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.

Device Operations
This section describes the read, program, erase, simultaneous read/write operations, 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 Tables 11.1 and 11.2). 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 write the reset command to return the device to the reading array data mode.
6.1
Device Operation Table
The device must be setup appropriately for each operation. Table 6.1 describes the required state of each
control pin for any particular operation.

Notes
1. Address is latched on the rising edge of clock.
2. CLK must stay low or high after CE# goes low when device in Asynchronous Read mode.
6.2
Asynchronous Read
All memories require access time to output array data. In an asynchronous 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 asynchronously with the address on its
inputs.
To read data from the memory array, the system must first assert a valid address while driving AVD# and
CE# to VIL. WE# must remain at VIH. The rising edge of AVD# latches the address. The OE# signal must be
driven to VIL, once AVD# has been driven to VIH.
The data is output on A/DQ15 – A/DQ0 pins after the access time (tOE) has elapsed from the falling edge of
OE#.

Synchronous (Burst) Read Operation
The device is capable of continuous sequential burst operation and linear burst operation of a preset length.
When the device first powers up, it is enabled for Asynchronous read and can be automatically enabled for
burst mode and the address is latched on the first rising edge of CLK input, while AVD# is held low for one
clock cycle.
Prior to activating the clock signal, the system should determine how many wait states are desired for the
initial word (tIACC) of each burst access, what mode of burst operation is desired and how the RDY signal
transitions with valid data. The system would then write the configuration register command sequence.
At startup the system writes the Set Configuration Register command sequence to optimize the system
performance.
The data is output tIACC after the rising edge of the first CLK. Subsequent words are output tBACC after the
rising edge of each successive clock cycle, which automatically increments the internal address counter.
Note that data is output only at the rising edge of the clock. RDY indicates the initial latency.
Note that the device has a fixed internal address boundary that occurs every 128 words. No boundary
crossing latency is required when the device operates with wait states set from 2 to 9.

Continuous Burst Read Mode
In the continuous burst read mode, the device outputs sequential burst data from the starting address given
and then wraps around to address 000000h when it reaches the highest addressable memory location. The
burst read mode continues until the system drives CE# high, or RESET= VIL. Continuous burst mode can
also be aborted by asserting AVD# low and providing a new address to the device.
If the address being read crosses a 128-word line boundary within the same bank, but not into a program or
erase suspended sector, as mentioned above, additional latency cycles are required as reflected by the
configuration register table (Table 6.11) and Tables 6.2 – 6.9 .
If the address crosses a bank boundary while the subsequent bank is programming or erasing, the device
provides read status information and the clock is ignored. Upon completion of status read or program or erase
operation, the host can restart a burst read operation using a new address and AVD# pulse.

8-Word, 16-Word, and 32-Word Linear Burst Read with Wrap Around
In a linear burst read operation, a fixed number of words (8, 16, or 32 words) are read from consecutive
addresses that are determined by the group within which the starting address falls. The groups are sized
according to the number of words read in a single burst sequence for a given mode (see Table 6.10).
For example, if the starting address in the 8-word mode is 3Ch, the address range to be read is 38-3Fh, and
the burst sequence is 3C-3D-3E-3F-38-39-3A-3Bh. Thus, the device outputs all words in that burst address
group until all word are read, regardless of where the starting address occurs in the address group, and then
terminates the burst read.
In a similar fashion, the 16-word and 32-word Linear Wrap modes begin their burst sequence on the starting
address provided to the device, then wrap back to the first address in the selected address group.
Note that in this mode the address pointer does not cross the boundary that occurs every 128 words; thus, no
additional wait states are inserted due to boundary crossing.

00 – 1Fh, 20 – 3Fh, 40 – 5Fh,...
8-Word, 16-Word, and 32-Word Linear Burst without Wrap Around
If wrap around is not enabled for linear burst read operations, the 8-word, 16-word, or 32-word burst executes
up to the maximum memory address of the selected number of words. The burst stops after 8, 16, or 32
addresses and does not wrap around to the first address of the selected group.
For example, if the starting address in the 8-word mode is 3Ch, the address range to be read is 3C-43h, and
the burst sequence is 3C-3D-3E-3F-40-41-42-43h if wrap around is not enabled. The next address to be read
requires a new address and AVD# pulse. Note that in this burst read mode, the address pointer may cross the
boundary that occurs every 128 words, which incurs the additional boundary crossing wait state.
6.3.5
Configuration Registers
This device uses two 16-bit configuration registers to set various operational parameters. Upon power-up or
hardware reset, the device is capable of the asynchronous read mode and synchronous read, and the
configuration register settings are in their default state. The host system should determine the proper settings
for the entire configuration register, and then execute the Set Configuration Register command sequence
before attempting burst operations. The Configuration Register can also be read using a command sequence
(see Table 11.1). The following list describes the register settings.

