Overview
The STA8089FGA is a highly integrated single-chip standalone GNSS (Global Navigation Satellite System) receiver developed by STMicroelectronics. It belongs to the Teseo III family of products and is designed to support multiple satellite navigation systems, including GPS, Galileo, GLONASS, BeiDou, and QZSS. This device is AEC-Q100 qualified, ensuring it meets stringent automotive standards, and is backward compatible with the STA8088FG, facilitating easy migration for customers. The STA8089FGA comes with a complete GNSS firmware that handles all GNSS operations without the need for external memories. Additionally, the STA8089FGAD variant supports STMicroelectronics' dead reckoning firmware, TESEO-DRAW.
