GENERAL PRODUCT DESCRIPTION
The ES29LV160 is completely compatible with the
JEDEC standard command set of single power supply Flash. Commands are written to the internal
command register using standard write timings of
microprocessor and data can be read out from the
cell array in the device with the same way as used in
other EPROM or flash devices.
The ES29LV160 is a 16 megabit, 3.0 volt-only flash
memory device, organized as 2M x 8 bits (Byte
mode) or 1M x 16 bits (Word mode) which is configurable by BYTE#. Four boot sectors and thirty one
main sectors are provided : 16Kbytes x 1, 8Kbytes
x 2, 32Kbytes x 1 and 64Kbytes x 31. The device is
manufactured with ESI’s proprietary, high performance and highly reliable 0.18um CMOS flash
technology. The device can be programmed or
erased in-system with standard 3.0 Volt Vcc supply
( 2.7V-3.6V) and can also be programmed in standard EPROM programmers. The device offers minimum endurance of 100,000 program/erase cycles
and more than 10 years of data retention.
The ES29LV160 offers access time as fast as 70ns
or 90ns, allowing operation of high-speed microprocessors without wait states. Three separate control
pins are provided to eliminate bus contention : chip
enable (CE#), write enable (WE#) and output
enable (OE#).
All program and erase operation are automatically
and internally performed and controlled by embedded program/erase algorithms built in the device.
The device automatically generates and times the
necessary high-voltage pulses to be applied to the
cells, performs the verification, and counts the number of sequences. Some status bits (DQ7, DQ6 and
DQ5) read by data# polling or toggling between
consecutive read cycles provide to the users the
internal status of program/erase operation: whether
it is successfully done or still being progressed.

DEVICE BUS OPERATIONS
Several device operational modes are provided in
the ES29LV160 device. Commands are used to initiate the device operations. They are latched and
stored into internal registers with the address and
data information needed to execute the device
operation.
on the device address inputs produce valid data on
the device data outputs. The device stays at the read
mode until another operation is activated by writing
commands into the internal command register. Refer
to the AC read cycle timing diagrams for further
details ( Fig. 16 ).
The available device operational modes are listed
in Table 1 with the required inputs, controls, and the
resulting outputs. Each operational mode is
described in further detail in the following subsections.
Word/Byte Mode Configuration ( BYTE# )
The device data output can be configured by BYTE#
into one of two modes : word and byte modes. If the
BYTE# pin is set at logic ‘1’, the device is configured
in word mode, DQ0 - DQ15 are active and controlled
by CE# and OE#. If the BYTE# pin is set at logic ‘0’,
the device is configured in byte mode, and only data
I/O pins DQ0 - DQ7 are active and controlled by CE#
and OE#. The data I/O pins DQ8 - DQ14 are tristated, and the DQ15 pin is used as an input for the
LSB (A-1) address.
Read
The internal state of the device is set for the read
mode and the device is ready for reading array data
upon device power-up, or after a hardware reset. To
read the stored data from the cell array of the
device, CE# and OE# pins should be driven to VIL
while WE# pin remains at VIH. CE# is the power
control and selects the device. OE# is the output
control and gates array data to the output pins.
Standby Mode
When the device is not selected or activated in a
system, it needs to stay at the standby mode, in
which current consumption is greatly reduced with
outputs in the high impedance state.
Word or byte mode of output data is determined by
the BYTE# pin. No additional command is needed
in this mode to obtain array data. Standard microprocessor read cycles that assert valid addresses

