GENERAL PRODUCT DESCRIPTION
The ES29DL320 is a 32 megabit, 3.0 volt-only flash
memory device, organized as 4M x 8 bits (Byte
mode) or 2M x 16 bits (Word mode) which is configurable by BYTE#. Eight boot sectors and sixty three
main sectors with uniform size are provided : 8K
bytes x 8 and 64K bytes x 63. 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 20 years of data retention.
Therefore, this lock indicator bit (DQ7) can be properly used to avoid that any customer-lockable part is
used to replace a factory-locked part. The extra
security sector is an extra memory space for customers when it is used as a customer-lockable version. So, it can be read and written like any other
sectors. But it should be noted that the number of E/
W(Erase and Write) cycles is limited to 300 times
(maximum) only in the Security Sector.
Special services such as ESN and factory-locked
are available to customers ( ESI’s Special-Code
service ) The ES29DL320 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 ES29DL320 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#).
Simultaneous Read / Write Operation
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.
The simultaneous read / write architecture provides
simultaneous operation by dividing the memory
space into multi-bank. Sector addresses are fixed,
system software can be used to form user-defined
bank groups.
During an erase / program operation, any of the nonbusy banks may be read from. Note that only two
banks can operate simultaneously. The device
allows a host system to program or erase in one
bank, then immediately and simultaneously read
from the other bank, with zero latency. This releases
the system from waiting for the completion of program or erase operations.
Extra Security Sector of 256 bytes
In the device, an extra security sector of 256 bytes
is provided to customers. This extra sector can be
used for various purposes such as storing ESN
(Electronic Serial Number) or customer’s security
codes. Once after the extra sector is written, it can
be permanently locked by the device manufacturer(
factory-locked) or a customer(customer-lockble).
At the same time, a lock indicator bit (DQ7) is permanently set to a 1 if the part is factory- locked, or
set to 0 if it is customer-lockable.
ES29DL320
The ES29DL320 can be organized as either a top or
bottom boot sector configuration.

DEVICE BUS OPERATIONS
Simultaneous Read/Write Operation
Several device operational modes are provided in
the ES29DL320 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.
This device is capable of reading data from one bank
of memory while programming or erasing in the
other bank 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 33 shows how read and write
cycles may be initiated for simultaneous operation
with zero latency. Refer to the CMOS DC characteristics Table11 for further current specification.
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# )
Read
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.
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.
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
on the device address inputs produce valid data on
the device data outputs. Each bank 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. 18 ).
ES29DL320
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.

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 (15uA 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: 8kbytes x 8 boot sectors and 64Kbytes x 63 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.
Accelerated Program 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 15uA typical ), regardless of CE#, WE# and OE# control signals.
The device offers accelerated program operations
through the ACC function. This is one of two functions provided by the WP#/ACC pin. This function
is primarily intended to allow faster manufacturing
throughput at the factory. If the system asserts VHH
(8.5~9.5V) on this pin, the device automatically
enters the previously mentioned Unlock Bypass
mode, temporarily unprotects any protected sectors, and uses the higher voltage on the pin to
reduce the time required for program operations.
Only two-cycle program command sequences are
required because the unlock bypass mode is automatically activated in this acceleration mode. The
device returns to the normal operation when VHH is
removed from the WP#/ACC pin. It should be
noted that the WP#/ACC pin must not be at VHH for
operations other than accelerated programming, or
device damage may result. In addition, the WP#/
ACC pin must not be left floating or unconnected;
inconsistent or undesired behavior of the device
may result.
Writing Commands
Autoselect Mode
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. 21 for more information.
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 ES29DL320
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.
The device can enter the deep power-down mode
where current consumption is greatly reduced down
to less than 15uA 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
Unlock Bypass Mode
To reduce more the programming time, an unlockbypass mode is provided. Once a bank 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 set-up

