STA8090GATR Visão geral
A GNSS receiver is a specialized radio receiver that processes signals from satellite navigation systems to determine precise geographic position, velocity, and time. It is a critical component in the broader positioning and navigation system hierarchy, which includes antennas, RF front-ends, baseband processors, and application processors. The STA8090GATR combines these functions into a single chip, reducing system complexity and power consumption.
Key features of the STA8090GATR include support for concurrent reception of GPS, Galileo, GLONASS, and BeiDou signals, a high-sensitivity RF front-end with -162 dBm tracking sensitivity, and an integrated ARM-based baseband processor. It also features a low-power mode with typical current consumption of 25 mA during continuous tracking, and a standby current of 10 uA. The device operates from a 1.8V supply and includes an integrated LDO for internal voltage regulation.
The STA8090GATR utilizes advanced CMOS technology and a multi-core architecture to handle complex signal processing algorithms, including multipath mitigation and interference rejection. Its high sensitivity and fast time-to-first-fix (TTFF) make it suitable for demanding environments such as urban canyons and dense foliage. The device also supports assisted GPS (A-GPS) and ephemeris prediction for faster fixes.
Typical applications include automotive navigation systems, fleet management, telematics, and portable navigation devices. The STA8090GATR is also used in IoT devices requiring location tracking, such as asset trackers and wearables. Its low power consumption and small footprint make it an excellent choice for battery-powered applications.
When designing with the STA8090GATR, ensure proper antenna matching and grounding for optimal RF performance. The device requires a clean 1.8V supply and careful PCB layout to minimize noise and interference. Refer to the STMicroelectronics application notes for detailed design guidelines.

Notas de projeto
For optimal RF performance, place the STA8090GATR close to the antenna and ensure a 50-ohm impedance-controlled trace for the RF input. Use a ground plane beneath the RF section and add decoupling capacitors (100nF and 10uF) near the VCC and VCC_RF pins. Follow STMicroelectronics' layout guidelines for the VFQFPN-56 package.
The STA8090GATR requires a clean 1.8V supply. Use a low-noise LDO to power the device and avoid sharing the supply with digital circuits that may introduce noise. Add a ferrite bead in series with the supply to filter high-frequency noise. The integrated LDO helps regulate internal voltages, but external decoupling is still necessary.
Ensure the antenna is properly matched and has a clear view of the sky for optimal signal reception. Avoid placing the device near sources of electromagnetic interference, such as switching regulators or high-speed digital lines. Also, verify that the UART/SPI/I2C lines are not routed near the RF input to prevent coupling.
