I've noticed that many different Microcontrollers have different "variations", or so I assume, listed in their suffix. I'm currently looking at the ATmega644. On digikey, there are 4 different kinds of DIP 644 listed: ATMEGA644-20PU ATMEGA644P-20PU ATMEGA644PV-10PU ATMEGA644V-10PU Does anyon…

uController Suffixes..
