Microcontroller units (MCUs) are single-chip computers optimized for performing embedded computing tasks like controlling a ...

Many microcontrollers include timer circuits, but only a few include a battery-backed real-time clock (RTC). Yet many applications require an RTC, which you can easily add by using a 1-Wire network.

Electronic Control Units of safety critical systems require constant monitoring of the hardware to be able to bring the system to a safe state if any hardware defects or malfunctions are detected.
