Next-gen NXP SBCs address stringent EMC requirements of global car OEMs

EINDHOVEN, THE NETHERLANDS: NXP Semiconductors N.V. has released the UJA107xA family, its next generation of CAN/LIN System Basis Chips (SBCs) for in-vehicle networks.

Offering enhanced EMC (Electromagnetic Compatibility) performance, the chips meet the stringent requirements of global car OEMs such as Audi, BMW, Daimler, Ford, Porsche, Renault, Toyota and Volkswagen.

“Compliance with stringent automotive industry requirements is the result of intense collaboration between NXP and German OEMs in the design and test phase of the UJA107xA family,” said Carsten Schanze, responsible for Networking Hardware at Volkswagen.

Key features of the UJA107xA SBC family include outstanding ESD and EMC performance, and very low quiescent currents, which help to reduce fuel consumption and CO2 emissions. 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.

“As electronic content in cars continues to increase EMC robustness, power efficiency and safety have become critical requirements for in-vehicle networks,” said Rob Bouwer, international product marketing manager, NXP Semiconductors.

“We see a clear trend in the market towards higher levels of integration. This trend is fuelled by the need for lower total system cost, as well as more compact, more reliable solutions. The next generation of UJA107xA SBCs demonstrates NXP’s expertise in in-vehicle networking, as well as the integration of high-voltage analog with digital functionality by using state-of-the-art Silicon-on-Insulator technology.”

Featuring NXP’s industry-leading CAN and LIN transceivers, NXP SBCs offer a very 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 the 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 an intelligent 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.

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 latest generation of SBCs from NXP includes:

* UJA1078A HS-CAN and dual LIN SBC.
* UJA1075A HS-CAN and LIN SBC.
* UJA1076A HS-CAN SBC.
* UJA1079A LIN SBC.

The UJA107xA SBCs are available for ordering immediately.
