HARDWARE FEATURES
• Hardware reset input pin ( RESET#)
- Provides a hardware reset to device
- Any internal device operation is terminated and the
device returns to read mode by the reset
• Ready/Busy# output pin ( RY/BY#)
- Provides a program or erase operational status
about whether it is finished for read or still being
progressed
• WP#/ACC input pin
- Two outermost boot sectors are protected when
WP# is set to low, regardless of sector protection
- Program speed is accelerated by raising WP#/ACC
to a high voltage (8.5 ~9.5V)
• Sector protection / unprotection ( RESET# , A9 )
- Hardware method of locking a sector to prevent
any program or erase operation within that sector
- Two methods are provided :
- In-system method by RESET# pin
- A9 high-voltage method for PROM programmers
• Temporary Sector Unprotection ( RESET# )
- Allows temporary unprotection of previously
protected sectors to change data in-system
• Low Vcc write inhibit
• Manufactured on 0.18um process technology
• Compatible with JEDEC standards
- Pinout and software compatible with single-power
supply flash standard
DEVICE PERFORMANCE
• Read access time
- 55ns/70ns/90n for normal Vcc range ( 2.7V - 3.6V )
• Program and erase time
- Program time : 6us/byte, 8us/word ( typical )
- Accelerated program time : 4us/word ( typical )
- Sector erase time : 0.7sec/sector ( typical )

GENERAL PRODUCT DESCRIPTION
The ES29DL320D 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 pro-
vided : 8Kbytes x 8 and 64Kbytes x 63. The device
is manufactured with ESI’s proprietary, high perfor-
mance 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 stan-
dard EPROM programmers. The device offers min-
imum endurance of 100,000 program/erase cycles
and more than 10 years of data retention.
The ES29DL320D offers access time as fast as
55ns, 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 embed-
ded 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 num-
ber 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.
Therefore, this lock indicator bit (DQ7) can be prop-
erly 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 cus-
tomers when it is used as a customer-lockable ver-
sion. 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-lock are
available to customers ( ESI’s
Special-Code ser-
vice
) The ES29DL320D 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 tim-
ings 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.
Simultaneous Read / Write Operation
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
non-busy 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 pro-
gram or erase operations
The ES29DL320D can be organized as either a top
or bottom boot sector configuration.
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-lock-
able).
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.
