World Peace Group launched a digital car key solution based on NXP products

The advent of the automobile era has brought wireless access technology into the public’s field of vision. Although the traditional Electronic car key using PKE/RKE technology brings great convenience to the use of the car, it also has hidden dangers such as being vulnerable to relay attacks and inaccurate Bluetooth positioning of mobile phones. Based on the NXP NCJ29D5, the digital car key solution launched by Dalian Da Shiping embeds UWB centimeter-level positioning technology into it, which not only has higher positioning accuracy, but also supports mobile phone operation. Keyless entry, one-key start and other functions.

On September 1, 2021, Dalian General Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its subsidiary World Peace has launched a digital car key solution based on NXP (NXP) NCJ29D5.

This solution is mainly divided into 5 parts, namely: key terminal, body anchor point, in-vehicle anchor point, base station Bluetooth and BCM, among which, the key terminal is composed of BLE KW38 + UWB NCJ29D5. The NCJ29D5 is the first in a new generation of ultra-wideband (UWB) ICs from NXP designed to meet the connectivity and functional safety needs of the global automotive industry. The UWB IC enables the car to accurately identify the user’s location, and the positioning error is accurate to the centimeter level. This provides the same convenience as a first-class key fob for smartphone-based car access technology. Users can open and start the car with their phone in their pocket or bag, and enjoy secure remote parking via their smartphone. In addition, the new UWB IC also minimizes the risk of car theft through relay attacks.

In terms of performance, the NCJ29D5 is compliant with the IEEE 802.15.4 HRP UWB PHY standard, capable of operating in high frequency bands from 6.5 GHz to 8.0 GHz (AES-128 and AES-256), and has excellent immunity to interference. In design, the device uses ARM® Cortex-M33 32-bit processor, based on ARM® AHB-Lite bus matrix and dual-master NS-DMA design for fast data transfer. Not only that, NCJ29D5 also has ultra-low power consumption, Hard Power Down State can reach nA level, and built-in configurable current limiter, which can be used in button battery-powered applications.

Core technical advantages:

• UWB is a carrier-free signal, using nanosecond-level narrow pulses to transmit data, with a bandwidth of 500MHz;
• Accurate positioning, centimeter-level positioning can be achieved;
• Low system complexity and low transmit signal power spectral density;
• Frequency range: 3.1GHz~10.6GHz, can coexist with Wi-Fi/Bluetooth and other signals;
• Insensitive to channel fading and strong multipath resolution.

Program Specifications:

• Compliant with IEEE 802.15.4Z HRP UWB PHY standard;
• Support center frequency from 6.5 GHz to 8.0 GHz (AES-128 and AES-256);
• Body multi-anchor point positioning scheme (BLE+UWB);
• It can prevent relay attacks and encrypt the positioning data.
