CY7C43684

1K/4K x36 x2 Bidirectional Synchronous

FIFO with Bus Matching

• Fully asynchronous and simultaneous read and write

operation permitted

Features

• High-speed,low-power,bidirectional,First-In,First-Out

(FIFO) memories with bus matching capabilities

• 1K x36 x2 (CY7C43644)

• Mailbox bypass register for each FIFO

• Parallel and Serial Programmable Almost-Full and

Almost-Empty flags

• 4K x36 x2 (CY7C43664)

• Retransmit function

• 16K x36 x2 (CY7C43684)

• 0.35-micron CMOS for optimum speed/power

• Standard or FWFT mode user selectable

• Partial Reset

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

cycle times)

• Low power

— I_CC= 100 mA

— I_SB= 10 mA

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

• 128-pin TQFP packaging

• Easily expandable in width and depth
