Microprocessor is an integrated circuit that only has PROCESSOR (i.e. CPU – CENTRAL Processing Unit) inside it and requires RAM, ROM, peripheral devices such as keyboard, seven-segments etc. to be externally interfaced to it. MICROCONTROLLER, on the other hand, has IO (Input/Output) ports, FIXED amount of RAM and ROM in addition to a processor on the chip. Microprocessor is generic device that can be used for any purpose but microcontroller is task-specific and can only perform the task for which it has been designed.
