• Telematics units for fleet management
• Personal navigation devices (PND)
• IoT tracking modules requiring multi-constellation support

RF Receivers Procurement Notes

Verify the specific suffix BG against the official datasheet to confirm pinout and thermal pad configuration. Check RoHS compliance status as indicated in the manufacturer documentation. Confirm availability through authorized distributors since some variants may be discontinued or have limited stock. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

RF Receivers Selection Notes

Select this component when multi-constellation support is required for improved positioning accuracy in challenging environments. Consider the 56-lead QFPN package size for PCB layout constraints. Evaluate power consumption requirements against the 1.08 V to 1.32 V operating range. Verify interface compatibility with the host microcontroller for I2C or SPI connectivity.

RF Receivers Part Context

This part belongs to the STA8089 family of GNSS receivers designed for automotive and mobile applications. It integrates RF front-end and baseband processing on a single die. The TR-BG variant specifies tape-and-reel packaging for automated surface-mount assembly. It replaces older single-constellation solutions with unified multi-system capability.

RF Receivers Replacement Considerations

Check for direct substitutes within the STA8089 series such as STA8089FG. Verify pin-to-pin compatibility before substitution. Review updated datasheets for any changes in electrical characteristics or package dimensions. Ensure firmware compatibility if migrating between similar receiver models.
