STA8089GADTR

RF Receivers Overview

The STA8089GADTR is an automotive-grade GNSS receiver IC from the Teseo III family, supporting GPS, Galileo, GLONASS, BeiDou, and QZSS constellations. It features 48 tracking channels and 2 fast acquisition channels with -162 dBm sensitivity. The device integrates an ARM946 MCU running up to 196 MHz, 256 Kbyte SRAM, and ST DRAW dead reckoning support. Operating voltages include 1.8 V main, 1.6–4.3 V backup, and 1.1–1.32 V digital. It operates within -40°C to +85°C in a 7x7 mm VFQFPN-56 package.

RF Receivers Feature Summary

• Supports multiple global navigation satellite systems including GPS, Galileo, GLONASS, BeiDou, and QZSS with dedicated tracking and acquisition channels.
• Integrates a high-performance ARM946 microcontroller unit for embedded processing and navigation data output.
• Includes ST DRAW (Dead Reckoning Automotive Way) functionality for enhanced positioning continuity.
• Features integrated RF front-end and low-noise amplifier within a single die architecture.

RF Receivers Applications

• Automotive telematics and navigation systems
• Fleet management and tracking solutions
• Advanced driver assistance systems (ADAS)
• In-vehicle infotainment navigation

RF Receivers Procurement Notes

Verify that the specific part number suffix matches the required automotive qualification and feature set. Confirm voltage regulator requirements align with system design constraints. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Cross-reference pin compatibility if replacing legacy components like the STA8088GA series.

RF Receivers Selection Notes

Select this component when multi-constellation support and dead reckoning capabilities are required for automotive applications. Consider the integrated MCU resources for firmware complexity. Evaluate power supply stability across the specified operating temperature range. Verify interface compatibility with host controllers for UART, I2C, CAN, and USB connections.

RF Receivers Part Context

The STA8089GADTR belongs to the Teseo III product family, designed for robust standalone positioning. It is AEC-Q100 qualified and pin-to-pin compatible with previous generations like the STA8088GA. The device combines RF reception with baseband processing in a compact surface-mount package suitable for space-constrained automotive PCB layouts.

RF Receivers Replacement Considerations

The STA8089GR is a pin-compatible alternative within the same family but lacks the ST DRAW dead reckoning feature found in the GAD variant. Ensure functional requirements match before substitution.
