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.

The devices operate within the temperature range of –25 °C to +85 °C, and are offered Very Thin FBGA
packages.
Simultaneous Read/Write Operations with Zero Latency
The Simultaneous Read/Write architecture divides the memory space into four banks. The device allows a
host system to program or erase in one bank, then immediately and simultaneously read from another bank,
with zero latency. This releases the system from waiting for the completion of program or erase operations.
The devices are structured as shown in the following tables:

The devices use Chip Enable (CE#), Write Enable (WE#), Address Valid (AVD#) and Output Enable (OE#) to
control asynchronous read and write operations. For burst operations, the devices additionally require Ready
(RDY) and Clock (CLK). This implementation allows easy interface with minimal glue logic to
microprocessors/microcontrollers for high performance read operations.
The devices offer complete compatibility with the JEDEC 42.4 single-power-supply Flash command set
standard. Commands are written to the command register using standard microprocessor write timings.
Reading data out of the device are similar to reading from other Flash or EPROM devices.
The host system can detect whether a program or erase operation is complete by using the device status bit
DQ7 (Data# Polling). After a program or erase cycle has been completed, the device automatically returns to
reading array data.
The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the
data contents of other sectors. The devices are fully erased when shipped from the factory.
Hardware data protection measures include a low VCC detector that automatically inhibits write operations
during power transitions. The devices also offer three types of data protection at the sector level. The sector

lock/unlock command sequence disables or re-enables both program and erase operations in any sector.
When at VIL, WP# locks the highest two sectors. Finally, when Acc is at VIL, all sectors are locked.
The devices offer two power-saving features. When addresses have been stable for a specified amount of
time, the device enters the automatic sleep mode. The system can also place the device into the standby
mode. Power consumption is greatly reduced in both modes.

7. Device Bus Operations
This section describes the requirements and use of the device bus operations, which are initiated through the
internal command register. The command register itself does not occupy any addressable memory location.
The register is composed of latches that store the commands, along with the address and data information
needed to execute the command. The contents of the register serve as inputs to the internal state machine.
The state machine outputs dictate the function of the device. Table 7.1 lists the device bus operations, the
inputs and control levels they require, and the resulting output. The following subsections describe each of
these operations in further detail.

7.1
Requirements for Asynchronous Read Operation (Non-Burst)
To read data from the memory array, the system must assert a valid address on A/DQ15–A/DQ0 and Amax
A16, while AVD# and CE# are at VIL. WE# should remain at VIH. Note that CLK must remain at VIL during
asynchronous read operations. The rising edge of AVD# latches the address, after which the system can
drive OE# to VIL. The data will appear on A/DQ15–A/DQ0. (See Figure 14.5.) Since the memory array is
–
divided into four banks, each bank remains enabled for read access until the command register contents are
altered.
Address access time (tACC) is equal to the delay from stable addresses to valid output data. The chip enable
access time (tCE) is the delay from the stable addresses and stable CE# to valid data at the outputs. The
output enable access time (tOE) is the delay from the falling edge of OE# to valid data at the output.
The internal state machine is set for reading array data upon device power-up, or after a hardware reset. This
ensures that no spurious alteration of the memory content occurs during the power transition.
7.2
Requirements for Synchronous (Burst) Read Operation
The device is capable of seven different burst read modes (see Table 8.9): continuous burst read; 8-, 16-, and
32-word linear burst reads with wrap around; and 8-, 16-, and 32-word linear burst reads without wrap
around.
7.2.1
Continuous Burst
When the device first powers up, it is enabled for asynchronous read operation. The device will automatically
be enabled for burst mode and addresses will be latched on the first rising edge on the 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 session. The system would then write the
Set Configuration Register command sequence.
The initial word is output tIACC after the rising edge of the first CLK cycle. Subsequent words are output tBACC
after the rising edge of each successive clock cycle, which automatically increments the internal address
counter. Note that the device has a fixed internal address boundary that occurs every 64 words,
starting at address 00003Fh. The transition from the highest address to 000000h is also a boundary

