I see that in general all the micro controllers (dspic33ep256) come with different pins and separate packages even if it is the same controller. Why do they prepare so many variants?
Even for packages with the same amount of I/O's there are facts to consider on choosing one or another, as for example power dissipation, pins spacing, board dimensions, etc...
