    Setting value of CY7S1061GE30 for TI hercules EMIF interface.

    youngmin_3838941

      Dear Cypress,

       

       

      I am checking the CY7S1061GE30 that is entered into Custom B/D with TI hercules rm48x.

       

      In order to use this SRAM, I need to set correct values into EMIF register.

       

      Below captured screen is TI Halcogen HMI which generates HAL(Hardware Abstraction Layer) code.

      I'm trying to find below values (ASYNC1 Timings : W_SETUP, W_STROBE, W_HOLD, R_SETUP, R_STROBE, R_HOLD).

       

      The clock is set as 100 MHz now. so I assume that 1 cycle is 10 ns.

       

      Even though, I've checked AC switching Characteristics of your datasheet,

      I didn't catch which value is correct for  below setting.

       

      Because all values of AC switching Characteristics are less than 10 ns.

      So it seems that below values are filled as 0 or 1.

       

      For your reference, Let me attached EMIF document.

       

      Could you kindly guide me how I calculate these?

       

      Thank you.
