NXP System Basis Chip Leads Car Network Performance to a New High

NXP Semiconductors (NXP Semiconductors) today launched its second-generation automotive network CAN / LIN system basis chip (SBC)-UJA107x product series. UJA107x SBC optimizes performance, power consumption, and electronic control unit (ECU) costs, benefiting body control modules, in-vehicle temperature control, seat control, electric power steering (EPS), adaptive lighting, rain / light intensity sensors, A wide range of in-vehicle applications such as parking assist and transmission modules.

SBC adopts the industry-leading NXP CAN / LIN transceiver, and also has an in-vehicle microcontroller and an expandable voltage regulator for peripherals, so that this series of products can provide a high degree of integration, excellent performance and scalability. In addition, the UJA107x SBC series combines high-level ESD protection and outstanding EMC performance, fully satisfying the OEM's stringent reliability requirements. At the same time, the extremely low standby and quiescent current are conducive to saving fuel and reducing CO2 emissions.

Rob Bouwer, Global Product Marketing Manager, NXP Semiconductors, said: "Currently, the number of ECUs installed in new models has exceeded 50, which makes OEMs urgently need small, compact, cost-effective and long-term reliable solutions. The second generation of SBC allows us to further Strengthen our leading position in the CAN / LIN transceiver that has been popular for a long time, and at the same time further extend the successful experience of our first-generation fail-safe SBC. UJA107x series products meet the first-level supply with high stability and flexibility The key requirements of manufacturers, they will greatly help our customers and vehicle manufacturers in various global market segments to improve the comfort and safety of in-vehicle applications. "

NXP's SBC series provides the most comprehensive product portfolio, the entire series of products are pin compatible, and are all in a consistent compact "dark green" standard HTSSOP32 package. In order to adapt to different applications, all UJA107x SBCs are available with 5V or 3.3V Power Supply specifications, and can also choose whether to attach a watchdog program. This series of new SBC products include:

• UJA1078, HS-CAN plus dual LIN / J2602 SBC
• UJA1075, HS-CAN plus LIN / J2602 SBC
• UJA1076, HS-CAN SBC
• UJA1079, LIN / J2602 SBC

NXP SBC saves board space, improves quality and reliability, and at the same time significantly reduces the overall material cost, which greatly simplifies the design and layout of the ECU.

Technical information The main features of the NXP UJA107x SBC series include:
• High-speed CAN transceiver that complies with ISO11898-2 and ISO11898-5 standards • LIN transceiver that complies with LIN2.1, LIN2.0, and J2602 standards Press (V1)
• Very low standby mode current of 75µA (typical) (V1 is in operation)
• Sleep mode current is 55µA (typical)
• High-performance ESD protection on CAN / LIN and wake-up pins (± 6kV according to IEC61000-4-2 requirements)
• 2 wake-up ports with cyclic bias selection • Excellent EMC performance for stable, interference-free automotive applications • Limp Home function • Compact “dark green” standard HTSSOP32 package

NXP's expandable voltage regulator is unique, it supports 250mA output current, in addition to configuring an external PNP for heat dissipation, the designer can place it anywhere on the PCB.
