Renesas Electronics SRAM, 71256SA15TPG- 1MB

The Renesas Electronics CMOS static RAM 6 is a high-speed static RAM organized as 64K x 16. It is fabricated using high-performance, high-reliability CMOS technology. This state-of-the-art technology, combined with innovative circuit design techniques, provides a cost-effective solution for high-speed memory needs. All bidirectional inputs and outputs of the RAM are TTL-compatible and operation is from a single 5V supply. Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation.

One chip select plus one output enable pin
Bidirectional data inputs and outputs directly TTL compatible
Low power consumption via chip deselect
Upper and lower byte enable pins