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 four informations can be accessed through
either autoselect command method or A9 high-voltage autoselect method. Refer to the Table 2.
Flash memory, enabling the system to read the
boot-up firmware from the Flash memory. Refer to
the AC Characteristics tables for RESET# parameters and to Fig. 19 for the timing diagram.
SECTOR GROUP PROTECTION
The ES29DL320 features hardware sector group
protection. A sector group consists of two or more
adjacent sectors that are protected or unprotected
at the same time. In the device, sector protection is
performed on the group of sectors previously
defined in the Table 3-4. Once after a group of sectors are protected, any program or erase operation
is not allowed in the protected sector group. The
previously protected sectors must be unprotected
by one of the unprotect methods provided here
before changing data in those sectors. Sector protection can be implemented via two methods.
- Manufacturer ID
- Device ID
- Security sector lock-indicator
- 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 ,
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.
- In-system protection
- A9 High-voltage protection
To check whether the sector group protection was
successfully executed or not, another operation
called “protect verification” needs to be performed after the protection operation on a group of
sectors. 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 (8.5V~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. 29 for timing diagram
and Fig. 3 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 (8.5V~12.5V) on address pin A9 and control pin OE# with A6=0, A1=1 and A0=0. Refer to
Fig. 31 for timing diagram and Fig. 5 for the protection algorithm.
SECTOR UNPROTECTION
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
RESET# tied to the System Reset
The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the

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
ES29DL320 device. All unprotection and unprotect
verification cycles are summarized in detail at the
Table 1.
If the system asserts VIL on the WP#/ACC pin, the
device disables program and erase functions in the
two “outermost” 8Kbytes boot sectors independently of whether those sectors were protected or
unprotected using the method described in “Sector
Group Protection and Unprotection”. The two outermost of 8 Kbyte boot sectors are the two sectors
containing the lowest addresses in a bottom-bootconfigured device, or the two sectors containing the
highest addresses in a top-boot-configured device.
If the system asserts VIH on the WP#/ACC pin, the
device reverts to whether the two outermost 8
Kbyte boot sectors were last set to be protected or
unprotected. That is, sector protection or unprotection for these two sectors depends on whether they
were last protected or unprotected using the
method described in “Sector Group Protection and
Unprotection”.
- In-system unprotection
- A9 High-voltage unprotection
- Temporary sector unprotection
In-System Unprotection
“In-system unprotection”, the primary method,
requires VID (8.5V~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. 29 for timing diagram
and Fig. 4 for the unprotection algorithm.
Note that the WP#/ACC pin must not be left floating
or unconnected; inconsistent behavior of the device
may result.
A9 High-Voltage Unprotection
START
“High-voltage unprotection”, the alternate method
intended only for programming equipment, must
force VID (8.5V~12.5V) on address pin A9 and control pin OE# with A6=1, A1=1 and A0=0. Refer to
Fig. 32 for timing diagram and Fig. 6 for the unprotection algorithm.

Temporary Sector Unprotect
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 (8.5V~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. 27
shows the timing diagrams for this feature.

method of protecting certain boot sectors without
using VID. This function is one of two provided by the
WP#/ACC pin.