D a t a S h e e t
crossing. During a boundary crossing, there is a two-cycle latency between the valid read at address
00003Eh and the valid read at address 00003Fh (or between addresses offset from these values by the same
multiple of 64 words). RDY is deasserted during the two-cycle latency, and it is reasserted in the third cycle to
indicate that the data at address 00003Fh (or offset from 3Fh by a multiple of 64 words) is ready. See
Figure 14.13.
The device will continue to output continuous, sequential burst data, wrapping around to address 000000h
after it reaches the highest addressable memory location, until the system asserts CE# high, RESET# low, or
AVD# low in conjunction with a new address. See Table 7.1. The reset command does not terminate the
burst read operation.
If the host system crosses the bank boundary while reading in burst mode, and the device is not programming
or erasing, a two-cycle latency will occur as described above. If the host system crosses the bank boundary
while the device is programming or erasing, the device will provide asynchronous read status information.
The clock will be ignored. After the host has completed status reads, or the device has completed the
program or erase operation, the host can restart a burst operation using a new address and AVD# pulse.
If the clock frequency is less than 6 MHz during a burst mode operation, additional latencies will occur. RDY
indicates the length of the latency by pulsing low.
7.2.2
8-, 16-, and 32-Word Linear Burst with Wrap Around
These three modes are of the linear wrap around design, in which a fixed number of words are read from
consecutive addresses. In each of these modes, the burst addresses read 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 7.2.)
Table 7.2 Burst Address Groups
Mode
8-word
16-word
32-word
Group Size
8 words
Group Address Ranges
0-7h, 8-Fh, 10-17h, 18-1Fh...
16 words
32 words
0-Fh, 10-1Fh, 20-2Fh, 30-3Fh...
00-1Fh, 20-3Fh, 40-5Fh, 60-7Fh...
As an example: if the starting address in the 8-word mode is 39h, the address range to be read would be 38-
3Fh, and the burst sequence would be 39-3A-3B-3C-3D-3E-3F-38h. The burst sequence begins with the
starting address written to the device, but wraps back to the first address in the selected group. In a similar
fashion, the 16-word and 32-word Linear Wrap modes begin their burst sequence on the starting address
written to the device, and then wrap back to the first address in the selected address group. Note that in
these three burst read modes the address pointer does not cross the boundary that occurs every 64
words; thus, no wait states are inserted (except during the initial access).
7.2.3
8-, 16-, and 32-Word Linear Burst without Wrap Around
In these modes, a fixed number of words (predefined as 8,16,or 32 words) are read from consecutive
addresses starting with the initial word, which is written to the device. When the number of words has been
read completely, the burst read operation stops and the RDY output goes low. There is no group limitation
and is different from the Linear Burst with Wrap Around.
See Table 8.9 and Table 8.16 for the command of setting the 8-, 16-, and 32- Word Burst without Wrap
Around.
As an example, for 8-word length Burst Read, if the starting address written to the device is 39h, the burst
sequence would be 39-3A-3B-3C-3D-3E-3F-40h, and the read operation will be terminated at 40h. In a
similar fashion, the 16-word and 32-word modes begin their burst sequence on the starting address written to
the device, and Continuously Read to the predefined word length, 16 or 32 words.
The operation is similar to the Continuous Burst, but will stop the operation at fixed word length. It is possible
the device crosses the fixed internal address boundary that occurs every 64 words during burst read; a
latency occurs before data appears for the next address and RDY is pulsing low. If the host system crosses
the bank boundary, the device will react in the same manner as in the Continuous Burst.
If the clock frequency is less than 6 MHz during a burst mode operation, additional latencies will occur. RDY
indicates the length of the latency by pulsing low.

