GENERAL DESCRIPTION

The UT62L12816 is a 2,097,152-bit low power
CMOS static random access memory organized
as 131,072 words by 16 bits.

The UT62L12816 operates from a single 2.7V ~

3.6V power supply and all inputs and outputs are
fully TTL compatible.

The UT62L12816 is designed for low power
system applications. It is particularly suited for
use in high-density high-speed system
applications.
