Product details
Overview
STA8089FGBD from STMicroelectronics is a fully integrated, single-die 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 ARM946 MCU (196 MHz), 256 KB SRAM, and 16 Mbit in-package SQI Flash - deployed in automotive dead reckoning and precision navigation systems.
For engineers reviewing the STA8089FGBD datasheet, STA8089FGBD pinout, STA8089FGBD application, or STA8089FGBD equivalent, key selection considerations include multi-constellation RF front-end performance, TESEO-DRAW firmware support, dual CAN interface integration, USB 2.0 full-speed PHY, and VFQFPN56 package compatibility with STA8088FG.
Technical Context
The STA8089FGBD integrates a multi-band RF front-end with dedicated LNA, down-conversion paths for GPS/Galileo (1575.42 MHz → 4.092 MHz), GLONASS (1601.718 MHz → 8.57 MHz), and BeiDou (1561.098 MHz → 10.23 MHz), plus dual independent CAN 2.0B controllers and a 10-bit dual-channel SAR ADC with 0–1.4 V input range.
Its G3BB+ baseband processor handles real-time correlation across all constellations, while the ARM946E-S core executes navigation algorithms and TESEO-DRAW dead reckoning firmware directly from embedded Flash - eliminating external memory requirements and enabling autonomous operation under signal-denied conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Constellations | GPS, Galileo, GLONASS, BeiDou, QZSS - simultaneous multi-system tracking improves position fix reliability in urban canyons and partial sky view. |
| Tracking Channels | 48 channels + 2 fast-acquisition channels - enables concurrent satellite signal processing across multiple frequencies and constellations. |
| Indoor Sensitivity | -162 dBm (tracking mode) - supports continuous positioning indoors or under dense foliage using weak-signal correlation techniques. |
| TTFF Performance | <1 s hot start, 30 s cold start - achieved via on-chip Flash-stored ephemeris and fast acquisition engine with parallel search architecture. |
| MCU Core | ARM946E-S @ up to 196 MHz - provides real-time navigation computation, firmware execution (including TESEO-DRAW), and peripheral control without external host. |
| Embedded Memory | 256 KB SRAM + 16 Mbit SQI Flash - stores firmware, almanac, ephemeris, and runtime variables; eliminates need for external memory components. |
| Operating Voltage | VINL: 1.8 V ±5%; VDD: 1.0–1.32 V; VCC_RF/VCC_PLL: 1.2 V ±10%; VddIO: 1.8 V ±5% or 3.3 V ±10% - supports flexible power domain partitioning and low-power standby modes. |
| Ambient Temp Range | -40°C to +85°C - qualified for automotive cabin and industrial outdoor deployment without derating. |
Pinout & Package
STA8089FGBD 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, Figures 2–3 and Tables 1–6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC_RF / VCC_PLL / VCC_CHAIN | Analog RF supply rails | Independent 1.2 V supplies for RF chain, PLL, and analog front-end - enable noise isolation and optimized power sequencing. |
| XTAL_IN / XTAL_OUT | 32.768 kHz crystal interface | Drives internal RTC oscillator; supports external TCXO or crystal for timing stability critical to GNSS correlation accuracy. |
| CAN0_RX / CAN0_TX / CAN1_RX / CAN1_TX | Dual CAN 2.0B transceiver I/Os | Direct connection to automotive CAN buses without level-shifting or external transceivers - supports vehicle telematics and ADAS integration. |
| USB_DP / USB_DM | USB 2.0 full-speed physical layer | Integrated USB PHY enables direct PC/host connectivity for firmware updates, NMEA streaming, and configuration - no external USB controller required. |
| LNA_IN | RF front-end input | Single-ended 50 Ω input for active GPS antenna; internal LNA provides 17 dB gain and 1.8 dB NF - minimizes external BOM for high-sensitivity reception. |
| ADC_IN1 / ADC_IN2 | Analog sensor inputs | 10-bit SAR ADC channels with 0–1.4 V input range - used for vehicle motion sensors (e.g., wheel speed, IMU bias monitoring) in TESEO-DRAW dead reckoning. |
