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?

You can do that, but 5V powered digital sensor should be connected to SIO pins of PSoC5 instead of general GPIO.
