Overview

CY7C1268KV18/CY7C1270KV18 36-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.
5 Cycle Read Latency) 36-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.
5 Cycle Read Latency) Features ■ 36-Mbit density (2 M × 18, 1 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 1 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 ■ HSTL inputs and variabl...
