GENERAL DESCRIPTION
The UT62L12916 is a 2,097,152-bit low power CMOS
static random access memory organized as 131,072
words by 16 bits.

The UT62L12916 operates from a single 2.5V ~ 3.6V
power supply and all inputs and outputs are fully TTL
compatible.

The UT62L12916 is designed for low power system
applications. It is particularly well suited for use in
high-density low power system applications.
