STA9100MGASTR

RF Receivers Overview

The STA9100MGASTR is an automotive-grade GNSS measurement engine receiver IC from STMicroelectronics' TeseoAPP family. It supports multi-band positioning across GPS, Galileo, GLONASS, BeiDou, QZSS, and IRNSS constellations. The device features four fast acquisition channels and eighty tracking channels, enabling L2, L5, and E6 signal processing with an external RF front-end. It provides code phase, carrier phase, and Doppler measurements via serial interfaces. Operating within a supply voltage range of 3.0V to 3.6V and temperatures from -40°C to 85°C, it includes embedded hardware security and ISO26262 safety concepts in an LFBGA-81 package.

RF Receivers Feature Summary

• Multi-constellation support for six global navigation satellite systems including GPS, Galileo, and BeiDou
• Multi-band capability for L2, L5, and E6 signals with external RF front-end integration
• High channel capacity with four acquisition and eighty tracking channels
• Embedded hardware security and comprehensive ISO26262 safety concept implementation

RF Receivers Applications

• Automotive precise positioning systems
• Advanced Driver Assistance Systems (ADAS)
• Telematics units requiring high availability
• Fleet management and navigation solutions

RF Receivers Procurement Notes

Verify the specific suffix 'GASTR' indicates tape-and-reel packaging versus 'MGA' tray packaging when sourcing. Confirm AEC-Q100 qualification status and ISO26262 compliance documentation are available from the manufacturer. Ensure the external RF front-end component, such as the STA5635S, is selected for full multi-band functionality. Check regional export control classifications like ECCN 7A994 for international shipments.

RF Receivers Selection Notes

Select this component for applications requiring ASIL-capable precise positioning with multi-band interference mitigation. It is suitable for designs needing simultaneous tracking of multiple GNSS constellations without external baseband processing. Consider the need for an external RF front-end to utilize L2/L5/E6 bands. Evaluate system power constraints against the 3.0V to 3.6V operating range and thermal requirements for automotive environments.

RF Receivers Part Context

This part belongs to the TeseoAPP family, designed for automotive ASIL Precise Positioning applications. It represents STMicroelectronics' fifth-generation positioning receiver technology. The family focuses on integrating safety concepts and hardware security directly into the measurement engine. It complements other ST connectivity solutions by providing high-accuracy location data for connected vehicle architectures.

RF Receivers Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Verify compatibility with existing antenna designs and RF front-end configurations if considering alternative models within the same family or competitor products.
