Microprocessor Vs Microcontroller

Microprocessor	Microcontroller
Microprocessor is a general-purpose chip that is used to create a multi-function computer or device and requires multiple chips to handle those tasks.	Microcontroller is a highly-integrated chip that contains all the components comprising a controller.
It contains ALU, Control Unit, registers and interrupt circuit.	It contains microprocessor, memory (RAM, ROM), I/O Interfacing circuit and peripheral devices such as A/D converter, Serial I/O, timer etc.
It has many instructions to move data between memory and CPU.	It has one or two instructions to move data between memory and CPU.
It has one or two bit handling instructions.	It has many bit handling instructions.
Access time for memory and I/O devices is more.	Less access time for built-in memory and I/O devices.
Microprocessor based system requires more hardware.	Microcontroller based system requires less hardware reducing PCB size and increasing the reliability.
Microprocessor based system is more flexible from design point of view.	Microcontroller based system is less flexible from design point of view.
Less number of pins are multi-functioned.	More number of pins are multi-functioned.
Microprocessors are most commonly used as the CPU in microcomputer systems.	Microcontrollers are used in small, minimum component microcomputer system performing control-oriented activities.
Example – INTEL 8085, INTEL 8086 etc.	Example – INTEL 8051, Motorola MC68HC11 etc.
