CY7C1643KV18

Overview

  • 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 systems
  • Data valid pin (QVLD) to indicate valid data on the output
  • Single multiplexed address input bus latches address inputs for read and write ports
  • Separate port selects for depth expansion
