General Description
The A62S7308B is a low operating current 1048,576-bit
static random access memory organized as 131,072
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.
