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.
