Product details
Overview
STA8089GADTR from STMicroelectronics is an AEC-Q100 qualified, single-die automotive GNSS receiver IC supporting GPS, Galileo, GLONASS, BeiDou, and QZSS with 48 tracking + 2 fast acquisition channels. It integrates RF front-end, LNA, ARM946 MCU (up to 196 MHz), 256 KB SRAM, USB 2.0 full-speed PHY, dual CAN, dual UART, I²C, SQI Flash interface, RTC, and 10-bit dual ADC - deployed in in-dash navigation and OEM telematics systems.
For engineers reviewing the STA8089GADTR datasheet, STA8089GADTR pinout, STA8089GADTR application, or STA8089GADTR equivalent, key selection criteria include multi-constellation sensitivity (–162 dBm tracking), cold-start TTFF (<30 s), automotive-grade voltage regulation (VINL: 1.8 V ±5%, VCC: 1.2 V ±10%), VFQFPN56 package compatibility, and TESEO-DRAW dead reckoning firmware support (STA8089GAD variant).
Technical Context
The STA8089GADTR implements a dual-path RF front-end with dedicated signal paths for GALGPS (1575.42 MHz → 4.092 MHz) and GNSCOM (GLONASS/BeiDou at 1601.718/1561.098 MHz → 8.57/10.23 MHz), each feeding a 3-bit sign-magnitude ADC and VGA controlled via SPI. Its G3BB+ baseband processor performs simultaneous acquisition and tracking across up to four constellations, with GLONASS and BeiDou mutually exclusive in concurrent mode.
The embedded ARM946E-S core runs at up to 196 MHz and manages all GNSS firmware operations - including navigation solution computation, NMEA output, and sensor fusion readiness for TESEO-DRAW. Power management includes three independent LDOs (LDO1/LDO2/BKLDO), backup domain with RTC, and dual I/O rings supporting 1.8 V or 3.3 V logic levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Constellations | GPS, Galileo, GLONASS, BeiDou, QZSS - enables global positioning coverage with urban canyon resilience via multi-system signal fusion. |
| Tracking Channels | 48 channels + 2 fast-acquisition channels - supports concurrent satellite tracking across multiple frequencies and constellations for high-accuracy PVT solutions. |
| Indoor Sensitivity | –162 dBm (tracking mode) - allows reliable position lock indoors or under dense foliage using weak-signal correlation techniques. |
| Time-to-First-Fix | Hot start <1 s; Cold start <30 s - achieved via on-chip ephemeris storage, fast oscillator startup, and optimized acquisition search space. |
| MCU Core | ARM946E-S @ up to 196 MHz - executes full GNSS stack (acquisition, tracking, navigation, NMEA output) without external host processor. |
| Integrated Peripherals | Dual CAN 2.0B, dual UART, I²C master/slave, USB 2.0 FS PHY, SQI Flash interface, RTC, 32-bit WDT, 2×10-bit ADC - reduces BOM count and board space in automotive head units. |
| Supply Voltages | VINL = 1.8 V ±5%; VCC = 1.2 V ±10%; VDDIO_R1 = 1.8 V or 3.3 V ±10%; VINB = 1.6–4.3 V - supports flexible power architecture with backup domain retention. |
| Operating Temp | –40°C to +85°C - meets automotive cabin ambient requirements per AEC-Q100 Grade 3 qualification. |
Pinout & Package
STA8089GADTR is housed in a VFQFPN56 (7 mm × 7 mm × 1.0 mm, 0.4 mm pitch) thermally enhanced package with exposed pad for improved heat dissipation in automotive environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL1 / VINL2 | Main digital supply inputs | Accept 1.8 V (±5%) for LDO1/LDO2 input; enable internal regulation of VDDD (1.2 V), VOL1/VOL2 (1.2 V), and VOB (1.0 V). |
| VCC_RF / VCC_PLL / VCC_CHAIN | Analog RF supply rails | 1.2 V ±10% dedicated supplies for RF front-end, PLL, and baseband chain - decoupling critical for phase noise and SNR performance. |

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 |
|---|---|---|---|
| u-blox UBX-M8030-KT | 22 nm process; 72-channel tracking; no integrated MCU; requires external host for NMEA generation and firmware updates. | Lacks ARM946 core and USB PHY - mandates companion microcontroller and additional USB interface components. | Select when prioritizing ultra-low power consumption (<25 mW tracking) and minimal footprint over self-contained firmware execution. |
| Qualcomm Snapdragon GNSS Platform (SDR845) | SoC-based solution with integrated AP; supports L1/L5 dual-frequency but limited BeiDou B1C/GLONASS L3 support in early revisions. | Targets infotainment head units with Android OS; not AEC-Q100 qualified - unsuitable for safety-critical or standalone telematics modules. | Select only for Android-based IVI platforms requiring multimedia co-processing; avoid for ASIL-compliant or discrete GNSS modules. |
Compared with u-blox UBX-M8030-KT and Qualcomm SDR845, STA8089GADTR uniquely combines AEC-Q100 qualification, embedded ARM946 MCU, USB PHY, dual CAN, and full multi-constellation support in a single VFQFPN56 package - reducing system complexity and validation effort for automotive Tier-1 suppliers.

FAQ
Is STA8089GADTR pin-compatible with STA8088GA?
Yes, STA8089GADTR is pin-to-pin compatible with STA8088GA per STMicroelectronics documentation. This enables direct replacement in existing PCB layouts without redesign, preserving mechanical fit, thermal profile, and signal routing integrity while upgrading to enhanced sensitivity, faster TTFF, and expanded QZSS/BeiDou support.
Does STA8089GADTR support dead reckoning functionality?
STA8089GADTR hardware supports TESEO-DRAW dead reckoning firmware, but only the STA8089GAD variant ships with it pre-installed. The GADTR version requires separate firmware loading via USB or SQI Flash; all necessary GPIO, ADC, timer, and CAN resources for IMU sensor fusion are present and documented in the datasheet.
What are the voltage requirements for the I/O rings?
VDDIO_R1 supports 1.8 V ±5% or 3.3 V ±10%; VDDIO_R2 is fixed at 3.3 V. These supplies power UART, CAN, USB, SQI, and GPIO peripherals. Mixing 1.8 V and 3.3 V logic on separate rings is supported, but level translation is required if interfacing externally between rings.
Can STA8089GADTR operate without an external crystal?
No - STA8089GADTR requires a 32.768 kHz crystal connected to XTAL_IN/XTAL_OUT for RTC operation and system clock stabilization. While the RF synthesizer accepts 10–52 MHz reference clocks, the 32.768 kHz crystal is mandatory for backup domain functionality and low-power timing accuracy.
