CY7C43686AV

3.3V 1K/4K/16K x36/x18x2 Tri Bus FIFO

• Fully asynchronous and simultaneous Read and Write

operation permitted

Features

• 3.3V high-speed, low-power, First-In First-Out (FIFO)

memories with three independent ports (one bidirec-

tional ×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

— I_CC= 60 mA

— I_SB= 10 mA

• 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
