RF Receivers Procurement Notes

Verify the specific suffix 'GA' against the manufacturer's current product portfolio to confirm availability and pinout compatibility. Ensure the design accommodates the required 1.6V to 3.3V supply rails and interface protocols. Confirm RoHS3 compliance and MSL level 3 handling requirements during assembly. Cross-reference the datasheet revision date to ensure alignment with latest automotive qualification standards.

RF Receivers Selection Notes

Select this component when a fully integrated GNSS solution with embedded RF is required to minimize board space. It is suitable for applications needing support for multiple satellite constellations simultaneously. Consider the TFBGA-99 package constraints and thermal dissipation needs. Verify that the host processor can support the available digital interfaces such as SPI or UART for configuration and data output.

RF Receivers Part Context

The STA8090GA belongs to the STA8090 family of GNSS receivers from STMicroelectronics. This series is designed for high-performance positioning applications requiring robust multi-constellation support. The GA variant specifically targets automotive and industrial markets with integrated RF functionality. It represents a shift towards highly integrated solutions that reduce external component count compared to earlier discrete receiver designs.

RF Receivers Replacement Considerations

The STA8090FG is a related model within the same family offering similar multi-constellation support. Check datasheets for differences in package type, interface options, and specific automotive qualifications before substitution.
