they do when ACC =VIH.
8.3
Persistent Protection Bit Lock Bit
The Persistent Protection Bit Lock Bit is a global volatile bit for all sectors. When set (programmed to “0”), it
locks all PPBs and when cleared (programmed to “1”), allows the PPBs to be changed. There is only one
PPB Lock Bit per device.
Notes
1. No software command sequence unlocks this bit unless the device is in the password protection
mode; only a hardware reset or a power-up clears this bit.
2. The PPB Lock Bit must be set (programmed to “0”) only after all PPBs are configured to the
desired settings.
8.4
Password Protection Method
The Password Protection Method allows an even higher level of security than the Persistent Sector Protection
Mode by requiring a 64-bit password for unlocking the device PPB Lock Bit. In addition to this password
requirement, after power up and reset, the PPB Lock Bit is set “0” to maintain the password mode of
operation. Successful execution of the Password Unlock command by entering the entire password clears the
PPB Lock Bit, allowing for sector PPBs modifications.
Notes
1. There is no special addressing order required for programming the password. Once the Password
is written and verified, the Password Mode Locking Bit must be set in order to prevent access.
2. The Password Program Command is only capable of programming “0”s. Programming a “1” after a
cell is programmed as a “0” results in a time-out with the cell as a “0”.
3. The password is all “1”s when shipped from the factory.
4. All 64-bit password combinations are valid as a password.

S29GL-P MirrorBit® Flash Family
45
D at a
S hee t
5. There is no means to verify what the password is after it is set.
6. The Password Mode Lock Bit, once set, prevents reading the 64-bit password on the data bus and
further password programming.
7. The Password Mode Lock Bit is not erasable.
8. The lower two address bits (A1–A0) are valid during the Password Read, Password Program, and
Password Unlock.
9. The exact password must be entered in order for the unlocking function to occur.
10. The Password Unlock command cannot be issued any faster than 1 µs at a time to prevent a
hacker from running through all the 64-bit combinations in an attempt to correctly match a
password.
11. Approximately 1 µs is required for unlocking the device after the valid 64-bit password is given to
the device.
12. Password verification is only allowed during the password programming operation.
13. All further commands to the password region are disabled and all operations are ignored.
14. If the password is lost after setting the Password Mode Lock Bit, there is no way to clear the PPB
Lock Bit.
15. Entry command sequence must be issued prior to any of any operation and it disables reads and
writes for Sector 0. Reads and writes for other sectors excluding Sector 0 are allowed.
16. If the user attempts to program or erase a protected sector, the device ignores the command and
returns to read mode.
17. A program or erase command to a protected sector enables status polling and returns to read
mode without having modified the contents of the protected sector.
18. The programming of the DYB, PPB, and PPB Lock for a given sector can be verified by writing
individual status read commands DYB Status, PPB Status, and PPB Lock Status to the device.

sector. In summary, if the PPB Lock Bit is locked (set to “0”), no changes to the PPBs are allowed. The PPB
Lock Bit can only be unlocked (reset to “1”) through a hardware reset or power cycle. See also Figure 8.1 for
an overview of the Advanced Sector Protection feature.
8.6
Hardware Data Protection Methods
The device offers two main types of data protection at the sector level via hardware control:
„ When WP#/ACC is at VIL, the either the highest or lowest sector is locked (device specific).
There are additional methods by which intended or accidental erasure of any sectors can be prevented via
hardware means. The following subsections describes these methods:
8.6.1
WP#/ACC Method
The Write Protect feature provides a hardware method of protecting one outermost sector. This function is
provided by the WP#/ACC pin and overrides the previously discussed Sector Protection/Unprotection
method.
If the system asserts VIL on the WP#/ACC pin, the device disables program and erase functions in the
highest or lowest sector independently of whether the sector was protected or unprotected using the method
described in Advanced Sector Protection/Unprotection on page 42.
If the system asserts VIH on the WP#/ACC pin, the device reverts to whether the boot sectors were last set to
be protected or unprotected. That is, sector protection or unprotection for these sectors depends on whether
they were last protected or unprotected.
The WP#/ACC pin must be held stable during a command sequence execution. WP# has an internal pull-up;
when unconnected, WP# is set at VIH.
Note
If WP#/ACC is at VIL when the device is in the standby mode, the maximum input load current is increased.
See Table 11.6 on page 56 for details.
8.6.2
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 to reading
array data. Subsequent writes are ignored until VCC is greater than VLKO. The system must provide the
proper signals to the control inputs to prevent unintentional writes when VCC is greater than VLKO.

