STA8089FGAD48

RF Receivers Overview

The STA8089FGAD48 is a fully integrated GNSS receiver from the Teseo III family, supporting GPS, Galileo, GLONASS, BeiDou, and QZSS. It features a single-die design with embedded RF front-end, 256 Kbyte SRAM, and 16 Mbits in-package SQI Flash memory. The device includes an ARM946 MCU operating up to 196 MHz, 48 tracking channels, and two fast acquisition channels. Key electrical parameters include a main voltage of 1.8 V ± 5%, backup voltage of 1.6–4.3 V, digital voltage of 1.0–1.32 V, and RF core voltage of 1.2 V ± 10%. It offers -162 dBm indoor sensitivity, TTFF < 1 s (hot start), and interfaces via UART, I2C, SPI, USB 2.0, and CAN.

RF Receivers Procurement Notes

Verify that the specific suffix 'D48' corresponds to the tape-and-reel packaging configuration rather than tray packaging, as distributor listings may vary. Confirm AEC-Q100 automotive qualification status for the specific batch. Ensure compatibility with existing board layouts designed for the VFQFPN56 package dimensions. Check for required external components such as crystal oscillators or power filters as specified in the reference schematic.

RF Receivers Selection Notes

Select this component when a standalone GNSS solution with integrated memory and processing is required to minimize external BOM. It is suitable for applications needing fast cold-start performance and high sensitivity. Consider the pin-to-pin compatibility with the STA8088FG if migrating from previous generations. Evaluate the need for dead reckoning capabilities, which are supported by specific firmware variants like TESEO-DRAW.

RF Receivers Part Context

The STA8089FGAD48 belongs to the Teseo III product family from STMicroelectronics. This series is designed for robust positioning in challenging environments. The device represents a significant integration level compared to earlier generations, embedding both RF and baseband functions on a single die. It targets automotive and industrial markets requiring high reliability and multi-constellation support.

RF Receivers Replacement Considerations

The datasheet explicitly states backward compatibility with the STA8088FG, enabling direct pin-to-pin migration. No other substitute part numbers are publicly confirmed in the provided documentation.
