The UT62W1024 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 UT62W1024 is designed for low power
application. It is particularly well suited for
battery back-up nonvolatile memory application.
The UT62W1024 operates from a wide range of
2.7V~ 5.5V power supply and all inputs and
outputs are fully TTL compatible.
