New CAN/LIN ICs for in-vehicle networks from NXP

NXP Semiconductors has released the UJA107xA family, its CAN/LIN System Basis Chips (SBCs) for in-vehicle networking. These ICs offer enhanced EMC (Electromagnetic Compatibility) performance and is suitable for 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.

The UJA107xA SBC family provides good ESD and EMC performance and low quiescent currents. This device has fail safe functions such as Watchdog and Limp Home enhance automotive system safety. The 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."

These chips use NXP's CAN and LIN transceivers. NXP says that the UJA107xA SBC family reduces board space area by more than 50% 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. These SBCs 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 new SBCs from NXP include:
UJA1078A HS-CAN and dual LIN SBC
UJA1075A HS-CAN and LIN SBC
UJA1076A HS-CAN SBC
UJA1079A LIN SBC
