You must always be confused when you are asked about difference between microprocessors and microcontrollers. Microcontrollers are generally used in projects and applications that require direct control of user.

As it has all the components needed in its single chip, it does not need any external circuits to do its task so microcontrollers are heavily used in embedded systems and major microcontroller manufacturing companies are making them to be used in embedded market. A microcontroller can be called the heart of embedded system.
Above is architecture of microcontroller. And you can see all the required components for a small project is present in a single chip.
When to Use Micro Processors vs. Micro Controllers
It may be called heart of a computer system. Some examples of microprocessor are Pentium, I3, and I5 etc.
As now you are basically aware of what is a microcontroller and microprocessor, it would be easy to identify the major differences between a microcontroller and microprocessor.
As all the peripheral of microcontroller are on single chip it is compact while microprocessor is bulky.
In addition the applications made with microcontrollers are cheaper because they need lesser external components, while the overall cost of systems made with microprocessors are high because of the high number of external components required for such systems.
Processing speed of microcontrollers is about 8 MHz to 50 MHz, but in contrary processing speed of general microprocessors is above 1 GHz so it works much faster than microcontrollers.
While in microprocessors generally there is no power saving system and also many external components are used with it, so its power consumption is high in comparison with microcontrollers. Tasks performed by microcontrollers are limited and generally less complex. While task performed by microprocessors are software development, Game development, website, documents making etc.
Microcontrollers are based on Harvard architecture where program memory and data memory are separate while microprocessors are based on von Neumann model where program and data are stored in same memory module. Hello Sir, Your article is awesome and I got it all.
