Ordering number : EN4163A
Asynchronous Silicon Gate CMOS LSI
LC36256AL, AML-70/85/10/12
256 K (32768 words × 8 bits) SRAM
Overview
The LC36256AL, AML are fully asynchronous silicon
gate CMOS static RAMs with an 32768 words × 8 bits
configuration.
This series have CE chip enable pin for device
select/nonselect control and an OE output enable pin for
output control, and features high speed as well as low
power dissipation.
For these reasons, the series is especially suited for use in
systems requiring high speed, low power, and battery
backup, and it is easy to expand memory capacity.
