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.
