Product details
Overview
STA8089FGB 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 196 MHz ARM946 MCU with 256 KB SRAM and 16 Mbit in-package SQI Flash - deployed in automotive telematics, asset trackers, and precision timing modules.
For engineers reviewing the STA8089FGB datasheet, STA8089FGB pinout, STA8089FGB application, or STA8089FGB equivalent, key selection considerations include multi-constellation RF front-end architecture, dual CAN interface support, RTC/backup power domain operation, and pin-to-pin compatibility with STA8088FG for legacy design migration.
Technical Context
The STA8089FGB integrates a dedicated G3BB+ baseband processor handling simultaneous signal acquisition and tracking across five GNSS constellations using a shared RF chain with configurable IF downconversion (4.092 MHz for GPS/Galileo, 8.57 MHz for GLONASS, 10.23 MHz for BeiDou), plus embedded ST-DRAW dead reckoning firmware capability in the FGBD variant.
Its subsystem architecture couples a high-performance ARM946E-S core (196 MHz) with tightly coupled memory (16 KB I-TCM / 128 KB D-TCM), dual CAN 2.0B controllers, USB 2.0 full-speed PHY, three UARTs, one I²C master, one SSP (SPI-compatible), 10-bit dual-channel ADC, and RTC with backup domain powered by VINB (1.6–4.3 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Constellations | GPS, Galileo, GLONASS, BeiDou, QZSS - enables global positioning resilience in urban canyons and partial sky view. |
| Tracking Channels | 48 parallel channels - supports concurrent satellite signal processing across all constellations for high-accuracy PVT solutions. |
| Indoor Sensitivity | -162 dBm (tracking mode) - allows reliable position lock indoors or under dense foliage without external LNA. |
| TTFF (Cold Start) | ≤30 s - achieved via embedded flash-stored ephemeris and assisted GNSS data handling in firmware. |
| MCU Core | ARM946E-S @ up to 196 MHz - delivers real-time navigation computation, protocol stack execution, and host interface management. |
| Embedded Memory | 256 KB SRAM + 16 Mbit SQI Flash - eliminates need for external memory; stores firmware, almanac, and user application code. |
| Operating Temp | -40°C to +85°C - qualified for automotive cabin and industrial outdoor deployment without derating. |
| Supply Voltages | 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. |
Pinout & Package
STA8089FGB is housed in a VFQFPN56 package (7 mm × 7 mm × 1.0 mm, 0.4 mm pitch) with exposed thermal pad. Pin functions are validated per STMicroelectronics DS10716 Rev 9 (pp. 8–13), including dedicated RF, power, communication, and backup-domain terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC_RF / VCC_PLL / VCC_CHAIN | Analog RF supply rails | Independent 1.2 V supplies isolate noise-sensitive RF sections from digital domains. |
| VINL1 / VINL2 / VINB | Main & backup LDO inputs | VINL1 powers LDO1 (1.1 V core); VINB (1.6–4.3 V) sustains RTC and backup RAM during main power loss. |
| RTC_XTI / RTC_XTO | 32.768 kHz crystal interface | Enables autonomous timekeeping and low-power wake-up timing independent of GNSS lock. |
| CAN0_RX / CAN0_TX / CAN1_RX / CAN1_TX | CAN 2.0B physical layer I/O | Dual isolated CAN interfaces support vehicle bus integration and redundancy-critical telemetry. |
| USB_DP / USB_DM | Integrated USB 2.0 FS PHY | Full-speed (12 Mbps) USB interface with on-chip transceiver eliminates external PHY component. |
| SPI_DI / SPI_DO / SPI_CLK / SPI_CSN | Quad-SPI Flash interface | Direct connection to embedded 16 Mbit SQI Flash; also supports boot-from-Flash and firmware updates. |
| ADC_IN1 / ADC_IN2 | Analog sensor inputs | 10-bit SAR ADC channels (0–1.4 V range) for battery voltage monitoring or external sensor interfacing. |
| STDBYn / STDBY_OUT / WAKEUP | Power management control | Hardware-controlled low-power standby with programmable wake sources (RTC, CAN, GPIO, USB). |
