Advantages And Disadvantages Of Microcontrollers


The advantages of microcontrollers are as follows:

  • Flexibility Microcontrollers are special types of processor chips that are very small and somewhat flexible, due to their programmable nature.
  • Faster Speed of Execution Since microcontrollers are fully integrated inside the processor, i.e., a “computer on a chip,” these devices operate at faster speeds to execute instructions compared to general purpose microprocessors.
  • Inexpensive As microcontrollers are fully integrated onto one chip, these devices are cheap to manufacture. Usually, microcontrollers have much lower specifications than low-power consumer-grade general-purpose microprocessors, making them even easier to mass produce.
  • Rigid Once microcontrollers are programmed, typically they cannot be reprogrammed, if microcontrollers are controlled by Read-Only Memory (ROM) only rather than Random Access Memory (RAM) .
  • Labor Saving Many tasks can be performed by microcontrollers repetitively and human efforts can be saved. The programmable nature of these devices also allows manufacturing robots to reproduce these motions very quickly and consistently, increasing productivity.


The advantages of microcontrollers are as follows:

  • Complex Architecture Microcontrollers have more complex architecture than microprocessors. Therefore, understanding their functionality is quite difficult.
  • Development Time Due to complexity of the circuit board, the development time of a microcontroller increases and cost increases.
