CY7C43666

CY7C43686

1K/4K/16K x36/x18/x2 Tri Bus FIFO

• Fully asynchronous and simultaneous read and write

operation permitted

• Mailbox bypass register for each FIFO

Features

• High-speed, low-power, first-in first-out (FIFO) memo-

ries w/ three independent ports (one bidirectional x36,

and two unidirectional x18)

• 1K x36/x18x2 (CY7C43646)

• 4K x36/x18x2 (CY7C43666)

• 16K x36/x18x2 (CY7C43686)

• 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

• 0.35-micron CMOS for optimum speed/power

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

cycle times)

• Low power

— I_CC= 100 mA

— I_SB= 10 mA
