The UT62L5128 is a 4,194,304-bit high speed
CMOS static random access memory organized as
524,288 words by 8 bits. It is fabricated using high
performance, high reliability CMOS technology.
The UT62L5128 is designed for high speed system
applications. It is particularly well suited for
battery back-up nonvolatile memory applications.
The UT62L5128 operates from a single
2.7V~3.6V power supply and all inputs and
outputs are fully TTL compatible.
