The NXP SJA1105SELY is an automotive-grade Ethernet switch IC controlled over an SPI host interface. It complies with IEEE 802.3 standards and is qualified to AEC-Q100, making it suitable for in-vehicle networks that must survive under-hood temperatures from -40°C to 125°C. The 159-LFBGA package (12x12 mm) keeps the footprint compact for ECU integration.
