    Why so many packages for Microcontrollers

    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?

    Why do they make different size hammers, they're all used for hitting things?

    Re: Why some many packages for Microcontrollers

    Hi,

    If there are not different packages .... then there must be one "ideal" package.
    What package is the ideal one, that fits all customer's needs?

    60 pins or 100 pins??
    that is the type of question

    do you need the extra I/O?
    if not, is it worth the trade off in board space, etc?

    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...

    Which 'same' controller in different packages are you referring to? Give one example so we can discuss the reasons properly.
