Ethernet IP Core for Next-Gen Automotive SoCs: Complementing CAN, LIN, and FlexRay with Scalable Connectivity

Jun. 30, 2025, Jun. 30, 2025 – 

T2M-IP a global provider of semiconductor IP Cores, announces the availability of its ASIL-Qualified Automotive Gateway/Switch/Router IP Cores, designed to support the next generation of in-vehicle networking topologies, including Zonal, Domain, and Central Gateway architectures. This advanced IP Cores deliver a high-performance, reliable, and flexible Ethernet-based network backbone tailored for evolving electronic vehicle architectures.

T2M’s new Gateway IP Cores addresses this by offering a versatile, safety-certified switch/router that seamlessly connects and routes data across heterogeneous automotive protocols such as CAN FD Controller IP, LIN BUS Controller IP, FlexRay Controller IP, and Ethernet PHY IP (10/100/1000 Mbps), with PHY support including RMII, RGMII, and others.

Modern automotive design is rapidly transitioning toward centralized computing and software-defined vehicles (SDVs). With Ethernet becoming the dominant in-vehicle communication backbone, companies require robust IP Cores that can manage the complexity of cross-domain traffic while ensuring safety, scalability, and efficiency.

Highlights of the Gateway/Switch/Router IP Core:

• ASIL-Qualified Design for functional safety compliance in safety-critical automotive applications.
• High-Speed Packet Switching and Routing at wire speed with non-blocking performance.
• Advanced Forwarding Engine with support for:
  • Static and dynamic MAC address tables
  • VLAN and IPv4/IPv6-based forwarding
  • ARP and static route management
• Multi-Layer (L2/L2+) Classification and Routing
• Quality of Service (QoS) with 8 traffic classes, credit-based shaping (CBS), strict priority, and Time-Aware Shaper (TAS) for real-time and deterministic communication.
• Multiple Queue Management for MAC/VM ports with efficient local and shared memory usage.
• Comprehensive DMA Support via AXIM interfaces for high-throughput, low-latency data movement.
• Integrated Security with support for MACsec and MKA protocols, configurable via secure HSM interfaces.

This IP core enables OEMs and Tier-1s to implement centralized or zonal network topologies that consolidate multiple ECUs into domains (e.g., Powertrain, ADAS, Body & Comfort) or zones based on physical locations. The flexible design allows deployment as a Central Gateway, Domain Controller, or Zonal Gateway, simplifying migration from traditional point-to-point networks to Ethernet-based architectures.

T2M-IP has a wide & diverse silicon Interface IP Core Portfolio, including USB, PCIe, HDMI, Display Port, MIPI, DDR, V-by-One, programmable SerDes, SD/eMMCs, and many more Controllers with matching PHYs, available in major Fabs in process nodes as small as 7nm. On request, they can also be ported to other foundries and cutting-edge process nodes.

Immediate licensing Availability: These Semiconductor Interface IP Cores are immediately available for licensing as stand-alone IP Cores or with pre-integrated Controllers and PHYs. Please submit a request on contact@t-2-m.com for more information on licensing options and pricing.