7.3
Programmable Wait State
The programmable wait state feature indicates to the device the number of additional clock cycles that must
elapse after AVD# is driven active before data will be available. Upon power up, the device defaults to the
maximum of seven total cycles. The total number of wait states is programmable from two to seven cycles.
The wait state command sequence requires three cycles; after the two unlock cycles, the third cycle address
should be written according to the desired wait state as shown in Table 8.9. Address bits A11-A0 should be
set to 555h, while addresses bits A17-A12 set the wait state. For further details, see Section 8.3, Set
Configuration Register Command Sequence on page 36.
7.3.1
Handshaking Feature
The handshaking feature allows the host system to simply monitor the RDY signal from the device to
determine when the initial word of burst data is ready to be read. The host system should use the wait state
command sequence to set the number of wait states for optimal burst mode operation (03h for 54 MHz clock).
The initial word of burst data is indicated by the rising edge of RDY after OE# goes low.
7.4
7.5
Simultaneous Read/Write Operations with Zero Latency
This device is capable of reading data from one bank of memory while programming or erasing in one of the
other three banks of memory. An erase operation may also be suspended to read from or program to another
location within the same bank (except the sector being erased). Figure 14.16 shows how read and write
cycles may be initiated for simultaneous operation with zero latency. Refer to the Section 11., DC
Characteristics on page 51 table for read-while-program and read-while-erase current specifications.
Writing Commands/Command Sequences
The device has inputs/outputs that accept both address and data information. To write a command or
command sequence (which includes programming data to the device and erasing sectors of memory), 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 data.
The device features an Unlock Bypass mode to facilitate faster programming. Once the device enters the
Unlock Bypass mode, only two write cycles are required to program a word, instead of four.
An erase operation can erase one sector, multiple sectors, or the entire device. Table 7 indicates the address
space that each sector occupies. The device address space is divided into four banks: Bank A contains both
8 Kword boot sectors in addition to 32 Kword sectors, while Banks B, C, and D contain only 32 Kword sectors.
A “bank address” is the address bits required to uniquely select a bank. Similarly, a “sector address” is the
address bits required to uniquely select a sector.
Refer to the DC Characteristics table for write mode current specifications. The AC Characteristics section
contains timing specification tables and timing diagrams for write operations.
7.5.1
Accelerated Program Operation
The device offers accelerated program operations through the Acc input. This function is primarily intended to
allow faster manufacturing throughput at the factory. If the system asserts VID 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 would use a two-cycle program command
sequence as required by the Unlock Bypass mode. Removing VID from the Acc input returns the device to
normal operation.
7.5.2
Autoselect Functions
If the system writes the autoselect command sequence, the device enters the autoselect mode. The system
can then read autoselect codes from the internal register (which is separate from the memory array) on DQ7–
DQ0. Standard read cycle timings apply in this mode. See Section 7.5.2, Autoselect Functions on page 21
and Section 8.6, Autoselect Command Sequence on page 38 for more information.

7.6
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 when the device is in either of these standby
modes, before it is ready to read data.
If the device is deselected during erasure or programming, the device draws active current until the operation
is completed.
I
CC3 in DC Characteristics represents the standby current specification.
7.7
7.8
Automatic Sleep Mode
The automatic sleep mode minimizes Flash device energy consumption. The device automatically enters this
mode when addresses remain stable for tACC + 60 ns. The automatic sleep mode is independent of the CE#,
WE#, and OE# control signals. Standard address access timings provide new data when addresses are
changed. While in sleep mode, output data is latched and always available to the system. ICC4 in DC
Characteristics represents the automatic sleep mode current specification.
RESET#: Hardware Reset Input
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.
Current is reduced for the duration of the RESET# pulse. 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
will be greater.
RESET# may be tied to the system reset circuitry. A system reset would thus also reset the Flash memory,
enabling the system to read the boot-up firmware from the Flash memory.
If RESET# is asserted during a program or erase operation, the device requires a time of tREADYW (during
Embedded Algorithms) before the device is ready to read data again. If RESET# is asserted when a program
or erase operation is not executing, the reset operation is completed within a time of tREADY (not during
Embedded Algorithms). The system can read data tRH after RESET# returns to VIH.
Refer to the AC Characteristics tables for RESET# parameters and to Figure 14.6 for the timing diagram.
7.8.1
V
Power-up and Power-down Sequencing
CC
The device imposes no restrictions on VCC power-up or power-down sequencing. Asserting RESET# to VIL is
required during the entire VCC power sequence until the respective supplies reach their operating voltages.
Once VCC attains its operating voltage, de-assertion of RESET# to VIH is permitted.
7.9
Output Disable Mode
When the OE# input is at VIH, output from the device is disabled. The outputs are placed in the high
impedance state.
7.10 Hardware Data Protection
The command sequence requirement of unlock cycles for programming or erasing provides data protection
against inadvertent writes (refer to Table 8.16 for command definitions).
The device offers three types of data protection at the sector level:
The sector lock/unlock command sequence disables or re-enables both program and erase operations in
any sector.

