고출력 전자기파에 의한 마이크로컨 트롤러 소자의 민감성 분석과 보호 방안

초록

Modern electronic circuits are of importance for the function of communication, traffic systems and security systems. An intentional threat to these systems could be of big casualties and economic disasters. This paper had known damage effect and protection plan of microcontroller device with coupling caused by UWB-HPEM (Ultra Wideband-High Power Electromagnetic). The UWB measurements were done at an Anechoic Chamber using a RADAN　UWB voltage source, which can generate a transient impulse of about 180kV. The susceptibility level for microcontroller has been assessed by effect of various operation line lengths. The results of susceptibility analysis has showed that the effect of the reset line length on the MT(Malfunction Threshold) is larger than the effect of the different line length(Data, Power, Clock). With the knowledge of these parameters electronic system can be designed exactly suitable concerning the system requirements, Based on the results, susceptibility of micro controller can be applied to protection plan to elucidate the effects of microwaves on electronic equipment.
