Microcontroller
1. A microcontroller is a compact integrated circuit designed to govern a specific operation in an embedded system.
2. A microcontroller is a computer present in a single integrated circuit which is dedicated to perform one task and execute one specific application.
A microcontroller contains memory, programmable input/output peripherals as well a processor. Microcontrollers are mostly designed for embedded applications and are heavily used in automatically controlled electronic devices such as cellphones, cameras, microwave ovens, washing machines, etc.
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.
