CY7C1562XV18/CY7C1564XV18 72-Mbit QDR® II+ Xtreme SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency) 72-Mbit QDR® II+ Xtreme SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency) Features - Separate independent read and write data ports - Supports concurrent transactions - 450 MHz clock for high bandwidth - Two-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 2.5 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 - Single multiplexed address input bus latches address inputs for both read and write ports - Separate port selects for depth expansion - Synchronous internally self-timed writes - QDR™-II+ Xtreme operates with 2.5 cycle read latency...
