Microcontrollers, or MCUs, are fully functional computer systems in chip form with memory and programmable peripherals built around a central core processor. Microcontroller units are fully functional compared to a microprocessor unit that has the limited functionality of a CPU only. Electronic microcontrollers include the standard logic and arithmetic algorithms of a generalized microprocessor together with data storage read-write memory, permanent data storage flash memory, program storage read-only memory, input and output interfaces, and peripherals. Microcontrollers are perfect for battery operated applications because they operate at lower speeds than microprocessors, approximately 32KHz and use very little power.
Microcontrollers automatically control applications such as remote controls, appliances, toys, office equipment, power tools and auto engines. The combined operating elements of the microcontroller shrinks the cost, size and power usage of systems that require separate input and output elements, memory and a central microprocessor. MCUs make products physically possible and economically viable purchases for mass market consumers.
1. Understand the microcontroller industry and market demands.
2. Buy from a tried and true microcontroller manufacturer.
3. Stay current on emerging electronic microcontrollers and programmable microcontroller technologies.
