Marvell's automotive Ethernet unit is being sold to Infineon for 2.5 billion US dollars. The electronics supplier is thus strengthening its system competence for modern E/E architectures. The acquired part is to be integrated into Infineon's existing Automotive Division. The transaction is expected to be completed in the course of 2025, subject to the necessary approvals.

The acquired business includes physical transceivers, switches and bridges from Marvell's Brightlane portfolio. These components enable data transmission within vehicle networks - currently at up to ten gigabits per second. The technology is used in modern vehicle systems, for example for assistance systems or wireless software updates. According to Infineon, the acquired division supplies more than 50 car manufacturers, including eight of the ten largest worldwide. For the 2025 calendar year, sales of 225 to 250 million US dollars are expected.

Combining Ethernet products with microcontrollers

With this acquisition, Infineon is combining its existing Aurix microcontroller portfolio with network components that are required for software-based vehicle architectures. They form the basis for modern E/E architectures consisting of central processing units, zones and endpoints. The focus here is on central computing units, zone control units and connected endpoints that need to exchange large amounts of data securely and in real time.

By combining Marvell's automotive Ethernet portfolio with its own Aurix microcontroller family, Infineon hopes to create a comprehensive offering that includes both communication solutions and real-time control. According to Infineon, in addition to automotive technology, there are also points of contact in other technical fields of application, such as robotics. Similar requirements for data transmission and real-time processing could exist there. Further cost synergies are expected through the bundling of research and development activities and in the area of production. (sp)
