A microcontroller is a small and low-cost microcomputer, which is designed to perform the specific tasks of embedded systems like displaying microwave’s information, receiving remote signals, etc.
The general microcontroller consists of the processor, the memory (RAM, ROM, EPROM), Serial ports, peripherals (timers, counters), etc.
Difference between Microprocessor and Microcontroller
The following table highlights the differences between a microprocessor and a microcontroller −
| Microcontroller | Microprocessor |
|---|---|
| Microcontrollers are used to execute a single task within an application. | Microprocessors are used for big applications. |
| Its designing and hardware cost is low. | Its designing and hardware cost is high. |
| Easy to replace. | Not so easy to replace. |
| It is built with CMOS technology, which requires less power to operate. | Its power consumption is high because it has to control the entire system. |
| It consists of CPU, RAM, ROM, I/O ports. | It doesn’t consist of RAM, ROM, I/O ports. It uses its pins to interface to peripheral devices. |
