It's largely a matter of semantics and technical nit-picking,
but everyone has their own ideas about what's a microprocessor
chip and what's a microcontroller chip. to make things more
complicated, it seems every market-research firm uses its own
definition, so you can't even compare projections from two different
firms.
I tend to count them together, but if you're a stickler, here's
the most common definition: microcontrollers have on-chip RAM
or ROM, which allows them to run standalone (without extra memory
chips).
