Hi, The operating voltage of the PIC18F452 is 2 to 5.5V's. normally, the microcontroller operates at the 5V, when we supply 3.3V to the uc, it will still operate depend on what type of application is. just read its DataSheet...

PIC works from 2.4V to 5.5V, so it should work for 3.3V. Check the Brown Out reset configuration bits in the configuration registers if it resets. Change the brown out reset to 2V.
