Automotive Ethernet switches boast 10Gbps routing throughput
The chips also include a differentiated switch with integrated 100BASE-T1 PHYs and cutting-edge routing and security features that can be used in large gateway applications to connect multiple domain controllers. Delivered as a monolithic die for reduced BOM cost and footprint, the 88Q5072 and 88Q6113 switches are based on the Arm Cortex-M7 architecture. They can implement advanced protocols and security software on switch, offloading the external host processor. The devices equip time sensitive networks in vehicles with added TSN features to enable low policing and filtering (IEEE 802.1Qci), and frame presumption (IEEE 802.1Qbu). The integrated L3 hardware accelerator allows multi-gigabit routing throughput up to 10Gbps without internal processor intervention. While facilitating large data transfers in vehicle networks, the devices offer efficient sleep/wake capabilities supporting TC10 standard (OPEN alliance) lowering the overall power consumption. These highly secure multi-gig Ethernet switches have been purpose-built to address the increasing risk cybercrime represents to the automotive industry. The new solutions are designed with a robust level of security features including enhanced deep packet inspection (DPI) engine and trusted boot functionality at the foundational hardware layer.
