Product details
Overview
STA8089FGADTR 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, ARM946 MCU (196 MHz), 256 KB SRAM, 16 Mbit in-package SQI Flash, RTC, dual CAN, USB 2.0 full-speed PHY, and dual 10-bit ADCs. Designed for in-dash navigation and OEM telematics, it achieves –162 dBm indoor tracking sensitivity and <1 s hot-start TTFF.
For engineers reviewing the STA8089FGADTR datasheet, STA8089FGADTR pinout, STA8089FGADTR application, or STA8089FGADTR equivalent, key selection criteria include multi-constellation timing accuracy under urban canopy, embedded Flash eliminating external memory, AEC-Q100 qualification with zero-defect production flow, and pin-to-pin compatibility with STA8088FG for legacy migration.
Technical Context
The STA8089FGADTR implements a unified G3BB+ baseband processor handling simultaneous acquisition and tracking across five GNSS constellations using dedicated correlator engines and fast-acquisition hardware acceleration. Its RF section integrates LNA, VGA, and mixer stages with on-chip 1.2 V analog supplies (VCC_RF, VCC_PLL, VCC_CHAIN) and supports 10–52 MHz reference clocks for flexible oscillator integration.
The MCU subsystem features ARM946E-S core with 16 KB I-cache, 8 KB D-cache, and switchable 7×16 KB TCM; peripherals include three UARTs (one with BOOT function), I²C master, SSP/SPI, dual CAN 2.0B controllers, USB 2.0 full-speed transceiver, and 10-bit SAR ADC with two input channels - all managed via APB/AHB bridges and clock-gated power domains.

Pinout & Package
STA8089FGADTR is housed in a VFQFPN56 package (7 mm × 7 mm × 1.0 mm, 0.4 mm pitch) with exposed thermal pad. The 56-pin layout separates power domains (VCC_RF, VCC_PLL, VINL, VINB), RF inputs (LNA_IN, XTAL_IN/OUT), digital interfaces (USB_DP/DM, CAN0/1, UARTs), and configurable GPIOs with alternate functions including SPI/SQI, I²C, and timer capture.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC_RF / VCC_PLL / VCC_CHAIN | Analog RF supply pins | Independent 1.2 V regulated supplies for RF chain, PLL, and mixer - prevent noise coupling between analog blocks |
| LNA_IN | RF front-end input | Direct connection point for active/passive GNSS antenna; accepts –162 dBm signals with integrated LNA gain control |
| XTAL_IN / XTAL_OUT | 32.768 kHz crystal interface | Drives internal RTC oscillator; supports external TCXO for enhanced timing stability in vibration-prone automotive environments |
| USB_DP / USB_DM | USB 2.0 full-speed differential pair | On-chip PHY enables direct connection to USB host without external transceiver - reduces bill-of-materials and ESD protection complexity |
| CAN0_TX / CAN0_RX / CAN1_TX / CAN1_RX | Controller Area Network interfaces | Dual isolated CAN 2.0B controllers support diagnostic communication and sensor fusion with vehicle bus systems |
| ADC_IN1 / ADC_IN2 | Analog-to-digital converter inputs | 10-bit SAR ADC channels for vehicle temperature sensing or battery voltage monitoring - referenced to internal 1.2 V LDO |
| RSTn / STDBYn / WAKEUP | Power management control | Hardware reset, forced standby entry, and wake event trigger - enable ultra-low-power (<10 µA) backup mode with RTC persistence |
Key Features

| In-package 16 Mbit SQI Flash | Eliminates need for external serial NOR/Flash - reduces PCB layer count, signal integrity risk, and system-level qualification effort |
| AEC-Q100 Grade 3 qualification | Validated for –40°C to +85°C operation with zero-defect production flow - satisfies OEM functional safety readiness for non-ASIL telematics modules |
| Pin-to-pin compatibility with STA8088FG | Enables drop-in replacement in existing designs - accelerates platform upgrades without PCB respin or firmware revalidation |
| Integrated USB 2.0 PHY | Full-speed (12 Mbps) transceiver with on-die termination - supports direct PC-based firmware updates and real-time NMEA streaming without level-shifting components |
| ST-DRAW dead reckoning support | Optional TESEO-DRAW firmware enables position hold during GNSS outages (tunnels, garages) using inertial sensor fusion - requires STA8089FGAD variant |

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 | Supports GPS/Galileo/GLONASS/BeiDou but lacks integrated Flash and USB PHY; requires external memory and transceiver. | Targeted at compact portable devices; less suited for automotive due to non-AEC-Q100 qualification and no CAN interfaces. | Select when cost-sensitive consumer-grade design prioritizes small footprint over automotive compliance and integrated peripherals. |
| Qualcomm Snapdragon GNSS Platform (e.g., WCN3680) | SoC-level integration with application processor; GNSS functionality shared with Wi-Fi/BT; no standalone GNSS mode. | Used in Android Auto head units where GNSS is one subsystem among many; not suitable for dedicated telematics or safety-critical logging. | Select only when GNSS is secondary to connectivity and processing; avoid for standalone positioning or deterministic timing use cases. |
Compared with u-blox UBX-M8030-KT and Qualcomm WCN3680, STA8089FGADTR delivers automotive-grade reliability through AEC-Q100 qualification, eliminates external memory and USB transceiver BOM items, and provides dual CAN for seamless vehicle bus integration - making it optimal for OEM-tier telematics and navigation modules requiring long-lifecycle support and zero-defect manufacturing.

FAQ
Does STA8089FGADTR support dead reckoning firmware?
Yes, the STA8089FGADTR variant supports STMicroelectronics' TESEO-DRAW (Dead Reckoning Automotive Way) firmware, enabling position estimation during GNSS outages using inertial sensor inputs. This capability requires external IMU integration and is activated via firmware update - the base STA8089FGA does not include DRAW by default.
What are the power supply requirements for RF and digital domains?
STA8089FGADTR requires four distinct supply rails: VINL = 1.8 V ±5% (main regulator input), VCC_RF/VCC_PLL/VCC_CHAIN = 1.2 V ±10% (analog RF sections), VDD = 1.1–1.32 V (digital core), and VddIO = 1.8 V ±5% or 3.3 V ±10% (I/O ring). Each domain must be decoupled per datasheet layout guidelines to ensure RF noise isolation.
Is external memory required for firmware execution?
No. STA8089FGADTR embeds 16 Mbit SQI Flash and 256 KB SRAM, enabling full GNSS firmware execution-including acquisition, tracking, navigation, and NMEA output-without external memory. This simplifies design, improves security, and reduces system-level qualification scope.
How does STA8089FGADTR achieve AEC-Q100 qualification?
STA8089FGADTR meets AEC-Q100 Grade 3 (–40°C to +85°C) and extends beyond with ST's Automotive Grade program: zero-defect production flow, enhanced wafer-level testing, burn-in screening, and lot traceability. Qualification covers thermal cycling, HTOL, ESD, and mechanical shock per automotive standards.
