CY7C4221 - 1 K / 2 K x 9 Synchronous FIFOs

General Description

The CY7C42X1 are high-speed, low-power FIFO memories with clocked read and write interfaces.

Key Features

  • High-speed, low-power, first-in first-out (FIFO) memories.
  • 1 K × 9 (CY7C4221).
  • 2 K × 9 (CY7C4231).
  • High-speed 66.7 MHz operation (15 ns read/write cycle time).
  • Low power (ICC = 35 mA).
  • Fully asynchronous and simultaneous read and write operation.
  • Empty, Full, and Programmable Almost Empty and Almost Full status flags.
  • TTL-compatible.
  • Output Enable (OE) pin to three-state the output bus.
  • Independent read and write enable pins.
  • Center power a.
