CY7C1143KV18 - 18-Mbit QDR II+ SRAM Four-Word Burst Architecture

Key Features

  • Separate independent read and write data ports.
  • Supports concurrent transactions.
  • 450-MHz clock for high bandwidth.
  • Four-word burst for reducing address bus frequency.
  • Double data rate (DDR) Interfaces on both read and write ports (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 sys.
