M68AW256M
SUMMARY DESCRIPTION
The M68AW256M is a 4 Mbit (4,194,304 bit)
CMOS SRAM, organized as 262,144 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 M68AW256 is available in TFBGA48 (0.75 mm
pitch) and in TSOP44 Type II packages.
