Motor drives, white goods, appliances, and other equipment can become unsafe to operate if one of their components fail. These equipments are subject to the testing and qualification requirements of the International Electrotechnical Commission (IEC). Specifically, the IEC 60730-1 “Automatic electrical controls for household and similar use” safety standard. Similar practices are followed in the United States leveraging UL 1998 “Safety Software in Programmable Components.”
The aspects most relevant to microcontrollers (MCUs) are IEC 60730 Annex H and UL 1998 Annex A.2, which detail the diagnostic test requirements to support safe function of home appliances.
This document provides a high-level overview of these specifications as applied to an MCU and describes how C2000™ functional safety features can be leveraged to meet the diagnostic test requirements.

Motor drives, white goods, appliances, and other equipment may become unsafe to operate if one of their components fail. These equipments are subject to the testing and qualification requirements of the International Electrotechnical Commission (IEC). Specifically, the IEC 60730-1 standard covers automatic electrical controls for household and similar use.
Although compliance to IEC 60730 is attained at a system level, understanding the correct criteria for choosing a microcontroller is important to achieve compliance. The use of electronic components such as microcontrollers (MCU) is addressed by Table H.1 in Annex H of IEC 60730 "Requirements for electronic controls". Annex H specifies acceptable diagnostic techniques and measures applicable to an MCU in order to support the safe function of equipment.
While IEC 60730 is primarily used in Europe, similar practices are followed in the United States leveraging UL 1998 “Safety Software in Programmable Components.” Table A2.1 in Appendix A, provides examples of acceptable measures for microelectonic hardware failure modes that are consistent with the requirements of IEC 60730 Table H.1. These requirements are derived from the IEC 61508 standard, “Functional safety of electrical/electronic/programmable electronic (E/E/PE) systems.”
