Revolutionary Ethernet Technology for Seamless Automotive Connectivity

In a groundbreaking move, automotive designers are revolutionizing how legacy gateway subsystems operate. By leveraging cutting-edge technology, these innovators are migrating applications to an Ethernet network, enabling easy access to information from the edge to the cloud. Leading the charge in providing automotive-qualified Ethernet solutions, Microchip Technology (Nasdaq: MCHP) has announced the launch of its pioneering automotive-qualified Ethernet PHYs. The LAN8670, LAN8671, and LAN8672, a family of 10BASE-T1S devices with AEC-Q100 Grade 1 qualification, are set to transform the automotive landscape.

With a keen focus on functional safety and ISO 26262 compliance, the LAN8670/1/2 10BASE-T1S Ethernet PHYs are primed for use in demanding automotive applications. What sets these devices apart is their ability to seamlessly integrate low-speed devices, which traditionally required separate communication systems, into a standardized Ethernet environment. This breakthrough simplifies automotive applications and paves the way for enhanced connectivity between sensors, actuators, and the cloud, creating an all-encompassing Ethernet architecture.

The advantages of leveraging the LAN8670/1/2 extend beyond connectivity. Allowing multiple Ethernet PHYs to connect to a standard bus line makes the implementation of automotive applications more streamlined and cost-effective. With reduced cabling and switch ports, implementation costs are significantly diminished.

Moreover, the LAN8670/1/2 empowers network edges to communicate effortlessly with the broader network infrastructure using Ethernet and Internet Protocol (IP). Advanced PHY diagnostics equip users with troubleshooting capabilities, while sleep/wake functionality ensures optimal power efficiency.
Key specifications of the 10BASE-T1S devices include 10 Mbps, half-duplex mode, flexible topology with multidrop bus line, and point-to-point capabilities, all achieved through a single balanced pair of conductors. These devices also boast enhanced electromagnetic compatibility/electromagnetic interference (EMC/EMI) performance. Time-Sensitive Networking (TSN) support enables synchronized timing across extensive Ethernet networks, which is crucial for various applications throughout automotive zonal architectures.

Microchip’s instrumental role in collaborating with the Institute of Electrical and Electronics Engineers (IEEE) to develop automotive-qualified 10BASE-T1S technology cannot be understated. This revolutionary technology simplifies system design by expanding Ethernet’s reach to devices traditionally situated at the network’s periphery.

As the automotive industry embraces digital transformation, Microchip Technology remains at the forefront, ushering in a new era of seamless connectivity and standardized Ethernet architecture. With its automotive-qualified Ethernet PHYs, Microchip is driving innovation that will shape the future of automotive technology.
