General Description
The A62S6308 is a low operating current 524,288-bit
static random access memory organized as 65,536
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.
