A microcontroller is distinguished from a microprocessor by the fact that it integrates all necessary components like a CPU, memory, and input/output peripherals onto a single chip, making it a self-contained unit, while a microprocessor only provides the central processing unit and requires external components for memory and I/O functions; essentially, a microcontroller is a "computer on a chip" while a microprocessor is just the processing core.
