New Mantra To Access Car Information Over Hundred Meters


The new Mantra to identify your car and access vital information over a distance of several hundred meters is here. The newly launched Mantra RF chip by NXP is a smartcar key that acts as a secure bi- directional communication device.

According to the press release, Mantra RF solution is designed for the mid-to-high-end car market. Adding further, “The Mantra family is currently the only chip family on the automotive market that offers a triple-receiver for simultaneous reception of up to three channels at very low power consumption. Furthermore, this new concept enables the integration of different receiver units, such as tire-pressure monitoring, car diagnostics and car management, into the car-access module to reduce the overall system costs. The Mantra family provides strong security and authentication features to prevent unauthorised access.”

Jens Hinrichsen, senior vice president secure car access & networking, NXP Semiconductors, said, ‘The car key is an important differentiator for every car brand.
