CY7C1668KV18 CY7C1670KV18 144-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency) 144-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency) Features - 144-Mbit density (8 M × 18, 4 M × 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 - Operates similar to DDR I device with one cycle read latency when DOFF is asserted LOW - Core VDD = 1.8 V ± 0.1 V; I/O VDDQ = 1.4 V to VDD[1] - Supports both 1.5-V and 1.8-V I/O supply - High-speed...
