709279L12PFGI - Renesas Electronics

Description: The 709279 is a high-speed 32K x 16 bit synchronous Dual-Port RAM that has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode.
