The IDT70V659/58/57 is designed to be used reads or writes to any location in memory. An automatic power down as a stand-alone 4/2/1Mbit Dual-Port RAM or as a combination MASTER/ SLAVE Dual-Port RAM for 72-bit-or-more word system. Using the feature controlled by the chip enables (either CE0 or CE1) permit the MASTER/SLAVE Dual-Port RAM approach in 72-bit or wider memory on-chip circuitry of each port to enter a very low standby power mode. The 70V659/58/57 can support an operating voltage of either 3.3V system applications results in full-speed, error-free operation without the or 2.5V on one or both ports, controlled by the OPT pins. The power supply need for additional discrete logic. for the core of the device (VDD) remains at 3.3V.
