General Description
The LP62S16128B-T is a low operating current
2,097,152-bit static random access memory organized as
131,072 words by 16 bits and operates on low power
voltage from 2.7V to 3.6V. 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.
Pin Configurations
n TSOP
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 2V.
