UT62L1024

128KX8 BIT LOW POWER CMOS SRAM

GENERAL DESCRIPTION

The UT62L1024 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.

Easy memory expansion is provided by using two

chip enable inputs.( CE ,CE2) It is particularly well

suited for battery back-up nonvolatile memory

application.

The UT62L1024 operates from a single 2.7V~ 3.6V

power supply and all inputs and outputs are fully

TTL compatible.
