General Description

The A62S8308 is a low operating current 2,097,152-bit

static random access memory organized as 262,144

words by 8 bits and operates on a low power supply

voltage from 2.7V to 3.6V.

Inputs and three-state outputs are TTL compatible and

allow for direct interfacing with common system bus

structures.

Two chip enable inputs are provided for power down and

a device enable and an output enable input are included

for easy interfacing.

Data retention is guaranteed at a power supply voltage

as low as 2V.
