Functional Description

The CY7C436X6 is a monolithic, high-speed, low-power, CMOS Bidirectional Synchronous (clocked) FIFO memory, which supports clock frequencies up to 133 MHz and has read access times as fast as 6 ns. Two independent 1K/4K/16K x36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions.

Features

? High-speed, low-power, first-in first-out (FIFO) memories w/ three

independent ports (one bidirectional x36,

and two unidirectional x18)

? 1K x36/x18x2 (CY7C43646)

? 4K x36/x18x2 (CY7C43666)

? 16K x36/x18x2 (CY7C43686)

? 0.35-micron CMOS for optimum speed/power

? High speed 133-MHz operation (7.5-ns read/write

cycle times)

? Low power

— ICC= 100 mA

— ISB= 10 mA

? Fully asynchronous and simultaneous read and write

operation permitted

? Mailbox bypass register for each FIFO

? Parallel and Serial Programmable Almost Full and

Almost Empty flags

? Retransmit function

? Standard or FWFT mode user-selectable

? Partial Reset

? Big or Little Endian format for word or byte bus sizes

? 128-pin TQFP packaging

? Easily expandable in width and depth
