PROBLEM TO BE SOLVED: To provide a microcontroller capable of ensuring the safely of a system by predicting a runaway before starting of it. SOLUTION: This microcontroller has a delay detecting means M4 for detecting that a delay time of components exceeds a prescribed value, and a safety ensuring mans M5 for performing a process for ensuring the safety of the aforementioned system by the detection of the delay detecting means. Since the process for ensuring the safety of the system is performed before the delay time of the components of the microcontroller exceeds the prescribed value deviating from the operation guaranteeing range of the components, and it comes into the state where a runaway of the microcontroller begins, the safety of the system is ensured. |