8.6.3
She et
Write Pulse “Glitch Protection”
Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.
8.6.4
Power-Up Write Inhibit
If WE# = CE# = RESET# = 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 the read mode on power-up.
9. Power Conservation Modes
9.1
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#
inputs are both held at VCC ± 0.3 V. The device requires standard access time (tCE) for read access, 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. ICC4 in “DC Characteristics” represents the standby current
specification
9.2
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. ICC6 in Section 11.6
represents the automatic sleep mode current specification.
9.3
Hardware RESET# Input Operation
The RESET# input provides a hardware method of resetting the device to reading array data. When RESET#
is driven low for at least a period of tRP, the device immediately terminates any operation in progress, tristates
all outputs, 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.
When RESET# is held at VSS ± 0.3 V, the device draws ICC reset current (ICC5). If RESET# is held at VIL but
not within VSS ± 0.3 V, the standby current is greater.
RESET# may be tied to the system reset circuitry and thus, a system reset would also reset the Flash
memory, enabling the system to read the boot-up firmware from the Flash memory.
9.4
Output Disable (OE#)
When the OE# input is at VIH, output from the device is disabled. The outputs are placed in the high
impedance state. (With the exception of RY/BY#.)

10. Secured Silicon Sector Flash Memory Region
The Secured Silicon Sector provides an extra Flash memory region that enables permanent part identification
through an Electronic Serial Number (ESN). The Secured Silicon Sector is 128 words in length and all
Secured Silicon reads outside of the 128-word address range returns invalid data. The Secured Silicon
Sector Indicator Bit, DQ7, (at Autoselect address 03h) is used to indicate whether or not the Secured Silicon
Sector is locked when shipped from the factory.
Please note the following general conditions:
„ On power-up, or following a hardware reset, the device reverts to sending commands to the normal
address space.
„ Reads outside of sector SA0 return memory array data.
„ Sector SA0 is remapped from memory array to Secured Silicon Sector array.
„ Once the Secured Silicon Sector Entry Command is issued, the Secured Silicon Sector Exit command
must be issued to exit Secured Silicon Sector Mode.
„ The Secured Silicon Sector is not accessible when the device is executing an Embedded Program or
Embedded Erase algorithm.
„ The ACC function and unlock bypass modes are not available when the Secured Silicon Sector is enabled.

Factory Locked Secured Silicon Sector
The Factory Locked Secured Silicon Sector is always protected when shipped from the factory and has the
Secured Silicon Sector Indicator Bit (DQ7) permanently set to a “1”. This prevents cloning of a factory locked
part and ensures the security of the ESN and customer code once the product is shipped to the field.
These devices are available pre-programmed with one of the following:
„ A random, 8 Word secure ESN only within the Secured Silicon Sector (at addresses 000000H - 000007H)
„ Both a random, secure ESN and customer code through the Spansion programming service.
Customers may opt to have their code programmed through the Spansion programming services. 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 your local representative for
details on using Spansion programming services.

Customer Lockable Secured Silicon Sector
The Customer Lockable Secured Silicon Sector is always shipped unprotected (DQ7 set to “0”), allowing
customers to utilize that sector in any manner they choose. If the security feature is not required, the Secured
Silicon Sector can be treated as an additional Flash memory space.
Please note the following:
„ Once the Secured Silicon Sector area is protected, the Secured Silicon Sector Indicator Bit is permanently
set to “0.”
„ The Secured Silicon Sector can be read any number of times, but can be programmed and locked only
once. The Secured Silicon Sector lock must be used with caution as once locked, there is no procedure
available for unlocking the Secured Silicon Sector area and none of the bits in the Secured Silicon Sector
memory space can be modified in any way.
„ The accelerated programming (ACC) and unlock bypass functions are not available when the Secured
Silicon Sector is enabled.
„ Once the Secured Silicon Sector is locked and verified, the system must write the Exit Secured Silicon
Sector Region command sequence which return the device to the memory array at sector 0.
10.3
Secured Silicon Sector Entry/Exit Command Sequences
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.
See Command Definitions on page 68 [Secured Silicon Sector Command Table, Appendix
Table 12.1 on page 69 through Table 12.4 on page 72 for address and data requirements for both command
sequences.
The Secured Silicon Sector Entry Command allows the following commands to be executed
„ Read customer and factory Secured Silicon areas
„ Program the customer Secured Silicon Sector
After the system has written the Enter Secured Silicon Sector command sequence, it may read the Secured
Silicon Sector by using the addresses normally occupied by sector SA0 within the memory array. This mode
of operation continues until the system issues the Exit Secured Silicon Sector command sequence, or until
power is removed from the device.
Software Functions and Sample Code
The following are C functions and source code examples of using the Secured Silicon Sector Entry, Program,
and exit commands. Refer to the Spansion Low Level Driver User’s Guide (available soon on

