IDT71V016SA 3.3V CMOS Static RAM 1 Meg (64K x 16-Bit) Features Description ◆ The IDT71V016 is a 1,048,576-bit high-speed Static RAM organized as 64K x 16. It is fabricated using IDT’s high-perfomance, high-reliability CMOS technology. This state-of-the-art technology, combined with innovative circuit design techniques, provides a cost-effective solution for highspeed memory needs. The IDT71V016 has an output enable pin which operates as fast as 5ns, with address access times as fast as 10ns. All bidirectional inputs and outputs of the IDT71V016 are LVTTL-compatible and operation is from a single 3.3V supply. Fully static asynchronous circuitry is used, requiring no clocks or refresh for operation. The IDT71V016 is packaged in a JEDEC standard 44-pin Plastic SOJ, a 44-pin TSOP Type II, and a 48-ball plastic 7 x 7 mm FBGA. ◆ ◆ ◆ ◆ ◆ ◆ ◆ 64K x 16 advanced high-speed CMOS Static RAM Equal access and cycle times — Commercial: 10/12/15/20ns — Industrial: 12/15/20ns One Chip Select plus one Output Enable pin Bidirectional data inputs and outputs directly LVTTL-compatible Low power consumption via chip deselect Upper and Lower Byte Enable Pins Single 3.3V power supply Available in 44-pin Plastic SOJ, 44-pin TSOP, and 48-Ball Plastic FBGA packages Functional Block Diagram OE A0 – A15 Output Enable Buffer Address Buffers Row / Column Decoders I/O15 CS 8 Chip Enable Buffer High Byte I/O Buffer 8 I/O8 WE Write Enable Buffer 16 64K x 16 Memory Array Sense Amps and Write Drivers I/O7 8 Low Byte I/O Buffer 8 I/O0 BHE Byte Enable Buffers BLE 3834 drw 01 JUNE 2002 1 ©2000 Integrated Device Technology, Inc.

A write occurs during the overlap of a LOW CS, LOW BHE or BLE, and a LOW WE. 2. OE is continuously HIGH. If during a WE controlled write cycle OE is LOW, tWP must be greater than or equal to tWHZ + tDW to allow the I/O drivers to turn off and data to be placed on the bus for the required tDW. If OE is HIGH during a WE controlled write cycle, this requirement does not apply and the minimum write pulse is as short as the specified tWP. 3. During this period, I/O pins are in the output state, and input signals must not be applied. 4. If the CS LOW or BHE and BLE LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in a high-impedance state. 5.
