Functional Block Diagram
The IDT71V416 is a 4,194,304-bit high-speed Static RAM organized
as 256K x 16. It is fabricated using high-performance, 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 IDT71V416 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 IDT71V416 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 IDT71V416 is packaged in a 44-pin, 400 mil Plastic SOJ and a
44-pin, 400 mil TSOP Type II package and a 48 ball grid array, 9mm x
A0 - A17