Notes
1. Typical program and erase times assume the following conditions: 25°C, 3.6 V VCC, 10,000 cycles, checkerboard pattern.
2. Under worst case conditions of -40°C, VCC = 3.0 V, 100,000 cycles.
3. Effective write buffer specification is based upon a 32-word write buffer operation.
4. In the pre-programming step of the Embedded Erase algorithm, all bits 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 Tables 12.1–12.4.

Command Definitions
Writing specific address and data commands or sequences into the command register initiates device
operations. Tables 12.1–12.4 define the valid register command sequences. Writing incorrect address and
data values or writing them in the improper sequence can place the device in an unknown state. A reset
command is then required to return the device to reading array data.

Legend
X = Don’t care
RA = Address of the memory to be read.
RD = Data read from location RA during read operation.
PA = Address of the memory location to be programmed. Addresses latch on
the falling edge of the WE# or CE# pulse, whichever happens later.
Notes
1. See Table 7.1 on page 19 for description of bus operations.
2. All values are in hexadecimal.
3. All bus cycles are write cycles unless otherwise noted.
4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles.
5. Address bits AMAX:A16 are don’t cares for unlock and command cycles,
unless SA or PA required. (AMAX is the Highest Address pin.).
6. No unlock or command cycles required when reading array data.
7. The Reset command is required to return to reading array data when
device is in the autoselect mode, or if DQ5 goes high (while the device is
providing status data).
8. See Table 7.2 on page 22 for device ID values and definitions.
9. The fourth, fifth, and sixth cycles of the autoselect command sequence are
read cycles.
10. The data is 00h for an unprotected sector and 01h for a protected sector.
See Autoselect on page 21 for more information. This is same as PPB
Status Read except that the protect and unprotect statuses are inverted
here.
PD = Data to be programmed at location PA. Data latches on the rising edge
of the WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased.
Address bits Amax–A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same write
buffer page as PA.
WC = Word Count is the number of write buffer locations to load minus 1.
11. The data value for DQ7 is “1” for a serialized, protected Secured Silicon
Sector region and “0” for an unserialized, unprotected region. See
Table 7.3 on page 22 for data and definitions.
12. Command is valid when device is ready to read array data or when device
is in autoselect mode.
13. Command sequence returns device to reading array after being placed in
a Write-to-Buffer-Abort state. Full command sequence is required if
resetting out of abort while in Unlock Bypass mode.
14. The Unlock-Bypass command is required prior to the Unlock-BypassProgram command.
15. The Unlock-Bypass-Reset command is required to return to reading array
data when the device is in the unlock bypass mode.
16. The system can read and program/program suspend in non-erasing
sectors, or enter the autoselect mode, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase
operation.
17. The Erase Resume/Program Resume command is valid only during the
Erase Suspend/Program Suspend modes.
18. The Exit command returns the device to reading the array.

Notes
1. See Table 7.1 on page 19 for description of bus operations.
7. The Exit command returns the device to reading the array.
2. All values are in hexadecimal.
8. If any Command Set Entry command was written, an Exit command must
be issued to reset the device into read mode.
3. All bus cycles are write cycles unless otherwise noted.
4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles.
5. Address bits AMAX:A16 are don’t cares for unlock and command cycles,
unless SA or PA required. (AMAX is the Highest Address pin.)
6. All Lock Register bits are one-time programmable. Program state = “0” and
the erase state = “1.” The Persistent Protection Mode Lock Bit and the
Password Protection Mode Lock Bit cannot be programmed at the same
time or the Lock Register Bits Program operation aborts and returns the
device to read mode. Lock Register bits that are reserved for future use
default to “1’s.” The Lock Register is shipped out as “FFFF’s” before Lock
Register Bit program execution.
70
9. For PWDx, only one portion of the password can be programmed per each
“A0” command.
10. Note that the password portion can be entered or read in any order as long
as the entire 64-bit password is entered or read.
11. If ACC = VHH, sector protection matches when ACC = VIH.
12. Protected State = “00h,” Unprotected State = “01h.”
13. The All PPB Erase command embeds programming of all PPB bits before
erasure.

