Expanding its portfolio of automotive-qualified Ethernet solutions, Microchip Technology has released its new family of LAN8650/1 MAC-PHY devices qualified for automotive applications. The LAN8650 and LAN8651 MAC-PHYs include a MAC and SPI to connect devices at the edge of automotive networks.
The LAN8650/1 devices with a built-in MAC and SPI allow designers to connect 8-, 16-, and 32-bit microcontrollers without built-in Ethernet MAC to 10BASE-T1S SPE networks. This will enable sensors and actuators that interface between the digital and the real world to become part of an all-Ethernet architecture. Connecting to even the simplest MCUs can reduce a design's overall size and cost.
"Microchip continues to develop automotive connectivity solutions with its line of 10BASE-T1S products, providing the industry with turnkey solutions that meet customers' requirements," said Matthias Kaestner, corporate vice president of Microchip's automotive business. "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."
These devices are equipped with TSN support, allowing synchronised timing across far-reaching Ethernet networks. This time synchronisation is crucial for many automotive applications such as ADAS.
The automotive-qualified LAN8650/1 are compliant with the AEC-Q100 Grade 1 qualification standard for enhanced robustness in harsh environments, including extended operational temperature range from −40C to 125C. In addition, they are functional safety safety-ready and designed for use in ISO 26262 applications.
