Functional Safety for ISO 26262, IEC 61508, IEC 60730 and IEC 62304
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.
ISO 26262 (ASIL): Functional Safety for Automotive Applications
Automotive Safety Integrity Levels (ASIL A, ASIL B, ASIL C and ASIL D) for electrical and electronic systems used in series production road vehicles, excluding mopeds
IEC 61508 (SIL): Functional Safety for Industrial Applications
Safety Integrity Levels (SIL 1, SIL 2, SIL 3 and SIL 4) for safety-critical electrical and electronic systems used in industrial applications
IEC 60730: Functional Safety Standard for Household Appliances
Class A, Class B and Class C levels for automatic controls in equipment designed to operate in households
IEC 62304: Functional Safety for Medical Devices
Class A, Class B and Class C levels for the safety and effectiveness of medical device software and software life cycle processes
Functional Safety Ready Products
When safety is critical to the success of your design, you can count on Microchip’s 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, IEC61508, 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 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.

Development Ecosystem for Functional Safety Applications
When you are designing functional safety applications, using development tools that meet the requirements of safety standards can make it easier for you to create compliant systems. To help you with implementing system-level functional safety in your applications, we have adopted safety standards for the MPLAB® development ecosystem including our TÜV SUD-certified MPLAB XC compilers.
Our third-party partners also offer safety-certified compilers and tools supporting many of our products.
Functional Safety Design Partners
Whether you are new to functional safety or a seasoned expert, your safety development and certification can be often be accelerated by involving functional safety design partners early in your project. Our Functional Safety Design Partners have demonstrated their knowledge of functional safety and can assist you with developing projects according to the requirements of the standards.
