      Green CLK 5MHz, SPI mode 0, Delay from CS Low to first hi-CLK edge is 26ns, ad the last clk edge from CS High 13ns.

      Purple CS signal

      Orange SOMI, the response from FRAM

       

      An other acquisition for view MOSI output:

      Green clk, orange SOMI, purple MOSI.

       

      The micro to speak with F-RAM is TMS570LS3137.

       

      The circuit to connect FRAM to TMS is very simple

      I verify FRAM VDD is 3.293V.

       

      Please can you help me?
