UT62L25716(I)

256K X 16 BIT LOW POWER CMOS SRAM

GENERAL DESCRIPTION

The UT62L25716(I) is a 4,194,304-bit low power

CMOS static random access memory organized as

262,144 words by 16 bits.

The UT62L25716(I) operates from a single 2.7V ~

3.6V power supply and all inputs and outputs are

fully TTL compatible.

The UT62L25716(I) is designed for low power

system applications. It is particularly well suited for

use in high-density low power system applications.
