CY7C455 - (CY7C455 - CY7C457) Cascadable Colcked FIFOs

Description

The CY7C455, CY7C456, and CY7C457 are high-speed, low-power, first-in first-out (FIFO) memories with clocked read and write interfaces.

All are 18 bits wide.

The CY7C455 has a 512-word memory array, the CY7C456 has a 1,024-word memory array, and the CY7C457 has a 2,048-word memory array.

Features

  • High-speed, low-power, first-in first-out (FIFO) memories.
