If you are an Electronics Engineering student or an Electrical Engineering student then you may hear the terms Microprocessor, Microcontroller, and CPU. Most of the students have a confuse that what is the Difference between Microprocessor and Microcontroller, Difference between Microprocessor and CPU. In this article, we are going to know the Difference between Microprocessor and Microcontroller and CPU.




What is a Microprocessor?

The microprocessor is an electronic logic circuit made by semiconductor devices like transistors, diodes mounted on a single semiconductor chip. The microprocessor can perform or process various computing functions that is why it is called a microprocessor.


What is the difference between Microprocessor and CPU?

To get the answer of this question we must know about the processor. Actually, the term Processor is much known to most of the people than Microprocessor. The processor is also known as CPU(Central Processing Unit).
The Microprocessor consists of ALU(Arithmetic Logic Unit), Registers and Timing and Control unit on a single chip.

But the CPU does not consist all the above functions on a single chip. CPU is implemented more than one circuit boards.
So the Microprocessor is in many ways similar to the CPU only the difference is the Microprocessor includes all the logic circuits, including the control unit on one chip. CPU is large in size but the microprocessor is small in size. So this is the difference between Microprocessor and CPU.




What is the difference between Microprocessor and Microcontroller?


Now one thing you must know that the only microprocessor cannot perform any computing functions or you cannot use the only microprocessor to perform your tasks you must need some peripheral devices like RAM, ROM etc. When Microprocessor and other peripherals like RAM, ROM are mounted in one single chip then it is called microcontroller. This is the main difference between Microprocessor and Microcontroller.

The other differences between Microprocessor and Microcontroller are given below,






  1. The microprocessor has few bits handling instructions. But Microcontroller has many bits handling instructions.
  2. The microprocessor has less number of pins are multifunctional. But Microcontroller has more number of pins are multifunctional.
  3. The microprocessor is much faster than Microcontroller.
  4. The microprocessor-based system required more additional hardware but Microcontroller based system required less additional hardware.
