M68AW031A

SUMMARY DESCRIPTION

The M68AW031A is a 256 Kbit (262,144 bit)

CMOS SRAM, organized as 32,768 bytes 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 2.7 to 3.6V supply. This device has an au-

tomatic power-down feature, reducing the power

consumption by over 99% when deselected.

The M68AW031A is available in SO28 (28-lead

Small Outline) and TSOP28 (28-lead Thin Small

Outline, Standard and Reverse Pinout) packages.