S29NS-J
S29NS-J_00_A11 February 7, 2007

When WP# is at VIL,
– SA257 and SA258 are locked (S29NS128J)
– SA129 and SA130 are locked (S29NS064J)
– SA65 and SA66 are locked (S29NS032J)
– SA33 and SA34 are locked (S29NS016J)
When Acc is at VIL, all sectors are locked.
7.11 WP# Boot Sector Protection
The WP# signal will be latched at a specific time in the embedded program or erase sequence. To prevent a
write to the top two sectors, WP# must be asserted (WP#=VIL) on the last write cycle of the embedded
sequence (i.e., 4th write cycle in embedded program, 6th write cycle in embedded erase).
If using the Unlock Bypass feature: on the 2nd program cycle, after the Unlock Bypass command is written,
the WP# signal must be asserted on the 2nd cycle.
If selecting multiple sectors for erasure: The WP# protection status is latched only on the 6th write cycle of the
embedded sector erase command sequence when the first sector is selected. If additional sectors are
selected for erasure, they are subject to the WP# status that was latched on the 6th write cycle of the
command sequence.
The following hardware data protection measures prevent accidental erasure or programming, which might
otherwise be caused by spurious system level signals during VCC power-up and power-down transitions, or
from system noise.
7.11.1
Low VCC Write Inhibit
When VCC is less than VLKO, the device does not accept any write cycles. This protects data during VCC
power-up and power-down. The command register and all internal program/erase circuits are disabled, and
the device resets 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
.
7.11.2
7.11.3
Write Pulse “Glitch” Protection
Noise pulses of less than 5 ns (typical) on OE#, CE# or WE# do not initiate a write cycle.
Logical Inhibit
Write cycles are inhibited by holding any one of OE# = VIL, CE# = VIH or WE# = VIH. To initiate a write cycle,
CE# and WE# must be a logical zero while OE# is a logical one.

8. Common Flash Memory Interface (CFI)
The Common Flash Interface (CFI) specification outlines device and host system software interrogation
handshake, which allows specific vendor-specified software algorithms to be used for entire families of
devices. Software support can then be device-independent, JEDEC ID-independent, and forward- and
backward-compatible for the specified flash device families. Flash vendors can standardize their existing
interfaces for long-term compatibility.
This device enters the CFI Query mode when the system writes the CFI Query command, 98h, to address
55h any time the device is ready to read array data. The system can read CFI information at the addresses
given in Tables 8.1–8.4. 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 8.1–8.4. The
system must write the reset command to return the device to the autoselect mode.

Command Definitions
Writing specific address and data commands or sequences into the command register initiates device
operations. Table 8.16 defines the valid register command sequences. Writing incorrect address and data
values or writing them in the improper sequence resets the device to reading array data.
All addresses are latched on the rising edge of AVD#. All data is latched on the rising edge of WE#. Refer to
the AC Characteristics section for timing diagrams.
Reading Array Data
The device is automatically set to reading array data after device power-up. No commands are required to
retrieve data in asynchronous mode. Each bank is ready to read array data after completing an Embedded
Program or Embedded Erase algorithm.
After the device accepts an Erase Suspend command, the corresponding bank enters the erase-suspend-
read mode, after which the system can read data from any non-erase-suspended sector. After completing a
programming operation in the Erase Suspend mode, the system may once again read array data with the
same exception. See the Erase Suspend/Erase Resume Commands section for more information.
The system must issue the reset command to return a bank to the read (or erase-suspend-read) mode if DQ5
goes high during an active program or erase operation, or if the bank is in the autoselect mode. See the next
section, Reset Command, for more information.
See also Requirements for Asynchronous Read Operation (Non-Burst) and Requirements for Synchronous
(Burst) Read Operation in the Device Bus Operations section for more information. The Asynchronous Read
and Synchronous/Burst Read tables provide the read parameters, and Figures 14.3 and 14.5 show the
timings.
8.3
Set Configuration Register Command Sequence
The configuration register command sequence instructs the device to set a particular number of clock cycles
for the initial access in burst mode. The number of wait states that should be programmed into the device is
directly related to the clock frequency. The first two cycles of the command sequence are for unlock
purposes. On the third cycle, the system should write C0h to the address associated with the intended wait
state setting (see Table 8.9). Address bits A17–A12 determine the setting. Note that addresses Amax–A18
are shown as “0” but are actually don’t care.

