Atmel and u-blox have released the ATR0625, a baseband IC with SuperSense GPS weak-signal tracking software included in its ROM. ATR0625 is based on the companies' Antaris 4 platform, which is a low-power, 16-channel GPS technology developed for automotive, handheld and mobile applications such as OEM car navigation, mobile phones, PDAs, personal navigation devices, and recreational products. With the integration of the SuperSense software on masked ROM, an external Flash memory becomes unnecessary, decreasing power consumption and size. SuperSense uses a combination of coherent and incoherent tracking combined with variable integration times for the individual satellites. The ATR0625 is packaged in QFN56 package and is pin-compatible with the ATR0622 Antaris 4 baseband IC with standard ROM software. This makes it easy for customers to enable their existing products with weak-signal tracking technology. The chip operates at 62 mW, but also has power saving modes. The ATR0625 works together with the ATR0601, a highly integrated, low-power GPS radio in a 4 x 4 mm QFN package.
