STA8089FGB

RF Receivers Overview

The STA8089FGB is a standalone GNSS receiver IC from the Teseo III family, supporting GPS, Galileo, GLONASS, BeiDou, and QZSS. 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 kB SRAM, and in-package SQI Flash Memory (16 Mbits). Key interfaces include 3 UARTs, I2C, SSP, USB 2.0, and 2 CAN channels. Operating voltages are VDD 1.0V-1.32V, VINL 1.8V±5%, and VINB 1.6V-4.3V. It operates within -40°C to +85°C in a 56-VFQFPN package.

RF Receivers Procurement Notes

Verify that the specific suffix 'FGB' corresponds to the standard Teseo III firmware capabilities without ST-DRAW dead reckoning support, which is reserved for the FBD variant. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure voltage supply rails match the specified ranges for VDD, VINL, and VINB during design validation.

RF Receivers Selection Notes

Select this component when multi-constellation support and integrated processing power are required. It offers backward compatibility with the STA8088FG for migration purposes. Consider the FBD variant if dead reckoning functionality is needed. Verify interface requirements against available UART, SPI, and CAN channels.

RF Receivers Part Context

Part of the Teseo III family, designed for robust standalone positioning. It eliminates the need for external memories by embedding flash and SRAM. The single-die architecture reduces board space and complexity compared to discrete solutions.

RF Receivers Replacement Considerations

The STA8088FG is pin-to-pin compatible for application migration. Other Teseo III variants may offer different firmware features or interface configurations.