Autoselect
The Autoselect is used for manufacturer ID, Device identification, and sector protection information. This
mode is primarily intended for programming equipment to automatically match a device with its corresponding
programming algorithm. The Autoselect codes can also be accessed in the system. When verifying sector
protection, the sector address must appear on the appropriate highest order address bits (see Table 6.12).
The remaining address bits are don't care. The most significant four bits of the address during the third write
cycle select the bank from which the Autoselect codes are read by the host. All other banks can be accessed
normally for data read without exiting the Autoselect mode.

To access the Autoselect codes, the host system must issue the Autoselect command.
The Autoselect command sequence may be written to an address within a bank that is either in the read or
erase-suspend-read mode.
The Autoselect command may not be written while the device is actively programming or erasing.
Autoselect does not support simultaneous operations or burst mode.
The system must write the reset command to return to the read mode (or erase-suspend-read mode if the
bank was previously in Erase Suspend).

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. However, prior to any programming and or erase operation, devices can be
setup appropriately as outlined in the configuration register (Table 6.11).
For any program and or erase operations, including writing command sequences, the system must drive
AVD# and CE# to VIL, and OE# to VIH when providing an address to the device, and drive WE# and CE# to
VIL, and OE# to VIH when writing commands or programming data.
All addresses are latched on the rising edge of AVD# or falling edge of WE#, and all data is latched on the
first rising edge of WE#.
Note the following:
When the Embedded Program/Erase algorithm is complete, the device returns to the read mode.
The system can determine the status of the Program/Erase operation. Refer to the Write Operation Status
section for further information.
While 1 can be programmed to 0, a 0 cannot be programmed to a 1. Any such attempt is ignored as only
an erase operation can covert a 0 to a 1.
Any commands written to the device during the Embedded Program/Erase Algorithm are ignored except
the Program/Erase Suspend command.
Secured Silicon Sector, Autoselect, and CFI functions are unavailable when a program operation is in
progress.
A hardware reset 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 only for single word programming
operation. See Write Buffer Programming when using the write buffer.
Note: The system may also lock or unlock any sector while the erase operation is suspended.
6.5.1
Single Word Programming
Single word programming mode is the simplest method of programming. In this mode, four Flash command
write cycles are used to program an individual Flash address. While the single word programming method is
supported by all Spansion devices, in general it is not recommended for devices that support Write Buffer
Programming. See Table 11.1 for the required bus cycles and Figure 6.2 for the flowchart.

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 is loaded into
the page buffer at the Sector Address in which programming occurs. This tells the device how many write
buffer addresses will be 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. (Note: the size of the write buffer is dependent upon which data are being loaded. Also note that the
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
be in sequential order.
The write-buffer addresses must be in the same sector for all address/data pairs loaded into the write buffer.
It is to be noted that Write Buffer Programming cannot be performed across multiple sectors. If the system
attempts to load programming data outside of the selected write-buffer addresses, the operation aborts after
the Write to Buffer command is executed. Also, the starting address must be the least significant address and
must be incremental and that the write buffer data cannot be in different sectors.
After writing the Starting Address/Data pair, the system then writes the remaining address/data pairs into the
write buffer. Write buffer locations must be loaded in sequential order starting with the lowest address in the
page. Note that if the number of address/data pairs do not match the word count, the program buffer to flash
command is ignored.
Note that if a Write Buffer address location is loaded multiple times, the address/data pair counter
decrements for every data load operation. Also, the last data loaded at a location before the Program Buffer
to Flash confirm command is 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 device then goes busy. The Data Bar polling techniques 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 data bar poll 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 in the following ways:
Load a value that is greater than the buffer size during the Number of Locations to Program step (DQ7 is
not valid in this condition).
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.
Write data other than the Confirm Command after the specified number of data load cycles.

