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
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 inno-
vative circuit design techniques, provides a cost-effective solution for high-
speed 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.
