2nd Generation AURIX Microcontroller Safety Verified with ISO 26262
Includes 4 lockstep cores operating at a 300MHz clock frequency

In response to the recent increasing demand for automotive functional safety and electrical and electronic systems for e-mobility, ADAS, and connected cars, Infineon Technologies has launched the second-generation AURIX (TC3xx) microcontroller.
It replaced the initial version released in 2011 with an embedded safety controller that has received the highest level ASIL D certification according to the latest version of the ISO 26262 standard.

The AURIXt TC3xx devices include up to six processor cores, each operating at a clock frequency of 300 MHz. Four of the six cores have additional lockstep cores. With 3000 MIPS performance, they set a new standard for functional safety computing performance for ASIL D support among safety microcontrollers.

In addition, AURIX, featuring a secure internal communication bus and a distributed memory protection system, can integrate software even if security levels vary by vendor. This allows multiple operating systems and applications, such as steering, braking, airbags, and driver assistance systems, to be hosted on a common platform.

The AURIX product family is used in various safety-critical applications, and AURIX is being adopted as a safety host controller in major computing platforms for autonomous driving. It is used in a wide range of applications, including sensor data processing for radar systems, engine and transmission control, braking, airbags, steering systems, central gateways, domain control units, and hybrid and electric vehicles.

As the use of AURIX microcontrollers expands into safety-critical applications such as commercial vehicles and robots, Infineon plans to obtain certification under IEC 61508.

Peter Schaefer, General Manager of Infineon Microcontrollers, said, “Infineon had already defined the safety architecture for the second-generation AURIX microcontrollers before the new version of ISO 26262 was released,” adding, “The second-generation AURIX microcontrollers provide the safety and reliability that enable autonomous driving.”
