    What do I do with the Die attach pad?

    Hi guys,

    Nooby question here, should be pretty straightforward.

    I'm building a teensy powered device of my own and am currently creating an eagle component for the MKL02Z32VFG4 bootloader chip.
    What on earth do I do with the Die attach pad on the bottom?
    I'm guessing I want to connect it to to the board to disperse heat but should it be connected to ground or am I wrong entirely?

    Many thanks,

    Giga.

    You should have a look at the data sheet. But normally, these "die pads" should be soldered to a ground plane, or in case of a multilayer board to a copper area which is linked to a ground plane with 3 or 4 vias.

    Connect it to GND.

    Heat isn't an issue with that chip. It uses very little power.

    The center pad is needed only for mechanical stability on this part.
