Microchip Technology (Nasdaq: MCHP) has launched its LAN866x family of 10BASE-T1S endpoint devices with Remote Control Protocol (RCP) to address connectivity challenges in automotive zonal architectures. The devices extend Ethernet connectivity to edge nodes in vehicle networks without requiring node-specific software development.

The LAN866x endpoints function as bridges that translate Ethernet packets directly to local digital interfaces. The software-less design reduces programming requirements and streamlines silicon usage. The devices support standard RCP protocols for centralized control of edge nodes and utilize 10BASE-T1S multidrop topology to enable all-Ethernet zonal architecture.

The endpoints target automotive applications including interior and exterior lighting systems, audio systems, and control functions. They bridge Ethernet data to digital interfaces that control LED drivers, transmit audio data to microphones and speakers, and manage sensors and actuators over the network.

"With the addition of these RCP endpoint devices, Microchip's Single Pair Ethernet product line empowers designers to realize a true all-Ethernet architecture for Software-Defined Vehicles," said Charlie Forni, corporate vice president of Microchip's networking and communications business unit. "We are committed to delivering innovative solutions and supporting our customers with global technical expertise, comprehensive documentation and development tools to further reduce design complexity and help them bring vehicles to market faster."

Microchip's Single Pair Ethernet solutions include transceivers, bridges, switches and development tools that enable data transmission over single twisted pair cable. The portfolio supports 10BASE-T1S, 100BASE-T1, 1000BASE-T1 and higher speed standards for automotive, industrial and building automation applications.

Microchip Technology Inc., headquartered in Chandler, Arizona, supplies semiconductors and development tools across industrial, automotive, consumer, aerospace and defense, communications and computing markets.
