Do you know what is called the “small electronic chip” that runs your A.C., or your T.V., or your music system, or home-automation systems etc.?
These small chips are called “processors” which can be further divided into microcontroller and microprocessor and other types of processors. So, microcontrollers are the processors which controls your whole electronic system. Microcontrollers are different from Microprocessors. You can check my other post for to read the difference between microprocessor and microcontroller.
Basically “Micro-controllers” are the CPU on chip which means they have ALU (arithmetic and logical unit), RAM, ROM, input-output ports on the chip itself which makes them very easy to install in any embedded system and reduce the the whole space to a greater value. On the top of everything, microcontroller take very low power to operate.
There are many big manufacturers of microcontroller chip like Atmel, Micro-chip technology (which makes pic series of micrcontrollers) etc.
