STA8100GASTR

RF Receivers Overview

The STA8100GASTR is an automotive-grade, multi-frequency GNSS receiver IC from STMicroelectronics' Teseo-V family. It integrates an ARM Cortex-M7 core operating up to 314 MHz with extensive memory resources, including 64 KB instruction TCM and 384 KB data TCM. The device supports six constellations (GPS, Galileo, GLONASS, BeiDou, QZSS, NAVIC) across L1, L2, L5, and E6 bands. Key electrical parameters include a supply voltage range of 1.71V to 3.6V and an operating temperature range of -40°C to 105°C. It features 80 tracking channels and 4 fast acquisition channels within an 81-pin LFBGA package.

RF Receivers Feature Summary

• Supports multiconstellation and multi-band GNSS positioning with integrated dead reckoning capabilities via TESEO-DRAW.
• Integrates a high-performance ARM Cortex-M7 microprocessor for complex signal processing and application execution.
• Provides comprehensive measurement outputs including code phase, carrier phase, and Doppler frequency.
• Includes hardware-level antijamming features such as notch filters and robust ESD protection.

RF Receivers Applications

• Automotive navigation and telematics systems requiring AEC-Q100 qualification.
• Advanced driver-assistance systems (ADAS) utilizing dead reckoning integration.
• High-precision positioning modules for connected vehicles.
• Multi-constellation GNSS receivers for global location services.

RF Receivers Procurement Notes

Verify the specific suffix 'GASTR' corresponds to the tape-and-reel packaging variant rather than tray packaging when sourcing components. Confirm that the requested part matches the automotive grade specifications and the 81-pin LFBGA footprint requirements. Ensure compatibility with the required interface protocols and power supply constraints before finalizing procurement orders.

RF Receivers Selection Notes

Select this component for applications demanding simultaneous reception of multiple GNSS constellations and bands. The integrated ARM Cortex-M7 core allows for local processing of dead reckoning data, reducing dependency on external sensors. Consider the 81-pin LFBGA package size and thermal characteristics during PCB layout design. Verify that the system architecture supports the necessary UART, SPI, or I2C interfaces for configuration and data output.

RF Receivers Part Context

The STA8100GASTR belongs to the Teseo-V family of positioning receivers, representing STMicroelectronics' fifth-generation technology. This series is designed to address the increasing complexity of modern navigation requirements by combining RF front-end capabilities with powerful digital signal processing cores. The family emphasizes accuracy, reliability, and integration for automotive and industrial markets.

RF Receivers Replacement Considerations

Direct substitutes within the same family include the STA8100GA (tray package) and STA8100GAD (with dedicated dead reckoning support). When replacing, ensure the pinout and software configuration remain compatible. Note that package variations may affect manufacturing processes but do not alter functional performance.
