CY7C4245 - 64/256/512/1K/2K/4K x 18 Synchronous FIFOs

Download the CY7C4245 datasheet PDF. This datasheet also covers the CY7C4425 variant, as both devices belong to the same 64/256/512/1k/2k/4k x 18 synchronous fifos family and are provided as variant models within a single manufacturer datasheet.

Description

The CY7C42X5 are high speed, low power, first-in first-out (FIFO) memories with clocked read and write interfaces.

All are 18 bits wide and are pin/functionally compatible to IDT722X5.

The CY7C42X5 can be cascaded to increase FIFO depth.

Features

  • High speed, low power, first-in first-out (FIFO) memories.
  • 64 x 18 (CY7C4425).
  • 256 x 18 (CY7C4205).
  • 512 x 18 (CY7C4215).
  • 1K x 18 (CY7C4225).
  • 2K x 18 (CY7C4235).
  • 4K x 18 (CY7C4245).
  • High speed 100 MHz operation (10 ns read/write cycle time).
  • Low power (ICC = 45 mA).
  • Fully asynchronous and simultaneous read and write operation.
  • Empty, Full, Half Full, and Programmable Almost Empty/Almost Full status flags.
  • TTL compatible.
  • Retransmit.
