Overview
Overview
STA8090FG is a highly integrated single-chip standalone GNSS receiver designed for
positioning system applications.
STA8090FG embeds the new ST GNSS positioning engine capable of receiving signals
from multiple satellite navigation systems, including the US GPS, European Galileo,
Russia's Glonass, Chinese BeiDou and Japan's QZSS.
The STA8090FG ability of tracking simultaneously the signals from multiple satellites
regardless of their constellation, make this chip capable of delivering exceptional accuracy
in urban canyons and in the environments where buildings and other obstructions make
satellite visibility challenging.
STA8090FG embeds innovative power management with switching regulator for power
consumption optimization.
The extended voltage supply range from 1.6 V to 4.3 V, the 1.8 V and 3.3 V I/O compliance
support make the STA8090FG the suitable solution for different user applications.
The STA8090FG combines a high performance ARM946 microprocessor with I/O
capabilities and enhanced peripherals. It supports USB2.0 standard at full speed (12 Mbps)
with on-chip PHY.
The chip embeds backup logic with real time clock.
The device is offered with a complete firmware performing all positioning operations
including acquisition, tracking, navigation and data output with no need of external
memories.
The STA8090FG, using STMicroelectronics CMOSRF Technology, is housed in a
TFBGA99 (5 x 6 x 1.2 mm) package with stacked 16 Mbit Flash memory.
