NXP’s Advanced Trimension UWB Portfolio Hits the Road with Audi

NXP Semiconductors N.V. announced that its Trimension^® NCJ29Dx family, part of one of the industry’s broadest UWB portfolios, is the technology foundation for Audi’s advanced new UWB platform, delivering the precise and secure real-time localization required by leading premium car manufacturers to enable hands-free secure car access via smart mobile device and other UWB-based features. Cars featuring NXP’s Trimension UWB devices, including the Audi Q6 e-tron, will hit the road in 2024.

Smart, secure car access leverages the fine-ranging capabilities of NXP’s extensive Trimension UWB portfolio to precisely identify the location of the driver in relation to the car, allowing the doors to be unlocked only when the driver is in close proximity to the car. Drivers can unlock and start their car hands-free using a digital key on a UWB-enabled mobile phone or wearable, which can remain in the driver’s pocket or bag.

The Trimension NCJ29Dx family is part of NXP’s portfolio of secure car access system solutions, which includes the NCF3340 NFC controller and the KW37 Bluetooth 5.0 Long-Range MCU. These devices are also in use by Audi as part of its new platform. It also enables UWB-based fine-ranging capabilities and is compliant to IEEE 802.15.4, CCC and FiRa standardization. It delivers high localization resolution and power optimization for battery-powered devices such as key fobs, while also minimizing BOM costs. Additionally, it offers maximum levels of protection against car theft through relay attacks and includes on-chip support for a wide range of cryptographic operations.

The Trimension NCJ29Dx family is part of one of the industry’s broadest UWB portfolios, which features devices suitable for both automotive and mobile, IoT or industrial applications. This includes devices like the Trimension NCJ29D6, which integrates UWB fine ranging with UWB radar capabilities to allow OEMs to address multiple use cases with a single system, including smart, secure car access, child presence detection, intrusion alert, kick sensing and more.
