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 requiring 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 automatic 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.
