Household Appliance Functional Safety
The IEC 60730 safety standard defines the safety requirements for electronic controls in household appliances.
You can use our broad portfolio of PIC24F microcontrollers (MCUs) to design safety-critical household appliances that target IEC 60730 Class B compliance. Our PIC24F MCUs are IEC 60730 functional safety ready and can function as the main controller in the following designs:
- Sensor interfacing and control
- Low-power designs
- Applications requiring segmented LCD displays and USB connectivity
Simplify Your Design Using Certified IEC 60730 Class B Diagnostic Libraries
Our PIC24F MCUs encompass the hardware safety features and a comprehensive safety ecosystem to simplify the design and certification of safety-critical household appliances through:
- Specialized hardware safety features to achieve safety goals
- IEC 60730 Class B library that is certified by UL and verified by VDE
- TÜV SÜD-certified MPLAB® XC16 compilers with qualification packages
- Functional safety-qualified MPLAB development ecosystem
The IEC 60730 Class B software library contains the diagnostic tests required to design your safety-critical home appliance and get the IEC 60730 Class B certification. This library for PIC24F MCUs is verified by VDE and certified by UL. You can download it for free, to use with our PIC24F MCUs. We recommend using the Class B library with the certified MPLAB XC16 functional safety compiler. The Class B safety routines can be called periodically at startup or runtime to test:
- CPU registers and program counter
- Invariable and variable memory
- Clock
We recommend using the Class B library with the certified MPLAB XC16 functional safety compiler.

AN1778 describes the Class B Safety Software Library routines for PIC24F MCUs that are developed in accordance with the IEC 60730 Class B standard. The application note describes:
- How to detect the occurrences of faults in a single channel MCU through diagnostic routines
- How to test and verify the critical functionalities of a controller by integrating diagnostic routines directly into your application
- How to test components such as external communication, timing, I/Os and analog multiplexer
Featured Products
The PIC24F GU/GL/GP family of eXtreme Low Power (XLP) MCUs enables the development of an array of innovative home appliance applications, both with and without displays.
When you are designing functional safety applications, using development tools that meet the requirements of safety standards can make creating compliant systems easier. To help you with implementing system-level functional safety in your applications, our MPLAB XC16 C compiler is TÜV SÜD certified for IEC 60730 safety standards. We also provide the complete certification packages for our MPLAB development tools ecosystem to help your projects qualify for the certification.
- TÜV SÜD-certified MPLAB XC16 functional safety compiler
- MPLAB Analysis Tool Suite
- MPLAB X Integrated Development Environment (IDE), debuggers/programmers and related documentation and reports