Sector Erase
The sector erase function erases one or more sectors in the memory array. (See Table 11.1 and Figure 6.4.)
The device does not require the system to preprogram prior to erase. The Embedded Erase algorithm
automatically programs and verifies the entire memory for 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 and sector erase commands may be written. Loading the sector erase
buffer may be done in any sequence, and the number of sectors may be from one sector to all sectors. The
time between these additional cycles must be less than tSEA. Any sector erase address and command
following the exceeded time-out (tSEA) may or may not be accepted. Any command other than Sector Erase
or Erase Suspend during the time-out period resets that bank to the read mode. The system can monitor DQ3

to determine if the sector erase timer has timed out (See the section, DQ3: Sector Erase Timeout State
Indicator.) 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 bank returns to reading array data and addresses are
no longer latched. Note that while the Embedded Erase operation is in progress, the system can read data
from the non-erasing banks. The system can determine the status of the erase operation by reading DQ7 or
DQ6/DQ2 in the erasing bank. Refer to Write Operation Status 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 bank has returned to reading array data,
to ensure data integrity.
Figure 6.4 illustrates the algorithm for the erase operation. Refer to Program/Erase Operations for

Chip Erase Command Sequence
Chip erase is a six-bus cycle operation as indicated by Table 11.1. 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 for 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. Table 11.1 shows the address and data
requirements for the chip erase command sequence.
When the Embedded Erase algorithm is complete, that bank 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 the Write Operation Status section for information on these status bits.

Any commands written during the chip erase operation are ignored. However, note that a hardware reset
immediately terminates the erase operation. If that occurs, the chip erase command sequence should be
reinitiated once that bank has returned to reading array data, to ensure data integrity.

Erase Suspend/Erase Resume Commands
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. 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 bank 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 after the tSEA time-out period has expired and during the sector
erase operation, the device requires a maximum of tESL (erase suspend latency) to suspend the erase
operation.
After the erase operation has been suspended, the bank 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 6.27 for information on these status bits.
After an erase-suspended program operation is complete, the bank returns to the erase-suspend-read mode.
The system can determine the status of the program operation using the DQ7 or DQ6 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 the
Write Buffer Programming section and the Autoselect section for details.
To resume the sector erase operation, the system must write the Erase Resume command. The bank
address of the erase-suspended bank 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.
Note: While an erase operation can be suspended and resumed multiple times, a minimum delay of tERS
(Erase Resume to Suspend) is required from resume to the next suspend.

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 tPSL (program suspend latency) 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 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 the Autoselect section 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 DQ7 or DQ6 status bits, just as in the standard
program operation. See the Write Operation Status section 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.
Note: While a program operation can be suspended and resumed multiple times, a minimum delay of tPRS
(Program Resume to Suspend) is required from resume to the next suspend.

Accelerated Program/Sector Erase
Accelerated single word programming, write buffer programming and sector erase, operations are enabled
through the VPP function. This method is faster than the standard chip program and erase command
sequences.
The accelerated chip program and erase functions must not be used more than 100 times per sector.
In addition, accelerated chip program and erase should be performed at room temperature
(30°C ±10°C).
If the system asserts VHH on this input, the device automatically enters the accelerated mode and uses the
higher voltage on the input to reduce the time required for program and erase 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 VPP input, upon completion of the
embedded program or erase operation, returns the device to normal operation.
Sectors must be unlocked prior to raising VPP to VHH.
The VPP pin must not be at VHH for operations other than accelerated programming and accelerated sector
erase, or device damage may result.
The VPP pin must not be left floating or unconnected; inconsistent behavior of the device may result.
VPP locks all sector if set to VIL; VPP should be set to VIH for all other conditions.
6.5.8
Unlock Bypass
The unlock bypass feature allows the system to primarily program to a bank 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. The host system may also initiate the chip
erase and sector erase sequences in the unlock bypass mode. The erase command sequences are four
cycles in length instead of six cycles. Table 11.1 shows the requirements for the unlock bypass command
sequences.
During the unlock bypass mode, only the Read, Unlock Bypass Program, Unlock Bypass Sector Erase,
Unlock Bypass Chip Erase, 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 bank address and the data 90h. The second cycle need only contain the data 00h. The bank then returns
to the read mode.
The device offers accelerated program operations through the VPP input. When the system asserts VHH on
this input, the device automatically enters the Unlock Bypass mode. The system may then write the two-cycle
Unlock Bypass program command sequence. The device uses the higher voltage on the VPP input to
accelerate the operation.

