Description

GENERAL DESCRIPTION

The UT62256C is a 262,144-bit low power CMOS static random access memory organized as 32,768 words by 8 bits. It is fabricated using high performance, high reliability CMOS technology.
The UT62256C is designed for high-speed and low power application. It is particularly well suited for battery back-up nonvolatile memory application.
The UT62256C operates from a single 5V power supply and all inputs and outputs are fully TTL compatible.
