4 / 21 page ![]() M68AW511A 4/21 SUMMARY DESCRIPTION The M68AW511A is a 4 Mbit (4,194,304 bit) CMOS SRAM, organized as 524,288 words by 8 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 automatic power-down feature, reducing the power consumption by over 99% when deselected. The M68AW511A is available in two different packages: 32-lead TSOP Type II and 32-lead SO.