Note:
1. The burst mode is set in the third cycle of the Set Wait State command sequence.
Upon power up, the device defaults to the maximum seven cycle wait state setting. It is recommended that
the wait state command sequence be written, even if the default wait state value is desired, to ensure the
device is set as expected. A hardware reset will set the wait state to the default setting.
8.3.1
Handshaking Feature
The host system should set address bits A17–A12 to “000011” for a clock frequency of 54 MHz, assuming
continuous burst is desired in both cases, for optimal burst operation.
Table 8.10 describes the typical number of clock cycles (wait states) for various conditions.

Note:
1. In the 8-, 16- and 32-word burst read modes, the address pointer does not cross 64-word boundaries when wrap around is enabled (at
address 3Fh, and at addresses offset from 3Fh by multiples of 64).
The autoselect function allows the host system to determine whether the flash device is enabled for
handshaking. See the Autoselect Command Sequence section for more information.
8.4
Sector Lock/Unlock Command Sequence
The sector lock/unlock command sequence allows the system to determine which sectors are protected from
accidental writes. When the device is first powered up, all sectors are locked. To unlock a sector, the system
must write the sector lock/unlock command sequence. Two cycles are first written: addresses are don’t care
and data is 60h. During the third cycle, the sector address (SLA) and unlock command (60h) is written, while
specifying with address A6 whether that sector should be locked (A6 = VIL) or unlocked (A6 = VIH). After the
third cycle, the system can continue to lock or unlock additional cycles, or exit the sequence by writing F0h
(reset command).
Note that the last two outermost boot sectors can be locked by taking the WP# signal to VIL. Also, if Acc is at
VIL all sectors are locked; if the Acc input is at VID, all sectors are unlocked.
8.5
Reset Command
Writing the reset command resets the banks to the read or erase-suspend-read mode. Address bits are don’t
cares for this command.
The reset command may be written between the sequence cycles in an erase command sequence before
erasing begins. This resets the bank to which the system was writing to the read mode. Once erasure begins,
however, the device ignores reset commands until the operation is complete.

37
D a t a S h e e t
The reset command may be written between the sequence cycles in a program command sequence before
programming begins. 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. Once programming begins, however, the device ignores
reset commands until the operation is complete.
The reset command may be written between the sequence cycles in an autoselect command sequence.
Once in the autoselect mode, the reset command must be written to return to the read mode. If a bank
entered the autoselect mode while in the Erase Suspend mode, writing the reset command returns that bank
to the erase-suspend-read mode.
If DQ5 goes high during a program or erase operation, writing the reset command returns the banks to the
read mode (or erase-suspend-read mode if that bank was in Erase Suspend).
8.6
Autoselect Command Sequence
The autoselect command sequence allows the host system to access the manufacturer and device codes,
and determine whether or not a sector is protected. Table 8.16 shows the address and data requirements.
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 in the other bank.
The autoselect command sequence is initiated by first writing two unlock cycles. This is followed by a third
write cycle that contains the bank address and the autoselect command. The bank then enters the autoselect
mode. The system may read at any address within the same bank any number of times without initiating
another autoselect command sequence. The following table describes the address requirements for the
various autoselect functions, and the resulting data. BA represents the bank address, and SA represent the
sector address. The device ID is read in three cycles.

