Abstract

As technologies development, the functionality of appliances becomes increasingly powerful, leading to a growing complexity in electrical systems. In response to the market demand for safer, smarter, and more energy-efficient appliances, a series of worldwide standards were introduced, for example UL/IEC 60730-1/60335-1. To meet the functionality demands of household appliances and obtain worldwide recognition for safety and quality, the microcontroller (MCU) must comply with the requirements of UL/IEC 60730-1/60335-1.

Texas Instruments (TI) boasts a diverse range of MCU product lines, and TI's C2000™ MCU series stands out with abundant peripheral resources, robust CPU core, and cost-effectiveness, which are widely used in appliance applications. Also, TI provides a complete and mature C2000 MCU diagnostic library to meet the requirements of the UL/IEC 60730-1/60335-1 Class B.

This application note mainly focuses on various specifications of C2000 MCUs for appliances, the software libraries compliant with UL/IEC 60730-1/60335-1. By providing insights into these aspects, this document aims to assist engineers in swiftly selecting the most cost-effective C2000 MCU design based on both system functionality requirements and UL/IEC 60730-1/60335-1 certification needs.
