CY7C1268XV18, CY7C1270XV18: 36-Mbit DDR II+ Xtreme SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency)
36-Mbit DDR II+ Xtreme SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency)
- 36-Mbit density (2 M × 18, 1 M × 36)
- 633 MHz 时钟实现高带宽
- 2 字突发降低地址总线频率
- 双数据速率 (DDR) 接口（数据传输速率 1266 MHz），工作频率 633 MHz
- 可提供 2.5 时钟周期延迟
- 两个输入时钟（K 和 K）用于精确 DDR 定时
- 回波时钟（CQ 和 CQ）简化高速系统中的数据采集
- 数据有效引脚 (QVLD) 表示输出上的有效数据
- DDR II+ Xtreme 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

The CY7C1268XV18, and CY7C1270XV18 are 1.8 V synchronous pipelined SRAMs equipped with DDR II+ architecture. DDR II+ 包含一个带有先进同步外围电路的 SRAM 内核。用于读和写的地址被锁止在输入 (K) 时钟的备选上升沿。Write data is registered on the rising edges of both K and K. Read data is driven on the rising edges of K and K. Each address location is associated with two 18-bit words (CY7C1268XV18), or 36-bit words (CY7C1270XV18) that burst sequentially into or out of the device.
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
Reliability and business continuity are of utmost importance for us. Hence, we remain fully committed to honoring existing customer and distributor relationships. This includes offering the legacy Cypress product portfolio. We thank you very much for your trusting support.
