    Hey every buddy,
    I want to use my ATmega128 with 3.3V input supply...

    is it possible?
    and if possible then is it great deal to save power?

    In my application i wont be able to change or charge my battery frequently so i need controller which can work on less voltage and less power supply.

    ATMEGA128 Operating Voltage is 4.5 - 5.5V
    ATmega128L Operating Voltage is 2.7 - 5.5V
    ATmega128A Operating Voltage is 2.7 - 5.5V

    at 5 Volt you can run the controller up to 16 MHz
    at 3.3Volt approximately max 10 MHz
