General Description
The LP62S16256E-I is a low operating current 4,194,304-bit
static random access memory organized as 262,144 words
by 16 bits and operates on low power voltage from 2.7V to
3.3V. It is built using AMIC's high performance CMOS
process.
Inputs and three-state outputs are TTL compatible and allow
for direct interfacing with common system bus structures.
The chip enable input is provided for POWER-DOWN,
device enable. Two byte enable inputs and an output enable
input are included for easy interfacing.
Data retention is guaranteed at a power supply voltage as
low as 2.0V.
