VCC of pic 18 =3.3 V?

i need interface pic 18F452 with xbee module
but i find probleme of interface betwen xbee and pic

if possible make VCC+3.3V for the pic

question: he stille working with3.3V

or any one give solution for this problem please
now i'am in the last month of my final project.

thank you for all
 

Re: VCC of pic 18 =3.3 V?

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 MCU will still work in 3.3V voltage.
maybe a MOS switch between POWER and MCU, set shutoff voltage = 3.3V.

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.
