Automotive Ethernet switch is “key component” for high speed networks
At CES, in Las Vegas this week, NXP Semiconductors will introduce an Ethernet switch that it describes as a “key component” of vehicle networks, with high levels of performance, safety and security.
The SJA1110 multi-gigabit Ethernet switch is designed to help vehicle manufacturers deliver the high-speed networks required for connected vehicles. It is believed to be the first automotive Ethernet switch with built in safety capabilities, offering integrated 100BASE-T1 PHYs, hardware-assisted security as well as multi-gigabit interfaces. It is optimised for integration with NXP’s S32G vehicle network processor and is designed to be used with the VR5510 power management IC in vehicle networks.
It has been introduced to support the Ethernet-based web sensors, actuators and processing unit and service-oriented gateways and domain controllers required for over-the-air updates and data-driven applications in connected vehicle networks. These networks are required to be scalable and move data quickly and securely. The car networks must also deliver functional safety in case of failure.
The SJA1110 Ethernet switch is aligned to the latest tine-sensitive network (TSN) standards and offers integrated 100BASE-T1 PHYs, hardware-assisted security and safety capabilities along with multi-gigabit interfaces.
It enables customers to meet ASIL requirements and implement dedicated failure-detection mechanisms for predictive maintenance.
The SJA1110 switch processes every Ethernet frame reaching the engine control unit (ECU) by validating it against hardware-based security rules which collect statistics and can trigger escalations if something does not conform to specification.
It is available in four hardware- and software- compatible variants, with a set of NXP original software and an open integrated controller.
NXP Semiconductors enables secure connections for a smarter world and provides secure connectivity solutions for embedded applications for applications in the automotive, industrial and IoT, mobile, and communication infrastructure markets. The company has approximately 30,000 employees in more than 30 countries.
