    Powering Psoc 5lp at 3.3v, 5v peripheral

    chunc_1138526

      I'm looking through the data sheets on:

      If i am powering the PSOC 5lp at a lower voltage than a peripheral device, where the peripheral device can apply a greater voltage to a PSOC 5lp GPIO pin, will that harm the PSOC 5LP?

       

      For instance, if I power my 5lp at 3.3v and I attach it to a sensor, which outputs 5v digital signals, will the PSOC 5LP be able to handle a higher digital voltage than it is being powered with, provided that digital voltage is <=5v?