| RSTn / STDBYn / WAKEUP | Power management control | Asynchronous reset, hardware standby entry, and wake event detection - enable ultra-low-power (<10 µA backup mode) operation with RTC persistence. |
Key Features
| Feature | Design Value |
|---|---|
| TESEO-DRAW firmware support | Enables inertial dead reckoning during GNSS outages using CAN bus vehicle speed and ADC-coupled sensor data - maintains positional continuity in tunnels or urban canyons. |
| Pin-to-pin compatibility with STA8088FG | Allows drop-in replacement in existing designs without PCB rework - accelerates migration to enhanced multi-constellation performance and embedded Flash. |
| Integrated USB 2.0 PHY | Eliminates need for external USB transceiver IC - reduces system cost, board area, and EMI risk while enabling field-upgradable firmware and real-time NMEA output. |
| Dual CAN 2.0B interfaces | Supports simultaneous connection to powertrain and infotainment CAN buses - enables time-synchronized GNSS/vehicle data fusion for fleet tracking and predictive maintenance. |
| In-package 16 Mbit SQI Flash | Stores full GNSS firmware, almanac, and calibration data - removes external Flash chip, simplifies BOM, and ensures secure, tamper-resistant firmware storage. |
| Multi-rail voltage flexibility | VINB (1.6–4.3 V), VINL (1.8 V), VDD (1.0–1.32 V), VddIO (1.8/3.3 V) - accommodates diverse power architectures including battery-backed RTC and automotive 12 V supply regulation schemes. |

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 Flash or ARM MCU - requires external host processor and memory. | Targeted at host-processor-based designs; lacks standalone dead reckoning capability and integrated USB PHY. | Select when leveraging existing host MCU infrastructure and prioritizing vendor-neutral NMEA output over firmware autonomy. |
| Qualcomm WGR7640 | Multi-GNSS + LTE Cat-M1 SoC; integrated cellular modem but no CAN interfaces or TESEO-DRAW firmware stack. | Optimized for direct cellular-connected trackers; higher power consumption and larger footprint than STA8089FGBD. | Select when end-to-end wireless connectivity (LTE + GNSS) is mandatory and CAN bus integration is not required. |
Compared with u-blox UBX-M8030 and Qualcomm WGR7640, STA8089FGBD uniquely combines standalone operation (no host MCU needed), dual CAN for vehicle bus integration, and TESEO-DRAW dead reckoning - making it optimal for cost-sensitive, space-constrained automotive and industrial GNSS nodes requiring signal resilience and firmware autonomy.

FAQ
Does STA8089FGBD require an external crystal oscillator?
No. STA8089FGBD includes an internal 32.768 kHz oscillator amplifier circuit and supports direct connection of a standard 32.768 kHz tuning-fork crystal to XTAL_IN/XTAL_OUT pins. This oscillator drives the real-time clock and provides timing reference for GNSS correlation, eliminating need for external oscillator modules.
What firmware is preloaded on the embedded 16 Mbit SQI Flash?
The embedded Flash contains STMicroelectronics' complete GNSS firmware stack - including acquisition, tracking, navigation, NMEA output, and TESEO-DRAW dead reckoning - pre-programmed at factory. No external Flash programming is required for basic operation; firmware updates are performed via USB or UART using ST's official tools.
Can STA8089FGBD operate without CAN bus connections?
Yes. CAN0 and CAN1 pins are multiplexed with UART and GPIO functions. When CAN is unused, those pins default to UART0/UART2 or general-purpose I/O per AF0/AF1 configuration. The device operates fully in GNSS-only mode with USB, UART, or SPI interfaces active - CAN functionality is optional and software-configurable.
How is power managed during vehicle ignition-off conditions?
STA8089FGBD supports backup operation via VINB (1.6–4.3 V), which powers the RTC, BKRAM, and wake logic. When main supply (VINL) is removed, the IC enters ultra-low-power standby (<10 µA) while retaining time, almanac, and last-known position - enabling instant hot starts upon re-powering without full cold acquisition.
