Product details
Overview
STA8089FG 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, <1 s hot-start TTFF, and embedded 16 Mbit SQI Flash memory - deployed in automotive telematics, fleet tracking, and portable navigation devices.
For engineers reviewing the STA8089FG datasheet, STA8089FG pinout, STA8089FG application, or STA8089FG equivalent, key selection considerations include multi-constellation RF front-end performance, ARM946 MCU integration (196 MHz), dual CAN interfaces, USB 2.0 full-speed PHY, and VFQFPN56 package compatibility with STA8088FG.
Technical Context
The STA8089FG integrates a dedicated G3BB+ baseband processor handling simultaneous multi-constellation signal acquisition and tracking, with RF down-conversion paths optimized for GPS/Galileo (1575.42 MHz → 4.092 MHz), GLONASS (1601.718 MHz → 8.57 MHz), and BeiDou (1561.098 MHz → 10.23 MHz). It embeds a high-performance ARM946E-S core running up to 196 MHz with 256 KB SRAM and on-chip voltage regulation for RF (1.2 V), digital core (1.1 V), and I/O rings (1.8 V / 3.3 V).
Its communication subsystem includes three UARTs (with BOOT0/BOOT1/BOOT2/BOOT3 support), one I²C master, one SSP/SPI interface, two CAN 2.0B controllers, USB 2.0 full-speed transceiver (12 Mbps), and a 10-bit dual-channel SAR ADC - all managed via APB and AHB buses with dedicated clock domains and power management units (PMU) enabling deep standby with RTC and backup domain retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Constellations | GPS, Galileo, GLONASS, BeiDou, QZSS - enables robust positioning in urban canyons and weak-signal environments via multi-system signal fusion. |
| Tracking Channels | 48 parallel channels - supports concurrent satellite tracking across constellations for sub-meter accuracy and rapid reacquisition. |
| Indoor Sensitivity | -162 dBm (tracking mode) - allows reliable position lock indoors or under dense foliage using low-noise amplifier and optimized RF chain. |
| TTFF (Cold Start) | ≤30 s - achieved via fast acquisition engine and embedded flash-stored ephemeris/almanac data, reducing dependency on host system. |
| MCU Core | ARM946E-S @ up to 196 MHz - provides real-time navigation computation, firmware execution, and peripheral control without external processor. |
| Embedded Memory | 256 KB SRAM + 16 Mbit SQI Flash - stores GNSS firmware, navigation algorithms, and user data; eliminates need for external memory components. |
| Operating Voltage | VINL = 1.8 V ±5%; VDD = 1.0–1.32 V; VCC_RF = 1.2 V ±10%; VddIO = 1.8 V ±5% or 3.3 V ±10% - supports flexible power architecture with internal LDOs. |
| Ambient Temp Range | -40°C to +85°C - qualified for automotive and industrial environments per AEC-Q100 stress test requirements. |
Pinout & Package
STA8089FG is housed in a VFQFPN56 (7 × 7 × 1.0 mm, 0.4 mm pitch) package with exposed thermal pad. Pin functions are validated per STMicroelectronics DS10716 Rev 9, including dedicated RF inputs (LNA_IN, XTAL_IN/XTAL_OUT), dual CAN transceivers (CAN0/CAN1 TX/RX), USB DP/DM, and multi-function GPIOs with alternate roles for SPI, I²C, UART, and SQI Flash interface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LNA_IN | RF Front-End Input | Single-ended 1.2 V input for GPS/Galileo/GLONASS/BeiDou RF signals; connects directly to antenna or SAW filter output. |
| XTAL_IN / XTAL_OUT | 32.768 kHz Crystal Interface | Drives internal RTC oscillator; supports external crystal or TCXO for precise timekeeping during standby and navigation. |
| CAN0_TX / CAN0_RX CAN1_TX / CAN1_RX |
Controller Area Network | Dual independent CAN 2.0B interfaces with configurable I/O voltage (3.3 V), enabling vehicle bus integration and sensor fusion. |
| USB_DP / USB_DM | USB 2.0 Full-Speed PHY | Integrated transceiver supports 12 Mbps data transfer; eliminates need for external USB PHY chip in host-connected applications. |
| SPI_DI / SPI_DO / SPI_CLK / SPI_CSN | SQI Flash Interface | Quad-SPI interface for 16 Mbit in-package Flash; enables firmware updates and data logging without external memory footprint. |
