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
