STA8089FGTR

RF Receivers Overview

The STA8089FGTR is a fully integrated GNSS receiver from the Teseo III family, supporting GPS, Galileo, GLONASS, BeiDou2, and QZSS. It features 48 tracking channels and 2 fast acquisition channels with embedded RF and in-package SQI Flash Memory (16 Mbits). The device includes an ARM946 MCU operating up to 196 MHz, 256 Kbyte SRAM, and interfaces including UART, I2C, SPI, USB 2.0, and CAN. Operating voltages include VDD at 1.08V–1.32V, VINL at 1.8V±5%, and VINB at 1.6V–4.3V. It operates within -40°C to +85°C in a VFQFN-56 package.

RF Receivers Applications

• Automotive infotainment and telematics systems
• Fleet management and vehicle tracking
• Navigation devices requiring multi-constellation support
• Dead reckoning applications using ST-DRAW firmware

RF Receivers Procurement Notes

Verify the specific suffix 'FGATR' against official STMicroelectronics documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with required voltage domains (VDD, VINL, VINB) and interface protocols (UART, I2C, SPI, USB, CAN) for the target application design. Confirm AEC-Q100 qualification status if automotive reliability is required.

RF Receivers Selection Notes

Select this component for designs requiring a complete GNSS solution without external memories due to its embedded flash and SRAM. Consider the pin-to-pin compatibility with STA8088FG for migration purposes. Evaluate the need for ST-DRAW dead reckoning support, which is available on specific variants like STA8089FGBD. Ensure the system architecture supports the multiple voltage rails and interface requirements specified in the datasheet.

RF Receivers Part Context

The STA8089FGTR belongs to the Teseo III family of GNSS receivers. It is designed as a backward-compatible successor to the STA8088FG, facilitating easier application migration. The device represents a shift towards highly integrated solutions by combining the RF front-end, baseband processing, and microcontroller unit into a single die, reducing board space and complexity for OEMs.

RF Receivers Replacement Considerations

The STA8088FG is pin-to-pin compatible and serves as a direct predecessor. For designs requiring dead reckoning capabilities, the STA8089FGBD variant supports the ST-DRAW firmware. Other members of the Teseo III family may offer similar integration levels but should be verified for specific interface and voltage compatibility.
