Difference between Microprocessor and Microcontroller

A Microcontroller (MCU) is considered a small computer that has an inbuilt Ram, ROM, processor, I/O ports, and much more. These are used to control devices automatically. MCU’s contain single Integrated Circuit (IC) that are designed and used for specific applications. MCU’s usually operate at lower speeds, around the 1MHz to 200 MHz range. These controllers are designed and embedded inside other devices to consume less. A Microprocessor consists of the Control processing unit (CPU), ALUs, and Registers on a single integrated circuit. These processors are generally used to design to be a supercomputer. The computational power for the microprocessor is very high, which allows performing complex tasks. The power consumption and dissipation are high because of the external devices, it requires cooling devices externally.  

• The microcontroller is less costly compared to Microprocessor.
• The speed of the Microprocessor is 4 GHz compared to the speed of its microcontroller is 200Mhz.
• The microprocessor has more power consumption compared to the microcontroller.
• Microcontrollers are used to handle real-time task-oriented devices independently, whereas microprocessors are dependent on many other components.
