36-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency) with ODT

特性

  • 36 Mbit density (2 M × 18, 1 M × 36)
  • 550 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 1100 MHz),工作频率 550 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
    • SRAM 仅使用上升沿
  • 回波时钟(CQ 和 CQ)简化高速系统中的数据采集

功能描述

The CY7C2268KV18, and CY7C2270KV18 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 (CY7C2268KV18), or 36-bit words (CY7C2270KV18) 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.
