    PSoC5 LP - VDDA &VDDD Different Supply Voltages

    krystian.jagoda

      Hi, Can I supply the CY8C58LP with different voltage levels on VDDA (5.0V) and VDDD(3.3V)?
      I need to have 3.3V logic on GPIO while having analog peripherals on 5.0V in order to achive  4V on DAC.
      Will it work or damage the device?
      Couldn't find exact answer on datasheet, it says (in the note*) that VDDA must be greater than or equal to all other supplies. Are they connected somehow? 

      Thanks for the answer
      Best Regards
