On AURIX TC4x, a hypervisor can add another option: run multiple operating systems or AUTOSAR stack instances on one MCU, separating their execution in time and memory. That can help consolidate ECU functions, but the exact software, safety evidence and supported AUTOSAR releases depend on the selected MCU derivative and supplier configuration.
What you need to run AUTOSAR on an AURIX MCU
AURIX is Infineon’s automotive microcontroller family, not a complete AUTOSAR software package. An ECU project typically combines the MCU with a suitable AUTOSAR stack and operating system, MCAL drivers, application software, configuration and integration tools, and the safety evidence required for the intended use.
Elektrobit’s EB tresos AutoCore OS is an embedded multicore RTOS that implements AUTOSAR. Infineon’s MC-ISAR supplies AUTOSAR MCAL software for AURIX; MCAL is the hardware-abstraction layer that lets AUTOSAR software use supported MCU peripherals and functions through standardized interfaces. The MCU, RTOS, MCAL and other software components must be selected and integrated for the actual derivative and project requirements.
What Infineon supplies
Infineon’s AURIX software portfolio includes MC-ISAR AUTOSAR MCAL, SafeTlib safety software, complex device drivers and data-routing software. Infineon describes the portfolio as designed around ASPICE, ISO 26262 and ISO 21434 requirements, with support up to ASIL D described for the platform. These portfolio-level statements do not establish that every item is included, suitable or certified for every AURIX configuration.

For TC4x, Infineon’s AUTOSAR product information lists support for AUTOSAR R20-11 and memory drivers in AUTOSAR R21-11. It reports 38 MC-ISAR drivers, 17 drivers with ASIL D avoidance-of-systematic-fault claims, and four complex drivers. These are published portfolio figures, not a promise that every derivative or customer delivery contains all of them.
What the AUTOSAR release figures mean
R20-11 and R21-11 identify AUTOSAR releases, not AURIX hardware generations. The TC4x listing associates R20-11 support with its AUTOSAR offering and specifically identifies memory drivers in R21-11. Do not infer from that wording that every MCAL module, OS component or complete ECU stack is available in both releases. Confirm the required module-by-module coverage and compatible software versions with the suppliers.

What a hypervisor adds
A hypervisor manages execution environments, or virtual machines, on a processor. On AURIX TC4x, Elektrobit describes its EB tresos Embedded Hypervisor as using the MCU’s virtualization features to run multiple operating systems and AUTOSAR stack instances in parallel on one microcontroller. The intended benefit is consolidation with separation: different workloads can share silicon while remaining isolated in space and time, subject to the design and configuration.
That differs from simply running an AUTOSAR OS across multiple cores. A multicore RTOS coordinates tasks and software within its operating-system model. A hypervisor can host separate operating-system instances, creating a boundary between software environments. Whether a project needs that additional layer depends on its isolation, integration, safety and resource requirements.

When ECU consolidation can help
One MCU hosting multiple environments may let an ECU team combine functions that otherwise require separate controllers. It can also isolate an update-sensitive function from other software. Elektrobit gives onboard diagnostics as an example: separating it may mean a later diagnostics update does not force repeated homologation of unrelated software. That is a potential architectural benefit, not a blanket exemption from validation, homologation or regulatory obligations; the actual impact depends on the system and applicable approval process.
Consolidation also brings trade-offs. Multiple environments share finite compute, memory and peripheral resources, and the integrated system still needs appropriate partitioning, interference analysis, safety assessment and end-to-end verification. A hypervisor is not, by itself, proof that workloads cannot interfere or that a particular ECU meets a safety target.

|---|---|---|---|
| EB tresos AutoCore OS | AUTOSAR-compliant embedded multicore RTOS | Elektrobit identifies it as an OS for AURIX TC4x; Infineon Drive Core documentation lists EB tresos 9 AutoCore OS version 6.1.275. | The version string is documentation context and may change in later releases.

What to verify before choosing a TC4x stack
Compare candidate configurations against the project’s requirements rather than choosing by product name alone. Infineon describes AURIX applications across powertrain, braking, steering, airbags, connectivity, ADAS and radar, as well as industrial motor control and signal processing; the appropriate software and evidence depend on the function and target system.
- Isolation: Determine whether an AUTOSAR multicore OS is sufficient or whether independent OS environments need hypervisor-managed spatial and temporal separation.
- AUTOSAR and MCAL coverage: Confirm the release and the exact modules, drivers and memory-driver versions required for the chosen TC4x derivative.
- Safety evidence: Request the applicable safety manuals, safety analyses, assumptions of use and integration artifacts. Match each claim to its software version, hardware target and configuration; a portfolio statement such as “up to ASIL D” is not a project-level safety case.
- Virtualization and resources: Establish which hardware virtualization features are used, how CPU time and memory are assigned, and how shared devices are accessed. Confirm that the proposed partitioning supports the required workload and interference analysis.
- Peripheral sharing: If workloads need shared devices, identify the actual sharing mechanism and supported peripherals. EB corbos describes VIRTIO for GPU, storage and network devices, but that general capability should not be assumed for every product-target combination.
- Updates and approval impact: Identify which software can be changed independently, what regression testing is needed and how the update affects the ECU’s safety and homologation evidence.
- Integration and tooling: Confirm supplier responsibilities, tool versions, configuration workflows, supported combinations and maintenance arrangements. Infineon Drive Core documentation lists EB tresos 9 AutoCore OS 6.1.275 as an AUTOSAR-compliant embedded multicore RTOS; treat that as a documented version pairing, not a guarantee it is the latest release.
How to approach an AURIX AUTOSAR design
- Start with the target: Select the AURIX family and specific derivative against the ECU’s performance, safety and peripheral needs. Do not assume software coverage for one TC4x part applies to every TC4x derivative.
- Define the software architecture: Decide which functions belong in an AUTOSAR environment and whether they should share one OS or run in separate environments under a hypervisor.
- Map AUTOSAR releases and modules: Specify required AUTOSAR releases and MCAL modules, then validate the exact supplier support matrix for the target device and software version.
- Resolve safety and isolation requirements: Obtain safety documentation for the specific OS, MCAL and hypervisor configuration. Define partition boundaries, shared-resource policies and the evidence needed to justify them.
- Align tools and integration versions: Confirm compatible versions of configuration tools, OS, MCAL, hypervisor and partner software. The Drive Core documentation’s EB tresos 9 AutoCore OS 6.1.275 reference is one published example, not a universal version requirement.
- Validate the integrated ECU: Test timing, resource use, peripheral access, update behavior and interference in the intended configuration, and complete the applicable safety and approval work for the finished system.
AURIX is an ecosystem, not a single software bundle
Infineon’s September 2025 TC4x software announcement describes production MC-ISAR AUTOSAR MCAL and safety software alongside partner offerings for AUTOSAR stacks, non-AUTOSAR operating systems, communications, security, hypervisors, middleware and tools. It also describes AURIX Drive Core as combining partner stacks with Infineon software for ADAS and powertrain, hardware virtualization, safety services and advanced communications.

That ecosystem model matters: the MCU vendor’s MCAL and safety software, an OS or AUTOSAR stack, a hypervisor and supporting tools may come from different suppliers. The project team must establish the supported combinations and integration responsibilities rather than treating “AURIX software” as one automatically compatible package.