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).
8.7
Program Command Sequence
Programming is a four-bus-cycle operation. The program command sequence is initiated by writing two
unlock write cycles, followed by the program set-up command. The program address and data are written
next, which in turn initiate the Embedded Program algorithm. The system is not required to provide further
controls or timings. The device automatically provides internally generated program pulses and verifies the
programmed cell margin. Table 8.16 shows the address and data requirements for the program command
sequence.
When the Embedded Program algorithm is complete, that bank then returns to the read mode and addresses
are no longer latched. The system can determine the status of the program operation by monitoring DQ7.
Refer to the Write Operation Status section for information on these status bits.
Any commands written to the device during the Embedded Program Algorithm are ignored. Note that a
hardware reset immediately terminates the program operation. The program command sequence should be
reinitiated once that bank has returned to the read mode, to ensure data integrity.
Programming is allowed in any sequence and across sector boundaries. A bit cannot be programmed from
“0” back to a “1.” Attempting to do so may cause that bank to set DQ5 = 1, or cause the DQ7 status bit to

indicate the operation was successful. However, a succeeding read will show that the data is still “0.” Only
erase operations can convert a “0” to a “1.”
Note: By default, upon every power up, the sectors will automatically be locked.
Therefore, everytime after power-up, users need to write unlock command to unlock the sectors before giving
program/erase command.
8.7.1
Unlock Bypass Command Sequence
The unlock bypass feature allows the system to 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. That bank then enters the
unlock bypass mode. A two-cycle unlock bypass program command sequence is all that is required to
program in this mode. The first cycle in this sequence contains the unlock bypass program command, A0h;
the second cycle contains the program address and data. Additional data is programmed in the same
manner. This mode dispenses with the initial two unlock cycles required in the standard program command
sequence, resulting in faster total programming time. Table 8.16 shows the requirements for the unlock
bypass command sequences.
During the unlock bypass mode, only the Unlock Bypass Program and Unlock Bypass Reset commands are
valid. To exit the unlock bypass mode, the system must issue the two-cycle unlock bypass reset command
sequence. The first cycle must contain the 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 Acc input. When the system asserts Acc 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 Acc input to
accelerate the operation.
Figure 8.1 illustrates the algorithm for the program operation. Refer to the Erase/Program Operations table in
the AC Characteristics section for parameters, and Figure 14.7 for timing diagrams.

Chip Erase Command Sequence
Chip erase is a six bus cycle operation. The chip erase command sequence is initiated by writing two unlock
cycles, followed by a set-up command. Two additional unlock write cycles are then followed by the chip erase
command, which in turn invokes the Embedded Erase algorithm. The device does not require the system to
preprogram prior to erase. The Embedded Erase algorithm automatically preprograms and verifies the entire
memory for an all zero data pattern prior to electrical erase. The system is not required to provide any
controls or timings during these operations. Table 8.16 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. 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.
Figure 8.2 illustrates the algorithm for the erase operation. Refer to the Erase/Program Operations table in
the AC Characteristics section for parameters, and Figure 14.8 section for timing diagrams.

8.9
Sector Erase Command Sequence
Sector erase is a six bus cycle operation. The sector erase command sequence is initiated by writing two
unlock cycles, followed by a set-up command. Two additional unlock cycles are written, and are then followed
by the address of the sector to be erased, and the sector erase command. Table 8.16 shows the address and
data requirements for the sector erase command sequence.
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.
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 (sector erase accept)
occurs. During the time-out 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, otherwise erasure may
begin. Any sector erase address and command following the exceeded time-out may or may not be accepted.
It is recommended that processor interrupts be disabled during this time to ensure all commands are
accepted. The interrupts can be re-enabled after the last Sector Erase command is written. Any command
other than Sector Erase or Erase Suspend during the time-out period resets that bank to the read
mode. The system must rewrite the command sequence and any additional addresses and commands.
The system can monitor DQ3 to determine if the sector erase timer has timed out (See the section on DQ3:
Sector Erase Timer.). 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 bank. The system can determine the status of the erase operation by reading DQ7in the
erasing bank. Refer to the Write Operation Status section 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 8.2 illustrates the algorithm for the erase operation. Refer to the Erase/Program Operations table in
the AC Characteristics section for parameters, and Figure 14.8 section for timing diagrams.
8.9.1
Accelerated Sector Group Erase
Under certain conditions, the device can erase sectors in parallel. This method of erasing sectors is faster
than the standard sector erase command sequence. Table 8.12 lists the sector erase groups.
The accelerated sector group erase function must not be used more than 100 times per sector. In
addition, accelerated sector group erase should be performed at room temperature (30 +/- 10°C).

