CY7C1550KV18 - 72-Mbit DDR II+ SRAM Two-Word Burst Architecture

Download the CY7C1550KV18 datasheet PDF. This datasheet also covers the CY7C1548KV18 variant, as both devices belong to the same 72-mbit ddr ii+ sram two-word burst architecture family and are provided as variant models within a single manufacturer datasheet.

Features

  • 72-Mbit density (4M × 18, 2M × 36).
  • 450-MHz clock for high bandwidth.
  • 2-word burst for reducing address bus frequency.
  • Double data rate (DDR) interfaces (data transferred at 900 MHz) at 450 MHz.
  • Available in 2.0 clock cycle latency.
  • 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.
  • Data valid pin (QVLD) to indicate valid data on the output.
  • Synchro.