Notes
1. See Table 7.1 on page 19 for description of bus operations.
2. All values are in hexadecimal.
3. All bus cycles are write cycles unless otherwise noted.
4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles.
5. Address bits AMAX:A16 are don’t cares for unlock and command cycles,
unless SA or PA required. (AMAX is the Highest Address pin.).
6. No unlock or command cycles required when reading array data.
7. The Reset command is required to return to reading array data when
device is in the autoselect mode, or if DQ5 goes high (while the device is
providing status data).
8. See Table 7.2 on page 22 for device ID values and definitions.
9. The fourth, fifth, and sixth cycles of the autoselect command sequence are
read cycles.
10. The data is 00h for an unprotected sector and 01h for a protected sector.
See Autoselect on page 21 for more information. This is same as PPB
Status Read except that the protect and unprotect statuses are inverted
here.
PD = Data to be programmed at location PA. Data latches on the rising edge
of the WE# or CE# pulse, whichever happens first.
SA = Address of the sector to be verified (in autoselect mode) or erased.
Address bits Amax–A16 uniquely select any sector.
WBL = Write Buffer Location. The address must be within the same write
buffer page as PA.
WC = Word Count is the number of write buffer locations to load minus 1.
11. The data value for DQ7 is “1” for a serialized, protected Secured Silicon
Sector region and “0” for an unserialized, unprotected region. See
Table 7.3 on page 22 for data and definitions.
12. Command is valid when device is ready to read array data or when device
is in autoselect mode.
13. Command sequence returns device to reading array after being placed in
a Write-to-Buffer-Abort state. Full command sequence is required if
resetting out of abort while in Unlock Bypass mode.
14. The Unlock-Bypass command is required prior to the Unlock-BypassProgram command.
15. The Unlock-Bypass-Reset command is required to return to reading array
data when the device is in the unlock bypass mode.
16. The system can read and program/program suspend in non-erasing
sectors, or enter the autoselect mode, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase
operation.
17. The Erase Resume/Program Resume command is valid only during the
Erase Suspend/Program Suspend modes.
18. The Exit command returns the device to reading the array.

Notes
1. See Table 7.1 on page 19 for description of bus operations.
7. The Exit command returns the device to reading the array.
8. If any Command Set Entry command was written, an Exit command must
be issued to reset the device into read mode.
2. All values are in hexadecimal.
3. All bus cycles are write cycles unless otherwise noted.
4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles.
5. Address bits AMAX:A16 are don’t cares for unlock and command cycles,
unless SA or PA required. (AMAX is the Highest Address pin.)
6. All Lock Register bits are one-time programmable. Program state = “0” and
the erase state = “1.” The Persistent Protection Mode Lock Bit and the
Password Protection Mode Lock Bit cannot be programmed at the same
time or the Lock Register Bits Program operation aborts and returns the
device to read mode. Lock Register bits that are reserved for future use
default to “1’s.” The Lock Register is shipped out as “FFFF’s” before Lock
Register Bit program execution.

9. For PWDx, only one portion of the password can be programmed per each
“A0” command.
10. Note that the password portion can be entered or read in any order as long
as the entire 64-bit password is entered or read.
11. If ACC = VHH, sector protection matches when ACC = VIH.
12. Protected State = “00h,” Unprotected State = “01h.”
13. The All PPB Erase command embeds programming of all PPB bits before
erasure.

Common Flash Memory Interface
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 any time the device is ready to read array data. The system can read CFI information at the addresses
given in Tables 12.6–12.8). All reads outside of the CFI address range, returns non-valid data. Reads from
other sectors are allowed, writes are not. 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 Tables 12.6–12.8.
The system must write the reset command to return the device to reading array data.
The following is a C source code example of using the CFI Entry and Exit functions. Refer to the Spansion
Low Level Driver User’s Guide (available on www.spansion.com) for general information on Spansion Flash
memory software development guidelines.
/* Example: CFI Entry command */
*( (UINT16 *)base_addr + 0x55 ) = 0x0098;
/* Example: CFI Exit command */
*( (UINT16 *)base_addr + 0x000 ) = 0x00F0;
/* write CFI entry command
/* write cfi exit command
*/
*/
For further information, please refer to the CFI Specification (see JEDEC publications JEP137-A and
JESD68.01and CFI Publication 100). Please contact your sales office for copies of these documents.
