About Infineon's safety concept

AURIX™ was developed as a safety element out of context (SEooC) fulfilling the applicable objectives of ISO 26262:2018 up to ASIL-D. The customer benefits of AURIX™ PRO-SIL™ safety and security microcontrollers include:

supporting the development of applications with ISO 26262:2018 certification
supporting protection against random faults as described in the safety manual
accelerating the development of safety critical applications via software libraries

PRO-SIL™ highlights

Broad hardware portfolio, including sensors and microcontrollers, along with analog and power management ICs that provide SIL-supporting features
An independent functional safety management organization supports the ISO 26262 safety integrity level
Safety documentation, such as the safety manual, safety analysis summary report, and ISO 26262 certification, can be made available for dedicated PRO-SIL™ products (NDA may be required)
Infineon offers expert system integrator support for achieving the required ASIL on system level
Infineon’s PRO-SIL™ logo will guide you to our products (hardware, software, and safety documentation) with SIL-supporting features.

Infineon’s activities result in simplified integration in safety-related applications.

Functional safety microcontrollers: ISO 26262

ISO 26262 defines automotive systems' development for functional safety integrity and reducing hazards from failures. Safety requirements depend on ASIL ratings, ranging from ASIL-A to ASIL-D. Critical systems like steering or braking have ASIL-D rating, demanding utmost safety due to potentially fatal consequences. New parts with safety goals follow ISO 26262-compliant flow for direct use in safety-relevant applications. Pre-ISO 26262 devices may be used in compliant systems, requiring evidence of suitability and failure modes analysis. Infineon assists customers in achieving high ASIL levels by supporting existing microcontrollers' qualification and offering fully ISO 26262-compliant MCUs for the future.

AURIX™ made for safety applications

The AURIX™ architecture is designed in accordance with an ISO 26262-compliant process to efficiently meet ASIL-D requirements. The platform uses up to four cores in a diverse lockstep architecture combined with cutting-edge safety technology, such as safe internal communication buses or a distributed memory protection system. Innovative encapsulation techniques allow the integration of software with various safety levels (QM to ASIL-D) from different sources, thereby significantly reducing system complexity. Thanks to this optimized approach, multiple applications and operating systems (such as steering, braking, airbag, and advanced driver assistance systems) are seamlessly hosted on a unified platform. Furthermore, Infineon extends the microcontroller safety roadmap with devices dedicated to the advanced driver assistance system (ADAS) segment, such as radar or camera applications. The new devices include high-speed interfaces, integrated hardware acceleration, and enhanced ECU validation and instrumentation tools. All ADAS devices support ISO 26262 safety methodology, meaning that they can be involved in automatic decisions to assist drivers, such as emergency braking
