What are the Features of a microcontroller?

  • Far more economical to control electronic devices and processes as the size and cost involved is comparatively less than other methods.
  • Operating at a low clock rate frequency, usually use four bit words and are designed for low power consumption.
  • Architecture varies greatly with respect to purpose from general to specific, and with respect to microprocessor, ROM, RAM or I/O functions.
  • Has a dedicated input device and often has a display for output.
  • Usually embedded in other equipment and are used to control features or actions of the equipment.
  • Program used by microcontroller is stored in ROM.
  • Used in situations where limited computing functions are needed
