Functional Description

The CY7C436X2 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 x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions.
