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 currently being used by Audi as part of its new automotive platform.
The Trimension NCJ29Dx family enables UWB-based fine-ranging capabilities and is compliant with IEEE 802.15.4, CCC and FiRa standardisation. It delivers high localisation resolution and power optimisation for battery-powered devices such as key fobs, while also minimising 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 NCJ29Dx family provides IEEE 802.15.4 forward and backward compatibility. A dual antenna interface is provided for antenna diversity, maximum ratio combining, and angle-of-arrival estimation. Full duplex UWB radar is integrated using NXP’s radar sensitivity boost technology. Besides the integration of the Arm Cortex core MCU, the NCJ29Dx also includes a CAN FD controller for easy integration into a vehicle control system.
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.
