Product Summary
The CY7C43683-15AC is a monolithic, high-speed, low-power, CMOS Unidirectional 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 x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. The CY7C43683-15AC is a synchronous (clocked) FIFO, meaning each port employs a synchronous interface. All data transfers through a port are gated to the LOW-to-HIGH transition of a port clock by enable signals. The CY7C43683-15AC has two modes of operation: In the CY Standard Mode, the first word written to an empty FIFO is deposited into the memory array.
