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 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 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.
