CY7C1518KV18 - 72-Mbit DDR-II SRAM Two-Word Burst Architecture

Features

  • 72-Mbit density (4M × 18, 2M × 36).
  • 333 MHz clock for high bandwidth.
  • Two-word burst for reducing address bus frequency.
  • Double data rate (DDR) interfaces (data transferred at 666 MHz) at 333 MHz.
  • Two input clocks (K and K) for precise DDR timing.
  • SRAM uses rising edges only.
  • Two input clocks for output data (C and C) to minimize clock skew and flight time mismatches.
  • Echo clocks (CQ and CQ) simplify data capture in high speed systems.
  • Synchronous in.
