M68AW512D

SUMMARY DESCRIPTION

The M68AW512D is an 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 a Chip

Select pin (E2) for easy memory expansion; when

it is active (E2 high) the device has an automatic

power-down feature, reducing the power con-

sumption by over 99%.

The M68AW512D is available in TFBGA48 (0.75

mm ball pitch) package.
