MICROCONTROLLER
, Microcontroller
• A microcontroller is a small and low-cost
microcomputer, which is designed to perform
the specific tasks of embedded systems like
displaying microwave’s information, receiving
remote signals, etc.
• The general microcontroller consists of the
processor, the memory (RAM, ROM, EPROM),
Serial ports, peripherals (timers, counters), etc.
, Difference between Microprocessor and Microcontroller
Microcontroller Microprocessor
Microcontrollers are used to execute a Microprocessors are used for big
single task within an application. applications.
Its designing and hardware cost is low. Its designing and hardware cost is high.
Easy to replace. Not so easy to replace.
It is built with CMOS technology, which Its power consumption is high because it
requires less power to operate. has to control the entire system.
It consists of CPU, RAM, ROM, I/O ports. It doesn’t consist of RAM, ROM, I/O ports.
It uses its pins to interface to peripheral
devices.
, Applications of Microcontrollers
Microcontrollers are widely used in various
different devices such as −
• Light sensing and controlling devices like LED.
• Temperature sensing and controlling devices
like microwave oven, chimneys.
• Fire detection and safety devices like Fire
alarm.
