probably - avoid cutting slots in it and there might be sense in locating
some app-notes on how to make an "island" for the CPU and laying out,
filtering & shileding for industrial equipment; motor drives and arch

The lower the clock frequency, the lower the current consumption and the
more embedded (i.e. the smaller the size), the more quiet your circuit will
be.
This does not mean that it cannot be disturbed by external EMI. Just that it
does not emit much.
