Introduction: With the accelerated adoption of software-defined vehicles and zone-based architectures, the demand for high-bandwidth aggregation, deterministic transmission, and hardware-level security in in-vehicle networks has never been greater. Marvell’s (now part of Infineon) BRIGHTLANE™ 88Q6113, as the industry’s first high-port-count, full-gigabit aggregation automotive Ethernet switch, has become a key component for central gateways and zone controllers thanks to its 11-port multi-rate capability and built-in security engine. Mingjiada Electronics has long supplied genuine, in-stock 88Q6113-B2-BYZ2A000 units, providing stable supply chain support for in-vehicle network design.
I. Product Positioning: An 11-Port Gigabit Switch Designed for In-Vehicle Aggregation
The 88Q6113 is the first-generation, high-port-count in-vehicle Ethernet switch in Marvell’s BRIGHTLANE™ series and is fully compliant with the IEEE 802.3 automotive standard. Its core purpose is to resolve bandwidth bottlenecks in multi-sensor data aggregation and backbone routing within smart cockpits and ADAS domain controllers. Based on a single-chip monolithic die architecture, the 88Q6113 integrates 11 Gigabit-capacity MAC ports, a processing engine, and a security module into a single chip, significantly reducing BOM costs and board space compared to discrete solutions.
II. Key Features: Multi-Rate Interfaces, Hardware Security, and TSN Readiness
2.1 Flexible 11-Port Multi-Gigabit Interface Configuration
The 88Q6113’s port configuration addresses a wide range of physical layer requirements for in-vehicle networks:
2 RGMII / MII / RMII / GMII interfaces for connecting to the host SoC or legacy Ethernet devices;
6 SGMII interfaces compatible with in-vehicle 100/1000BASE-T1 PHYs;
2 XFI multi-rate SerDes, supporting 1 / 2.5 / 5 / 10 Gbps, suitable for direct use with 10GBASE-T1 or high-speed backplanes;
1 PCIe Gen3 x2 (16 Gbps) or SerDes interface, providing a low-latency channel for high-speed uplink communication with the domain controller’s main chip.
This combination enables the 88Q6113 to simultaneously support 10G backbone, 1G local access, and host PCIe interconnect on a single chip, eliminating the additional latency and costs associated with multi-chip cascading.
2.2 Integrated Arm Cortex-M7 and TSN/AVB Hardware Support
The chip features a built-in 350 MHz Arm Cortex-M7 CPU and 1 MB of SRAM, enabling the AVB/TSN protocol stack to run directly on the switch without requiring an external host to participate in the scheduling of time-sensitive traffic. Supported TSN features include IEEE 802.1AS gPTP, 802.1Qav credit-based shaping, and 802.1Qbv time-aware shaping; The 88Q6113 further adds 802.1Qci flow filtering and 802.1Qbu frame preemption to ensure that critical control flows and best-effort traffic can coexist reliably on the same network.
2.3 Hardware-Level Security and Low-Power Design
In response to the increasingly severe cybersecurity threats facing in-vehicle networks, the 88Q6113 integrates a deep packet inspection engine, a denial-of-service protection engine, and trusted boot functionality at the hardware level. Additionally, the device supports the OPEN Alliance TC10 sleep/wake standard, significantly reducing overall network power consumption when the vehicle is turned off or certain nodes are in sleep mode, thereby meeting the stringent requirements for quiescent current in electric vehicles.
III. Typical Application Scenarios
3.1 Central Gateway and Backbone Routing
The 88Q6113’s 10G XFI ports and PCIe Gen3 uplink capability make it an ideal aggregation node within a vehicle’s central gateway, connecting the Ethernet backbone to the domain controller’s main SoC. The L3 hardware acceleration engine achieves routing throughput of up to 10 Gbps without the need for an external CPU, ensuring line-rate forwarding of cross-domain data flows.
3.2 Zone Controller and Zone Aggregation
In a zone-based architecture, the 88Q6113 can simultaneously connect to multiple 100/1000BASE-T1 zone nodes via its 6 SGMII interfaces and aggregate traffic to the central computing platform via 2 XFI or PCIe uplinks. Industry-leading rugged switches based on the 88Q6113 are already in use for ADAS sensor fusion and autonomous vehicle development and validation, demonstrating the chip’s maturity in safety-critical scenarios.
3.3 ADAS Sensor Data Aggregation
The 88Q6113’s full-port Gigabit capacity and low-latency switching architecture make it suitable for aggregating real-time data from multiple cameras, radar, and lidar sensors and transmitting it via high-speed uplinks to the ADAS domain controller. Marvell officially lists this as a target application for ADAS and autonomous driving data aggregation.
