RF Receivers Procurement Notes

Verify the specific suffix 'G48' against official STMicroelectronics documentation to confirm exact pinout, package dimensions, and environmental compliance status. Ensure compatibility with target board voltage levels and interface requirements before integration. Confirm that the WLCSP-77 package handling procedures meet manufacturing standards for fine-pitch components.

RF Receivers Selection Notes

Select this component for applications requiring minimal bill of materials and small footprint size. It is suitable for cost-sensitive designs needing multi-constellation support without external baseband processing. Consider the integrated power management unit and extensive peripheral interfaces when designing system architecture for space-constrained portable electronics.

RF Receivers Part Context

The STA8090WG48 belongs to the Teseo III product line, designed for low-cost, small-footprint positioning solutions. It combines GNSS reception capabilities with a powerful microcontroller core, enabling standalone operation. This integration reduces system complexity by eliminating the need for separate baseband processors or additional memory chips in many standard applications.

RF Receivers Replacement Considerations

The STA8090WGR is a comparable variant within the same family offering similar functionality. Verify package compatibility and interface configurations when substituting. No other direct public substitutes are confirmed in available documentation.

RF Receivers FAQ