set-up cycle and the last cycle with the program data
and addresses. In this mode, two unlock cycles are
saved ( or bypassed ).
The device enters the CMOS standby mode when
CE# and RESET# pins are both held at Vcc+0.3V.
(Note that this is a more restricted voltage range
than VIH.) If CE# and RESET# are held at VIH, but
not within Vcc+0.3V, the device will be still in the
standby mode, but the standby current will be
greater than the CMOS standby current (0.2uA typically). When the device is in the standby mode, only
standard access time (tCE) is required for read
access, before it is ready for read data. And even if
the device is deselected by CE# pin during erase or
programming operation, the device draws active current until the operation is completely done. While the
device stays in the standby mode, the output is
placed in the high impedance state, independent of
the OE# input.
Sector Addresses
The entire memory space of cell array is divided into
a many of small sectors: 16Kbytes x 1, 8Kbytes x 2,
32Kbytes x 1 and 64Kbytes x 31 main sectors. In
erase operation, a single sector, multiple sectors, or
the entire device (chip erase) can be selected for
erase. The address space that each sector occupies
is shown in detail in the Table 3-4.
Autoselect Mode
Flash memories are intended for use in applications
where the local CPU alters memory contents. In
such applications, manufacturer and device identification (ID) codes must be accessible while the
device resides in the target system ( the so called
“in-system program”). On the other hand, signature
codes have been typically accessed by raising A9
pin to a high voltage in PROM programmers. However, multiplexing high voltage onto address lines is
not the generally desired system design practice.
Therefore, in the ES29LV160 device an autoselect
command is provided to allow the system to access
the signature codes without any high voltage. The
conventional A9 high-voltage method used in the
PROM programers for signature codes are still supported in this device.
If the system writes the autoselect command
sequence, the device enters the Autoselect mode.
The system can then read some useful codes such
as manufacturer and device ID from the internal registers on DQ7 - DQ0. Standard read cycle timings
apply in this mode. In the Autoselect mode, the following three informations can be accessed through
either autoselect command method or A9 high-voltage autoselect method. Refer to the Table 2.
The device can enter the deep power-down mode
where current consumption is greatly reduced down
to less than 0.2uA typically by the following three
ways:
- CMOS standby ( CE#, RESET# = Vcc + 0.3V )
- During the device reset ( RESET# = Vss + 0.3V )
- In Autosleep Mode ( after tACC + 30ns )
Refer to the CMOS DC characteristics Table11 for
further current specification.
Autosleep Mode
The device automatically enters a deep power-down
mode called the autosleep mode when addresses
remain stable for tACC+30ns. In this mode, current
consumption is greatly reduced ( less than 0.2uA
typical ), regardless of CE#, WE# and OE# control
signals.
Writing Commands
To write a command or command sequences to initiate some operations such as program or erase, the
system must drive WE# and CE# to VIL, and OE# to
VIH. For program operations, the BYTE# pin determines whether the device accepts program data in
bytes or words. Refer to “BYTE# timings for Write
Operations” in the Fig. 19 for more information.
- Manufacturer ID
- Device ID
- Sector protection verify
Hardware Device Reset ( RESET# )
The RESET# pin provides a hardware method of
resetting the device to read array data. When the
RESET# pin is driven low for at least a period of tRP ,
Unlock Bypass Mode
To reduce more the programming time, an unlockbypass mode is provided. Once the device enters
this mode, only two write cycles are required to initiate the programming operation instead of four
cycles in the normal program command sequences
which are composed of two unlock cycles, program

