What is Microcontrollers, Definitions Advantages & Disadvantages

Authored By: Ankita Prajapati

A microcontroller is an integrated circuit (IC) chip, which contains a processor core, memory, and programmable input/output peripherals. It is used in embedded systems i.e. in devices that require a combination of hardware and software to carry out specific tasks.

It is used to control a variety of electronic devices such as washing machines, cars, elevators, and toys.

The processor core in a microcontroller is a reduced version of a typical processor found in a personal computer.

It is smaller and consumes less power than a typical processor. The memory in a microcontroller is used to store the instructions and data required by the processor to perform its tasks.

It can also be used to store the data retrieved from the input/output peripherals.

The input/output peripherals are the devices that allow the microcontroller to interface with the outside world.

  1. Low cost: Microcontrollers are very economical and offer good performance at a low price. They are also very small in size, which makes them easier to use in embedded systems where space is a major constraint.
  2. Reduced power consumption: Microcontrollers consume very less power, which makes them ideal for battery-powered devices.
  3. High degree of integration: Microcontrollers are designed with a large number of peripherals, which makes them suitable for applications where a high degree of integration is required.
  4. Easy to use: Microcontrollers are easy to program and have a wide range of applications.


  1. Limited processing power: Microcontrollers are limited in terms of processing power and are not suitable for applications that require high-performance computing.
  2. Limited memory: Microcontrollers also have limited memory, which makes them unsuitable for applications that require large amounts of data storage.
  3. Limited input/output capabilities: Microcontrollers have limited input/output capabilities, which makes them unsuitable for applications that require a high degree of connectivity.

Microcontrollers are versatile, low-cost, and low-power IC chips that are used in a variety of embedded systems. They are ideal for applications where a high degree of integration is required and where low power consumption is necessary. However, they have limited processing power, memory, and input/output capabilities, which makes them unsuitable for applications that require high-performance computing or large amounts of data storage.
