NXP Trimension NCJ29D6 UWB Deployed in BMW Group 2026 Vehicles

NXP Semiconductors N.V. (NXP) has announced that its Trimension NCJ29D6 Ultra-Wideband (UWB) family will be introduced across the BMW Group fleet, beginning with selected 2026 vehicle programs. The Trimension NCJ29D6 integrates secure fine-ranging and robust short-range radar capabilities into a single chip, allowing automakers to support multiple vehicle functions using one UWB platform while improving convenience, security, and occupant safety.

Single-Chip UWB Platform Expands Vehicle Capabilities

The Trimension NCJ29D6 combines secure distance measurement with reliable short-range radar technology in one semiconductor solution. This integrated approach enables original equipment manufacturers to implement several features through a single UWB system, including precise presence detection and seamless hands-free vehicle access. By consolidating these capabilities into one chip, the platform helps simplify system design while supporting advanced connected vehicle functions.

Supporting BMW Digital Key Plus

The solution also powers BMW's UWB-based Digital Key Plus, allowing compatible smartphones and smart watches to replace conventional key fobs. This enables drivers to unlock and access their vehicles without removing their devices while maintaining secure authentication through Ultra-Wideband technology. The deployment represents another step in expanding digital vehicle access across future BMW models.

Presence Detection Designed for Future Safety Requirements

The integrated presence detection function is designed to identify the possible presence of people or animals left inside parked vehicles and issue warning messages to vehicle users when necessary. The technology has been developed with potential future regulatory requirements and NCAP protocols in Europe and China in mind, supporting evolving vehicle safety expectations while leveraging the same UWB platform used for digital access features.
