Product details
Overview
STA8089FGATR 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, -162 dBm indoor tracking sensitivity, <1 s hot-start TTFF, and integrated ARM946 MCU (196 MHz), 256 KB SRAM, and 16 Mbit in-package SQI Flash - deployed in OEM telematics and in-dash navigation systems.
For engineers reviewing the STA8089FGATR datasheet, STA8089FGATR pinout, STA8089FGATR application, or STA8089FGATR equivalent, key selection considerations include multi-constellation timing accuracy under urban canopy, CAN/USB2.0/UART peripheral integration for vehicle bus interfacing, RF front-end co-integration eliminating external LNA filters, and backup power domain support for RTC persistence during ignition-off.
Technical Context
The STA8089FGATR integrates a G3BB+ baseband processor with dedicated correlator engines for simultaneous multi-constellation signal processing, including GPS/Galileo at 1575.42 MHz, GLONASS at 1601.718 MHz, and BeiDou at 1561.098 MHz, downconverted via on-chip RF tuner with embedded LNA and dual VGA control.
Its ARM946 subsystem operates up to 196 MHz with 16 KB I-Cache, 8 KB D-Cache, and switchable 7×16 KB TCM; peripherals include two 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 32.768 kHz crystal interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| GNSS Constellations | GPS, Galileo, GLONASS, BeiDou, QZSS - enables robust positioning in dense urban environments via multi-system redundancy. |
| Tracking Channels | 48 parallel channels - supports simultaneous satellite signal tracking across all constellations without time-slicing latency. |
| Indoor Sensitivity | -162 dBm (tracking mode) - sustains position lock indoors or under partial canopy using high-gain LNA and low-noise RF chain. |
| TTFF (Cold Start) | <30 s - achieves first fix rapidly using embedded 16 Mbit Flash-stored ephemeris and almanac data, eliminating host-fetch dependency. |
| MCU Core | ARM946E-S @ up to 196 MHz - provides real-time navigation computation, firmware execution, and peripheral management without external processor. |
| Supply Voltages | VINL = 1.8 V ±5%, VCC = 1.2 V ±10%, VddIO = 1.8 V ±5% or 3.3 V ±10% - enables direct connection to automotive 1.8 V/3.3 V domains and internal LDO bypass capability. |
| Ambient Temp Range | -40°C to +85°C - meets extended automotive temperature requirements for under-hood and dashboard mounting. |
Pinout & Package
STA8089FGATR 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 DS11809 Rev 3, Section 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL1 / VINL2 | Main LDO input supply | Accepts 1.8 V (VINL1) or 1.6–4.3 V (VINL2) to power digital core and ADC; enables flexible power architecture with external or internal regulation. |
| VCC_RF / VCC_PLL / VCC_CHAIN | Analog RF supply rails | Three independent 1.2 V ±10% supplies isolate noise-sensitive RF sections (LNA, synthesizer, baseband) for optimal SNR and phase noise performance. |
| XTAL_IN / XTAL_OUT | 32.768 kHz crystal interface | Direct connection to low-power oscillator for RTC operation during standby; supports external TCXO or crystal with no additional buffer circuitry. |
| CAN0_RX / CAN0_TX / CAN1_RX / CAN1_TX | CAN 2.0B transceiver I/O | Dual isolated CAN interfaces compliant with ISO 11898-2; support vehicle network integration without external transceivers. |
| USB_DP / USB_DM | USB 2.0 full-speed PHY | Integrated physical layer eliminates need for external USB transceiver; supports 12 Mbps data transfer for firmware updates and NMEA streaming. |
| SPI_DI / SPI_DO / SPI_CLK / SPI_CSN | SQI Flash interface | Quad-SPI interface directly accesses 16 Mbit in-package Flash for firmware storage and runtime code execution - no external memory required. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 2 qualification | Validated for automotive use with zero-defect production flow - ensures reliability in safety-critical telematics and ADAS-adjacent positioning applications. |
| Embedded multi-constellation GNSS firmware | Fully self-contained acquisition, tracking, navigation, and NMEA output - eliminates host CPU dependency and reduces BOM count. |
| ST-DRAW dead reckoning support (STA8089FGAD variant) | Enables continuous positioning during GNSS outages using inertial sensor fusion - requires separate firmware license but shares same hardware platform. |
| Backup power domain with RTC | VINB (1.6–4.3 V) powers RTC and BKRAM during main supply loss - preserves timekeeping and last-known position for faster cold starts. |
| Pin-to-pin compatibility with STA8088FG | Enables drop-in replacement in existing designs - accelerates migration to enhanced sensitivity, faster TTFF, and expanded constellation support. |

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-KT | 33 tracking channels, no integrated MCU or Flash; requires external host processor and memory; supports same GNSS constellations. | Lacks autonomous navigation capability - relies on host for NMEA generation and ephemeris management. | Select when system already includes capable host MCU and design prioritizes minimal footprint over integration. |
| Qualcomm WGR7640 | Supports GPS/Galileo/GLONASS only; integrates LTE modem; uses external Flash; no CAN interface. | Targets cellular-connected asset trackers - not suitable for CAN-based automotive ECUs or standalone navigation. | Select only for dual-mode (GNSS + LTE) portable or fleet devices where cellular connectivity is mandatory. |
Compared with u-blox UBX-M8030-KT and Qualcomm WGR7640, STA8089FGATR uniquely combines multi-constellation GNSS, ARM946 MCU, 16 Mbit Flash, dual CAN, and AEC-Q100 qualification in one die - making it the only option for cost-sensitive, space-constrained, and functionally autonomous automotive positioning nodes.

FAQ
What GNSS constellations does STA8089FGATR support?
STA8089FGATR supports GPS (USA), Galileo (EU), GLONASS (Russia), BeiDou (China), and QZSS (Japan) simultaneously. Its 48-channel baseband processor enables concurrent signal acquisition and tracking across all five systems, improving position availability and accuracy in obstructed environments like urban canyons or under tree cover.
Does STA8089FGATR require external Flash memory?
No. STA8089FGATR integrates 16 Mbit SQI Flash memory inside the VFQFPN56 package. This embedded Flash stores the complete GNSS firmware, almanac, and ephemeris data, enabling fully autonomous operation without external memory components - reducing BOM cost and PCB area.
Can STA8089FGATR operate without an external crystal?
No. STA8089FGATR requires a 32.768 kHz crystal connected to XTAL_IN/XTAL_OUT pins for RTC functionality and low-power timing during standby. The device does not include an internal RC oscillator for this function; omission prevents RTC operation and impacts cold-start performance.
Is STA8089FGATR pin-compatible with earlier ST GNSS receivers?
Yes. STA8089FGATR is pin-to-pin compatible with STA8088FG, allowing direct replacement in existing designs. This compatibility preserves layout, power delivery, and signal routing while upgrading to improved sensitivity (-162 dBm), faster TTFF, and expanded BeiDou/QZSS support.
