That's indeed kind of strange. The ATmega644A has two UARTs (as the smaller 324P and 164P always had), while the ATmega644 has only one. I think that's the major difference. Sure, it's a drop-in replacement nevertheless, but using the same device IDs is confusing, for sure. -- cheers, J"org .-.-. --... ...-- -.. .
