n Full static operation, no clock or refreshing required

n All inputs and outputs are directly TTL-compatible

n Common I/O using three-state output

n Output enable and two chip enable inputs for easy

application

n Data retention voltage: 2V (min.)

n Available in 32-pin SOP, TSOP, TSSOP (8X13.4mm)

and 36-pin CSP packages

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 AMIC's 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.
