Study on effect experiment of ESD EMP to single chip microcontroller

Choosing 8031 minimal systems, a familiar MCS-51 series SCM (single chip microcontroller), as experimental object, this-paper studies irradiation field effects & effecting mechanism of ESD EMP (electrostatic discharge electromagnetic pulse) via effecting experiment and theory research respectively. The interference & damage threshold of SCM in different, failure modes are ascertained. By analyzing the failure reasons, some rules of ESD EMP effects are concluded. This paper serves to provide practical SCM designs with a thorough and heady reference in dealing with complex-ESD protection design for automatic control equipment
