CY7C419 - 256/512/1K/2K/4K x 9 Asynchronous FIFO

General Description

The CY7C419, CY7C420/1, CY7C424/5, CY7C428/9, and CY7C432/3 are first-in first-out (FIFO) memories offered in 600-mil wide and 300-mil wide packages.

Key Features

  • Asynchronous first-in first-out (FIFO) buffer memories.
  • 256 x 9 (CY7C419).
  • 512 x 9 (CY7C421).
  • 1K x 9 (CY7C425).
  • 2K x 9 (CY7C429).
  • 4K x 9 (CY7C433).
  • Dual-ported RAM cell.
  • High speed 50 MHz read and write independent of depth and width.
  • Low operating power: ICC = 35 mA.
  • Empty and full flags (Half Full flag in standalone).
  • TTL compatible.
  • Retransmit in standalone.
  • Expandable in width.
  • PLCC, 7x7 TQFP, SOJ, 300-mil, and 600-mil DI.
