NXP Semiconductors launched its first assisted-GPS (A-GPS) chip, the GNS7560, targeting mobile phones and standalone personal navigation devices (PNDs) with the product’s package size of less than nine square millimeters.

The February 4 announcement follows shortly after the January 23 closing of NXP’s acquisition of GPS technology provider GloNav, Inc., by the Einhoven, The Netherlands–based company. The NXP GNS7560 is implemented on a 90-nanometer architecture and features a CMOS RF front end plus correlator engine with power management modes that reduce power consumption to less than 13mW for one-second updates, according to the company.

Reportedly, the OEM receiver is designed to automatically alter its sensitivity and tracking based on signal strength, multipath, and velocity. Host software for the product is structured to facilitate OS integration with Microsoft Windows CE, Windows Mobile, and Linux standard drivers, as well as a variety of real-time kernels in support of “smartphone” designs.

The single-chip GNS7560 is integrated with NXP’s Nexperia UMTS/EDGE Cellular System Solution 7210, which supports multimedia applications and connectivity options for 2G and 3G mobile handsets. The Nexperia Cellular System Solution will be shown in NXP’s booth (Hall 8, B110) at Mobile World Congress in Barcelona, Spain from February 11-14.

NXP says the standalone GNS7560 A-GPS chip is sampling now.
