IEC 60730 Functional Safety With dsPIC33E DSCs

Household Appliance Functional Safety DSCs for IEC 60730-Compliant Applications

Safety is a key feature in home appliance designs. The IEC 60730 safety standard defines the test and diagnostic methods to ensure safe operation of electronic controls in home appliances.

To design safe and reliable household appliances that target IEC 60730 Class B compliance, we offer a broad portfolio of IEC 60730 functional safety ready dsPIC33E Digital Signal Controllers (DSCs) that can serve as the main controller to implement:

  • Advanced control and sensor interfacing
  • Motor control
  • Digital power
  • Touch
  • Connectivity 
  • High-performance general embedded designs

Simplify Your Design Using Certified IEC 60730 Class B Diagnostic Libraries

To simplify the design and certification of safety-critical household appliances, dsPIC33E DSCs encompas the hardware safety features and a comprehensive safety ecosystem. 

  • Specialized hardware safety features to achieve safety goals
  • IEC 60730 Class B library certified by UL and verified by VDE
  • TÜV SÜD-certified MPLAB® XC16 compilers with qualification packages
  • Functional safety-qualified MPLAB development ecosystem

The Class B library contains the diagnostic tests necessary to develop your end product and get the IEC 60730 standard certification. This library for the dsPIC33E DSCs is verified by VDE and certified by UL. You can download it for free and use it with our dsPIC33E DSCs. 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 - Class B Safety Software Library for dsPIC33E DSCs describes the Class B Safety Software Library routines that are developed in accordance with the IEC 60730 Class B standard. The application note describes:

  • How the diagnostic routines can be used to detect the occurrences of faults in a single-channel microcontroller (MCU)
  • How the diagnostic routines can be readily integrated with your application to test and verify critical functionalities

In addition, the application note outlines techniques beyond Class B safety routines to test components such as external communication, timing, I/Os and analog multiplexer.
