NXP Unveils First Monolithic UWB Chip NCJ29D6, Integrating MCU and Short-Range Radar for Advanced Car Access Security

NXP introduces Trimension NCJ29D6: Next-Gen Monolithic UWB Chip Redefining Car Access Security. Integrating MCU and Short-Range Radar, the Single-Chip Solution Offers Precise Real-Time localization, Child Presence Detection (CPD), Intrusion Alert, Living Object Detection (LOD), Enhanced Performance, Lower Costs, and Superior Security for Diverse Automotive Applications.

Trimension NCJ29D6 empowers OEMs to convert a single UWB-based car access system into a highly adaptable, multi-functional platform, accommodating various use cases with a unified hardware solution. This approach enables OEMs to eliminate redundant systems, thereby reducing costs, saving space, and minimizing weight.

This addition not only aligns with regulatory requirements like the U.S. Hot Cars Act and the European NCAP roadmap but also showcases the chip’s capability to address safety concerns beyond conventional access control.

The Trimension NCJ29D6 UWB chip, integrated into the car’s access system, can go beyond securing the vehicle. Through the same hardware, it enables child presence detection by sensing the UWB signals within the car’s interior. If the system detects the presence of a child after the parent has left the vehicle, it could trigger an alert or take preventive actions to ensure the child’s safety.

The NCJ29D6B is pin-to-pin compatible with the NCJ29D6A and expands location features by incorporating short-range UWB radar, making it the first automotive device to combine these capabilities in a single chip with an integrated MCU.

This integration allows the chip to perceive its surroundings, enabling OEMs to convert a UWB-based system into a versatile platform for various applications. Beyond secure car access, automotive manufacturers can leverage the NCJ29D6A for in-cabin sensing, including child presence detection and seat belt reminders, as well as features like a kick sensor for automatic trunk opening and diverse smart gesture recognition functionalities. This integration maximizes the utility of UWB capabilities in automotive settings.
