MICROCONTROLLER Basically a microcontroller is a device which

MICROCONTROLLER Basically, a microcontroller is a device which integrates a number of the components of a microprocessor system onto a single microchip and optimized to interact with the outside world through on-board interfaces; i. e. it is a little gadget that houses a microprocessor, ROM (Read Only Memory), RAM (Random Access Memory), I/O (Input Output functions), and various other specialized circuits all in one package.

Aplikasi Microcontrollers adalah sangat luas dan mencakup berbagai kebutuhan elektronik, seperti: Sistim management engine otomotif, keyboard PC, alat ukur elektronik (digital multimeters, frequencysynthesisers, dan oscilloscopes), printer, Televisions, radios, CD players, perangkat tape recording, Hearing aids, Security alarm systems, fire alarm systems, and building services systems
