Chapter 1: World of Microcontrollers
The situation we find ourselves today in the field of microcontrollers has its beginnings in the development oftechnology of integrated circuits. It enabled us to store hundreds of thousands of transistors into one chip, which was a precondition for the manufacture of microprocessors. The first computers were made by adding external peripherals, such as memory, input/output lines, timers and other circuits, to it. Further increasing of package density resulted in designing an integrated circuit which containedboth processor and peripherals. This is how the first chip containing a microcomputer later known as the microcontroller was developed.

1.1 INTRODUCTION
Novices in electronics usually think that the microcontroller is the same as the microprocessor. That’s not true. They differ fromeach other in many ways. The first and most important difference in favour of the microcontroller is its functionality. In order that the microprocessor may be used, other components, memory comes first, must be added to it. Even though it is considered a powerful computing machine, it is not adjusted to communicating to peripheral environment. In order to enable the microprocessor to communicatewith peripheral environment, special circuits must be used. This is how it was in the beginning and remains the same today.

On the other hand, the microcontroller is designed to be all of that in one. No other specialized external components are needed for its application because all necessary circuits which otherwise belong to peripherals are already built in it. It saves time and space neededto design a device.

ALL THE MICROCONTROLLER CAN DO
In order to make it easier for you to understand the reasons for such a great success of microcontrollers, we will call your attention for a few minutes to the following example. About ten years ago, designing of an electronic device controlling the elevator in a multistory building was enormously difficult, even for a team of experts. Have...
