A Microcontroller is a small computer on a
single integrated circuit containing a processor core,
memory,
and programmable input/output peripherals. also often included
on chip, as well as a typically small amount
of RAM. Microcontrollers are designed for
embedded applications, in contrast to the microprocessors
used
in personal computers or other general purpose
applications.
Microcontrollers are used in automatically
controlled products and devices, such as automobile engine
control systems,
implantable medical devices, remote controls
. By reducing the size and cost compared to a
design that uses a
separate microprocessor.
Microcontroller Advantages:
·
They have small size .
·
They can be programmed .
·
They contain processor ,RAM,ROM,I\O.
