The STA8090WG from STMicroelectronics is a compact, all-in-one GNSS receiver. It provides accurate navigation and positioning using signals from GPS, Galileo, GLONASS, BeiDou, and QZSS satellites.
It includes a built-in RF front end, a low-noise amplifier, and efficient power management. This System-on-Chip delivers fast, reliable performance even in small, space-limited designs.
Part of ST’s Teseo III series, the STA8090WG uses a powerful ARM946 processor with built-in memory and flexible connectivity. It’s ideal for embedded systems, in-dash navigation, and telematics devices. With ultra-low power use and high sensitivity (-162 dBm), it maintains accurate positioning indoors and in challenging environments.
Let’s take a closer look at what makes this GNSS receiver a reliable choice for modern navigation devices.
Multi-Constellation GNSS Support
Receives and processes signals from GPS, Galileo, GLONASS, BeiDou, and QZSS for high-accuracy positioning worldwide.
Fully Integrated Receiver
Combines the RF front end, low-noise amplifier (LNA), and baseband processor on a single die to simplify design and reduce external components.
High-Performance ARM946 Processor
Runs up to 196 MHz with 256 KB embedded SRAM and external SQI Flash interface for firmware storage and flexibility.
Fast Time-to-First-Fix (TTFF)
Delivers < 1 s hot start and 30 s cold start for quick signal acquisition and rapid navigation startup.
Advanced Power Management
Built-in switching regulator and multiple low-power modes optimise performance for portable or battery-powered devices.
Wide Voltage and Temperature Range
Operates from 1.6 V to 4.3 V and –40 °C to +85 °C, ensuring reliability across harsh environments.
Comprehensive Interface Options
Supports USB 2.0, UART, I²C, SPI, and CAN (BD version) for flexible system integration.
Compact WLCSP-77 Package (3.86 × 3.84 mm)
Ideal for space-constrained embedded systems, offering performance and precision in a minimal footprint.
The STA8090WG is ideal for compact and power-sensitive embedded systems requiring robust positioning:
Automotive navigation and telematics
Industrial asset tracking and fleet management
Smart cameras and wearable devices
Drones, robotics, and unmanned systems
Portable data loggers and handheld computers
Sports and outdoor navigation equipment
At Component Sense, we specialise in the fast, reliable, and sustainable supply of brand-new, fully traceable, and counterfeit-free electronic components like the STA8090WG.
Here’s why global procurement teams trust us:
We hold over $1 billion worth of excess and obsolete (E&O) inventory. Our frequently updated stock means you can fulfil BOMs quickly and avoid production delays.
Every part we supply is new, unused, and fully traceable back to the original manufacturer. We only source from trusted tier-one OEM and EMS partners with rigorous quality controls.
Our inspection process, developed in collaboration with leading Scottish universities, ensures every part meets full form, fit, and function standards. All stock comes with a 12-month warranty for peace of mind.
We extend the lifecycle of components by redistributing E&O stock, helping to reduce global e-waste. Plus, we plant two trees for every order, offsetting carbon impact for both buyers and sellers.
Since 2001, we’ve delivered fast quotes (under 1 hour), and a 95% on-time delivery rate to keep your supply chain running smoothly.
When sourcing the STA8090WG, choose Component Sense for authenticity, speed, and sustainability.
