Product details
Overview
STA8089GA 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, and sub-1-second hot-start TTFF. It integrates RF front-end, ARM946 MCU (196 MHz), 256 KB SRAM, dual CAN, USB 2.0 full-speed PHY, and RTC - deployed in OEM telematics and in-dash navigation systems.
For engineers reviewing the STA8089GA datasheet, STA8089GA pinout, STA8089GA application, or STA8089GA equivalent, key selection criteria include multi-constellation timing accuracy under urban multipath, backup power domain behavior (VINB 1.6–4.3 V), dual-CAN bus integration for vehicle network co-location, and VFQFPN56 package thermal performance at -40/+85°C.
Technical Context
The STA8089GA implements a dual-path RF front-end with dedicated signal paths for GALGPS (1575.42 MHz → 4.092 MHz) and GNSCOM (GLONASS/BeiDou, 1601.718/1561.098 MHz → 8.57/10.23 MHz), each feeding a 3-bit sign-magnitude ADC and programmable VGA. Its G3BB+ baseband processor performs simultaneous acquisition and tracking across up to four constellations, with GLONASS and BeiDou operating in mutual exclusion mode.
The embedded ARM946E-S core runs at up to 196 MHz, supported by 16 KB I-cache, 8 KB D-cache, and switchable 7×16 KB TCM; peripherals include two UARTs (one with BOOT0 function), I²C master/slave, SQI Flash interface, 10-bit dual-channel SARADC, and dual CAN controllers compliant with ISO 11898-1.

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 | 22 nm process, 33 tracking channels, no integrated MCU; requires external host processor | Lacks ARM946 core and embedded firmware - needs host-side NMEA parsing and navigation stack | Select when system already includes capable application processor and minimal BOM footprint is prioritized over integration |
| Qualcomm WGR7640 | Supports GPS/Galileo/GLONASS only; no BeiDou/QZSS; integrated LTE modem | Combines GNSS + cellular in single chip - suited for standalone telematics but lacks dual-CAN and automotive temp range | Select for connected devices requiring integrated comms, but avoid where AEC-Q100 compliance or CAN bus interfacing is mandatory |
Compared with u-blox UBX-M8030-KT and Qualcomm WGR7640, STA8089GA uniquely combines AEC-Q100 qualification, dual CAN, embedded ARM946 navigation engine, and full five-constellation support - making it the only option for safety-critical automotive head units requiring self-contained positioning and vehicle bus integration.

FAQ
Is STA8089GA pin-compatible with STA8088GA?
Yes, STA8089GA is pin-to-pin compatible with STA8088GA, sharing identical VFQFPN56 footprint, power pin mapping, and peripheral signal assignments. This enables direct replacement in existing designs without PCB revision, though firmware updates may be required to leverage new features like enhanced QZSS support and improved cold-start TTFF.
Does STA8089GA support dead reckoning (DR) functionality?
No, DR functionality via TESEO-DRAW firmware is exclusive to the STA8089GAD variant. STA8089GA lacks the required internal sensor fusion logic and GPIO configuration for inertial measurement unit (IMU) interfacing. For dead reckoning, ST recommends pairing STA8089GA with external IMU sensors and custom host-side DR algorithms.
What are the voltage requirements for the backup domain (VINB)?
VINB accepts 1.6 V to 4.3 V, powering the backup LDO (VOB = 1.0 V), RTC, and BKRAM. It must remain active during main supply (VINL) dropout to preserve time and position context. Typical implementation uses a supercapacitor or small Li-ion cell charged from VINL via diode or dedicated charger IC.
Can STA8089GA operate without an external crystal?
No - STA8089GA requires a 32.768 kHz crystal connected to RTC_XTI/RTC_XTO for real-time clock operation and a 10–52 MHz reference clock (e.g., TCXO) on XTAL_IN/XTAL_OUT for RF synthesizer and MCU clock generation. The device does not support internal RC oscillators for timing-critical functions.
