Marvell’s second generation secure automotive Ethernet switch, 88Q5050, is an 8-port Ethernet gigabit capacity switch that is fully compliant with IEEE802.3 automotive standard and utilizes advanced security features to guard against hacking and denial of service (DoS) attacks.
The 8-port Ethernet switch offers 4 fixed IEEE 100BASE-T1 ports, and a configurable selection of an additional 4 ports from 1x IEEE 100BASE-T1 port, 1x IEEE 100BASE-TX, 2x MII/RMII/RGMII ports, 1 GMII port, and 1 SGMII port. The switch off ers local and remote management capabilities, providing easy access and configuration of the device.

This switch employs the highest hardware security features that are designed at the root source of Marvell’s secure automotive Ethernet Switch to prevent malicious attacks or compromises to the data streamed in the vehicle. This advanced switch employs deep packet inspection (DPI) techniques and Trusted Boot functionality to deliver industries most secure automotive Ethernet switch. The switch supports both blacklisting and whitelisting addresses on all its Ethernet ports to further enhance its security.
