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]

The company U-Blox have announced the EVA-7M, a standalone GNSS positioning module claimed to be the smallest complete solution on the market. It supports US GPS, Russian GLONASS, Japanese QZSS, plus all SBAS augmentation systems. The module contains all the necessary components, including crystals and passives, it’s only necessary to add an antenna to give global positioning capability. The chip uses the company’s advanced GNSS u-blox 7 technology and achieves -160 dBm sensitivity when tracking GPS satellites (-158 dBm with GLONASS satellites). An integrated high-efficiency converter keeps power requirements down to 16.5 mA at 3 V.

The 7 x 7 x 1.1 mm LGA module eases implementation in end-products because both RF and digital domains are integrated and kept separate in the chip. The LGA pads are configured in single rows, unlike other GNSS receivers on the market. The EVA is a standalone receiver, providing positional information without the need for host integration or extra RF components. [via]

Company Quectel launches on the market a miniature quad-band GSM/GPRS module featuring reach functionality and extremely low power consumption.

M80 has all features, which we usually require from a modern GSM/GPRS module: GSM/GPRS performance for data, voice, sms and multimedia, powerful Internet service protocols, multiple Sockets & IP addresses. M80 provides a high performance at a very low power consumption and an extended specified temperature range from -35 to +80 °C (with restrictions -45 to +85°C). With the extremely low power consumption and only 2,6mm high LGA package it is suitable even for miniature mobile devices.

M80 is a complete powerful hardware platform for all M2M (machine to machine) applications. Detailed information provide documents M80 Hardware Design, M80 ATC and the M80 datasheet. Also available is the evaluation kit.
