DESCRIPTION

The M68Z128W is a 1 Mbit (1,048,576 bit) Fast

CMOS SRAM, organized as 131,072 words by 8

bits. The device features fully static operation re-

quiring no external clocks or timing strobes, with

equal address access and cycle times. It requires

a single 3.0V (+0.6V / –0.3V) supply, and all inputs

and outputs are TTL compatible. This device has

an automatic power-down feature, reducing the

power consumption by over 99% when deselect-

ed. The M68Z128W is available in the standard

450mil-wide TSOP type 1 package.
