This is a similar Microcontroller to the ATmega328P except that it has more I/Os, more Flash, more RAM and more PWM Pins. It is used in Wise Clock, Sanguino and a lot of other boards that needed just a bit more power than the 328 has.
An Arduino bootloader can be loaded onto the 644P and you can upload your code directly with your Arduino IDE.
