description A circuit assembly for monitoring the timing behavior of a microcontroller, including: a microcontroller to drive at least one watchdog voltage generating section for a temporally defined generation of at least one monitoring voltage and to detect and read in the generated monitoring voltage at a predetermined sampling point in time; in which the at least one watchdog voltage generating section is arranged to generate the monitoring voltage that is detectable at a predetermined sampling point in time by sampling by the microcontroller, in which a monitoring voltage that is detected at the sampling point in time and lies within a predetermined voltage tolerance range indicates a fault-free microcontroller state, and a monitoring voltage that is detected at the predetermined point in time and lies outside the predetermined voltage tolerance range indicates a faulty microcontroller state. Also described is a related method.
