A typical MCU won't have serious protection but some security processors
will, including ones that aren't very expensive because they're intended
for use in high-volume applications like payment cards.  A very
determined and high-resource attacker will be hard to stop, especially
if they can get their hands on lots of individual units.  But you can
make it pretty hard.  Today's smart cards evolved over a many-year
technical arms race between cable TV companies and cable pirates.  These
days the smart card manufacturers seem to have the upper hand, though
maybe the advantage will flip again some day.

The book "Security Engineering" by Ross Anderson is now somewhat dated,
but it's good reading about this type of subject.