Use the following procedure to perform accelerated sector group erase:
1. Unlock all sectors in a sector group to be erased using the sector lock/unlock command sequence.
All sectors that remain locked will not be erased.
2. Apply 12 V to the Acc input. This voltage must be applied at least 1 µs before executing Step 3.
3. Write 80h to any address within a sector group to be erased.
4. Write 10h to any address within a sector group to be erased.
5. Monitor status bits DQ2/DQ6 or DQ7 to determine when erasure is complete, just as in the
standard erase operation. See Write Operation Status for further details.
6. Lower Acc from 12 V to VCC
.
7. Relock sectors as required.
8.10 Erase Suspend/Erase Resume Commands
The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then read
data from, program data to, any sector not selected for erasure. The system may also lock or unlock any
sector while the erase operation is suspended. The system must not write the sector lock/unlock
command to sectors 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 or Embedded Program algorithm.

S29NS-J
S29NS-J_00_A11 February 7, 2007
D a t a S h e e t
When the Erase Suspend command is written during the sector erase operation, the device requires tESL
(erase suspend latency) 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 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.) The system may also lock or unlock any sector while in the erase-suspend-read
mode. Reading at any address within erase-suspended sectors produces status information on DQ7–DQ0.
The system can use DQ7 to determine if a sector is actively erasing or is erase-suspended. Refer to the Write
Operation Status section 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 DQ7 , just as in the standard program
operation. Refer to the Write Operation Status section for more information.
In the erase-suspend-read mode, the system can also issue the autoselect command sequence. Refer to the
Autoselect Functions and Autoselect Command Sequence sections 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.

9. Write Operation Status
The device provides several bits to determine the status of a program or erase operation: DQ2, DQ3, DQ5
and DQ7. Table 9.2 and the following subsections describe the function of these bits. DQ7 a method for
determining whether a program or erase operation is complete or in progress.
9.1
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 a bank is in Erase Suspend. Data# Polling is valid after the rising
edge of the final WE# pulse in the command sequence.
During the Embedded Program algorithm, the device outputs on DQ7 the complement of the datum
programmed to DQ7. This DQ7 status also applies to programming during Erase Suspend. When the
Embedded Program algorithm is complete, the device outputs the datum programmed to DQ7. The system
must provide the program address to read valid status information on DQ7. If a program address falls within a
protected sector, Data# Polling on DQ7 is active for approximately 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 (all sectors protected toggle time), 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–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
the status or valid data. Even if the device has completed the program or erase operation and DQ7 has valid
data, the data outputs on DQ6–DQ0 may be still invalid. Valid data on DQ7–DQ0 will appear on successive
read cycles.
Table 9.2 shows the outputs for Data# Polling on DQ7. Figure 9.1 shows the Data# Polling algorithm.
Figure 14.10 in the AC Characteristics section shows the Data# Polling timing diagram.

1. VA = Valid Address for programming. During a sector erase operation, a valid address is any sector address within the sector being
erased. During chip erase, a valid address is any non-protected sector address.
2. DQ7 should be rechecked even if DQ5 = “1” because DQ7 may change simultaneously with DQ5.
9.2
RDY: Ready
The RDY pin is a dedicated status output that indicates valid output data on A/DQ15–A/DQ0 during burst
(synchronous) reads. When RDY is asserted (RDY = VOH), the output data is valid and can be read. When
RDY is de-asserted (RDY = VOL), the system should wait until RDY is re-asserted before expecting the next
word of data.
In synchronous (burst) mode with CE# = OE# = VIL, RDY is de-asserted under the following conditions:
during the initial access; after crossing the internal boundary between addresses 3Eh and 3Fh (and
addresses offset from these by a multiple of 64); and when the clock frequency is less than 6 MHz (in which
case RDY is de-asserted every third clock cycle). The RDY pin will also switch during status reads when a
clock signal drives the CLK input. In addition, RDY = VOH when CE# = VIL and OE# = VIH, and RDY is Hi-Z
when CE# = VIH.
In asynchronous (non-burst) mode, the RDY pin does not indicate valid or invalid output data. Instead, RDY =
VOH when CE# = VIL, and RDY is Hi-Z when CE# = VIH.

