DESCRIPTION

The M68Z512 is a 4 Mbit (4,194,304 bit) CMOS

SRAM, organized as 524,288 words by 8 bits. The

device features fully static operation requiring no

external clocks or timing strobes, with equal ad-

dress access and cycle times. It requires a single

5V ±10% supply, and all inputs and outputs are

TTL compatible.

This device has an automatic power-down feature,

reducing the power consumption by over 99%

when deselected.