| ADC_IN1 / ADC_IN2 | Analog-to-Digital Converter | Two 10-bit SAR ADC inputs (0–1.4 V range); used for battery monitoring, temperature sensing (TSENSE), or auxiliary analog signal acquisition. |
Key Features
| Feature | Design Value |
|---|---|
| Multi-constellation GNSS Engine | G3BB+ baseband processor with 48 tracking + 2 fast-acq channels delivers continuous position fix across GPS/Galileo/GLONASS/BeiDou/QZSS - critical for global deployment. |
| Embedded ARM946 MCU | 196 MHz core with 256 KB SRAM executes full GNSS stack (acquisition, tracking, navigation, NMEA output) autonomously - no host CPU required. |
| In-package SQI Flash | 16 Mbit Flash integrated in same VFQFPN56 package stores firmware, almanac, and user data - reduces BOM count and PCB area vs. discrete Flash solutions. |
| Dual CAN 2.0B Interfaces | Two independent CAN controllers with 3.3 V I/O support vehicle network connectivity (e.g., OBD-II, ADAS sensors) and redundancy in safety-critical systems. |
| USB 2.0 Full-Speed PHY | On-chip USB transceiver enables direct connection to PC or host MCU at 12 Mbps - simplifies development, debugging, and field firmware updates. |
| RTC with Backup Domain | Real-time clock retains time/date during main power loss using VINB (1.6–4.3 V) supply and VOB (1.0 V) output - ensures accurate time stamping for location logs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-constellation GNSS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STA8088FG | Pin-to-pin compatible but lacks embedded 16 Mbit SQI Flash and TESEO-DRAW dead reckoning support; identical RF/baseband and MCU specs. | No on-chip Flash requires external memory for firmware storage; unsuitable for space-constrained or OTA-update-dependent designs. | Select when cost optimization is prioritized and external Flash is acceptable; verify firmware partitioning and boot sequence changes. |
| u-blox UBX-M8030 | Supports same GNSS constellations but uses external Flash and separate MCU; lower RF sensitivity (-160 dBm) and no integrated CAN or USB PHY. | Requires additional components for USB connectivity and CAN bus interface; higher BOM count and larger PCB footprint. | Choose for legacy u-blox ecosystem integration or where modular architecture (separate GNSS + host MCU) is preferred. |
Compared with STA8088FG, STA8089FG adds in-package Flash and enhanced firmware flexibility; versus UBX-M8030, it delivers tighter integration (CAN/USB/Flash/MCU), smaller form factor, and superior indoor sensitivity - making it optimal for compact, self-contained GNSS modules.

FAQ
Is STA8089FG pin-compatible with STA8088FG?
Yes, STA8089FG is pin-to-pin compatible with STA8088FG per STMicroelectronics documentation (DS10716 Rev 9). Both use the VFQFPN56 package with identical pinout, allowing drop-in replacement in existing designs - though firmware and Flash initialization must be updated to leverage the embedded 16 Mbit SQI memory.
Does STA8089FG support dead reckoning functionality?
Only the STA8089FGBD variant supports STMicroelectronics' TESEO-DRAW dead reckoning firmware. The standard STA8089FG does not include this capability; it relies solely on satellite-based positioning. Dead reckoning requires inertial sensor inputs and specialized firmware not present in the base FG version.
What are the power supply requirements for the RF section?
The RF section requires three dedicated 1.2 V supplies: VCC_RF (LNA and RF chain), VCC_PLL (PLL circuit), and VCC_CHAIN (IF processing). Each must be decoupled with 100 nF + 10 nF capacitors per ST's layout guidelines; deviation beyond ±10% tolerance risks degraded sensitivity or acquisition failure.
Can STA8089FG operate without an external crystal?
No - STA8089FG requires a 32.768 kHz external crystal connected to XTAL_IN/XTAL_OUT for RTC operation and system timing stability. While the main GNSS clock derives from internal PLLs locked to GPS/Galileo carrier frequencies, the 32 kHz crystal is mandatory for backup domain functionality and low-power standby timing.
