Product details
Overview
STA8089FGTR from STMicroelectronics is a fully integrated, single-die GNSS receiver IC supporting GPS, Galileo, GLONASS, BeiDou, and QZSS with 48 tracking + 2 fast acquisition channels, -162 dBm indoor tracking sensitivity, sub-1-second hot TTFF, and embedded 16 Mbit SQI Flash memory - deployed in automotive telematics, asset trackers, and precision timing modules.
For engineers reviewing the STA8089FGTR datasheet, STA8089FGTR pinout, STA8089FGTR application, or STA8089FGTR equivalent, key selection considerations include multi-constellation RF front-end performance, ARM946 MCU integration (196 MHz), dual CAN 2.0B interfaces, USB 2.0 full-speed PHY, and VFQFPN56 package compatibility with STA8088FG.
Technical Context
The STA8089FGTR integrates a G3BB+ baseband processor with dedicated correlator engines for simultaneous multi-constellation signal processing, including GPS L1 C/A, Galileo E1, GLONASS L1, BeiDou B1I, and QZSS L1CA. Its RF front-end uses a direct-conversion architecture with integrated LNA and dual-path VGA filtering to support 1575.42 MHz (GPS/Galileo/QZSS), 1601.718 MHz (GLONASS), and 1561.098 MHz (BeiDou) bands.
It embeds an ARM946E-S core running at up to 196 MHz with 16 KB I-Cache, 8 KB D-Cache, and 144 KB switchable TCM (7×16 KB), coupled with on-chip peripherals including two CAN controllers, three UARTs, one I²C master, one SSP/SPI interface, 10-bit dual-channel ADC, RTC, and 32-bit watchdog timer - all powered via five independent LDOs with configurable voltage domains.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STA8088FGTR | Pin-to-pin compatible; identical RF/baseband but lacks embedded 16 Mbit Flash - requires external SPI Flash for firmware storage. | No in-package memory; higher BOM count and PCB area needed for external Flash and associated decoupling. | Select when legacy design reuse is critical and external Flash is already present in system architecture. |
| u-blox UBX-M8030-KT | 33-channel GPS/Galileo/GLONASS; no ARM MCU - relies on host processor for navigation computation and NMEA handling. | Requires external host MCU and firmware stack; no standalone operation or embedded Flash. | Select when host processor resources are available and lower-cost module integration is prioritized over self-contained operation. |
Compared with STA8088FGTR, STA8089FGTR adds 16 Mbit in-package Flash for autonomous firmware execution; compared with UBX-M8030-KT, it delivers full standalone functionality with integrated ARM946 MCU and dual CAN - reducing system-level complexity and component count.

FAQ
Does STA8089FGTR support dead reckoning (DR) functionality?
No - DR capability (TESEO-DRAW) is exclusive to the STA8089FGBD variant, which includes additional firmware licensing and hardware configuration. The STA8089FGTR supports only standard GNSS positioning, acquisition, tracking, and navigation functions as defined in the DS10716 datasheet.
What is the maximum operating frequency of the ARM946E-S core in STA8089FGTR?
The ARM946E-S core operates at up to 196 MHz under nominal conditions (VDD = 1.1 V, ambient ≤85°C), as specified in Section 4.2 of DS10716 Rev 9. Performance scales linearly with supply voltage and is constrained by thermal limits in sustained compute workloads.
Can STA8089FGTR be powered directly from a 1.2 V supply?
Yes - applying 1.2 V to VDDD bypasses the internal LDOs, placing them in power-down mode. This configuration is explicitly supported per Section 4.6 of DS10716 Rev 9 and reduces total system power consumption when external regulation is available.
Is the 16 Mbit SQI Flash accessible for user data storage?
Yes - the embedded Flash is memory-mapped and partitionable via firmware. While factory-programmed with GNSS firmware, up to 8 Mbit can be allocated for application data logging, configuration storage, or OTA update staging - subject to ST's Teseo firmware API constraints.
