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
• 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 )
- 70ns for regulated Vcc range ( 3.0V - 3.6V )
• Program and erase time
- Program time : 6us/byte, 8us/word ( typical )
- Sector erase time : 0.7sec/sector ( typical )
• Power consumption (typical values)
- 200nA in standby or automatic sleep mode
- 9mA active read current at 5 MHz
- 15mA active write current during program or erase

GENERAL PRODUCT DESCRIPTION
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 config-
urable 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 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 ES29LV160 offers access time as fast as 70ns
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.
The ES29LV160 is completely compatible with the
JEDEC standard command set of single power sup-
ply 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.
