General Description

The LP62S2048A-I is a low operating current 2,097,152-bit static random access memory organized as 262,144 words by 8 bits and operates on a low power supply range: 2.7V to 3.3V. It is built using AMICs high performance CMOS process.

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.
