Marvell’s Brightlane full-featured MV-Q6223 and smaller MV-Q6222 automotive Ethernet switches act as central switches for all network traffic moving between zones, advanced driver-assist-system clusters, in-vehicle infotainment networks, and external gateway communications. Peak bandwidth on the larger model is 90 Gbps, more than any other auto Ethernet switch to date. Having as many as eight 10 Gbps serdes ports, the switches pass higher-bandwidth traffic aggregated by other switches in the vehicle. They have fewer ports than zonal switches but higher overall bandwidth. Time-sensitive networking features ensure reliable critical-traffic delivery. Sampling now, Marvell plans production end of 2024. The automotive industry is gradually moving to a zonal architecture, which links nearby functions with a zone Ethernet switch that aggregates local traffic. Some of that traffic must travel outside its zone. Communication between zones requires a central switch; Marvell’s chip is the first to target this need. MACSec encryption protects all traffic through all ports; dedicated hardware isolates all cryptographic and other security-related functions such as key storage. A content-addressable memory stores rules for intrusion detection. Most central traffic feeds less-safety-critical ASIL B subsystems, but some is destined for more-critical ASIL D ones as well. Marvell intends its switches primarily for ASIL B use, but they can serve for ASIL D with suitable system design.
