[Editor's Note] The core of the SDV transition is that vehicles move from a hardware-centric to a software-centric structure and become integrated based on a central computing foundation. This facilitates OTA updates and feature expansion, enabling the continuous evolution of vehicles. The increasingly complex electronic structure is addressed by a zone-based architecture, allowing OEMs to achieve reductions in wiring, weight, and cost, as well as improved development efficiency. In body networks, 10BASE-T1S is gaining attention as a practical technology for Ethernet transition, and when applying it, the MCU's Ethernet processing and security capabilities are key criteria. The Infineon TRAVEO™ T2G is an MCU that balances performance, power, and scalability, while the CYT3AB5 complements the portfolio as a product specialized in 10BASE-T1S. Accordingly, we met with Infineon's General Manager Song Byeong-cheol to hear about the technological changes resulting from the transition to SDV and Infineon's competitiveness.


■ The biggest architectural change with the transition to SDV is

The biggest change in SDVs is that the vehicle shifts from a hardware-centric to a software-centric model.

In the past, ECUs were separated by function, but now, with integration based on a central computing foundation, the entire vehicle can be operated like a single software platform.

As a result, OTA updates and the addition of new features become much easier, and the vehicle can continuously evolve.

■ Reasons for Moving from Domain-Based to Zone-Based Architecture and OEM Benefits

The biggest reason is that as vehicle structures become increasingly complex, a simpler and more efficient architecture has become necessary.

A zone-based architecture is a method that divides vehicles into physical zones, collects signals at the zone level, and processes them centrally.

From the OEM's perspective, it can reduce wiring, weight, and costs, and significantly increase development and testing efficiency.

■ If I were to sum up the reason why 10BASE-T1S is attracting attention in SDV body networks in one word

In short, it is because it is the most realistic technology for converting the body network area to Ethernet.

SDV architecture, while providing higher bandwidth and lower latency than existing CAN or LINHe gets along well with his wife.

■ The first criterion to look at when reviewing 10BASE-T1S is

The first thing to check is whether the MCU can reliably handle Ethernet-based networks.

An important criterion for judgment is whether the MCU level can handle not only bandwidth and latency but also the Ethernet stack and security features.

■ What is TRAVEO™ T2G's biggest competitive advantage?

The strength of TRAVEO™ T2G is that it combines performance, low power consumption, and scalability in a balanced way.

It provides sufficient computational performance required for the body or zone controller, while offering excellent power efficiency and flexible system expansion through various interfaces.

■ How CYT3AB5 complements the existing portfolio

CYT3AB5 is a dedicated MCU optimized for 10BASE-T1S.

It makes Ethernet implementation in body networks and zone architectures easier and faster, and integrates seamlessly with the existing TRAVEO™ T2G portfolio.
