71V416S 3.3V CMOS Static RAM 71V416L 4 Meg (256K x 16-Bit) Features Description 256K x 16 advanced high-speed CMOS Static RAM The IDT71V416 is a 4,194,304-bit high-speed Static RAM organized JEDEC Center Power / GND pinout for reduced noise. as 256K x 16. It is fabricated using high-performance, high-reliability Equal access and cycle times CMOS technology. This state-of-the-art technology, combined with inno- Commercial and Industrial: 10/12/15ns vative circuit design techniques, provides a cost-effective solution for high- One Chip Select plus one Output Enable pin speed memory needs. Bidirectional data inputs and outputs directly The IDT71V416 has an output enable pin which operates as fast as LVTTL-compatible 5ns, with address access times as fast as 10ns. All bidirectional inputs and Low power consumption via chip deselect outputs of the IDT71V416 are LVTTL-compatible and operation is from a Upper and Lower Byte Enable Pins single 3.3V supply. Fully static asynchronous circuitry is used, requiring Single 3.3V power supply no clocks or refresh for operation. Available in 44-pin, 400 mil plastic SOJ package and a 44- The IDT71V416 is packaged in a 44-pin, 400 mil Plastic SOJ and a pin, 400 mil TSOP Type II package and a 48 ball grid array, 44-pin, 400 mil TSOP Type II package and a 48 ball grid array, 9mm x 9mm x 9mm package. 9mm package.