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.
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 a bank 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. Similarly, attempting to program 1 over a 0 does not return valid Date# 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. 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 tPSP, then that bank returns to the read
mode.
During the Embedded Erase Algorithm, Data# polling produces a 0 on DQ7. When the Embedded Erase
algorithm is complete, or if the bank enters the Erase Suspend mode, Data# Polling produces a 1 on DQ7.
The system must provide an address 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 tASP, then the bank 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-DQ1 while Output Enable (OE#) is asserted low. That is, the device may change from providing
status information to valid data on DQ7. Even if the device has completed the program or erase operation and
DQ7 has valid data, the data outputs on DQ6-DQ1 may be still invalid. Valid data on DQ7-D01 appears on
successive read cycles.
See the following for more information: Table 6.27, Write Operation Status, shows the outputs for Data#
Polling on DQ7. Table 6.5, Write Operation Status Flowchart, shows the Data# Polling algorithm; and
Figure 10.15, Data# Polling Timings (During Embedded Algorithm), shows the Data# Polling timing diagram.

7) Data polling algorithm valid for all operations except advanced sector protection.
8) It can fail if one tries to program DQ7 from '0' to '1'
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 in the
same bank, 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. 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 tASP [all sectors protected toggle time], 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 the subsection on DQ7: Data# Polling).
If a program address falls within a protected sector, DQ6 toggles for approximately tPSP 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 6.5, Write Operation Status Flowchart; Figure 10.16,
Toggle Bit Timings (During Embedded Algorithm), and Tables 6.26 and 6.27.
Toggle Bit I on DQ6 requires either OE# or CE# to be de-asserted and reasserted to show the change in state
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 6.26 to compare
outputs for DQ2 and DQ6. See the following for additional information: Figure 6.5, the DQ6: Toggle Bit I
section, and Figures 10.15 – 10.18.

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 notes and stores the value of the toggle bit
after the first read. After the second read, the system compares 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 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 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 6.5 for more details.
Note: When verifying the status of a write operation (embedded program/erase) of a memory bank, DQ6 and
DQ2 toggle between high and low states in a series of consecutive and contiguous status read cycles. In
order for this toggling behavior to be properly observed, the consecutive status bit reads must not be
interleaved with read accesses to other memory banks. If it is not possible to temporarily prevent reads to

(Adva nce
In for m ation)
other memory banks, 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.
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 may 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 halts the operation, and when the timing limit has been exceeded, DQ5 produces a 1. Under both
these conditions, the system must write the reset command to return to the read mode (or to the erasesuspend-read mode if a bank was previously in the erase-suspend-program mode).
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, the system need not monitor DQ3. See the
Sector Erase Command Sequence, 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 6.27 shows the status of DQ3 relative to the other status bits.
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 Operation for more details.

Simultaneous Read/Write
The simultaneous read/write feature allows the host system to read data from one bank of memory while
programming or erasing another bank of memory. An erase operation may also be suspended to read from or
program another location within the same bank (except the sector being erased). Figure 10.21, Back-to-Back
Read/Write Cycle Timings, shows how read and write cycles may be initiated for simultaneous operation with
zero latency. Refer to the DC Characteristics table for read-while-program and read-while-erase current
specification.
6.7
Writing Commands/Command Sequences
When the device is in Asynchronous read, only Asynchronous write operations are allowed. During an
asynchronous 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 rising edge of AVD#, while data is latched on the
rising edge of WE#. An erase operation can erase one sector, multiple sectors, or the entire device. Table 5.1
– Table 5.3 indicate the address space that each sector occupies. The device address space is divided into
sixteen banks: for NS512P, all 16 banks contain 64-Kword sectors while for NS256P and NS128P, Banks 0
through 14 contain only 64 Kword sectors, Bank 15 contains 16-Kword boot sectors in addition to 64 Kword
sectors. A bank address is the set of address bits required to uniquely select a bank. Similarly, a sector
address is the address bits required to uniquely select a sector. ICC2 in the DC Characteristics section
represents the active current specification for the write mode. AC Characteristics-Synchronous and AC
Characteristics-Asynchronous contain timing specification tables and timing diagrams for write operations.
6.8
Handshaking
The handshaking feature allows the host system to detect when data is ready to be read by simply monitoring
the RDY pin which is a dedicated output and is controlled by CE#.
6.9
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, 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 the operation that was interrupted should be reinitiated once the device is ready to
accept another command sequence.
When RESET# is held at VSS, the device draws CMOS standby current (ICC4). 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 Figures 10.5 and 10.11 for timing diagrams.
6.10
Software Reset
Software reset is part of the command set (see Table 11.1) 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.
5. after any aborted operations
6. exiting read configuration registration Mode

