NXP CAN/LIN system basis chip family addresses EMC and integration

September 01, 2010 | Christoph Hammerschmidt | 222901049
NXP CAN/LIN system basis chip family addresses EMC and integration NXP Semiconductors has launched a new generation of CAN/LIN System Basis Chips (SBCs) for in-vehicle networks. Offering enhanced EMC (Electromagnetic Compatibility) performance, the UJA107xA chips meet the stringent requirements of global car OEMs such as Audi, BMW, Daimler, Ford, Porsche, Renault, Toyota and Volkswagen.

Key features of the new SBC product family include outstanding ESD and EMC performance, and very low quiescent currents, the vendor promises. In addition, integrated fail-safe functions such as Watchdog and Limp Home enhance automotive system safety. NXP UJA107xA SBCs optimize the performance, power consumption and cost of electronic control units (ECUs) for a broad range of automotive applications, such as body control modules, climate control, seat control, electric power steering (EPS), adaptive lighting, rain/light sensors, parking assistance and transmission.

According to international product marketing manager Rob Bouwer, the design of the new System Basis Chips reflects several important design trends in the automotive industry. These include higher levels of integration and the requirement to increase EMC robustness, power efficiency and safety.

Featuring NXP's CAN and LIN transceivers, NXP SBCs offer a high level of integration, performance and scalability for designers. The UJA107xA SBC family reduces board space area by more than 50 percent by integrating more than 10 active components into one single System Basis Chip. The UJA107xA core SBC replaces a number of basic discrete components commonly found in ECUs with a high-speed CAN as well as LIN interfaces. In addition to the advantages gained from integrating ECU functions in a single package, the core SBC offers a combination of system-specific features such as advanced low-power concept, safe and controlled system start-up behavior, and detailed status reporting on system and sub-system levels, NXP says.

The UJA107xA is designed to be used in combination with a microcontroller incorporating a CAN controller, ensuring that the MCU always starts up in a controlled manner. The UJA107xA supports the networking applications used to control power and sensor peripherals by using high-speed CAN as the main network interface and the LIN interface as a local sub-bus.

The UJA107xA SBCs are available for ordering immediately and additional information is available here. Test reports from C&S group GmbH, IBEE Zwickau, and UL, as well as the VeLIO report, are available upon request.
