RF Receivers Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices as this specific suffix variant may be discontinued. Ensure storage conditions meet J-STD-020 standards to prevent damage before reflow soldering.

RF Receivers Selection Notes

Select this component for designs requiring multi-constellation support without external memory. Ideal for automotive infotainment where space constraints favor a single-die solution. Consider pin compatibility with legacy STA8088FG if migrating existing designs. Evaluate power supply requirements across digital, RF, and I/O domains during schematic design.

RF Receivers Part Context

Part of the Teseo III family of GNSS receivers by STMicroelectronics. Designed as a drop-in replacement for older models while offering enhanced processing capabilities. Integrates baseband and RF functions into one package to reduce board size and complexity.

RF Receivers Replacement Considerations

STA8088FG is documented as backward compatible for migration purposes. Verify pinout and firmware compatibility when substituting. No other direct substitutes are confirmed in public documentation.