9.3
DQ6: Toggle Bit I
Toggle Bit I on DQ6 indicates whether an Embedded Program or Erase algorithm is in progress or complete,
or whether the device has entered the Erase Suspend mode. Toggle Bit I may be read at any address 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. Note that OE# must be low during toggle bit status reads. 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, 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 erase-
suspended. When the device is actively erasing (that is, the Embedded Erase algorithm is in progress), DQ6
toggles. When the device enters the Erase Suspend mode, DQ6 stops 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 after tPSP 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: (toggle bit flowchart), DQ6: Toggle Bit I (description),
Figure 14.11 (toggle bit timing diagram), and Table 9.1 (compares DQ2 and DQ6).

1. The system should recheck the toggle bit even if DQ5 = “1” because the toggle bit may stop toggling as DQ5 changes to “1.” See the

9.4
DQ2: Toggle Bit II
The “Toggle Bit II” on DQ2, when used with DQ6, indicates whether a particular sector is actively erasing (that
is, the Embedded Erase algorithm is in progress), or whether that sector is erase-suspended. Toggle Bit II is
valid after the rising edge of the final WE# pulse in the command sequence.
DQ2 toggles when the system reads at addresses within those sectors that have been selected for erasure.
Note that OE# must be low during toggle bit status reads. 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 9.2 to compare outputs for DQ2 and DQ6.
See the following for additional information: (toggle bit flowchart), DQ6: Toggle Bit I (description),

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 erase operation. The
system can read array data on DQ7–DQ0 on the following read cycle.
However, if after the initial two read cycles, the system determines that the toggle bit is still toggling, the
system also should note whether the value of DQ5 is high (see the section on DQ5). If it is, the system should
then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as
DQ5 went high. If the toggle bit is no longer toggling, the device has successfully completed the program or
erase operation. If it is still toggling, the device did not completed the operation successfully, and the system
must write the reset command to return to reading array data.
The remaining scenario is that the system initially determines that the toggle bit is toggling and DQ5 has not
gone high. The system may continue to monitor the toggle bit and DQ5 through successive read cycles,
determining the status as described in the previous paragraph. Alternatively, it may choose to perform other
system tasks. In this case, the system must start at the beginning of the algorithm when it returns to
determine the status of the operation.

9.7
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
erase-suspend-read mode if a bank was previously in the erase-suspend-program mode).
DQ3: Sector Erase Timer
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
also the Sector Erase Command Sequence section.
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 will accept additional sector erase commands.

D a t a S h e e t
To ensure the command has been accepted, the system software should check the status of DQ3 prior to and
following each subsequent sector erase command. If DQ3 is high on the second status check, the last
command might not have been accepted.
Table 9.2 shows the status of DQ3 relative to the other status bits.

Notes
1. DQ5 switches to ‘1’ when an Embedded Program or Embedded Erase operation has exceeded the maximum timing limits. Refer to the
section on DQ5 for more information.
2. DQ7 and DQ2 require a valid address when reading status information. Refer to the appropriate subsection for further details.
3. When reading write operation status bits, the system must always provide the bank address where the Embedded Algorithm is in
progress. The device outputs array data if the system addresses a non-busy bank.
4. The system may read either asynchronously or synchronously (burst) while in erase suspend. RDY will function exactly as in non-erase-
suspended mode.

Notes
1. Typical program and erase times assume the following conditions: 25°C, 1.8 V V , 100,000 cycles. Additionally, programming typicals
CC
assume checkerboard pattern.
2. Under worst case conditions of 90°C, V = 1.7 V, 1,000,000 cycles.
CC
3. The typical chip programming time is considerably less than the maximum chip programming time listed.
4. In the pre-programming step of the Embedded Erase algorithm, all words are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table 8.16 for
further information on command definitions.
6. The device has a minimum erase and program cycle endurance of 100,000 cycles.
