STA8089GR

RF Receivers Overview

The STA8089GR is a single-die standalone GNSS positioning receiver IC from STMicroelectronics, supporting GPS, GLONASS, BeiDou, and QZSS constellations. It features 48 tracking channels and 2 acquisition channels with -163 dBm sensitivity. The device integrates an ARM946 MCU running at 196 MHz, 256 KB SRAM, and an RTC. Supply voltages include VINL (1.8 V), VINB (1.6–4.3 V), VDD (1.1–1.32 V), VCC (1.2 V ±10%), and VddIO (1.8/3.3 V). It operates within -40°C to +85°C in a 7x7 mm VFQFPN-56 package.

RF Receivers Feature Summary

• Integrates a high-performance ARM946 MCU for embedded firmware execution and navigation data processing.
• Supports multi-constellation reception including GPS, GLONASS, BeiDou, and QZSS with dedicated RF front-end.
• Provides comprehensive GNSS operations such as signal tracking, acquisition, and data output on a single die.

RF Receivers Applications

• Automotive telematics and navigation systems
• Fleet management and asset tracking devices
• Consumer electronics requiring precise location services

RF Receivers Procurement Notes

Verify the specific suffix against the official datasheet to confirm pinout compatibility and voltage levels. Ensure the procurement source provides valid AEC-Q100 certification documentation if automotive qualification is required. Confirm moisture sensitivity handling procedures are followed during storage and assembly to prevent package damage.

RF Receivers Selection Notes

Select this component when a fully integrated solution combining RF reception and baseband processing is required. It is suitable for designs needing pin compatibility with the STA8088G family. Consider the integrated ARM946 core for applications requiring local data processing without external microcontrollers.

RF Receivers Part Context

The STA8089GR belongs to the Teseo III product series of GNSS receivers. It represents a generation of single-chip solutions designed to reduce board space by integrating both the radio frequency frontend and the digital baseband processor into one package.

RF Receivers Replacement Considerations

The STA8089FGA is a compatible alternative within the same family offering similar multi-constellation support and interface options.