*( (UINT16 *)base_addr + 0x000 ) = 0x00F0;
The following are additional points to consider when using the reset command:
This command resets the banks to the read and address bits are ignored.
Reset commands are ignored once erasure has begun until the operation is complete.
Once programming begins, the device ignores reset commands until the operation is complete
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 bank to which the system was writing to the
read mode.
If the program command sequence is written to a bank that is in the Erase Suspend mode, writing the reset
command returns that bank to the erase-suspend-read mode.
The reset command may be also written during an Autoselect command sequence.
If a bank has entered the Autoselect mode while in the Erase Suspend mode, writing the reset command
returns that bank 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 table for details].

Programmable Output Slew Rate Control
This feature allows the user to change the output slew rate during a read operation by setting the
configuration register bit CR1.4. It allows 2 programmable slew rates. This feature is for users who do not
want to run the part at its maximum speed and could live with a slower output slew rate thereby reducing
noise variations at the output.

device can only be used in the Persistent Protection Mode. When the device is set to Password Protection
Mode, DQ1 is required to be set to 1 and DQ2 is required to be set to 0. DQ3 is programmed in the Spansion
factory. When the device is programmed to disable all PPB erase command, DQ3 outputs a 0, when the lock
register bits are read. Similarly, if the device is programmed to enable all PPB erase command, DQ3 outputs
a 1 when the lock register bits are read. Likewise the DQ4 bit is also programmed in the Spansion Factory.
DQ4 is the bit which indicates whether Volatile Sector Protection Bit (DYB) is protected or not after boot up.
When the device is programmed to set all Volatile Sector Protection Bit protected after power up, DQ4
outputs a 0 when the lock register bits are read. Similarly, when the device is programmed to set all Volatile
Sector Protection Bit unprotected after power up, DQ4 outputs a 1. Each of these bits in the lock register are
non-volatile. DQ15 – DQ5 are reserved and are 1s.

2. It is recommended that a sector protection method to be chosen by programming DQ1 or DQ2
prior to shipment
3. After the Lock Register Bits Command Set Entry command sequence is written, reads and writes
for Bank 0 are disabled, while reads from other banks are allowed until exiting this mode.
4. If both lock bits are selected to be programmed (to zeros) at the same time, the operation aborts.
5. 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.
6. During erase/program suspend, ASP entry commands are not allowed.
7. Data Polling can be done immediately after the lock register programming command sequence (no
delay required). Note that status polling can be done only in bank 0.
8. Reads from other banks (simultaneous operation) are not allowed during lock register
programming. This restriction applies to both synchronous and asynchronous read operations.
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 Sections 7.2 – 7.6.
7.2
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 bank, except Bank 0
(used for Data# Polling) and the bank in which sector PPB is being programmed.
3. Entry command disables reads and writes for the bank selected.
4. Reads within that bank return the PPB status for that sector.
5. Reads from other banks are allowed while writes are not allowed.
6. All Reads must be performed using the Asynchronous mode.
7. The specific sector address (Amax – A14) are written at the same time as the program command.
8. If the PPB Lock Bit is set, the PPB Program or erase command does not execute and time out
without programming or erasing the PPB.
9. There are no means for individually erasing a specific PPB and no specific sector address is
required for this operation.
10. PPB exit command must be issued after the execution which resets the device to read mode and
re-enables reads and writes for Bank 0
11. The programming state of the PPB for a given sector can be verified by writing a PPB Status Read
Command to the device as described by the flow chart shown in Figure 7.2.
12. During PPB program/erase data polling can be done synchronously.
13. If customers attempt to program or erase a protected sector, the device ignores the command and
returns to read mode.

