CY7C43684AV

3.3V 1K/4K/16K x36 x2 Bidirectional Synchronous FIFO with

Bus Matching

• Fully asynchronous and simultaneous Read and Write

Features

operation permitted

• 3.3V high-speed, low-power, bidirectional, First-In

First-Out (FIFO) memories w/ bus matching capabilities

• 1K × 36 × 2 (CY7C43644AV)

• Mailbox bypass register for each FIFO

• Parallel and Serial Programmable Almost Full and

Almost Empty flags

• 4K × 36 × 2 (CY7C43664AV)

• Retransmit function

• 16K × 36 × 2 (CY7C43684AV)

• 0.25-micron CMOS for optimum speed/power

• Standard or FWFT user selectable mode

• Partial Reset

• High-speed 133-MHz operation (7.5-ns Read/Write

cycle times)

• Low power

— I_CC= 60 mA

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

• 128-pin TQFP packaging

• Easily expandable in width and depth

— I_SB= 10 mA
