RF Receivers Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm that the specific suffix matches the required automotive grade specifications. Ensure handling procedures comply with moisture sensitivity level requirements during storage and assembly. Validate package integrity against the 56-VFQFN exposed pad configuration prior to installation.

RF Receivers Selection Notes

Select this component when multi-constellation GNSS capability is required in an automotive environment. The integrated RF design reduces external component count compared to discrete solutions. Verify interface compatibility with the host microcontroller, as the device supports multiple communication protocols including SPI and UART. Consider the thermal performance within the specified operating temperature range for enclosed automotive enclosures.

RF Receivers Part Context

This part belongs to the STA8089FGA series of GNSS receivers designed for high-performance positioning applications. The series emphasizes integration by embedding RF functions directly into the silicon die. This approach minimizes board space and simplifies layout constraints for system designers working within strict automotive packaging limitations.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the STA8089FGATR-BG variant for potential pin-compatible alternatives if different suffix configurations are required. Cross-reference with other STMicroelectronics GNSS products only after verifying electrical parameter alignment and interface compatibility.