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.
2. When the parts are first shipped, the DYBs are set and programmed to 0 upon power up or reset.
3. The default state of DYB is protected after power up and all sectors can be modified depending on
the status of PPB bit for that sector, (erased to 1). Then the sectors can be modified depending
upon the PPB state of that sector (see Table 7.1).
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# = VIL.
7. Data polling is not available for DYB program/erase.
8. DYB read data can be done synchronously.
9. If customers attempt to program or erase a protected sector, the device ignores the command and
returns to read mode.
7.4
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. If the password mode is chosen, then the password must be programmed and verified before
setting the corresponding lock register bit.
2. 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.
3. The PPB Lock Bit must be set (programmed to 0) only after all PPBs are configured to the desired
settings.
7.5
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 0s. 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 1s when shipped from the factory.
4. All 64-bit password combinations are valid as a password.
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 Bank 0. Reads and writes for other banks excluding Bank 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.

Hardware Data Protection Methods
The device offers two main types of data protection at the sector level via hardware control:
When WP# is at VIL, the highest two sectors are locked (device specific).
When VPP is at VIL, all sectors are locked.
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:
WP# Method
The Write Protect feature provides a hardware method of protecting the highest two sectors (NS256P and
NS128P). This function is provided by the WP# pin and overrides the previously discussed Sector Protection/
Unprotection method.
If the system asserts VIL on the WP# pin, the device disables program and erase functions in the highest two
sectors (NS256P and NS128P) as well as Secured Silicon Area.
If the system asserts VIH on the WP# 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.
Note that the WP# pin must not be left floating or unconnected as inconsistent behavior of the device may
result.
The WP# pin must be held stable during a command sequence execution
VPP Method
This method is similar to above, except it protects all sectors (including the Secured Silicon Area). Once VPP
input is set to VIL, all program and erase functions are disabled and hence all sectors are protected.
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.
Write Pulse Glitch Protection
Noise pulses of less than 3 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.
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.

Power Conservation Modes
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 ± 0.2 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. ICC3 in the DC Characteristics section represents the standby current
specification
8.2
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption while in asynchronous mode. the
device automatically enables this mode when addresses remain stable for tACC + 20 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. While in synchronous mode, the automatic sleep mode is disabled. Note that a new burst
operation is required to provide new data. ICC6 in the DC Characteristics section represents the automatic
sleep mode current specification.
8.3
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, 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. 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 ± 0.2 V, the device draws CMOS standby current (ICC4). If RESET# is held at
VIL but not within VSS ± 0.2 V, the standby current is greater.
RESET# may be tied to the system reset circuitry and thus, a system reset also resets the Flash memory,
enabling the system to read the boot-up firmware from the Flash memory.
8.4
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.

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 256 words in length that consists
of 128 words for factory data and 128 words for customer-secured areas. All Secured Silicon reads outside of
the 256-word address range returns invalid data. The Factory Indicator Bit, DQ7, (at Autoselect address 03h)
is used to indicate whether or not the Factory Secured Silicon Sector is locked when shipped from the factory.
The Customer Indicator Bit (DQ6) is used to indicate whether or not the Customer Secured Silicon Sector is
locked when shipped from the factory.
Please note the following general conditions:
While Secured Silicon Sector access is enabled, simultaneous operations are allowed except for Bank 0.
On power-up, or following a hardware reset, the device reverts to sending commands to the normal
address space.
Reads can be performed in the Asynchronous or Synchronous mode.
Burst mode reads within Secured Silicon Sector wrap from address FFh back to address 00h.
Reads outside of sector 0 return memory array data.
Continuous burst read past the maximum address is undefined.
Sector 0 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.

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 Factory Secured Silicon Sector
Customer code within the Customer Secured Silicon Sector through the SpansionTM programming service.
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 Factory Secured Silicon Sector and Customer Secured Silicon Sector permanently
locked. Contact your local representative for details on using Spansion programming services.
9.2
Customer Secured Silicon Sector
The Customer Secured Silicon Sector is typically shipped unprotected (DQ6 set to 0), allowing customers to
utilize that sector in any manner they choose. If the security feature is not required, the Customer Secured
Silicon Sector can be treated as an additional Flash memory space.
Please note the following:
Once the Customer Secured Silicon Sector area is protected, the Customer Indicator Bit is permanently
set to 1.