SECURITY SECTOR
The security sector of the ES29DL320 device provides an extra flash memory space that enables
permanent part identification through an Electronic
Serial Number (ESN). The security sector uses a
Security Lock-Indicator Bit (DQ7) to indicate
whether or not the security sector is locked when
shipped from the factory. This bit is permanently set
at the factory and cannot be changed, which prevents cloning of a factory locked part. This ensures
the security of the ESN once the product is shipped
to the field. Note that the ES29DL320 has a security sector size of 256 bytes.
ESN ( Electronic Serial Number )
In devices that have an ESN, a Bottom Boot device
will have the 16-byte (8-word) ESN in sector 0 at
addresses 000000h-00000Fh in byte mode (or
000000h-000007h in word mode). In the Top Boot
device the ESN will be in sector 70 at addresses
3FFF00h-3FFF0Fh in byte mode (or 1FFF80h1FFF87h in word mode). Note that in upcoming top
boot versions of this device, the ESN will be located
in sector 70 at addresses 3FFF00h-3FFF0Fh in byte
mode (or 1FFF80h-1FFF87h in word mode).
Security Lock-Indicator Bit (DQ7)
In the device, the security sector can be provided in
either factory locked version or customer lockable
version. The factory-locked version is always protected when shipped from the factory, and has the
security lock-indicator bit permanently set to a “1”.
The customer-lockable version is shipped with
the security sector unprotected, allowing customers
to utilize the sector in any manner they choose. The
customer-lockable version has the security lockindicator bit permanently set to a “0”. Thus, the
security lock-Indicator bit prevents customer-lockble devices from being used to replace devices that
are factory locked.
ESI’s Special-Code Service
Customers may opt to have their code programmed
by ESI through the ESI’s Special-Code service. ESI
programs the customer’s code, with or without the
random ESN. The devices are then shipped from
ESI’s factory with the Security Sector permanently
locked. Contact an ESI representative for details on
using ESI’s Special-Code service.
Customer-Lockable Device
The customer lockable version allows the security
sector to be freely programmed or erased and then
permanently locked. Note that the ES29DL320 has
a security sector size of 256 bytes (128 words). Note
that the accelerated programming (ACC) and unlock
bypass functions are not available when programming the security sector.
Access to the Security Sector
The security sector can be accessed through a
command sequence: Enter security and Exit
security sector commands. After the system has
written the Enter security sector command
sequence, it may read the security sector by using
the addresses normally occupied by the boot sectors. This mode of operation continues until the system issues the exit security sector command
sequence, or until power is removed from the
device. On power-up, or following a hardware reset,
the device returns to read mode in which the normal boot sectors can be accessed, instead of the
security sector.
Protection of the Security Sector
The security sector area can be protected using the
following procedures: Write the three-cycle “Enter
security sector command” sequence, and then following the in-system sector protect algorithm as
shown in Fig. 2, except that RESET# may be at
either VIH or VID. This allows in-system protection
of the security sector without raising any device pin
to a high voltage. Note that this method is only applicable to the security sector. To verify the protect/
unprotect status of the security sector. follow the
algorithm shown in Fig. 2.
Factory-Locked Device
In a factory-locked device, the security sector is
protected when the device is shipped from the factory. The security sector cannot be modified in any
way. The device is available preprogrammed with
one of the following:

can 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.
Start
RESET# =
VIH or VID
If data=00h, security
sector is unprotected.
If data=01h, security
sector is protected
Low Vcc Write inhibit
When Vcc is less than VLKO, the device does not
accept any write cycles. This protects data during
Vcc power-up and power-down. The command register and all internal program/erase circuits are disabled, and the device resets to 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.

Read from security

Noise pulses of less than 5ns (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.
Figure 2. Security Sector Protect Verify
Exit from the Security Sector
Power-up Write Inhibit
Once the Security Sector is locked protected and
verified, the system must write the Exit Security
Sector Region command sequence to return to
reading and writing the remainder of the array.
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.
Caution for the Security Sector Protection
The security sector protection must be used with
caution since, once protected, there is no procedure available for unprotecting the security sector
area and none of the bits in the security sector
memory space can be modified in any way.
HARDWARE DATA PROTECTION
The ES29DL320 device provides some protection
measures against accidental erasure or programming caused by spurious system level signals that
may exist during power transition. During powerup, 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 operation

2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector/Sector
Block Protection and Unprotection” section.
3. If WP#/ACC=VIL, the two outermost boot sectors remain protected. If WP#/ACC=VIH, the two outermost boot sector protection
depends on whether they were last protected or unprotected using the method described in “Sector/Sector Block Protection and
Unprotection”. If WP#/ACC=VHH, all sectors will be unprotected.

ADVANCED INFORMATION
Excel Semiconductor inc.
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 ES29DL320 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. 18 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 banks 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 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.
READING ARRAY DATA
The device is automatically set to reading array data
after device power-up. No commands are required
to retrieve data. Each bank 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 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-suspendread mode. Once programming begins, however, the
device ignores reset commands until the operation is
complete.
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 within
the same bank. 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 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.
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.
If DQ5 goes high during a program or erase operation, writing the reset command returns the bank to
the read mode (or erase-suspend-read mode if that
bank was in Erase-Suspend).

