Functional Description

The CY7C436X6AV is a monolithic, high-speed, low-power, CMOS Bidirectional Synchronous FIFO memory that supports clock frequencies up to 133 MHz and has Read access times as fast as 6 ns. Two independent 1K/4K/16K × 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions.

Features

? 3.3V high-speed, low-power, First-In First-Out (FIFO) memories with three independent ports (one bidirectional ×36, and two unidirectional ×18)

? 1K ×36/×18×2 (CY7C43646AV)

? 4K ×36/×18×2 (CY7C43666AV)

? 16K ×36/×18×2 (CY7C43686AV)

? 0.25-micron CMOS for optimum speed/power

? High-speed 133-MHz operation (7.5-ns Read/Write cycle times)

? Low power

— ICC= 60 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 user-selectable mode

? Partial and master reset

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

? 128-pin TQFP packaging

? Easily expandable in width and depth
