    A question on Schematic of CYBLE-416045-EVAL

    ALDE_1053476

      Hello,

       

      I've downloaded the schematic of CYBLE-416045-EVAL.

      I can see that almost all signals between PSoC5LP and PSoC6 are straight connected.

      However PSoC 6 Supply Voltage is 3.3 V max while PSoC5 LP VDDIO is 5 V derived from USB Bus.

      From PSoC 6 Datasheet I can see that Max Input Voltage for any GPIO (Including OVT Inpius) is 3.6 V.

      So: is it correct to feed PSoC 6 Input Pins straight with 5 Volts Outputs of PSoC 5 LP?

       

      Thanks,

      Alfonso
