GENERAL DESCRIPTION

The UT62V25616(I) is a 4,194,304-bit low power

CMOS static random access memory organized as

262,144 words by 16 bits.

The UT62V25616(I) operates from a single 2.3V ~

2.7V power supply and all inputs and outputs are fully

TTL compatible.

The UT62V25616(I) is designed for low power

system applications. It is particularly suited for use

in high-density high-speed system applications.