Key Features
| Feature | Design Value |
|---|---|
| Multi-constellation GNSS engine | Simultaneous GPS/Galileo/GLONASS/BeiDou/QZSS tracking - improves positional accuracy and availability in obstructed environments. |
| Embedded ST-DRAW firmware support | Dead reckoning capability (FGBD variant only) - maintains position estimate during GNSS signal outages using inertial and vehicle dynamics data. |
| Dual CAN 2.0B controllers | Independent CAN buses with message filtering and FIFO buffering - enables robust automotive network integration and diagnostics. |
| In-package 16 Mbit SQI Flash | Eliminates external memory footprint and reduces BOM cost; supports secure firmware storage and field updates. |
| Backup power domain with RTC | Retains time, configuration, and last-known position during main power loss - critical for rapid cold-start recovery. |
| Flexible I/O voltage support | VddIO_R1 (1.8 V or 3.3 V) and VddIO_R2 (3.3 V) allow direct interfacing with mixed-voltage peripherals without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar GNSS receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| u-blox UBX-M8030 | 48-channel GPS/Galileo/GLONASS/BeiDou; no embedded MCU or Flash; requires external host processor and memory. | Lacks integrated ARM946 and 16 Mbit Flash - suitable for host-driven architectures but increases system complexity and BOM count. | Select when leveraging existing host CPU and requiring maximum flexibility in firmware customization. |
| Qualcomm Snapdragon GNSS Platform (e.g., WCN3680) | Integrated into SoC with cellular modem; GNSS functionality shares resources with LTE/Wi-Fi; no standalone GNSS mode. | Not a drop-in replacement - designed for mobile handsets, not embedded telematics; lacks CAN, RTC backup, and industrial temp rating. | Choose only for smartphone-class designs where GNSS is secondary to connectivity and power efficiency dominates. |
Compared with u-blox UBX-M8030 and Qualcomm's SoC-integrated GNSS, STA8089FGB delivers self-contained positioning with deterministic real-time performance, dual CAN for automotive bus coupling, and VINB-backed RTC for guaranteed time continuity - making it optimal for safety-aware, resource-constrained embedded systems.

FAQ
Does STA8089FGB support dead reckoning firmware?
STA8089FGB itself does not include ST-DRAW dead reckoning firmware; that capability is exclusive to the STA8089FGBD variant. The FGB part shares identical hardware and pinout but ships with standard GNSS-only firmware. Firmware upgrade to ST-DRAW requires reprogramming via JTAG or USB and validation against ST's TESEO-DRAW license terms.
What is the role of VINB and how is it used in low-power operation?
VINB (1.6–4.3 V) powers the backup domain, sustaining RTC operation, backup RAM contents, and wake-up logic during main power loss. When VINL is removed, the device enters standby with STDBY_OUT asserted low; VINB maintains timekeeping and enables wake events via CAN, RTC alarm, or GPIO - enabling sub-1 µA retention current and rapid resumption.
Can STA8089FGB operate without an external crystal?
No - STA8089FGB requires a 32.768 kHz crystal connected to RTC_XTI/RTC_XTO for RTC functionality and a 26 MHz or 38.4 MHz reference oscillator (via XTAL_IN/XTAL_OUT) for RF synthesizer and baseband clocking. The device lacks internal RC oscillators capable of meeting GNSS timing stability requirements.
Is the embedded 16 Mbit Flash accessible for user application storage?
Yes - the in-package SQI Flash is fully accessible via the SPI interface (SPI_DI/SPI_DO/SPI_CLK/SPI_CSN) and mapped into the ARM946's address space. It supports XIP (execute-in-place), firmware updates, NVM parameter storage, and logging buffers - all managed through ST's Teseo SDK and HAL drivers without external memory controllers.
