GENERAL DESCRIPTION
The ASI AS5LC1008 is a very high-speed, low power,
131,072-word by 8-bit CMOS static RAM in revolutionary
pinout. The AS5LC1008 is fabricated using high-performance
CMOS technology. This highly reliable process coupled with
innovative circuit design techniques, yields higher performance
and low power consumption devices.
When CE\ is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be reduced
down to 250µW (typical) with CMOS input levels.
The AS5LC1008 operates from a single 3.3V power supply
and all inputs are TTL-compatible.
