ISO 26262 Functional Safety-Ready PIC® and AVR® MCUs
ISO 26262 is the international standard for functional safety of electrical and/or electronic systems in road vehicles.
Designing safe and reliable automotive applications to ensure customer safety is critical. To meet these rigorous safety requirements, we offer a broad portfolio of functional safety ready PIC® and AVR® microcontrollers (MCUs) that encompasses the hardware safety features and supporting collateral to help you achieve ISO 26262 Automotive Safety Integrity Level (ASIL) B safety certification for your design. You can also achieve higher ASIL C/D safety levels through redundancy (decomposition).
Uses for Functional Safety Ready PIC and AVR MCUs
You can use our PIC18 and AVR MCUs in safety-critical embedded systems such as UI controllers for mechanical and capacitive buttons in the cabin, steering wheel, center console or as part of a keyless entry system (door handles). You can also use these devices for other safety-critical sensors and actuators such as air quality sensors and seat controls. Our affordable and easy-to-use MCUs are also highly popular as safety co-processors where the PIC18 or AVR MCU is placed next to a primary MCU/MPU to implement a safety mechanism or add redundancy to achieve higher ASIL levels through decomposition.
Supporting Collateral for Functional Safety Ready MCUs
We provide essential collateral such as ISO 26262 Failure Mode Effect and Diagnostic Analyses (FMEDA) and safety manuals for all PIC16, PIC18 and AVR MCUs. The PIC18 Q83, PIC18 Q84 and AVR DA product families are the first families to become formally ASIL B Ready-certified by SGS-TÜV Saar®, proving that these devices are highly suitable for ASIL B applications. The ASIL B Ready certification report granted by SGS-TÜV for our AVR DA family of products notes that these devices even meet the necessary SPFM/LFM metrics and PMHF value to achieve ASIL C targets, thereby passing the required performance to meet the ISO 26262 ASIL B with good margins. All automotive versions of the PIC16, PIC18 and AVR MCUs meet the AEC-Q100 Grade 1-qualified requirement.
Simplify the safety certification of your automotive designs using our ISO 26262 functional safety resources:
- ASIL B Ready-certified FMEDA
- ASIL B Ready-certified safety manual
- Functional safety diagnostic libraries (ASPICE CL3 certified)
- Development ecosystem for functional safety applications with TÜV SÜD-certified MPLAB® XC C compilers and a qualification package for the MPLAB ecosystem
Whether you are new to ISO 26262 functional safety or a seasoned expert, you can count on our proven experience and solutions to help you meet functional safety requirements while minimizing cost, risk and development time.
ISO 26262 Basic Package
Basic package includes:
- FMEDA1
- Safety manual1
ISO 26262 Starter Package
Starter package includes:
- Basic package
- Diagnostic software library1, 2
ISO 26262 Full Package
Full package includes:
- Starter package
- Certificates and reports1, 2
Notes:
- FMEDA and Safety manual for PIC18-Q84 and AVR DA are "ASIL B Ready" certified by SGS TÜV. Other FMEDAs and safety manuals use the same format and maintain the same quality. Certificates are included in the Full package.
- The software diagnostic library implements a collection of the diagnostic mechanisms described in the safety manual. Software diagnostic mechanisms not available in the library may be implemented by the system integrator.
- The software diagnostic library is APSICE CL3 certified.
Notes:
- Available through our online purchasing portal and some distributors.
Functional Safety Ecosystem
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, our MPLAB XC C compilers are TÜV SÜD-certified for several functional safety standards. We also provide the complete certification packages for our MPLAB development tools ecosystem to help you qualify your projects.
MPLAB X IDE
Organize, write, test and debug your embedded software applications in the MPLAB X IDE.
MPLAB XC Compiler
Build your embedded software with the TÜV SÜD-certified MPLAB XC8 Pro Functional Safety Compiler.
MPLAB Code Coverage
Verify and document your software test coverage with the MPLAB Code Coverage tool.
Achieving ASIL C/D Safety Level
You can typically achieve higher safety levels through redundancy. You can target ASIL C/D using multiple devices through ASIL decomposition: the combination of two MCUs allows you to more easily meet the ASIL C/D safety goals.
ASIL C = ASIL B(C) + ASIL A(C)
ASIL D = ASIL B(D) + ASIL B(D) = ASIL C(D) + ASIL A(D)
This decomposition technique is one of the reasons why PIC and AVR MCUs are often used as safety co-processors: this is a way to reduce the complexity of the safety implementation and ease the certification to get the product into the market faster. You can often reduce the cost of the end product by doing so because the total memory consumption, the effort to reach compliance and the maintenance efforts are reduced.
