Thus each instruction will be executed within the microcontroller at a quick speed. The microcontroller chip is a high-speed device, but as compared with a computer it is slow. The dominant part of microcontrollers being used nowadays is implanted in other apparatus. And these are well suited for long-lasting battery applications. Microcontrollers are used in many consumer electronics, car engines, computer peripherals, and test or measurement equipment.

Microcontrollers usually must have low-power requirements since many devices they control are battery-operated. Analog to Digital and Digital to Analog conversion.A few microcontrollers may utilize four-bit expressions and work at clock rate frequencies, which usually include: A microcontroller is a small, low-cost, and self-contained computer-on-a-chip that can be used as an embedded system.
