With Infineon AURIX TC397XM MCU
TT Tech Auto MotionWise Platform Integration
First-generation solution adopted in 25 vehicles since launch

Infineon Technologies and TTTech Auto, a company specializing in autonomous driving safety platforms, announced on the 15th that they are providing a second-generation fully integrated automotive safety solution for autonomous driving use cases.
The solution is based on Infineon's AURIX TC397XM microcontroller and TTTech Auto's MotionWise safety software platform and supports Level 2 to Level 4 and 5 autonomous driving, enabling customers to accelerate time-to-market, improve software integration and validation, and reduce overall costs.

The first generation solution, based on Infineon's microcontroller and TTTech Auto's safety software platform, is at the heart of zFAS, the centerpiece of the Audi A8's piloted driving. TT Tech Auto has adopted Infineon's AURIX microcontroller TC397XM for its proven MotionWise safety software platform, supporting up to Level 5 autonomous driving.

Based on ASIL-D safety hardware, the second-generation solution is ideal for safety-critical applications. It offers enhanced ISO 26262 ASIL-D computing performance, a richer peripheral set, and advanced security features. MotionWise delivers fail-operational* performance and safety across the entire platform, with the highest ASIL level design. Each application running on MotionWise is encapsulated, allowing applications with different safety and real-time requirements to coexist and interact in a safe environment. This enables seamless application integration.

The two companies have gained extensive experience through close collaboration with major automotive companies on long-term mass production projects. Since the first-generation solution began mass production in 2017, it has been adopted in more than 25 vehicle models. Several customers have already reviewed the second-generation solution and decided to adopt it in their production ADAS systems in 2019.

“The second generation of Infineon’s AURIX microcontrollers is designed to deliver the highest levels of safety and performance required by the automotive industry,” said Peter Schäfer, Vice President and responsible for Infineon’s Automotive Microcontrollers. “MotionWise was designed with safety in mind and features maximum scalability, seamless integration and deterministic real-time behavior.”

He continued, “By combining the two, we will maximize value for customers and contribute to the accelerated implementation of advanced autonomous driving.”

“Safety is a crucial element for Level 3, 4 and 5 autonomous driving,” said Dr. Stefan Poledna, co-founder and member of the Management Board of TT Tech Auto. “The combination of TT Tech Auto’s MotionWise and Infineon’s AURIX microcontrollers enables our customers to address extremely demanding safety issues more easily.”
