Product details
Overview
STA8089FGA from STMicroelectronics is an AEC-Q100 qualified, single-die automotive GNSS receiver IC supporting GPS/Galileo/GLONASS/BeiDou/QZSS with 48 tracking + 2 fast acquisition channels, -162 dBm indoor tracking sensitivity, <1 s hot-start TTFF, and embedded 16 Mbit SQI Flash. It integrates RF front-end, ARM946 MCU (196 MHz), 256 KB SRAM, RTC, dual CAN, USB 2.0 full-speed PHY, and operates from -40°C to +85°C in VFQFPN56.
For engineers reviewing the STA8089FGA datasheet, STA8089FGA pinout, STA8089FGA application, or STA8089FGA equivalent, key selection considerations include multi-constellation timing accuracy in urban canyons, automotive-grade power sequencing (VINL/VINB/VDDIO voltage domains), integrated dead reckoning readiness (STA8089FGAD variant), and pin-to-pin migration path from STA8088FG.
Technical Context
The STA8089FGA implements a fully integrated GNSS baseband processor (G3BB+) 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 ST's CMOSRF technology with on-chip LNA, dual VGA stages, and 3-bit sign-magnitude IF ADCs feeding digital acquisition and tracking loops.
It embeds an ARM946E-S core with 16 KB I-Cache, 8 KB D-Cache, and switchable TCM (7×16 KB), managed by a dedicated PRCC clock generator and PMU with three independent LDOs (LDO1/LDO2/BKLDO) and backup domain logic. Communication is handled via three UARTs (one with BOOT function), dual CAN 2.0B controllers, I²C master, SSP (SPI-compatible), USB 2.0 FS PHY, and SQI interface for in-package Flash.

Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STA8088FG | Same pinout and footprint; lacks ST-DRAW firmware support and has lower Flash density (8 Mbit vs. 16 Mbit) | Targeted at cost-sensitive navigation systems without dead reckoning requirement | Select when legacy design reuse is prioritized and firmware size constraints permit |
| u-blox UBX-M8030-KT | 32-channel GPS/GLONASS only; no BeiDou/Galileo/QZSS; requires external Flash and power management | Used in industrial trackers where multi-constellation coverage is not mandatory | Choose for simpler GNSS needs and established u-blox ecosystem integration |
Compared with STA8088FG, STA8089FGA adds 8 Mbit Flash capacity and ST-DRAW readiness for enhanced dead reckoning, while versus u-blox UBX-M8030-KT it delivers broader constellation support, higher channel count, and full system integration - reducing external component count and improving automotive qualification alignment.

FAQ
Is STA8089FGA pin-compatible with STA8088FG?
Yes, STA8089FGA is fully pin-to-pin compatible with STA8088FG, sharing identical VFQFPN56 footprint, power pin mapping, and peripheral I/O assignments. This allows direct PCB-level replacement and software migration without hardware redesign, provided firmware is updated to leverage the additional Flash and ST-DRAW features.
What GNSS constellations does STA8089FGA support simultaneously?
STA8089FGA supports GPS, Galileo, GLONASS, BeiDou, and QZSS concurrently using its 48 tracking channels. It processes signals across L1/E1/B1I bands with shared correlator resources, enabling true multi-constellation positioning that improves accuracy, availability, and time-to-first-fix in challenging signal environments.
Does STA8089FGA require external Flash memory?
No, STA8089FGA integrates 16 Mbit SQI Flash in-package, eliminating the need for external memory. The Flash stores the complete GNSS firmware stack, almanac, ephemeris data, and user application code, enabling standalone operation and secure over-the-air updates via UART or USB without external storage dependencies.
What is the role of the VINB supply pin?
VINB (1.6–4.3 V) powers the backup domain, including RTC, BKRAM, and wake-up logic. When main supply (VINL) is removed, VINB sustains timekeeping and retains last-known position data, enabling fast cold starts and continuous logging during vehicle ignition cycles - essential for automotive telematics and eCall functionality.
