Description

The M68AW256D 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 M68AW256D is available in TFBGA48 (0.75 mm pitch) and in TSOP44 Type II packages.
