CY7C456 - (CY7C455 - CY7C457) Cascadable Colcked FIFOs

Download the CY7C456 datasheet PDF. This datasheet also covers the CY7C455 variant, as both devices belong to the same (cy7c455 - cy7c457) cascadable colcked fifos family and are provided as variant models within a single manufacturer datasheet.

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.
  • 512 x 18 (CY7C455).
  • 1,024 x 18 (CY7C456).
  • 2,048 x 18 (CY7C457).
  • 0.65 micron CMOS for optimum speed/power.
  • High-speed 83-MHz operation (12 ns read/write cycle time).
  • Low power.
  • ICC=90 mA.
  • Fully asynchronous and simultaneous read and write operation.
  • Empty, Full, Half Full, and programmable Almost Empty and Almost Full status flags.
  • TTL comp.