the device immediately terminates any operation in
progress, tristates all output pins, and ignores all
read/write commands for the duration of the
RESET# pulse The device also resets the internal
state machine to reading array data. The operation
that was interrupted should be reinitiated once after
the device is ready to accept another command
sequence, to ensure data integrity.
Sector protection can be implemented via two
methods.
- In-system protection
- A9 High-voltage protection
To check whether the sector protection was successfully executed or not, another operation called
“protect verification” needs to be performed after
the protection operation on a sector. All protection
and protect verifications provided in the device are
summarized in detail at the Table 1.
CMOS Standby during Device Reset
Current is reduced for the duration of the RESET#
pulse. When RESET# is held at Vss + 0.3V, the
device draws the greatly reduced CMOS standby
current ( ICC4 ). If RESET# is held at VIL but not
within Vss+0.3V, the standby current will be greater.
In-System Protection
“In-system protection”, the primary method,
requires VID (11.5V~12.5V) on the RESET# with
A6=0, A1=1, and A0=0. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor
bus cycle timing. Refer to Fig. 26 for timing diagram
and Fig. 2 for the protection algorithm.
RY/BY# and Terminating Operations
If RESET# is asserted during a program or erase
operation, the RY/BY# pin remains a “0” (busy) until
the internal reset operation is completed, which
requires a time of tREADY (during Embedded Algorithms). The system can thus monitor RY/BY# to
determine whether the reset operation is completed.
If RESET# is asserted when a program or erase
operation is not executing (RY/BY# pin is “1”), the
reset operation is completed within a time of tREADY
(not during Embedded Algorithms). The system can
read data after the RESET# pin returns to VIH, which
requires a time of tRH.
A9 High-Voltage Protection
“High-voltage protection”, the alternate method
intended only for programming equipment, must
force VID (11.5~12.5V) on address pin A9 and control pin OE# with A6=0, A1=1 and A0=0. Refer to
Fig. 28 for timing diagram and Fig. 4 for the protection algorithm.
RESET# tied to the System Reset
SECTOR UNPROTECTION
The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the
Flash memory, enabling the system to read the bootup firmware from the Flash memory.Refer to the AC
Characteristics tables for RESET# parameters and
to Fig. 17 for the timing diagram.
The previously protected sectors must be unprotected before modifying any data in the sectors.
The sector unprotection algorithm unprotects all
sectors in parallel. All unprotected sectors must first
be protected prior to the first sector unprotection
write cycle to avoid any over-erase due to the intrinsic erase characteristics of the protection cell. After
the unprotection operation, all previously protected
sectors will need to be individually re-protected.
Standard microprocessor bus cycle timings are
used in the unprotection and unprotect verification
operations. Three unprotect methods are provided
in the ES29LV160 device. All unprotection and
unprotect verification cycles are summarized in
detail at the Table 1.
SECTOR PROTECTION
The ES29LV160 features hardware sector protection. In the device, sector protection is performed on
the sector previously defined in the Table 3-4. Once
after a sector is protected, any program or erase
operation is not allowed in the protected sector. The
previously protected sectors must be unprotected by
one of the unprotect methods provided here before
changing data in those sectors.

Rev. 1C Jan 5 , 2006

In-System Unprotection
The command register and all internal program/
erase circuits are disabled, and the device resets to
the read mode. Subsequent writes are ignored until
Vcc is greater than VLKO. The system must provide
proper signals to the control pins to prevent unintentional writes when Vcc is greater than VLKO.
“In-system unprotection”, the primary method,
requires VID (11.5V~12.5V) on the RESET# with
A6=1, A1=1, and A0=0. This method can be implemented either in-system or via programming equipment. This method uses standard microprocessor
bus cycle timing. Refer to Fig. 26 for timing diagram
and Fig. 3 for the unprotection algorithm.
Write Pulse “Glitch” Protection
Noise pulses of less than 5ns (typical) on OE#, CE#
or WE# do not initiate a write cycle.
A9 High-Voltage Unprotection
“High-voltage unprotection”, the alternate method
intended only for programming equipment, must
force VID (11.5~12.5V) on address pin A9 and control pin OE# with A6=1, A1=1 and A0=0. Refer to
Fig. 29 for timing diagram and Fig. 5 for the unprotection algorithm.
Logical inhibit
Temporary Sector Unprotect
Power-up Write Inhibit
This feature allows temporary unprotection of previously protected sectors to change data in-system.
The Sector Unprotect mode is activated by setting
the RESET# pin to VID (11.5V-12.5V). During this
mode, formerly protected sectors can be programmed or erased by selecting the sector
addresses. Once VID is removed from the RESET#
pin, all the previously protected sectors are protected again. Fig. 1 shows the algorithm, and Fig. 25
shows the timing diagrams for this feature.
If WE#=CE#=VIL and OE#=VIH during power up,
the device does not accept any commands on the
rising edge of WE#. The internal state machine is
automatically reset to the read mode on power-up.
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.

RESET# = VID
(Note 1)
HARDWARE DATA PROTECTION
The ES29LV160 device provides some protection
measures against accidental erasure or programming caused by spurious system level signals that
may exist during power transition. During power-up,
all internal registers and latches in the device are
cleared and the device automatically resets to the
read mode. In addition, with its internal state
machine built-in the device, any alteration of the
memory contents or any initiation of new operationcan only occur after successful completion of specific command sequences. And several features are
incorporated to prevent inadvertent write cycles
resulting from Vcc power-up and power-down transition or system noise.

