GENERAL DESCRIPTION
The UT62256C(E) 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(E) is designed for high-speed and
low power application.
It is particularly well suited
for battery back-up nonvolatile memory application.
The UT62256C(E) operates from a single 5V power
supply and all inputs and outputs are fully TTL
compatible
