Can I use an ATmega328 alone without anything and what is the max voltage I can power the atmega328 with Okay 2 questions. If I am to replace the Arduino with an ATmega328 programmed with a standard blink on pin 13, is this configuration correct, do I still need oscillators and whatnot?



Second question is, what is the max voltage I can power the ATmega328 with without frying it? I have seen conflicting answers of this on the net. Some have said 5V while some say 6V can someone clarify?
The datasheet describes the electrical and clock requirements of the chip, and AVR042 describes the external hardware configuration required. Decoupling, analog voltages, external crystal or oscillator if required.
