Clock frequencies up to 100 MHz are achievable. Retransmit and Synchronous Almost Full/Almost Empty flag features are a.

The CY7C42X5 are high speed, low power, first-in first-out (FIFO) memories with clocked read and write interfaces. All are 18 bits wide and are pin/functionally compatible to IDT722X5. The CY7C42X5 can be cascaded to increase FIFO depth. Programmable.
