Infineon details perspectives for Aurix family, Cypress takeover
There is hardly any application field in automotive electronics where Infineon's Safety microcontrollers of the Aurix family are not found. The component has now received certification for the highest functional safety requirements. eeNews Europe discussed future prospects of this product family with Infineon's CEO of Automotive, Peter Schaefer. The manager also commented on the planned acquisition of Cypress.

The microcontrollers of the Aurix family can be found in virtually all automotive applications where Functional Safety plays a role. This applies to engine and transmission controls, brake, airbag and steering systems as well as domain control units or applications in the areas of sensor fusion and cyber security. As a companion chip, the Aurixes can be found in automotive computer platforms of practically all manufacturers; in gateways, too, they often monitor the activity of the main processor.

"The Aurix microcontrollers form a fallback level in the event of conflicting calculations or failures in the higher-level domain processor. They have properties that are of great importance for safety functions - they are fully real-time capable and offer super-fast reset times after a failure," explained Schaefer.

With up to six processor cores plus four lockstep cores per package, depending on the model, they can provide a computing power of 3000 ASIL-D DMIPS. Infineon also mentions as another important aspect the possibility of integrating software from different security levels from different sources with the Aurix. This allows several operating systems and applications, such as steering, braking, airbag and driver assistance systems, to be hosted on a common platform.
