CY7C43646AV 3.3V 1K 4K 16K x 36 x 18 x 2 Tri Bus FIFO

The CY7C436X6AV is a monolithic, high-speed, low-power, CMOS Bidirectional Synchronous FIFO memory that supports clock frequencies up to 133 MHz and has Read access times as fast as 6 ns. Two independent 1K/4K/16K × 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. The CY7C436X6AV is a synchronous (clocked) FIFO, meaning each por.

Features


• 3.3V high-speed, low-power, First-In First-Out (FIFO) memories with three independent ports (one bidirectional ×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 — ICC= 60 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 FWF.
