The IDT71V321 is designed to be used as a stand-alone 8-bit Dual-Port RAM. The device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature, controlled by CE, permits the on chip circuitry of each port to enter a very low standby power mode. Fabricated using IDT's CMOS high-performance technology, these devices typically operate on only 250mW of power. Low-power (L) versions offer battery backup data retention capability, with each Dual-Port typically consuming 200µW from a 2V battery. The IDT71V321 devices are packaged in a 52-pin PLCC and a 64-pin TQFP (thin plastic quad flatpack). FUNCTIONAL BLOCK DIAGRAM OEL R/ OE.
