Microcontrollers
which are generally referred to as single chip computers are used for designs
that require computer intelligence but do not need the disk drives, keyboard
and full screen display of a desktop computer. For some simple designs, a
microcontroller with perhaps a keypad, a small display and solid state memory
(no disk drives are often used with less expense and smaller size)

Generally,
a microcontroller is referred to as a self contained computer since the
processor, memory and input/output are all contained in a single package. Its
basic functions involve performing of arithmetic logic, data-moving and program
branching. These are the functions that are commonly used in many applications.
The ability of the microcontroller is accessed by writing a program that
performs the desired functions.

Microcontrollers
differ from one another in architectures, features, mode of operating and
packaging. All microcontrollers are members of families in which many of the
hardware features available are presented in different combinations. Hence, microcontrollers
version are chosen for use consider the one best suited for your system
requirements.

Micro
controllers are also characterized by the number of bits of data they can
process at once; with a higher number of bits indicating a faster and more
powerful clip. Earlier microcontrollers were manufactured using bipolar or NMOS
technologies while all modern devices are fabricated using CMOS technology
which decreases the current chip size
and the power requirement considerably

In
the design of a microcontroller-based instrument, virtually all design
decisions are affected by the microcontroller chosen.
