Robustness, reliability and safety of end-products are becoming ever more important. In some application segments these requirements are formalized and mandatory, while in others this is implemented to differentiate the product and take the step from a good product to an excellent product.

The standards for functional safety depend on the market that is targeted. Many standards support multiple levels of rigorousness, which are applied depending on the likelihood and severity of the hazard. The methods of addressing hazards range from detecting single failures and putting the system into a safe state, to full redundancy where failures should not only be detected but also corrected without any interruption or degradation of service.

Functional Safety Ready Products

When safety is critical to the success of your design, you can count on our proven experience to help you meet functional safety requirements while minimizing cost and development time. Our broad portfolio of functional safety ready products includes microcontrollers, digital signal controllers, and interface and connectivity solutions that are recommended for design into your functional safety applications. Products that contain the “Functional Safety Ready” designation have been carefully selected to encompass the latest hardware safety features and support collateral to help you achieve ISO 26262, IEC 61508, IEC 60730 and IEC 62304 safety certification. We offer the following resources:

  • AEC-Q100-qualified silicon with specialized hardware safety features
  • Failure Modes, Effects, and Diagnostic Analysis (FMEDA) report to quantify the device’s fault modes via Failure-In-Time (FIT) rate distribution
  • Functional Safety Manual that provides recommendations on how the device should be used for the safest operation
  • TÜV SÜD-certified MPLAB® XC compilers and third-party certified compiler support for a fully qualified and complete development environment

The Functional Safety Manual provides details on the fault detection methods named in the FMEDA report. It includes a description of dependent failures and hardware features for detecting systematic failures, which can be used for developing diagnostic libraries. For our select product families, we also offer diagnostic software libraries that include ASIL B and ASIL C compliant libraries for ISO 26262-based automotive designs, SIL 2 compliant libraries for IEC 61508-based industrial designs, and IEC 60730 Class B compliant libraries. Third-party tools, including benchmarking software and compliance management tools (LDRA), are also available for specific devices. The MPLAB XC compilers for functional safety include all the documentation and reports needed to have a fully qualified ISO 26262, IEC 61508, IEC 62304 and IEC 60730 development environment. These packages now include classification documents.

In addition to the Functional Safety Ready controllers, we offer a wide portfolio of PIC®, AVR® and SAM microcontrollers and dsPIC33 digital signal controllers that also support IEC 60730 compliant VDE- and UL-certified Class B libraries, offering you a range of options to select a device for your household appliance design.
