ADI's 10BASE-T1S E2B™ Transceivers

2024-10-25

The automotive industry is transitioning to zonal architecture, which is redefining connectivity based on physical location rather than functions of ECUs in the car. This change reduces the number of ECUs and eliminates up to 1 kilometer of harness cable, while also opening the opportunity of separating hardware and software for a service-oriented architecture (SOA).

Automotive is rapidly becoming a major consumer of Ethernet devices, the widespread rollout of Ethernet in vehicles drove the specification of IEEE 802.3 10BASE-T1S Ethernet technology. 10BASE-T1S which now offers a compelling alternative to traditional bus systems such as CAN, CAN FD, LIN, and FlexRay for edge node connectivity as it also offers a bus topology which is different to all the other Automotive Ethernet standards.

ADI recognized early on that further innovation was possible to help aid the rollout of this technology. ADI developed the E2B technology to accelerate the adoption of 10BASE-T1S by providing a solution that simplifies the networking of sensors and actuators by providing a product that eliminates the need for microcontrollers in edge sensor and actuator nodes. Now all edge nodes can be a complete hardware implementation with all software centralized which aligns directly with the move to SDV.

The E2B Software layer along with sensor actuator low level drivers can now run on a zonal controller or central processing high performance control unit connected through Ethernet switches. ADI’s proprietary E2B Transport Protocol provides a highly optimized solution for direct sensor and actuator connectivity across Ethernet networks.

By centralizing software, E2B reduces the burden of maintenance and development, making it easier to manage and update systems, overall reducing the Bill of engineering materials. It greatly aids the Automotive trend of Software Defined Vehicles. This approach allows for seamless OTA updates, ensuring that customers can provide continuous improvements and new features to their end-users without the need for physical interventions.
