I think microprocessers are the basic components of a microcontroller...
they are integratd to put together a uC.. :idea:

Microcontroller differs from a microprocessor in many ways. First and the most important is its functionality. In order for a microprocessor to be used, other components such as memory, or components for receiving and sending data must be added to it. In short that means that microprocessor is the very heart of the computer. On the other hand, microcontroller is designed to be all of that in one. No other external components are needed for its application because all necessary peripherals are already built into it. Thus, we save the time and space needed to construct devices.

first thing a microprocessor kit full is a microcontroller -a simple explanation.

Program memory and data memory are same of uP but different for uC
most uP uses Princeston architecture while uC's Havard

uC is application oriented while uP is just a CPU(general purpose)