The Customer Secured Silicon Sector can be read any number of times, but can be programmed and
locked only once. The Customer Secured Silicon Sector lock must be used with caution as once locked,
there is no procedure available for unlocking the Customer Secured Silicon Sector area and none of the
bits in the Customer Secured Silicon Sector memory space can be modified in any way.
The accelerated programming (VPP) and unlock bypass functions are not available when programming the
Customer Secured Silicon Sector, but reading in Banks 1 through 15 is available.
Once the Customer 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.
9.3
Secured Silicon Sector Entry and 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 Definition Table [Secured Silicon Sector Command Table, Appendix
Table 11.1 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 (www.spansion.com) for general
information on Spansion Flash memory software development guidelines.

Notes
1. Typical program and erase times assume the following conditions: 25°C, 1.8 V VCC, 10,000 cycles using checkerboard patterns.
2. Under worst case conditions of 90°C, VCC = 1.70 V, 100,000 cycles.
3. In the pre-programming step of the Embedded Erase algorithm, all words are programmed to 00h before erasure.
4. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table 11.1,
Memory Array Commands on page 78 and Table 11.2, Sector Protection Commands on page 80for further information on command
definitions.

Notes
1. See Table 6.1 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the following, all bus cycles are write cycle: read cycle, fourth through sixth cycles of the Autoselect commands, fourth cycle of
the configuration register verify and password verify commands, and any cycle reading at RD(0) and RD(1).
4. Data bits DQ15 – DQ8 are don’t care in command sequences, except for RD, PD, WD, PWD, and PWD3 – PWD0.
5. Unless otherwise noted, address bits Amax – A14 are don’t cares.
6. Writing incorrect address and data values or writing them in the improper sequence may place the device in an unknown state. The
system must write the reset command to return the device to reading array data.
7. No unlock or command cycles required when bank is reading array data.
8. The Reset command is required to return to reading array data (or to the erase-suspend-read mode if previously in Erase Suspend) when
a bank is in the autoselect mode, or if DQ5 goes high (while the bank is providing status information) or performing sector lock/unlock.
9. The fourth cycle of the autoselect address is a read cycle. The system must provide the bank address.
10. (BA) + 0Eh ----> For NS128 = 43h, NS256 = 41h, NS512 = 3Fh (BA) + 0Fh ----> For NS128/256/512 = 00h
11. The data is 0000h for an unlocked sector and 0001h for a locked sector
12. See Table 6.12, Autoselect Addresses on page 34.
13. The Unlock Bypass command sequence is required prior to this command sequence.
14. The Unlock Bypass Reset command is required to return to reading array data when the bank is in the unlock bypass mode.
15. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode. The
Program/Erase Suspend command is valid only during a program/ erase operation, and requires the bank address.
16. The Program/Erase Resume command is valid only during the Program/Erase Suspend mode, and requires the bank address.
17. The total number of cycles in the command sequence is determined by the number of words written to the write buffer. The maximum
number of cycles in the command sequence is 37.
18. Write Buffer Programming can be initiated after Unlock Bypass Entry.
19. Data is always output at the rising edge of clock.
20. Do not enter wrong address or data cycles.
21. Do not use 0x30 for CR data (otherwise in the erase suspend --> CR read or set sequence, the device will go into erase resume instead
of CR read or set).
22. Software reset is needed after CR read (otherwise the device is still in CR read mode).
23. When device is in Unlock Bypass mode, do not enter another command before Unlock Bypass reset command is issued).
24. Configuration Registers can not be programmed out of order. CR0 must be programmed prior to CR01 otherwise the configuration
registers retain their previous settings.

11.1
Common Flash Memory Interface
The Common Flash Interface (CFI) specification outlines device and host system software interrogation
handshake, which allows specific vendor-specified soft-ware algorithms to be used for entire families of
devices. Software support can then be device-independent, JEDEC ID-independent, and forward-compatible
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
(BA)55h any time the device is ready to read array data. The system can read CFI information at the
addresses given in Tables 11.3 – 11.6) within that bank. All reads outside of the CFI address range, within the
bank, returns non-valid data. Reads from other banks are allowed, writes are not. To terminate reading CFI
data, the system must write the reset command.
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 (www.spansion.com) for general information on Spansion Flash memory
software development guidelines.
/* Example: CFI Entry command */
*( (UINT16 *)bank_addr + 0x0055 = 0x0098;
/* Example: CFI Exit command */
*( (UINT16 *)bank_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.