When Vcc is less than VLKO, the device does not
accept any write cycles. This protects data during
Vcc power-up and power-down.

This device enters the CFI Query mode when the
system writes the CFI query command, 98h, to
address 55h in word mode (or address AAh in byte
mode), any time the device is ready to read array
data. The system can read CFI information at the
addresses given in Tables 5-8. To terminate reading
CFI data, the system must write the reset command.The CFI query command can be written to the
system when the device is in the autoselect mode
or the erase-suspend-read mode. The device
enters the CFI query mode, and the system can read
CFI data at the addresses given in Tables 5-8.
When the reset command is written, the device
returns respectively to the read mode or erase-suspend-read mode.
Common Flash Memory
Interface (CFI)
CFI is supported in the ES29LV160 device. 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.

COMMAND DEFINITIONS
the Device Bus Operations section for more information.The Read-Only Operations table provides the
read parameters, and Fig. 16 shows the timing diagram
Writing specific address and data commands or
sequences into the command register initiates
device operations. Table 9 defines the valid register
command sequences. Note that writing incorrect
address and data values or writing them in the
improper sequence may place the device in an
unknown state. A reset command is required to
return the device to normal operation.
RESET COMMAND
Writing the reset command resets the device to the
read or erase-suspend-read mode. Address bits are
don’t cares for this command.
All addresses are latched on the falling edge of WE#
or CE#, whichever happens later. All data is latched
on the rising edge of WE# or CE#, whichever happens first. Refer to the AC Characteristics section for
timing diagrams.
The reset command may be written between the
sequence cycles in an erase command sequence
before erasing begins. This resets the device to
which the system was writing to the read mode.
Once erasure begins, however, the device ignores
reset commands until the operation is complete.
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required
to retrieve data. The device is ready to read array
data after completing an Embedded Program or
Embedded Erase algorithm.
The reset command may be written between the
sequence cycles in a program command sequence
before programming begins. This resets the device
to which the system was writing to the read mode. If
the program command sequence is written to a sector that is in the Erase Suspend mode, writing the
reset command returns the device to the erase-suspend-read mode. Once programming begins, however, the device ignores reset commands until the
operation is complete.
After the device accepts an Erase Suspend command, the device 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 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 the device entered the autoselect mode
while in the Erase Suspend mode, writing the reset
command returns the device to the erase-suspendread mode.
The system must issue the reset command to return
the device to the read (or erase-suspend-read)
mode if DQ5 goes high during an active program or
erase operation, or if the device is in the autoselect
mode. See the next section, Reset Command, for
more information.
If DQ5 goes high during a program or erase operation, writing the reset command returns the device to
the read mode (or erase-suspend-read mode if the
device was in Erase-Suspend).

AUTOSELECT COMMAND
BYTE / WORD PROGRAM
The autoselect command sequence allows the host
system to access the manufacturer and device
codes, and determine whether or not a sector is
protected, including information about factorylocked or customer lockable version.
The system may program the device by word or
byte, depending on the state of the BYTE# pin.
Programming is a four-bus-cycle operation. The
program command sequence is initiated by writing
two unlock write cycles, followed by the program
set-up command. The program address and data
are written next, which in turn initiate the Embedded
Program algorithm. The system is not required to
provide further controls or timings. The device automatically provides internally generated program
pulses and verifies the programmed cell margin.
Table 9 shows the address and data requirements
for the byte program command sequence. Note that
the autoselect and CFI modes are unavailable
while a programming operation is in progress.

Table 9 shows the address and data requirements.
This method is an alternative to “A9 high-voltage
method” shown in Table 2, which is intended for
PROM programmers and requires VID on address
pin A9. The autoselect command sequence may be
written to an address within sector that is either in
the read mode or erase-suspend-read mode. The
auto-select command may not be written while the
device is actively programming or erasing. The
autoselect command sequence is initiated by first
writing two unlock cycles. This is followed by a third
write cycle that contains the autoselect command.
The device then enters the autoselect mode. The
system may read at any address any number of
times without initiating another autoselect command sequence.

