Atmel Corp. and u-blox AG announced the availability of their latest weak-signal tracking GPS technology in an ultra-small form factor. The new single-chip ATR0635 measures just 7-by-10mm, and integrates a complete ANTARIS 4 GPS receiver including ROM-based SuperSense software in a 96-pin BGA package.

According to the press release, the small size and the low power consumption make the ROM-based ATR0635 suited for handheld and mobile applications such as mobile phones, PDAs, smartphones, after-market navigational products, and recreational consumer products. Other products such as GPS 'plug-in' accessories for PCs, small GPS mice, Bluetooth GPS devices, and other accessories equipped with GPS functionality will also enjoy the single chip's advantages in terms of small size, reduced power needs, and built-in features such as the ANTARIS 4 USB port.

The ATR0635 operates on 62mW, but its power saving modes, together with built-in power management capabilities, can bring power down to as low as 5 microamps, enabling power critical applications such as mobile devices to operate longer without having to compromise functionality. Additionally, its high tracking sensitivity of -158dBm allows for weak-signal tracking in urban canyons and even indoors.

ATR0635 also brings benefits such as simplified chipset integration which accelerates design projects for ANTARIS 4-based products, Atmel said. Lower PCB costs are achieved due to a 45 percent reduction in footprint and a simplified board layout, and by reducing costs in purchasing, stocking and mounting due to the low number of components. In addition, ATR0635 supports serial EEPROM memory and its on-chip USB connectivity eliminates the need for a serial-to-USB converter.

"SuperSense indoor GPS functionality means it can be used inside buildings, cars and in other difficult signal conditions without tracking interruptions, making the ATR0635 ideal for personal navigation devices, for instance," commented Georg zur Bonsen, Product Manager at u-blox.

ATR0635 samples in 7-by-mm 96-pin BGA packages are available now. The companies offer a complete evaluation kit including ultra-small footprint example design which helps shorten development cycle times.
