Functional Description

The CY7C1347G is a 3.3 V, 128 K × 36 synchronous pipelined SRAM designed to support zero-wait-state secondary cache with minimal glue logic. CY7C1347G I/O pins can operate at either the 2.5 V or the 3.3 V level. The I/O pins are 3.3 V tolerant when VDDQ = 2.5 V. All synchronous inputs pass through input registers controlled by the rising edge of the clock. All data outputs pass through output registers controlled by the rising edge of the clock. Maximum access delay from the clock rise is 2.6 ns (250 MHz 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.
