NXP introduces a range of RF chips for long-range smart car key functions

     NXP introduces its new Mantra RF portfolio, a line of high-performance transceivers and receivers for secure automotive theft prevention and vehicle management. The chip family provides long-distance, bidirectional RF links, enabling stable and reliable bidirectional communication between car keys and the car at distances of several hundred meters. Mantra's car keys allow users to easily check fuel levels, battery levels and the latest maintenance data from a distance. The owner can also check if the doors and Windows are locked, operate the door locks for long distances, start the vehicle and set the vehicle temperature.

     Jens Hinrichsen, senior vice president of NXP Semiconductors' Secure Automotive Security and Networks division. "Car keys are an important differentiating factor for various vehicle brands. NXP is committed to continuously raising the bar in vehicle gating functionality, performance and safety. The new Mantra RF solution sets a new industry standard for secure, two-way, long-distance communications."

     The Mantra family of products is designed for the mid-to-high end of the automotive door control market and provides ultra-high sensitivity and anti-noise performance, thereby increasing stability against radio interference and enabling signal reception to be uninterrupted. In addition, it contains an innovative concept: Mantra is the only chip family in the automotive market that offers a three-channel receiver capable of receiving up to three channels simultaneously. Multi-channel reception ensures that no signal is lost, resulting in ultra-high system stability with ultra-low power consumption. In addition, this new concept makes it possible to integrate different receiver devices, such as tire pressure monitoring, vehicle diagnostics and vehicle management devices, into the vehicle gate module, thereby reducing the total system cost. Mantra's product family offers strong security and authentication features to prevent unauthorized access.
