Rev. 1.5

128K X 8 BIT LOW POWER CMOS SRAM

GENERAL DESCRIPTION

FEATURES

The UT621024 is a 1,048,576-bit low power

CMOS static random access memory

organized as 131,072 words by 8 bits. It is

fabricated using high performance, high

reliability CMOS technology.

Access time : 35/55/70ns (max.)

Low power consumption :

Operating : 60/50/40 mA (typical)

Standby : 2µA (typical) L-version

1µA (typical) LL-version

The UT621024 is designed for low power

application. It is particularly well suited for

battery back-up nonvolatile memory

application.

Single 5V power supply

All inputs and outputs TTL compatible

Fully static operation

Three state outputs

Data retention voltage : 2V (min.)

The UT621024 operates from a single 5V

power supply and all inputs and outputs are

fully TTL compatible.

Package : 32-pin 600 mil PDIP

32-pin 450 mil SOP

32-pin 8mmx20mm TSOP-1

32-pin 8mmx13.4mm STSOP
