Trimension NCJ29D6 is a fully integrated single chip impulse radio Ultra-Wideband low-energy transceiver IC compliant to IEEE 802.15.4 HRP UWB PHY and IEEE 802.15.4z BPRF/HPRF UWB PHY. It is designed for secure ranging applications and radar applications in an automotive environment. Besides supporting Digital Key functionality for secure truly hands-free car access, the NCJ29D6 enhances this feature with radar capabilities. This enables applications such as Child Presence Detection (CPD) and kick-sensing for easy trunk access. With combined ranging and radar support, the NCJ29D6 maximizes system value and reduces system cost.
