With white goods and industrial appliance safety now regulated by the IEC, choosing the right microcontroller is more important than ever to market success. Motor drives, white goods, and other appliances that could be unsafe to operate if one or more of their mechanical or electronic components fail are now subject to the testing and qualification requirements of the International Electrotechnical Commission (IEC). The IEC 60730 standard covers mechanical, electrical, electronic, EMC, and abnormal operation of ac appliances.
