Microcontroller

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
