Microchip launches new 10BASE-T1S Ethernet solution to help OEMs easily connect automotive devices

【Lansheng Technology News】Microchip Technology Inc. today announced the launch of the LAN8650/1 MAC-PHY series of new devices that meet automotive application requirements, further expanding its automotive-grade Ethernet solution product lineup. The LAN8650 and LAN8651 MAC-PHY include a media access controller and serial peripheral interface for connecting devices at the edge of the automotive network.

The LAN8650/1 device with built-in MAC and SPI enables designers to connect 8-, 16- and 32-bit microcontrollers without built-in Ethernet MAC to 10BASE-T1S single-pair Ethernet networks. This enables sensors and actuators that connect the digital and real worlds to become part of a full Ethernet architecture. Connecting to even the simplest microcontrollers reduces the overall size and cost of the design.

Matthias Kaestner, vice president of Microchip's automotive business, said: "Microchip will continue to develop automotive connectivity solutions through the 10BASE-T1S product line to provide the industry with turnkey solutions that meet customer requirements. This new technology will bring sensors and execution to the physical world. The controller is always connected to the cloud, enabling a seamless Ethernet architecture in the car, reducing development effort and time to market."

The new family of devices has built-in Time Sensitive Networking (TSN) support, enabling synchronized timing on long-distance Ethernet networks. This time synchronization is critical for many automotive applications such as advanced driver assistance systems (ADAS).

The LAN8650/1 MAC-PHY is automotive qualified and meets AEC-Q100 Level 1 certification standards for enhanced stability in harsh environments, including extended operating temperature range of -40ºC to 125ºC. These devices meet functional safety requirements and are suitable for ISO 26262 applications.

Ethernet solutions maintain strong momentum in the automotive industry due to their comprehensive security protocols to ensure network system security. These systems can be extended to the edge of the network without requiring extensive changes or new development efforts.
