FAQ

What is the operating frequency range of the NCJ29D5CHN/00200Y?

The NCJ29D5CHN/00200Y operates in the high-band UWB spectrum from 6.0 GHz to 8.5 GHz. This range is specified in NXP document NCJ29D5UWBFSA4 REV 0 and enables superior ranging resolution and multipath immunity compared to lower UWB bands. The IC supports IEEE 802.15.4z Channel 5 and Channel 9 operation within this band.

Does the NCJ29D5CHN/00200Y support secure ranging against relay attacks?

Yes, the NCJ29D5CHN/00200Y implements hardware-enforced time-of-flight distance bounding using cryptographic challenge-response protocols. Its integrated Arm® Cortex® core and dedicated cryptographic engine execute FiRa-compliant secure ranging sequences with sub-100 ns timing precision, making relay attacks physically infeasible.

Is the NCJ29D5CHN/00200Y qualified for automotive use?

Yes, the NCJ29D5CHN/00200Y is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient), as documented in NXP's official qualification report. It is designed for integration into automotive body control modules, door handle ECUs, and infotainment head units requiring robust operation in vehicle environments.

What power supply voltages does the NCJ29D5CHN/00200Y require?

The NCJ29D5CHN/00200Y requires two independent supply rails: VDDA_1P8 (1.8 V ±10%) for analog/RF circuits and VDDD_1P2 (1.2 V ±10%) for the digital core and Arm® Cortex® subsystem. Both rails must be locally decoupled per NXP layout guidelines in NCJ29D5UWBFSA4 REV 0.

Does the NCJ29D5CHN/00200Y include an integrated microcontroller?

Yes, the NCJ29D5CHN/00200Y integrates an Arm® Cortex®-based embedded processor that executes UWB MAC/PHY layers, secure ranging protocols, and cryptographic operations without requiring an external MCU. This reduces system latency and simplifies design for automotive access and localization applications.
