Overview
The STA8090FGBD, although not directly detailed, is part of the Teseo family of GNSS receiver ICs from STMicroelectronics. Similar to the STA8089FG, it is likely a highly integrated single-chip standalone GNSS receiver designed for positioning system applications. These devices embed the STMicroelectronics GNSS positioning engine capable of receiving signals from multiple satellite navigation systems, including GPS, Galileo, GLONASS, BeiDou, and QZSS.
