CY7C1570KV18

Overview

  • 72-Mbit density (4M × 18, 2M × 36)
  • 550 MHz clock for high bandwidth
  • Two-word burst for reducing address bus frequency
  • Double data rate (DDR) interfaces (data transferred at 1100 MHz) at 550 MHz
  • Available in 2.5 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
  • Synchronous internally self-timed writes
  • DDR II+ operates with 2.5 cycle read latency when DOFF is asserted HIGH
