Ethernet switches target vehicle networks

NXP Semiconductors N.V. has released the new S32J family of high-performance Ethernet switches and network controllers, extending its  NXP CoreRide platform for software-defined vehicle (SDV) development. The platform integrates NXP’s S32 compute, networking and system power management with middleware, OSes and other software from automotive software providers, Tier-1 suppliers and integration service providers.

The CoreRide platform provides production-ready building blocks for SDV architectures. Enabling greater flexibility and scalability, the S32J family uses a common switch core, NXP NETC, with NXP’s latest S32 microcontrollers and processors. This allows them to operate together as one expanded virtual switch, NXP said, simplifying integration and software re-use with other solutions in the CoreRide platform and offering re-configurable networking choices.

The S32J features 80 Gbits/s bandwidth and dual Arm Cortex-R52 cores to meet different application requirements. Port-interface speeds range from 10 Mbits/s to 10 Gbits/s. These devices meet time-sensitive networking (TSN) automotive standards and provide ASIL-D safety, hardware security engine (HSE) and MACsec ports for mixed-critical data traffic. The embedded HSE provides hardware-accelerated protection for sensitive data streams, including post-quantum cryptography. These devices also support PCIe Gen 4 for high-bandwidth and low-latency connectivity to host SoCs.

The NXP CoreRide platform with the S32J family provides production-grade networking solutions with pre-integrated software and tooling, including a software enablement kit for HSE and MACsec security, TSN stacks and remote configuration and monitoring capabilities. A virtual development kit for the S32J family will be available by the end of 2024. The solution will be available to OEMs and Tier-1 suppliers in 2025.
