Teseo-LIV3F Tiny GNSS module Datasheet - target specification standalone positioning receiver IC working simultaneously on multiple constellations (GPS/Galileo/Glonass/BeiDou/QZSS). The Teseo-LIV3F modules bring the proven accuracy and robustness of Teseo chips to the reach of everyone: the embedded firmware and the complete evaluation environment save development time, while the compactness and cost-effectiveness of this solution make it ideal for several applications, such as insurance, goods tracking, drones, tolling, anti-theft systems, people and pet location, vehicle tracking, emergency calls, fleet management, vehicle sharing, diagnostics and public transportation. Within its 9.7x10.1 mm tiny size, Teseo-LIV3F is Features offering superior accuracy thanks to the on board Simultaneous multiconstellation 26 MHz Temperature Compensated Crystal Oscillator (TCXO) and a reduced Time To First Fix -163 dBm tracking sensitivity (TTFF) relying to its dedicated 32 KHz Real Time 1.5 m CEP position accuracy Clock (RTC) oscillator. 16 Mbit embedded Flash for data logging and Thanks to the embedded 16 Mbit flash Teseo- FW upgrade LIV3F offers many extra features such as data 2.1 V to 4.3 V supply voltage range logging, 7 days autonomous assisted GNSS, FW reconfigurability as well as FW upgrades. Tiny LCC 18 pin package (9.7x10.1) Operating temperature (-40, 85C) Teseo-LIV3F provides also the Autonomous Assisted GNSS able to predict satellite data Free FW configuration based on previous observation of satellite. 17 W standby current and 75 mW tracking Teseo-LIV3F module, being a certified solution, power consumption optimizes the time to market of the final applications with a temperature operating range Description from -40C to 85C. The Teseo-LIV3F module is an easy to use Global Navigation Satellite System (GNSS) standalone module, embedding Teseo III single die Table 1.
