Fail-Safe CAN LIN System Basis Chips for Automotive System - NXP

NXP launched the fail-safe CAN-LIN system basis chips (SBCs) with integrated diagnostics for smarter Electronic Control Units (ECUs), raising the industry standard for in-vehicle networking. NXP has launched two new fail-safe system basis chips as part of this family: the UJA1061 fault-tolerant CAN/LIN and the UJA1065 high-speed CAN/LIN system basis chip.

The fail-safe SBCs are capable to support all In-Vehicle Networking (IVN) applications that control various power and sensor peripherals by using fault-tolerant CAN or High-speed CAN as the main network interface and LIN as a local sub-bus.

Rob Bouwer, NXP, said:

NXP's new fail-safe system basis chips are based on insights from carmakers, who need reliable networks for various in-car communications and also do not allow for battery drainage or network deadlock should any ECU fail…

The diagnostic capabilities of the NXP system basis chips further enhance consumer experience by detecting and logging problems that get resolved at the service shop, before the driver notices…

The fail-safe SBCs  offer car manufacturers an intelligent combination of system-specific functions, including:

• Advanced fail-safe system behavior that prevents any conceivable deadlock
• Detailed status reporting on system and sub-system levels
• Safe and controlled system start-up behavior and smart operating and power management modes
• The ability to create partial CAN networks

NXP's fail-safe system basis chips offer versatility of integration with various car manufacturers for a variety of applications, including body control modules, rain and light sensors, seat and door modules, as well as heating, ventilation and air conditioning (HVAC) systems. The system basis chips help improve network reliability by keeping ECU faults locally, preventing adverse effects on the entire network. These system basis chips also support intelligent, restrictive activation of only those ECUs required for communications to ensure low levels of power consumption.
