difference between micro processor and micro cntroller
--------------------------
| It is used for big applications. | It is used to execute a single task within an application. |
| Microprocessor is the heart of computer system. | It is the heart of the embedded system. |
| It is just a processor. Memory and I/O components have to be having to be connected externally. | Microcontroller contains external processor along with internal memory and I/O components. |
| Since I/O and memory connected externally, the circuit becomes large. | Since I/O and memory present internally, the circuit is small. |
| Can't be used in compact systems and hence inefficient. | Can be used in compact systems and microcontroller is an efficient technique. |
| Cost of entire system increases. | Cost of entire system is low. |
| Power consumption is high. | Power consumption is low. |
| Most of the microprocessors do not have power saving modes. | Most of the microcontrollers have power saving mode. |
| Difficult to replace. | Easy to replace. |
| Mainly used in personal computers. | Used mainly in washing machine, MP3 players. |
