Abstract :
The conducted RF immunity of microcontrollers is sometimes strongly frequency dependent. This paper discovers one origin of the frequency behavior of the immunity of microcontrollers against electromagnetic disturbances on oscillator pins. The behavior is explained by considering resonances in current loops through oscillator pins. The proposed theory is verified by systematically measurements.
