Infineon’s AURIX becomes ASIL-D certified according to ISO 26262:2018
Infineon Technologies AG announced that its second-generation Aurix (TC3xx) microcontrollers are the first embedded safety controllers certified to the latest version of the ISO 26262 standard. This standard describes a globally binding procedure for the development and production of safety-critical systems in cars. In December 2018, the current version of the standard replaced the original version from 2011. The certificate was issued by SGS TUEV Saar.
“This certification underpins our leadership in automotive safety,” said Peter Schaefer, Vice President and General Manager Automotive Microcontrollers at Infineon. “We defined the safety architecture of our second generation Aurix microcontrollers before the new version of ISO 26262 was even available, and yet it fulfills all requirements for an ASIL D safety controller. We have achieved this through a holistic approach to safety that resulted in a sophisticated and robust architecture. Second generation Aurix microcontrollers thus provide the safety and trust necessary to make automated driving happen.”
The company says that the Aurix family has been successful in safety-relevant applications, and that computing platforms for automated driving rely on it as their safety host controller. Furthermore, the microcontrollers are used in radar systems for processing sensor data, in engine and transmission control, brake, airbag, and steering systems, central gateways, domain control units, hybrid and electric cars, and other applications.
In addition to the automotive sector, the product family is also increasingly used for other safety-critical applications, for example in commercial vehicles and robotics. Therefore, in the next step the company is planning certification according to IEC 61508. This is a cross-industry basic functional safety standard that serves as the foundation for application-specific standards.
Aurix TC3xx devices have up to six processor cores with 300 MHz clock frequency each. Up to four of them have an additional Lockstep core. According to the company, with around 3000 DMIPS, the product family sets the bar for functionally safe computing power supporting ASIL D among safety microcontrollers. Other features include safe internal communication buses and a distributed memory protection system. Furthermore, it allows the integration of software with different safety levels from different sources. This allows multiple operating systems and applications, such as steering, braking, airbag, and driver-assistance systems, to be hosted on a common platform.
Infineon says it has now launched sales of the Aurix TC3xx family for a broad customer and application base in the distribution market. To ease implementation for customers, the company offers hardware and software support.
