M5M54R16AJ,ATP-10,-12,-15 is a family of 262144-word by 16-bit static RAMs, fabricated with the high performance CMOS process and designed for high speed application. These devices operate on a single 3.3V supply, and are directly TTL compatible. They include a power down feature as well.
This document describes the M5M54R16A family of 4Mbit (262144-word by 16-bit) CMOS static RAMs. These devices are fabricated with a high-performance CMOS process and operate on a single +3.3V supply, making them directly TTL compatible. Key features include fully static operation without clocks or refresh, a power-down feature controlled by the S pin, and the ability to control lower and upper bytes separately using LB and UB inputs.
