General Description

The LP621024D-T is a low operating current 1,048,576-

bit static random access memory organized as 131,072

words by 8 bits and operates on a single 5V power

supply.

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 device enable and an output enable input is included

for easy interfacing.

Data retention is guaranteed at a power supply voltage

as low as 2V.
