70T3719M中文资料256K x 72 Sync, 3.3V/2.5V Dual-Port数据手册Renesas规格书

描述 Description

The 70T3719M is a high-speed 256K x 72 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. The 70T3719M can support an operating voltage of either 3.3V or 2.5V on one or both ports, controllable by the OPT pins. The power supply for the core of the device (VDD) is at 2.5V.
