GENERAL DESCRIPTION

The AS6C1608 is a 16,777,216-bit low power

CMOS static random access memory organized as

2,097,152 words by 8 bits. It is fabricated using very

high performance, high reliability CMOS technology.

Its standby current is stable within the range of

operating temperature.

The AS6C1608 is well designed for very low power

system applications, and particularly well suited for

battery back-up nonvolatile memory application.

The AS6C1608 operates from a single power

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

fully TTL compatible