Program Status Bits : DQ7, DQ6 or RY/BY#
During the unlock-bypass mode, only the unlockbypass program and unlock-bypass reset commands are valid. To exit the unlock-bypass mode,
the system must issue the two-cycle unlock-bypass
reset command sequence. The first cycle must contain the data 90h. The second cycle need to only
contain the data 00h. The device then returns to the
read mode.
When the Embedded Program algorithm is complete, the device then returns to the read mode and
addresses are no longer latched. The system can
determine the status of the program operation by
using DQ7, DQ6, or RY/BY#. Refer to the Write
Operation Status section Table 10 for information on
these status bits.

Any Commands Ignored during Programming Operation
CHIP ERASE COMMAND
Any commands written to the device during the
Embedded Program algorithm are ignored. Note that
a hardware reset can immediately terminates the
program operation. The program command
sequence should be reinitiated once the device has
returned to the read mode, to ensure data integrity.
To erase the entire memory, a chip erase command
is used. This command 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 chip
erase command erases the entire memory including all other sectors except the protected sectors,
but the internal erase operation is performed on a
single sector base.
Programming from “0” back to “1”
Programming is allowed in any sequence and
across sector boundaries. But a bit cannot be programmed from “0” back to a ”1”. Attempting to do so
may cause the device to set DQ5 = 1, or cause the
DQ7 and DQ6 status bits 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”
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 9 shows the address and data
requirements for the chip erase command
sequence. Note that the autoselect, and CFI modes
are unavailable while an erase operation is in
progress
Unlock Bypass
In the ES29LV160 device, an unlock bypass program mode is provided for faster programming operation. In this mode, two cycles of program command
sequences can be saved. To enter this mode, an
unlock bypass enter command should be first written
to the system. The unlock bypass enter 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 program 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 set-up 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 9 shows the requirements for the
command sequence.
Erase Status Bits : DQ7, DQ6, DQ2, or RY/

When the Embedded Erase algorithm is complete,
the device returns to the read mode and addresses
are no longer latched. The system can determine
the status of the erase operation by using DQ7,
DQ6, DQ2, or RY/BY#. Refer to the Write Operation Status section Table 10 for information on these
status bits.

Status Bits : DQ7,DQ6,DQ2, or RY/BY#
When the Sector Erase Embedded Erase algorithm
is complete, the device 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 nonerasing sector. The system can determine the status of the erase operation by reading
DQ7,DQ6,DQ2, or RY/BY# in the erasing sector.
Refer to the Write Operation Status section Table
10 for information on these status bits.
SECTOR ERASE COMMAND
By using a sector erase command, a single sector or
multiple sectors can be erased. The sector erase
command 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 9 shows the
address and data requirements for the sector erase
command sequence. Note that the autoselect, and
CFI modes are unavailable while an erase operation
is in progress.
Valid Command during Sector Erase
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

After the command sequence is written, a sector
erase time-out of 50us 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 50 us, otherwise the last address and command may not be accepted, and erasure may begin.
It is recommended that processor interrupts be disabled during this time to ensure all commands are
accepted. The interrupts can be re-enabled after the
last Sector Erase command is written. The system
can monitor DQ3 to determine if the sector erase

After an erase-suspended program operation is

the program operation using the DQ7 or DQ6 status
bits, just as in the standard Byte Program operation.
Refer to the Write Operation Status section for more
information.

