SJA1105RELY

SJA1105RELY is a 5-port, safe, and secure automotive gigabit Ethernet switch. The Ethernet switch family extends the capabilities of the SJA1105 switch 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. Examples of external PHYs are the TJA1100 and TJA1102 IEEE 100BASE-T1 PHYs from NXP Semiconductors 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.
