    Usually the distinction is whether the micro is more IO oriented or more memory interface oriented. So a PIC or ARM processor which has lots of flexible IO pins will generally be called a uC, because you use it to monitor and control IO. While a PC-based processor like Pentium chip would be called a microprocessor, because its pins are mostly dedicated to the external memory interfaces, not to IO.
