The central location for vehicle network processing is the gateway. Gateways provide segmentation of networks built with traditional vehicle interfaces such as CAN, LIN and FlexRay, or they can additionally support high-speed interfaces like 100Mbps and Gigabit Ethernet, and may provide support for over-the-air (OTA) firmware updates.
Gateways provide segmentation and some hierarchy to a vehicle network built with traditional, Kbps/Mbps class interfaces such as LIN and CAN, and in some cases, first generation automotive Ethernet at 100Mbps. Gateways are typically implemented using automotive microcontrollers, with programmable intelligence via ~100 MHz class 32-bit processor cores.
NXP® provides around half of all network connections found in a new car; our solutions deliver scalability, re-usability, and performance that manufacturers demand. In-Vehicle Networking (IVN) systems and the central gateway must be easy to design, using products with characteristics that meet real network needs. High integration levels reduce component count, increasing robustness in the challenging vehicle environment while also reducing the BoM cost.
