The AS6C4008 is a 4,194,304-bit low power

CMOS static random access memory organized as

524,288 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 AS6C4008 is well designed for very low power

system applications, and particularly well suited for

battery back-up non-volatile memory application.

The AS6C4008 operates from a single power

supply of 2.7V~ 5.5Vand all inputs and outputs are

fully TTL compatible
