High-quality microcontrollers

Microcontrollers, also called single-chip computer systems, are special semiconductor chips with integrated processors and peripheral functions. These compact computer systems are considered to be particularly powerful. They often also contain program or working memory. Many microcontrollers also have programmable function blocks. These special chips are used as embedded systems in many technical devices that determine our everyday lives. For example, they are used in smartphones, televisions, ATM cards, medical technology instruments, motor vehicles, various control devices, printers, monitors, keyboards and many other devices. When choosing a microcontroller, performance, memory space, possible interfaces and expansion options are factors that determine the purchase.
