STA8089FGAD

RF Receivers Overview

The STA8089FGAD is a fully integrated GNSS receiver from the Teseo III family, supporting GPS, Galileo, GLONASS, BeiDou, and QZSS. It features embedded RF circuitry and in-package flash memory within a 56-VFQFPN (7x7) surface-mount package. The device operates on a supply voltage of 1.08V to 1.32V and supports data rates up to 12Mbps. Key performance metrics include a sensitivity of -162dBm and operation across frequencies of 1.561GHz, 1.575GHz, and 1.601GHz. It includes 256kB SRAM and 512kB ROM, with I2C, SPI, UART, and USB interfaces.

RF Receivers Procurement Notes

Verify the specific ordering suffix to confirm package type and reel/tray configuration, as variations exist within the Teseo III family. Ensure compatibility with AEC-Q100 requirements if deploying in automotive environments. Cross-reference the datasheet version to confirm interface protocols and firmware capabilities. Confirm availability status, as some variants may have limited distribution or longer lead times due to manufacturing changes.

RF Receivers Selection Notes

Select this component when a single-chip solution for multi-constellation GNSS is required without external RF components. The embedded flash allows for flexible firmware updates and protocol handling. Consider the 56-pin VFQFPN package for space-constrained PCB layouts. Verify that the 1.08V-1.32V supply range aligns with the system's power architecture. Ensure the host controller supports the available digital interfaces (I2C, SPI, UART, USB).

RF Receivers Part Context

The STA8089FGAD belongs to STMicroelectronics' Teseo III family of GNSS receivers. This series is designed to provide high-performance positioning with low power consumption. The family typically integrates LNA, mixer, and baseband processing into a single package, reducing BOM complexity. It targets applications requiring robust satellite signal acquisition and tracking in challenging environments.

RF Receivers Replacement Considerations

Check for direct substitutes within the Teseo III family, such as the STA8089FGADTR-BG, which may differ in packaging (reel vs. tray) but share core functionality. Verify pin-to-pin compatibility and software compatibility before substitution. Ensure any replacement maintains the same AEC-Q100 qualification if used in automotive applications.
