Things are increasing in the car of the future Electric mobility and autonomous or automated driving the need for fail-safe electrical and electronic systems. Infineon now presents an important new development for the automated vehicle. The Aurix Microcontroller of the second generation (TC3xx) were the first embedded safety controllers worldwide to receive certification for the highest functional safety level in cars (ASIL D) according to the latest version of ISO standard 26262 from SGS TÜV Saar.

The standard describes a globally binding procedure for the development and production of safety-critical systems in vehicles, as is required in automated driving. The current version has been in effect since December 2018. It has replaced the original version from 2011.

"We defined the second-generation Aurix security architecture when the new version of ISO 26262 was not yet available," says Peter Schäfer, Vice President and General Manager Automotive Microcontroller at Infineon. “Nevertheless, it meets all the requirements for an ASIL-D safety controller for automated driving.

The basis is our holistic one Security approachwhich is reflected in a sophisticated, robust architecture. The second-generation Aurix microcontrollers provide the security and contribute to the confidence required to bring automated driving to the road, ”continued Schäfer.

Computing platforms for automated driving rely on Aurix

The Aurix family from Infineon has long been successful in safety-related applications. Computing platforms for automated driving rely on Aurix as the safety host controller. In addition, the microcontrollers are used for processing sensor data in radar systems, engine and operating controls, brakes, airbags and Steering, central Gateways, domain control units or hybrid and electric cars.

Key Technologies for Faster Implementation of Autonomous Driving

Next to the Automotive-Area, the product family is getting stronger in others too safety-critical applications in demand, for example in commercial vehicles and in robotics. For this reason, Infineon is planning certification according to IEC 61508 in the next step. This is a cross-industry, fundamental standard for functional safety that serves as the basis for application-specific standards.

Aurix TC3xx devices have up to 6 processor cores, each with a 300 MHz clock frequency. Up to four of them have an additional lockstep core. With around 3000 DMIPS, Aurix sets the standard among computing controllers for computing power for implementing ASIL-D security. There is also a distributed memory protection system and secure internal communication buses. In addition, the security controller allows the integration of software with different security levels from different sources. This allows multiple operating systems and applications such as Brakes, steering, airbag and Driver assistance systems host for the autonomous, self-driving, automated vehicle on a common platform.

Second Aurix TC3xx family announced

Infineon recently launched the second Aurix TC3xx family for a wide range of applications in the distribution market started. The company offers extensive hardware and software support to enable customers to implement it quickly and efficiently. In addition to entry-level kits and evaluation boards, there are a number of application kits. The Aurix Development Studio is a free toolkit for software development and testing. In the Aurix forum, developers can exchange ideas with one another.
