The LP621024D-I 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.