AUTOSELECT COMMAND
SECURITY SECTOR COMMAND
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.
In the ES29DL320 device, the security sector region
(256 bytes) provides a secured data area containing
a random, sixteen-byte electronic serial number(ESN) or customer’s security codes. The security sector region can be accessed by issuing the
three-cycle Enter Security Sector command
sequence. The device continues to access the
security sector region until the system issues the
four-cycle Exit Security Sector command
sequence. The Exit Security Sector command
sequence returns the device to normal operation.
Table 9 shows the address and data requirements
for both command sequences. Note that the accelerated programming function by WP#ACC and
unlock bypass mode are not available when the
device has entered the security sector. Refer to the
Fig. 7 for the security sector operation.

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 a bank 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 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.

BYTE / WORD PROGRAM
Program Status Bits : DQ7, DQ6 or RY/BY#
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, commands related with the security
sector, and CFI modes are unavailable while a programming operation is in progress.
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
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
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 that bank has
returned to the read mode, to ensure data integrity.
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 that bank 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”.

Unlock Bypass
In the ES29DL320 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. That bank
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.

Commands Ignored during Erase Operation
The device offers accelerated program operations
through the WP#/ACC pin. When the system
asserts VHH on the WP#/ACC pin, 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 WP#/ACC pin to accelerate
the operation. Note that the WP#/ACC pin must not
be at VHH in any operation other than accelerated
programming, or device damage may result. In
addition, the WP#/ACC pin must not be left floating
or unconnected; inconsistent behavior of the device
may result. Fig. 8 illustrates the algorithm for the
program operation. Refer to the Erase and Program
Operations table in the AC Characteristics section
for parameters, and Fig. 22 for timing diagrams.
Any command 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. Fig. 9 illustrates
the algorithm for the erase operation. Refer to the
Erase and Program Operations tables in the AC
Characteristics section for parameters, and Fig. 23
section for timing diagrams.
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, security sector, and CFI modes are unavailable while an
erase operation is in progress.
CHIP ERASE COMMAND
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.
Embedded Sector Erase Algorithm
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 these operations.

Sector Erase Time-out Window and DQ3
Status Bits : DQ7,DQ6,DQ2, or RY/BY#
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 50us, 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 reenabled after the last Sector Erase command is
written. 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 Sector Erase 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 DQ7,DQ6,DQ2, or RY/BY# in
the erasing bank. Refer to the Write Operation Status
section Table 10 for information on these status bits.
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 sequence
should be reinitiated once that bank has returned to
reading array data, to ensure data integrity.
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.
Fig. 9 illustrates the algorithm for the erase operation. Refer to the Erase and Program Operations
tables in the AC Characteristics section for parameters, and Fig. 23 section for timing diagrams.
ERASE SUSPEND/ERASE RESUME
An erase operation is a long-time operation so that
two useful commands are provided in the
ES29DL320 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.

Read and Program during Erase-SuspendRead Mode
After the erase operation has been suspended, the
bank enters the erase-suspend-read mode. The
system can read data from or program data to any
sector not selected for erasure. (The device “erase
suspends” all sectors selected for erasure.) Reading
at any address within erase-suspended sectors produces status information on DQ7-DQ0. The system
can use DQ7, or DQ6 and DQ2 together, to determine if a sector is actively erasing or is erase-suspended. Refer to the Write Operation Status section
for information on these status bits (Table 10).
After an erase-suspended program operation is
complete, the bank returns to the erase-suspendread mode. The system can determine the status for
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.
Autoselect during Erase-Suspend- Read

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).
Erase Resume Command
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.

WRITE OPERATION STATUS
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.
In the ES29DL320 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 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.
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.
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 that bank returns to the read mode.
Table 10 shows the outputs for Data# Polling on
DQ7. Fig. 11 shows the Data# Polling algorithm. Fig.
24 in the AC Characteristics section shows the
Data# Polling timing diagram.

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

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.

which sectors are erasing or erase-suspended.
Alternatively, the system can use DQ7(see the subsection on DQ7:Data# Polling). DQ6 also toggles

Figure 11. 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 one of the banks in the erasesuspend-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.
12 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. 25 shows the toggle bit timing diagram.

Refer to Fig. 12 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. 12).

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 ( 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.
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.)

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.

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.
