    hello,

    just power up it with 3,3V !
    but :
    Maximum Fosc is lower than with 5V.
    Chek BOR value if you use it.
    check ADC convertions +Vref =3,3V default value
    Maximum internal voltage reference if used
    Use of Max3223 instead of Max232 for Uart
    all other parameters...depend of your application
