ELSMC501- APPLY BASIC MICROCONTROLLER
Introduction
A microcontroller is an electronic device belonging to the microcomputer family.
These are fabricated using the VLSI technology on a single chip. There are
microcontrollers available in the present market with different word length starting
from 4 bit, 8 bit, 64 bit to 128 bit.
In a broader sense, the components which constitute a microcontroller are the
memory, peripherals and most crucially a processor. Microcontrollers are present in
devices where the user has to use a degree of control. They are designed and
implemented to execute a specific function such as displaying integers or
characters on an LCD display module of a home appliance. Application of
microcontrollers is many. In simpler terms, any equipment which has to deal with
the functions such as measuring, controlling, displaying and calculating the values
consist of a microcontroller chip inside it. They are present in almost all the present
day home appliances, toys, traffic lights, office instruments and various day-to-day
appliances.
