SJA1105SELY

SJA1105SELY is a 5-port automotive safe and secure automotive gigabit Ethernet switch. It switches with improved security-related features, extended interface options, and ISO 26262 ASIL-A compliance. It is a 5-port automotive Ethernet switch supporting IEEE Audio Video Bridging (AVB) and Time-Sensitive Networking (TSN) standards. Each of the five ports can be individually configured to operate at 10/100/1000Mbit/s. This feature provides the flexibility to connect any Fast/Gigabit/optical PHY or MCU/MPU to any of the ports. The new frame white/blacklisting, port-reachability and address learning restriction features improve switch security by limiting data processing to known frames and data sources and preventing the forwarding of erroneous or malicious data. The updated MII/RMII/RGMII interfaces offer extended IO voltages such as 1V8 and 3V3 RGMII.
