SUMMARY DESCRIPTION

The M68AW512M is a 8 Mbit (8,388,608 bit)

CMOS SRAM, organized as 524,288 words by 16

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 M68AW512M is available in TSOP44 Type II

packages.
