144-Mbit QDR® II+ SRAM Two-Word Burst Architecture (2.0 Cycle Read Latency) with ODT

特徴

  • Separate independent read and write data ports
  • 333-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 666 MHz) at 333 MHz
  • Available in 2.0-clock cycle latency
  • Two input clocks (K and K) for precise DDR timing
  • Echo clocks (CQ and CQ) simplify data capture in high-speed systems
  • Data valid pin (QVLD) to indicate valid data on the output
  • On-die termination (ODT) feature
  • 詳しくは、PDF をご覧ください。
     

機能説明

The CY7C2642KV18, and CY7C2644KV18 are 1.8-V synchronous pipelined SRAMs, equipped with QDR® II+ architecture. Similar to QDR II architecture, QDR II+ architecture consists of two separate ports: the read port and the write port to access the memory array. The read port has dedicated data outputs to support read operations and the write port has dedicated data inputs to support write operations. QDR II+ architecture has separate data inputs and data outputs to completely eliminate the need to “turn around” the data bus that exists with common I/O devices. Access to each port is through a common address bus. Addresses for read and write addresses are latched on alternate rising edges of the input (K) clock.

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.
