Interview with Marco Cassol, Infineon
“Not everything makes sense to be centralized”
Marco Cassol has been part of Infineon since 2018.
Marco Cassol
Microcontrollers remain vital to automotive innovation. Marco Cassol from Infineon explains how MCUs evolve alongside high-performance SoCs to ensure safety, determinism, and efficiency in software-defined vehicles.
With a career spanning over a decade in automotive
electronics, Marco Cassol combines deep technical expertise with product
strategy experience. After starting out as a software engineer at Elektrobit,
he joined NXP Semiconductors, where he worked as Field Application Engineer and
later Product Manager.
Since 2018, he has been part of Infineon Technologies,
advancing through product management and marketing roles to his current
position as Senior Director Product Marketing & Management. Cassol plays a
key role in shaping Infineon’s microcontroller roadmap for advanced automotive
applications — from ADAS and safety to E/E architectures and software-defined
platforms.
At the Automotive Computing
Conference 2025, he will focus on real-time processing in the context of
high-performance SoCs and the enduring relevance of MCUs for software-defined
vehicles. In the run-up to the event, we asked him three questions about the
evolving role of microcontrollers in tomorrow’s automotive architectures.
ADT: As high-performance SoCs dominate the SDV discussion, microcontrollers still play a crucial
role. From your perspective, how are MCUs evolving to remain relevant in
increasingly software-driven vehicle architectures?
Cassol: MCUs remain the main building block of what
makes a car. They are evolving in several areas to support software-defined
vehicle architectures, including communication (for example, new communication
interfaces such as 10Base-T1S Ethernet and networking accelerators),
cybersecurity, software-over-the-air updates, multi-core architectures with
virtualization support, edge AI capabilities,
and of course a continuously advancing software ecosystem.
At the ACC 2025, you will
highlight real-time processing in the context of complex SoC environments. How
can MCUs complement high-performance compute units to ensure deterministic
behavior and system reliability?
Today, MCUs
are responsible for real-time and safety-critical functions in a car, and that
should remain the case. Across the whole E/E architecture we see MCUs
continuing to be the most cost-efficient, and in some cases the only, way to
implement safety-critical functionalities. Take, for instance, ASIL-D
applications like steer-by-wire systems with fail-operational requirements. If
this processing were moved to the central node, the entire system, including
the central computer, zone controllers, and edge ECUs, would inherit the ASIL-D
fail-operational requirements. This would add complexity, increase cost, and
ultimately raise the system vulnerability. Not only on end-point ECUs, but also
on Central computing nodes or Zone controllers – where we see for instance
vehicle motion control functions being implemented – we see that our
Microcontrollers remain the best option for implementing control algorithms or
functions which require low power consumption. Not everything makes sense to be
centralized.
Infineon has a long legacy in safety-critical automotive
electronics. How does this experience influence your approach to developing
microcontroller solutions that balance performance, efficiency, and scalability
for future SDV platforms?
As the leader in the automotive microcontroller market
and the benchmark for functional safety, scalability, and performance, we
continue to build on our strengths by offering customers a scalable portfolio
for all embedded applications. Our MCUs are used by a very large customer base
across all regions and application domains. Both traditional OEMs and Tier 1
suppliers, as well as new market entrants, rely on Infineon AURIX, TRAVEO, and
PSoC microcontrollers to build their E/E architectures, drive their powertrain
systems, control their chassis and body systems, and ensure the safety of their
ADAS platforms with deterministic behavior. We leverage the extensive know-how
gained from this broad market exposure to continuously evolve our products.
