Functional Description
The CY7C451, CY7C453, and CY7C454 are high-speed, low-power, first-in first-out (FIFO) memories with clocked read and write interfaces. Both FIFOs are 9 bits wide. The CY7C451 has a 512-word by 9-bit memory array, the CY7C453 has a 2048-word by 9-bit memory array, and the CY7C454 has a 4096-word by 9-bit memory array. Devices can be cascaded to increase FIFO depth. Programmable features include Almost Full/Empty flags and generation/checking of parity. These FIFOs provide solutions for a wide variety of data buffering needs, including high-speed data acquisition, multiprocessor interfaces, and communications buffering.
