A new network solution has been introduced that enables 8-bit, 16-bit, and 32-bit microcontrollers without built-in Ethernet MACs to connect to 10BASE-T1S single-pair Ethernet (SPE) networks.

Microchip Technology Inc. (NASDAQ: MCHP) today announced the expansion of its portfolio of automotive-qualified Ethernet solutions with the introduction of a new LAN8650/1 MAC-PHY family of devices suitable for automotive applications.

The LAN8650 and LAN8651 MAC-PHYs include a media access controller (MAC) and a serial peripheral interface (SPI) for connecting to devices at the edge of the automotive network.

The LAN8650/1 devices, which have built-in MAC and SPI, allow developers to connect 8-bit, 16-bit, and 32-bit microcontrollers without built-in Ethernet MACs to 10BASE-T1S single-pair Ethernet (SPE) networks.

This allows sensors and actuators that connect digital solutions to the real world to become part of the overall Ethernet architecture, reducing the size and cost of the overall design even when connected to the simplest MCU.

“Microchip is excited to announce the launch of its 10BASE-T1S product line,” said Matthias Kaestner, vice president of Microchip’s automotive products business unit.“We are continuously developing our automotive connectivity solutions to provide the industry with turnkey solutions that fully meet our customers’ requirements,” he said. “This new technology will enable a seamless Ethernet architecture within the vehicle by connecting real-world sensors and actuators to the cloud, while also reducing development effort and time to market.”

Additionally, the device supports Time-Sensitive Networking (TSN), enabling time synchronization even over long-distance Ethernet networks. This time synchronization is crucial for various automotive applications, such as Advanced Driving Assistance Systems (ADAS).

The automotive-qualified LAN8650/1 MAC-PHY is AEC-Q100 Grade 1 compliant and supports an extended operating temperature range of -40°C to +125°C, ensuring reliable device performance even in harsh environments. Furthermore, the device is functionally safe and designed for use in ISO 26262 applications.

Ethernet solutions continue to grow in the automotive industry thanks to well-established security protocols that ensure the security of network systems. These systems can extend to the edge of the network without extensive changes or new developments.
