LP62S2048AXR-T

256K X 8 BIT LOW VOLTAGE CMOS SRAM

AMIC Technology 

LP62S2048A-T Series

256K X 8 BIT LOW VOLTAGE CMOS SRAM

Features

General Description

Power supply range: 2.7V to 3.6V

Access times: 55/70 ns (max.)

Current:

Very low power version: Operating: 55ns: 25mA (max.)

70ns: 20mA (max.)

Standby: 10µA (max.)

Full static operation, no clock or refreshing required

All inputs and outputs are directly TTL-compatible

Common I/O using three-state output

Output enable and two chip enable inputs for easy

application

Data retention voltage: 2V (min.)

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

forward & reverse type) and 36-pin CSP packages

The LP62S2048A-T 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 3.6V.

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.

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.
