I was wondering what the major components of an MCU are.

I assume from that answer that you have a lot more experience with analog electronics than with embedded devices. That was sparse and incomplete. Really - you wouldn't consider a port to be significant?
hazzer answered what you would find from a board-level perspective.
Naming the parts of the microcontroller itself can be subjective.
[Snip a lot]Most microcontroller data sheets contain this information in their introductory sections.
I, on the other hand, must assume that you were never taught what's considered main components.Hint: Stuff that might vary from one controller to the next doesn't count as main parts, however crucial they may be to one particular controller.Sure, ports are significant, I should have mentioned them, only the correct term in such a context is I/O.
But yeah, my brush with anything digital is a short one, I first got around to digital when TTL was all the rage and the micros was 8080, 8085 and the very much thinking ahead COSMAC.

Doesn't make them considered main components of an MCU (which means _any_ MCU, when no specific is mentioned).
