Difference between Microprocessor and Microcontroller They are the basic terms of an interface system that can often be confused.Get difference between microcontroller and microprocessor from screen. For those starting the course of electronics may have come across microprocessors and microcontrollers. ConclusionĮlectronics is the study that deals with the physics, engineering and applications of the movement of electronics. But since microcontrollers have fixed internal memory, it is not possible to extend the memory of a microcontroller.
Since the microprocessor has external memory, the addition of this memory is possible. 
Whereas, the clock speed of microcontroller being in the range of 8 to 50 MHz does not let it perform complex tasks. The microprocessor has a clock speed of 1Ghz and therefore can be used for performing complex tasks.
The clock speed of both these components varies greatly. 
The microcontrollers perform specific tasks in which the output depends on the inputs.
The microprocessor is used in performing general tasks like editing, games and websites where the output and the input are not relative. Since the microprocessor is the processing unit of a computer, they are used in a computer whereas the microcontrollers being a mini-computer itself, is used with embedded system for performing specific functions. The microcontroller comes with the internal controlling unit, memory and I/O components. The microprocessor only comes with an internal controlling unit and all the memory and I/O components have to be externally installed. A microprocessor is the heart of a computer system and a microcontroller is a mini-computer and is embedded to perform specific tasks. Main Differences Between Microprocessor and Microcontroller So, one can also say that microcontrollers are used in projects and other applications that require a direct user interface. They are seen to be used in a washing machine, digicam, etc.
