CY7C1304DV25 - 9-Mbit Burst of 4 Pipelined SRAM

Features

  • Separate independent Read and Write data ports.
  • Supports concurrent transactions.
  • 167-MHz Clock for high bandwidth.
  • 2.5 ns Clock-to-Valid access time.
  • 4-Word Burst for reducing the address bus frequency.
  • Double Data Rate (DDR) interfaces on both Read and Write Ports (data transferred at 333 MHz) @167 MHz.
  • Two input clocks (K and K) for precise DDR timing.
  • SRAM uses rising edges only.
  • Two output clocks (C and C) ac.
