CY7C12681KV18 - 1.8 V synchronous pipelined SRAM

Download the CY7C12681KV18 datasheet PDF. This datasheet also covers the CY7C12661KV18 variant, as both devices belong to the same 1.8 v synchronous pipelined sram family and are provided as variant models within a single manufacturer datasheet.

Features

  • 36-Mbit density (4 M × 8, 4 M × 9, 2 M × 18, 1 M × 36).
  • 550 MHz clock for high bandwidth.
  • 2-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.
