IDT71V321L

The IDT71V321L are high-speed 2K x 8 Dual-Port tatic RAMs with internal interrupt logic for interprocessor communications. he IDT71V321 is designed to be used as a stand-alone 8-bit ual-Port RAM or as a "MASTER" Dual-Port RAM together with the DT71V421 "SLAVE" Dual-Port in 16-or-more-bit memory system applications esults in full speed, error-free operation without the need for additional discrete logic.

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 byCE, 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 325mW of power. Low-power (L) versions offer battery backup data retention capability, with each Dual- Port typically consuming 200W from a 2V battery.

The IDT71V321L devices are packaged in a 52-pin PLCC, a 64-pin TQFP (thin quad flatpack), and a 64-pin STQFP (super thin quad flatpack).
