GENERAL DESCRIPTION
The UT62L1024(E) 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.
The UT62L1024(E) is designed for low power
application. It is particularly well suited for battery
back-up nonvolatile memory application.
The UT62L1024(E) operates from a single 2.7V ~
3.6V power supply and all inputs and outputs are
fully TTL compatible.
