The atmega328 is a very popular microcontroller chip produced by atmel. This core uses the standard arduino uno pinout and will not break compatibility of any existing code or libraries. What's different about this pinout compared to the original one is that.

Arduino hardware package for atmega8, atmega48, atmega88, atmega168, atmega328 and atmega328pb.

There are two external interrupt pins on the atmega168/328 called int0 and int1. In contrast, pin change interrupts can be activated on any of the pins. click the image to enlarge it. It is the most popular of all avr controllers as it is used in arduino boards.
