Product Summary

The CY7C4255V-15ASXC is a high-speed, low-power, first-in first-out (FIFO) memory with clocked read and write interfaces. All are 18 bits wide and are pin/functionally compatible to the CY7C42X5V Synchronous FIFO family. The CY7C4255V-15ASXC can be cascaded to increase FIFO depth. Programmable features include Almost Full/Almost Empty flags. Retransmit and Synchronous Almost Full/Almost Empty flag features are available on these devices.
