RF Receivers Procurement Notes

Verify the specific suffix 'BG' or 'GA' against the datasheet to confirm exact voltage domains and interface configurations. Ensure the ordering part number matches the required pinout compatibility with existing designs. Confirm RoHS compliance status and AEC-Q100 qualification requirements for automotive integration. Check for any recent product change notices affecting firmware or electrical parameters before finalizing procurement.

RF Receivers Selection Notes

Select this component for applications requiring high sensitivity and fast Time-To-First-Fix in challenging environments. Consider the integrated MCU capabilities if external processing resources are limited. Verify power supply constraints across all voltage rails including digital, RF core, and IO ring voltages. Ensure the VFQFPN package dimensions fit within the available PCB space and thermal management requirements.

RF Receivers Part Context

This part belongs to the Teseo III family of GNSS receivers. It is designed as a drop-in replacement for previous generations like the STA8088GA, maintaining pin-to-pin compatibility while enhancing performance. The series targets the automotive market with robust qualification standards and comprehensive firmware support for various global navigation satellite systems.

RF Receivers Replacement Considerations

The STA8088GA is a pin-compatible alternative within the same family. Verify that the target application does not require specific features unique to the STA8089GAD variant, such as dedicated dead reckoning firmware support. Ensure that the firmware migration path is compatible between the two devices.