tables in the AC Characteristics section for parameters, and Fig. 21 section for timing diagrams.
Autoselect during Erase-Suspend- Read
Mode
ERASE SUSPEND/ERASE RESUME
In the erase-suspend-read mode, the system can
also issue the autoselected command sequence.
Refer to the Autoselect Mode and Autoselect Command Sequence section for details (Table 9).
An erase operation is a long-time operation so that
two useful commands are provided in the
ES29LV160 device Erase Suspend and Erase
Resume Commands. Through the two commands,
erase operation can be suspended for a while and
the suspended operation can be resumed later when
it is required. While the erase is suspended, read or
program operations can be performed by the system.
Erase Resume Command
To resume the sector erase operation, the system
must write the Erase Resume command. Further
writes of the Resume command are ignored.
Another Erase Suspend command can be written
after the chip has resumed erasing.
Erase Suspend Command, (B0h)
The Erase Suspend command, B0h, allows the system to interrupt a sector erase operation and then
read data from, or program data to, any sector not
selected for erasure. This command is valid only during the sector erase operation, including the 50us
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. When the Erase Suspend
command is written during the sector erase operation, the device requires a maximum of 20us to suspend the erase operation. However, when the Erase
Suspend command is written during the sector erase
time-out, the device immediately terminates the timeout period and suspends the erase operation.
Read and Program during Erase-SuspendRead Mode
After the erase operation has been suspended, the
device enters the erase-suspend-read mode. The
system can read data from or program data to any
sector not selected for erasure. (The device “erase
suspends” all sectors selected for erasure.)
Reading at any address within erase-suspended sectors produces status information on DQ7-DQ0. The
system can use DQ7, or DQ6 and DQ2 together, to
determine if a sector is actively erasing or is erasesuspended. Refer to the Write Operation Status section for information on these status bits (Table 10).

WRITE OPERATION STATUS
Erase algorithm is complete, or if the device enters
the Erase Suspend mode, Data# polling produces a
“1” on DQ7. The system must provide an address
within any of the sectors selected for erasure to read
valid status information on DQ7.
In the ES29LV160 device, several bits are provided
to determine the status of a program or erase operation: DQ2, DQ3, DQ5, DQ6, DQ7 and RY/BY#.
Table 10 and the following subsections describe the
function of these bits. DQ7 and DQ6 each offer a
method for determining whether a program or erase
operation is complete or in progress. The device
also provides a hardware-based output signal, RY/
BY#, to determine whether an Embedded Program
or Erase operation is in progress or has been completed.
Erase on the Protected Sectors
After an erase command sequence is written, if all
sectors selected for erasing are protected, Data#
Polling on DQ7 is active for approximately 1.8us,
then the device returns to the read mode. If not all
selected sectors are protected, the Embedded Erase
algorithm erases the unprotected sectors, and
ignores the selected sectors that are protected. However, if the system reads DQ7 at an address within a
protected sector, the status may not be valid.
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
device is in Erase Suspend. Data# Polling is valid
after the rising edge of the final WE# pulse in the
command sequence.
Data# Polling Algorithm
Just prior to the completion of an Embedded
Program or Ease operation, DQ7 may change
asynchronously with DQ0-DQ6 while Output
Enable(OE#) is asserted low. That is, this 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 DQ0-DQ7 will appear on
successive read cycles.
During Programming
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
250ns, then the device returns to the read mode.
Table 10 shows the outputs for Data# Polling on
DQ7. Fig. 9 shows the Data# Polling algorithm. Fig.
22 in the AC Characteristics section shows the
Data# Polling timing diagram.

During the Embedded Erase algorithm, Data# Polling produces a “0” on DQ7. When the Embedded

Erase Suspend mode. Toggle Bit I may be read at
any address, and is valid after the rising edge of the
final WE# pulse in the command sequence ( prior to
the program or erase operation), and during the sector erase time-out. During an Embedded Program or
Erase algorithm operation, successive read cycles to
any address cause DQ6 to toggle. The system may
use either OE# or CE# to control the read cycles.
When the operation is complete, DQ6 stops toggling.

The system can use DQ6 and DQ2 together to

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). DQ6 also toggles

toggling once the Embedded Program algorithm is

Figure 9. Data# Polling Algorithm
Toggling on the Protected Sectors
RY/BY# ( READY/BUSY# )
After an erase command sequence is written, if all
sectors selected for erasing are protected, DQ6 toggles for approximately 1.8us, 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. If a program address falls within a
protected sector, DQ6 toggles for approximately
250ns after the program command sequence is written, then returns to reading array data.
The RY/BY# is a dedicated, open-drain output pin
which indicates whether an Embedded Algorithm is
in progress or complete. The RY/BY# status is valid
after the rising edge of the final WE# pulse in the
command sequence. Since RY/BY# is an opendrain output, several RY/BY# pins can be tied
together in parallel with a pull-up resistor to Vcc. If
the output is low (Busy), the device is actively erasing or programming. (This includes programming in
the Erase Suspend mode.) If the output is high
(Ready), the device is in the read mode, the
standby mode, or in the erase-suspend-read mode.
Table 10 shows the outputs for RY/BY#.
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
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

