LAN8650 Image

The LAN8650 from Microchip Technology is an Automotive Qualified MAC-PHY Ethernet Controller IC that is ideal for in-vehicle networking and automotive zonal architecture, sensor/actuator networks, machine control, industrial control cabinets, building automation, and LED lighting applications. It requires an input voltage of 1.8 - 3.3 V. This AEC-Q100-qualified PoE controller combines media access controller (MAC) and Ethernet PHY technologies to enable low-cost microcontrollers, even those without an on-board MAC support, to access 10BASE-T1S networks. It streamlines Ethernet connectivity for various microcontrollers by simplifying data transfer via a single serial interface. 

This PoE controller solution's integrated 4-pin SPI interface provides a space-efficient hardware interface design that is suitable for constrained applications. It ensures efficient data communication between the station controller and the LAN8650/1 through a simultaneous transfer of transmit and receive packets, following the OPEN Alliance 10BASE-T1x MAC-PHY serial interface specification. This PoE controller is available in a surface-mount package that measures 5 x 5 mm.
