IN Brief:
- Infineon and Qualcomm have agreed a reference subsystem for Snapdragon Ride and Ride Flex computing platforms.
- An AURIX microcontroller, OPTIREG power management, and dedicated software support monitoring and safety coordination.
- Automotive Ethernet, USB, and qualified NOR Flash extend Infineon’s contribution to the central computing architecture.
Infineon Technologies and Qualcomm Technologies have agreed to develop a microcontroller-based subsystem for centralised vehicle computers built around Snapdragon Ride and Ride Flex reference platforms. The planned design combines an Infineon AURIX safety microcontroller, OPTIREG power management, and integrated software intended to coordinate high-performance automotive computing with predictable safety-related system behaviour.
Central vehicle computers bring functions traditionally distributed across multiple electronic control units into fewer, more capable processing platforms. Automated driving, driver assistance, and digital cockpit software can demand substantial processing and AI acceleration, while vehicle control and monitoring functions must still behave reliably when faults occur. The collaboration addresses the hardware and software needed around the main processor to manage those differing requirements.
Qualcomm’s Snapdragon Ride platforms supply high-performance processing for automotive workloads. Alongside those processors, Infineon’s AURIX microcontroller would monitor platform health, coordinate safety mechanisms, and support predictable, real-time control of safety-critical functions. The proposed subsystem brings that supervisory role together with supporting power circuitry, connectivity components, and firmware in the vehicle’s central computing architecture.
Safety supervision requires defined response times and fault-handling behaviour alongside central processors managing complex perception and cockpit workloads. The microcontroller must monitor specified conditions and trigger actions within the timing constraints established by each vehicle design. Integrators must therefore define fault reporting, component responsibilities, and communications between the main computing platform and its supervisory electronics.
Infineon’s OPTIREG integrated circuits provide power management for the subsystem. Stable and monitored supply rails are important in equipment that must observe the condition of processors and associated electronics as operating loads change. The collaboration also includes a dedicated software package that pre-integrates firmware for Infineon’s microcontroller with safety and monitoring software tailored to the Snapdragon reference platforms.
A common set of platform interfaces and monitoring functions could reduce integration work for carmakers and Tier 1 suppliers adopting the reference architecture. Infineon intends its software package to establish the principal interactions between the AURIX subsystem and Qualcomm’s platforms. Each finished vehicle design will still require its own hazard analysis, hardware and software validation, and safety assessment under the applicable automotive requirements.
Vehicle network integration is another part of the proposal. The software package supports connections through Ethernet and CAN, allowing supervisory and computing functions to exchange information with other vehicle systems. Infineon’s BRIGHTLANE automotive Ethernet and USB components provide further connectivity options, while its SEMPER NOR Flash memory has been qualified specifically for the Snapdragon Ride platforms.
The qualified SEMPER NOR Flash adds non-volatile storage to the Snapdragon Ride reference-platform ecosystem. NOR Flash can retain code and configuration across power cycles, making its read characteristics and data integrity relevant during boot, reset, and recovery operations. Those functions have to be coordinated with the power sequence, control software, and communication interfaces that enable the wider vehicle computer to start and operate reliably.
The AURIX architecture is designed for automotive functional safety applications, with hardware mechanisms that support fault detection and management. Infineon’s technical documentation describes a safety management unit able to gather alarm signals and configure reactions to different faults. The particular monitoring strategy and response of a finished Snapdragon-based vehicle system will depend on the selected controller, the integration work, and the application’s safety requirements.
Peter Schiefer, president of Infineon’s Automotive Division, described the reference approach as combining a powerful system-on-chip with “a safety microcontroller, power management, connectivity and memory devices”. The supporting components must operate to defined timing, power, and fault-handling requirements so that central AI processing can be supervised within the vehicle’s safety architecture.
Infineon will present its software-defined vehicle technology at electronica 2026 in Munich, including semiconductor building blocks for central computing architectures. The agreement extends the Snapdragon Ride ecosystem with reference designs and associated software for processor supervision, network interfaces, storage, and supply management. Vehicle manufacturers and Tier 1 suppliers can then evaluate how these elements fit their own electronic control and safety concepts.
The companies have established a technology agreement for the reference subsystem, with further implementation work required before it can be incorporated into production vehicle platforms. Suppliers adopting the approach will have to define fault responses, validate the interactions between supervisory microcontroller and central processor, and demonstrate that the combined electronics meet the requirements of each intended vehicle application.
