In February 2026, Infineon Technologies AG partnered with BMW AG to supply MCUs, BRIGHTLANET Ethernet connectivity solutions, power management, and smart power switches for BMW’s Neue Klasse platform.

In January 2026, TEXAS INSTRUMENTS INCORPORATED showcased its automotive 10BASE-T1S PHY product range at CES 2026. This enables multidrop and point-to-point 10 Mbps single-pair Ethernet for sensor networks and zone or edge-node architectures.

NXP Semiconductors is expanding its automotive networking IP by developing high-performance automotive Ethernet switches and PHYs, such as the S32J family and broad Ethernet portfolio that support various data rates and TSN, integrated with its S32 and CoreRide platform to simplify zonal software-defined vehicle networks for OEMs and Tier-1s.

Robert Bosch GmbH continues to advance its role as a protocol innovator, evolving CAN technology (e.g., CAN XL) and expanding central gateway/vehicle communication nodes that connect CAN, LIN, and Ethernet to support high-bandwidth data exchange and secure, cross-domain functions in connected and autonomous vehicles.

Infineon Technologies AG is enhancing its software-defined vehicle capabilities through the acquisition of Marvell’s Automotive Ethernet business, combining leading AURIX microcontrollers with Ethernet PHYs, switches, and bridges to provide end-to-end high-bandwidth, secure communication stacks for future E/E architectures.

STMicroelectronics’s strategy emphasizes broad automotive-grade transceiver and MCU portfolios that support CAN, LIN, and Ethernet, combined with long-term protocol availability commitments and integrated security features such as virtual LAN support on Ethernet controllers, to meet OEM longevity and safety requirements.

TEXAS INSTRUMENTS INCORPORATED specializes in scalable automotive connectivity solutions by integrating in-vehicle networking technologies such as 10BASE-T1S Ethernet PHYs (extending Ethernet to edge nodes) and CAN-FD controller/transceiver system basis chips alongside high-performance compute and radar ICs tailored for centralized/autonomous vehicle networks.

Market Ranking

The automotive communication protocol market is consolidated, with five main players holding 31–36% of the total market share. NXP Semiconductors focuses on strengthening its leadership in automotive communication by expanding its automotive Ethernet switches and PHYs integrated with the S32 platform, enabling zonal and software-defined vehicle architectures with built-in safety and security. Infineon Technologies pursues an end-to-end in-vehicle networking strategy by combining its AURIX microcontrollers with advanced automotive Ethernet PHYs and switches, reinforced through the acquisition of Marvell’s automotive Ethernet business to support high-bandwidth, safety-critical E/E architectures. TEXAS INSTRUMENTS emphasizes scalable in-vehicle connectivity by expanding its CAN FD, LIN, and 10BASE-T1S automotive Ethernet solutions that extend Ethernet to edge nodes while optimizing power efficiency and EMC performance for centralized and zonal vehicle networks. The remaining 64–69% of the market is shared among other regional and emerging players, contributing to extensive competition and offering opportunities for smaller players to establish a footprint.
