    Separate analog and digital power supply for PSoC-4M

    user_418894472

      Hi!

         

      I was wondering whether is it possible to connect (VSSA and VDDA) to a different supply voltage other than that is being used for (VSSD and VDDD).

         

      Also is it possible to connect VSSA to a slightly negative voltage, say -200mV as compared to VSSD which is referenced 0V for digital peripherals.

         

      The configuration would look like:

         

      VDDD = 3.3V

         

      VSSD = 0V

         

      VSSA = -0.2V

         

      VDDA = 3.1V  (VDDA-VSSA = 3.3V)

         

      Thanks
