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 (12V)
• 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
DEVICE PERFORMANCE
• Read access time
- 90ns/120n for normal Vcc range ( 2.7V - 3.6V )
- 80ns for regulated Vcc range ( 3.0V - 3.6V )
• Program and erase time
- Program time : 9us/byte, 11us/word ( typical )
- Accelerated program time : 8us/word ( typical )
- Sector erase time : 0.7sec/sector ( typical )
• Power consumption (typical values)
- 200nA in standby or automatic sleep mode
- 10 mA active read current at 5 MHz
- 15mA active write current during program or erase

GENERAL PRODUCT DESCRIPTION
The ES29LV320 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 config-
urable by BYTE#. Eight boot sectors and sixty three
main sectors with uniform size are provided :
8Kbytes x 8 and 64Kbytes x 63. The device is man-
ufactured with ESI’s proprietary, high performance
and highly reliable 0.18um CMOS flash technology.
The device can be programmed or erased in-sys-
tem with standard 3.0 Volt Vcc supply ( 2.7V-3.6V)
and can also be programmed in standard EPROM
programmers. The device offers minimum endur-
ance of 100,000 program/erase cycles and more
than 10 years of data retention.
The ES29LV320 offers access time as fast as 80ns
or 90ns, allowing operation of high-speed micropro-
cessors 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.
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. 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-lock are
available to customers ( ESI’s
Special-Code ser-
vice
) The ES29LV320 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.
