CYRS1544AV18 - 72-Mbit QDR II+ SRAM Two-Word Burst Architecture

Download the CYRS1544AV18 datasheet PDF. This datasheet also covers the CYRS1542AV18 variant, as both devices belong to the same 72-mbit qdr ii+ sram two-word burst architecture family and are provided as variant models within a single manufacturer datasheet.

General Description

The CYRS1542AV18 and CYRS1544AV18 are synchronous pipelined SRAMs, equipped with 1.8-V QDR II+ architecture with RadStop™ technology.

Cypress’s state-of-the-art RadStop Technology is radiation hardened through proprietary design and process hardening techniques.

Key Features

  • Separate independent read and write data ports.
  • Supports concurrent transactions.
  • 250-MHz clock for high bandwidth.
  • 2-word burst on all accesses.
  • Double data rate (DDR) interfaces on both read and write ports at 250 MHz (data transferred at 500 MHz).
  • Two input clocks (K and K) for precise DDR timing.
  • SRAM uses rising edges only.
  • Echo clocks (CQ and CQ) simplify data capture in high speed systems.
  • Single multiplexed address input bus latches address i.
