IEC 60730-1 Class B+IEC 60335-1
The International Electrotechnical Commission (IEC) has established safety standards for the normal operation of household appliances. These standards provide recommendations for both hardware and software solutions and encompass key IEC standards related to functional safety, namely IEC 60730-1 and IEC 60335-1. These standards pertain to functional safety in household appliances and similar environments. Depending on the application, these standards categorize functional safety into several safety classes.
Within these safety standards, various testing and diagnostic methods are defined to ensure the secure operation of embedded control hardware and software for household appliances. The standards cover the mechanical, electrical, electronic, EMC, and abnormal operation aspects of appliances. Based on the application context, these standards are divided into three safety classes:
Class A: Not intended to ensure the safety of equipment (e.g., humidity control devices, timers, lighting control, timed switches, etc.).
Class B: Intended to prevent unsafe operation of controlled devices (e.g., thermal cut-off devices, preventing unsafe operation of washing machines, dishwashers, dryers, refrigerators, freezers, and cooking utensils, etc.).
Class C: Intended to prevent specific hazards (e.g., automatic combustion controllers and sealed water heaters, etc.).
For the majority of household electrical applications, B-class functional safety protection is required. The B-class standard for microcontrollers is related to both hardware and software. Components that comply with this standard can be divided into two groups: MCU-related and application-related. The application-related part depends on the customer's application structure and needs to be defined and developed by the user based on product application requirements (e.g., communication, IO control, interrupts, analog input and output, etc.).
MindMotion Arm Cortex-M0 Core Microcontroller's Self-Diagnostic Library
MindMotion's Arm Cortex-M0 core microcontroller's self-diagnostic library is designed for 32-bit microcontrollers in the MM32 Cortex-M0 series. It provides Class B self-checking functions, including tests for CPU registers, program counters, clocks, non-volatile memory (Flash memory), volatile memory (SRAM), and other items defined in IEC 60730-1 Appendix H. MindMotion's Arm Cortex-M0 Core Microcontroller's Self-Diagnostic Library is integrated into the customer's application as a library file, making it easy to port and helping users reduce the development time for self-checking functions and accelerate the certification process. For further information, please contact MindMotion.
Since its establishment in 2011, MindMotion has consistently adhered to high standards and strict requirements for independent research and development of software, hardware, and ecosystems. Through its MindMotion Automotive Chip Testing Verification Laboratory, which complies with international automotive electronic component reliability standards (AEC-Q100/AEC-Q104), it has established an efficient and comprehensive project management process.
In the future, MindMotion will continue to uphold the spirit of "integrity, commitment, innovation, and cooperation" and develop and improve self-diagnostic libraries for various core products, continuously providing users with higher-quality products and services.
