In a groundbreaking move that promises to transform the landscape of automotive connectivity, Microchip Technology has announced its latest innovation: the LAN8650/1 MAC-PHY devices. These cutting-edge components are set to redefine how automotive designers create zonal architectures in vehicles, offering a seamless and cost-effective solution for integrating low-speed devices into standard Ethernet networks.

The LAN8650/1 MAC-PHY devices bring 10BASE-T1S Ethernet technology to the forefront of automotive applications. This breakthrough technology eliminates the need for dedicated communication systems, enabling even the simplest microcontrollers without built-in Ethernet MACs to seamlessly connect to Ethernet networks. With this development, sensors and actuators can now seamlessly become part of an all-Ethernet architecture, potentially reducing the overall size and cost of automotive designs.

Matthias Kaestner, Corporate Vice President of Microchip’s automotive business, emphasized the significance of this advancement, stating, “Microchip continues to develop automotive connectivity solutions with its line of 10BASE-T1S products, providing the industry with turnkey solutions that meet customers’ requirements. This new technology will connect sensors and actuators in the physical world all the way to the cloud, enabling a seamless Ethernet architecture in vehicles, which in turn reduces development effort and time to market.”

One of the key features of the LAN8650/1 devices is their built-in Media Access Controller (MAC) and Serial Peripheral Interface (SPI). This functionality enables designers to connect a wide range of microcontrollers, from 8-bit to 32-bit, that lack a built-in Ethernet MAC to 10BASE-T1S Single Pair Ethernet (SPE) networks. This is a significant stride toward achieving an all-encompassing Ethernet architecture within vehicles.

Furthermore, these devices come equipped with Time-Sensitive Networking (TSN) support, which ensures synchronized timing across extensive Ethernet networks. This synchronization is crucial for various automotive applications, including Advanced Driving Assistance Systems (ADAS), where precise timing is essential for safety and performance.

Safety and robustness are paramount in the automotive industry, and the LAN8650/1 devices do not disappoint. They are compliant with the AEC-Q100 Grade 1 qualification standard, making them well-suited for use in harsh environments with an extended operational temperature range from -40ºC to 125ºC. Additionally, these devices are designed to meet the stringent requirements of ISO 26262 applications, reinforcing their reliability and safety.

Ethernet solutions have been gaining traction in the automotive sector, primarily due to their established security protocols that keep network systems secure. With the introduction of LAN8650/1 MAC-PHY devices, this momentum is set to surge even further. These devices facilitate the extension of Ethernet systems to the edges of automotive networks without necessitating extensive modifications or new development, streamlining the integration process.

Microchip Technology’s LAN8650/1 MAC-PHY devices represent a significant leap forward in the quest for enhanced automotive connectivity. As vehicles become increasingly complex and connected, this innovative solution paves the way for safer, more efficient, and cost-effective designs. The future of automotive connectivity has arrived, and Microchip Technology is leading the way.
