IEC 60730 Functional Safety With PIC24F MCUs

View All Parametrics

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.

Documentation

Application Note 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

MPLAB XC DSC Compiler

The MPLAB XC-DSC C Compiler is a full-featured, optimizing compiler that translates standard ANSI C programs into Digital Signal Controller (DSC) device assembly language sources. This compiler also supports many command-line options and language extensions that allow full access to the DSC device hardware capabilities and gives users fine control of the compiler code generator.
