NXP Semiconductor has released CAN/LIN System Basis Chips (SBCs) coded UJA107x for automotive in-vehicle communication networks. The UJA107x SBCs are designed for electronic control units (ECUs) used in automotive applications such as body control modules, climate control, seat control, electric power steering (EPS), adaptive lighting, rain/light sensors, parking assistance and transmission.

These chips integrate CAN and LIN transceivers, a scalable voltage regulator for the on-board microcontroller and peripherals. UJA107x SBC family features better ESD protection and EMC performance making them more reliable.

"New cars today have over 50 ECUs on board, making it imperative for OEMs to select solutions that are compact, cost-efficient and reliable over the long term," said Rob Bouwer, international product marketing manager, NXP Semiconductors. "With our second-generation SBCs, we've been able to build on the proven track record of our popular CAN and LIN transceivers, and the success of our first-generation Fail-Safe SBCs. The UJA107x family addresses the key requirements of major Tier 1 suppliers with a robust, highly flexible offering that will go a long way in helping our customers and car makers bring advanced safety and comfort features to vehicles in all segments of the worldwide automotive market."

NXP offers the wide range of variants in a single family of SBCs, which are pin-to-pin compatible and share the same compact Dark Green HTSSOP32 package. All UJA107x SBCs can be offered with a 5V or 3.3V power supply, and with or without a watchdog, for optimal fit. The new family of SBCs include:

UJA1078, a HS-CAN and dual LIN/J2602 SBC
UJA1075, a HS-CAN and LIN/J2602 SBC
UJA1076, a HS-CAN SBC
UJA1079, a LIN/J2602 SBC

Key features of the versatile NXP UJA107x SBC family include:

ISO11898-2 and ISO11898-5 compliant HS-CAN transceiver
LIN2.1, LIN2.0 and J2602 compliant LIN transceiver
A scalable voltage regulator (V1) for microcontroller (3V3 or 5V) and peripherals
Very low Standby mode current of 75µA typ. with V1 active
Sleep mode current of 55-µA typ
High ESD protection (± 6kV according to IEC61000-4-2) on CAN/LIN and wake pins
2 wake-up ports with cyclic biasing option
Excellent EMC performance for robust, interference-free operation in the car
Limp Home
Compact Dark Green HTSSOP32 package

The scalable voltage regulator supports a 250mA output current, and an external PNP for heat distribution, which designers can place anywhere on the PCB.

Availability: The UJA107x SBCs are available for ordering immediately
