General Description

The LP62S1024B-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 low power voltage: 2.7V to 3.6V. 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 1.5V.
