CY7C1338G: 4-Mbit (128 K × 32) Flow-Through Sync SRAM

2016 年 11 月 21 日

4-Mbit (128 K × 32) Flow-Through Sync SRAM


  • 128 K × 32 common I/O
  • 3.3 V core power supply (VDD)
  • 2.5 V or 3.3 V I/O supply (VDDQ)
  • Fast clock-to-output times
    • 8.0 ns (100-MHz version)
  • Provide high-performance 2-1-1-1 access rate
  • User-selectable burst counter supporting Intel® Pentium® interleaved or linear burst sequences
  • Separate processor and controller address strobes
  • Synchronous self-timed write
  • Asynchronous output enable
  • Offered in Pb-free 100-pin TQFP package
  • “ZZ” sleep mode option


The CY7C1338G is a 128 K × 32 synchronous cache RAM designed to interface with high-speed microprocessors with minimum glue logic. Maximum access delay from clock rise is 8.0 ns (100-MHz version). A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access. All synchronous inputs are gated by registers controlled by a positive-edge-triggered clock input (CLK).

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.
