The ZN2014 is a fully integrated single chip Impulse Radio ultra-wideband (IR-UWB) SoC with low-power low-cost 1T3R transceiver compliant to IEEE802.15.4z. With BPRF & HPRF transmission, it can be used in Single-Sided (SS) and Double-Sided (DS) Two-Way Ranging (TWR), Time Differential of Arrival (TDoA), and Phase Differential of Arrival (PDoA) systems to locate assets to a ranging accuracy of +/-5cm and angle accuracy of +/-3°.
It also integrates secure module for data encryption and generation of the Scrambled Timing Sequence (STS) needed for IEEE802.15.4z enhanced secure ranging, which can effectively prevent the relay attacks for Passive-Entry-Passive-Start (PEPS) systems. Further, the key derivation for STS can be directly generated on-chip, fully compatible with the standard requirement of Car Connectivity Consortium (CCC3.0).
The ZN2014 also supports data transfer at different rates of 850Kbps, 6.8Mbps, 27.2Mbps and up to 54.4Mbps, which can support wireless audio and video transmission with much less latency compared with BLE, Wi-Fi, 5.8G and other wireless techniques.
