70V3379 - Block Diagram
Description
The 70V3379 is a high-speed 32K x 18-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 70V3379 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 3.3V.
