NXP has developed a high-performance Ethernet switch and network controller with the same core as its automotive microcontrollers and processors.
The NETC controller core in the NXP S32J allows the non-blocking switch to operate together with a CPU as one expanded virtual switch to ease integration and software issues.
The NETC controller is a key part of the CoreRide platform and is based on the same dual ARM Cortex-R52 cores used in other CoreRide parts for ASIL-D functional safety and software compatibility. However details of the core are scarce.

The S32J provides 80Gbps bandwidth with ports ranging from 10Mb to 10Gb for software defined vehicle architectures. The S32J devices meet TSN automotive standards and provide robust ASIL-D safety, hardware security engine (HSE) and MACsec ports for mixed-critical data traffic and uses a PCI Express 4 interface.
The combination of the S32J family with the NXP CoreRide platform provides production-grade networking with pre-integrated software and tooling. This includes a complete software enablement kit for HSE and MACsec security, TSN stacks and remote configuration and monitoring capabilities.
A virtual development kit for the S32J Ethernet switch family will be available by the end of 2024 with designs available to OEMs and Tier-1 suppliers in 2025.
“The transition to software-defined vehicles requires OEMs to simplify their network architectures and reduce the software and hardware integration complexity. The S32J and NXP CoreRide networking solutions provide production-ready building blocks for these new software-defined network architectures,” said Meindert van den Beld, senior vice president and general manager of in-vehicle networking, NXP Semiconductors
This lighlights the networking partners in CoreRide such as Sonatus and TTTech Automotive. “Sonatus is a longstanding partner with NXP, with our combined technologies already in millions of production vehicles. This new NXP CoreRide networking solution deepens our support for vehicle networking and the NETC networking foundation across NXP products, enabling OEMs to accelerate development of more adaptable, upgradable architectures for software-defined vehicles,” said Dr. John Heinlein, Chief Marketing Officer at Sonatus
“At TTTech Auto, we are excited about the advancements in vehicle networking solutions through NXP’s CoreRide networking platform. The integration of scalable and dynamically re-configurable network management capabilities for TSN-based, advanced Ethernet networks is crucial for the development of software-defined vehicles (SDVs). TTTech’s MotionWise platform complements the NXP CoreRide networking solution, delivering safe and flexible communication solutions that help OEMs and Tier-1s accelerate development cycles, enhance system reliability, and enable seamless end-to-end communication across vehicle networks,” said Dr. Stefan Poledna, Chief Technology Officer and Co-founder of TTTech Auto.
