How could you get a PIC to totally fry itself when a certain instruction was
executed?  I understand that it would probably require some external
hardware, but where is it most easy to burn it out.  I think the chip can
handle alot of voltage most ways and I guess the best way would be to use a
charge pump circuit and when a gate is active it would send a jolt through
the MCU making it not function anymore.  Even erasing the memory is good,
but that would probably require more parts.

Whats the general idea on this?
