GENERAL DESCRIPTION

The AS6C1616 is a 16,777,216-bit low power

CMOS static random access memory organized as

1,048,576 words by 16 bits. It is fabricated using

very high performance, high reliability CMOS

technology. Its standby current is stable within the

range of operating temperature.

The AS6C1616 is well designed for low power

application, and particularly well suited for battery

back-up nonvolatile memory application.

The AS6C1616 operates from a single power

supply of 2.7V ~ 3.6V and all inputs and outputs are

fully TTL compatible
