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 address access and cycle times. It requires a single 5V ±10% supply, and all inputs and outputs are TTL compatible.