toggles when the system reads at addresses within
those sectors that have been selected for erasure.
(The system may use either OE# or CE# to control
the read cycles.) But DQ2 cannot distinguish
whether the sector is actively erasing or is erasesuspended. 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 10 to compare outputs for DQ2 and DQ6. Fig.
10 shows the toggle bit algorithm in flowchart form,
and the section “DQ2: Toggle Bit II” explains the
algorithm. See also the DQ6: Toggle Bit I subsection. Fig. 23 shows the toggle bit timing diagram.

Refer to Fig. 10 for the following discussion. Whenever the system initially begins reading toggle bit
status, it must read DQ7-DQ0 at least twice in a row
to determine whether a toggle bit is toggling. Typically, the system would note and store the value of
the toggle bit after the first read. After the second
read, the system would compare the new value of
the toggle bit with the first. If the toggle bit is not
toggling, the device has completed the program or
erase operation. The system can read array data
on DQ7-DQ0 on the following read cycle. However,
if after the initial two read cycles, the system determines that the toggle bit is still toggling, the system
also should note whether the value of DQ5 is high
(see the section on DQ5). If it is, the system should
then determine again whether the toggle bit is toggling, since the toggle bit may have stopped toggling just as DQ5 went high. If the toggle bit is no
longer toggling, the device has successfully completed the program or erase operation. If it is still
toggling, the device did not 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, this system must start at the beginning of the algorithm
when it returns to determine the status of the operation (top of Fig. 10).

DQ5 ( EXCEEDED TIMING LIMITS )
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
50us, 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 erasure operation is complete. If DQ3 is “0”, the device will accept additional
sector erase commands. To ensure the command
has been accepted, the system software should
check the status of DQ3 prior to and following each
subsequent sector erase command. If DQ3 is high
on the second status check, the last command might
not have been accepted. In Table 10, DQ3 status
operation is well defined and summarized with other
status bits, DQ7, DQ6, DQ5, and DQ2.
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.
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 time
does not apply to the chip erase command.)

transitions, input or I/O pins may overshoot Vss to -2.0V for periods of up to 20ns. Maximum DC voltage on input or I/O pins is
Vcc+0.5V. See Fig. 11. During voltage transition, input or I/O pins
may overshoot to Vcc+2.0V for periods up to 20ns. See Fig. 11.

2. Minimum DC input voltage on pins A9, OE# and RESET# is -0.5V
. During voltage transitions, A9, OE# and RESET# may overshoot
Vss to -2.0V for periods of up to 20ns. See Fig. 11. Maximum DC
input voltage on pin A9 is +12.5V which may overshoot to +14.0V
for periods up to 20ns.

Notes:
1. Typical program and erase times assume the following conditions: 25oC, 3.0V Vcc, 10,000 cycles. Additionally, programming
typicals assume checkerboard pattern.
2. Under worst case conditions of 90oC, Vcc = 2.7V, 100,000 cycles.
3. The typical chip programming time is considerably less than the maximum chip programming time listed, since most bytes
program faster than the maximum program times listed.
4. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two-or-four-bus-cycle sequence for the program command. See
Table 9 for further information on command definitions.
6. The device has a minimum erase and program cycle endurance of 100,000 cycles.

dambar protrusion shall be 0.08mm (0.0031”) total in excess
of b dimension at max. material condition. Minimum space
between protrusion and an adjacent lead to be 0.07mm
(0.0028”).
7. These dimensions apply to the flat section of the lead between
0.10mm (0.0039”) and 0.25mm (0.0098”) from the lead tip.
8. Lead coplanarity shall be within 0.10mm (0.004”) as measured
from the seating plane.
9. Dimension “e” is measured at the centerline of the leads.
