(Summary description)Smart home appliances have entered countless households, and the safety of home appliances is crucial. As smart home appliances integrate more functions, their system complexity becomes increasingly complex - integrating various types of separate ICs to achieve electronic control, advanced display and other functions. How to ensure the safe operation of embedded control hardware and software for smart home appliances? Recently, the HK32C030/C005/C105/C207/R78X series products of the Hang Shun chip have passed the IEC 60730 certification, providing a functional safety library that meets the Class B standard, reducing the time and cost of terminal product safety certification for smart home appliance manufacturers, helping to shorten product launch time, and improving product stability and security from the bottom layer. IEC 60730 certification certificate Security is the life of smart home appliances! International Electrotechnical Commission: IEC 60730 "Gold Standard" The International Electrotechnical Commission has developed the IEC 60730 standard to define various safety testing and diagnostic methods that can detect system faults in a timely manner and eliminate the risk of harm. When this standard is applied to the design of white goods and other appliances, it can improve the safety of smart home appliances. IEC 60730 divides the safety standards for microcontrollers based household appliances into three categories: •Class A: Control functions unrelated to device safety Application scenarios: temperature and humidity control, lighting control, etc •Class B: Intended to prevent unsafe operation of controlled equipment Application scenarios: washing machines, refrigerators, etc •Class C: Intended to prevent special hazards, such as preventing equipment explosions Application scenarios: automatic burners, gas dryers, etc Typical household appliances, such as white batteries, need to comply with Class B protection, which includes monitoring or detecting key components such as CPU registers and program counters, interrupt processing and execution, system clock frequency, and memory detection. This can effectively prevent harm to household appliances caused by unsafe operations, such as the electric door lock of the washing machine and the motor thermal shutdown mechanism. Hangshun HK32MCU provides a complete functional safety library to assist customers in achieving functional safety design Home appliance manufacturers can embed the certified HK32MCU security program library into the entire system software to achieve self detection function, and then apply for IEC 60730 functional safety standard certification for the final product. Under normal circumstances, the program will start with a reset and go through the green box to complete all functions, including the startup configuration of the application app, the execution of the Main function, and the execution judgment of multiple interrupts. In order to achieve the safety function of IEC 60730, we have added a blue section in the program, which includes module safety startup detection after reset and runtime cycle detection. At the same time, we have added a failure judgment interface, as shown in the overall flowchart of the functional safety software. The startup detection includes: CPU startup detection Detection of watchdog startup Flash startup detection RAM startup detection Clock start detection Detect when control flow starts The runtime cycle detection includes: CPU runtime detection Stack boundary runtime overflow detection System clock runtime detection Flash CRC runtime detection Control flow runtime detection Watchdog refresh during runtime RAM runtime detection (performed in interrupt service program) Overall flowchart of functional safety software The development of emerging technologies such as 5G, artificial intelligence, and the Internet of Things is accelerating the iterative upgrading of smart home appliances, and also bringing significant momentum to the sustained growth of the smart home appliance market. The Hang Shun chip HK32MCU has the characteristics of low power consumption, high reliability, and high compatibility, which can provide more differentiated product performance and cost advantages for home appliance products, and has become the best choice for many home appliance manufacturers.

IEC 60730 divides the safety standards for microcontrollers based household appliances into three categories:
•Class A: Control functions unrelated to device safety
Application scenarios: temperature and humidity control, lighting control, etc
•Class B: Intended to prevent unsafe operation of controlled equipment
Application scenarios: washing machines, refrigerators, etc
•Class C: Intended to prevent special hazards, such as preventing equipment explosions
Application scenarios: automatic burners, gas dryers, etc
Typical household appliances, such as white batteries, need to comply with Class B protection, which includes monitoring or detecting key components such as CPU registers and program counters, interrupt processing and execution, system clock frequency, and memory detection.
