FEATURES
Functional Description
The CY7C436X6 is a monolithic, high-speed, low-power, CMOS Bidirectional Synchronous (clocked) FIFO memory, which supports clock frequencies up to 133 MHz and has read access times as fast as 6 ns. Two independent 1K/4K/16K x36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions.
Features
• High-speed, low-power, first-in first-out (FIFO) memories w/ three
independent ports (one bidirectional x36,
and two unidirectional x18)
• 1K x36/x18x2 (CY7C43646)
• 4K x36/x18x2 (CY7C43666)
• 16K x36/x18x2 (CY7C43686)
• 0.35-micron CMOS for optimum speed/power
• High speed 133-MHz operation (7.5-ns read/write
cycle times)
• Low power
— ICC= 100 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 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
