Telit and SiTime have teamed up to produce what is claimed to be, at 4.7 × 4.7 mm LGA (Land Grid Array) package, the world’s smallest and lowest power GPS receiver chip. The SiRFstarIV-based Jupiter SE880 receiver module allows extended hibernation periods drawing just 15 µA while maintaining a less than one second Snap Start.
The receiver combines Telit’s Jupiter SE880 miniature GPS receiver with SiTime’s MEMS SiT15xx low power oscillators. Its tiny footprint and low power consumption means that future mobile tracking devices and navigation aids can be made smaller and will last longer between charges.
The 750 nA core current and power saving features of the 32 kHz SiT15xx family contribute to the chips low power consumption compared to systems using traditional crystal clocks. [via]
