Overview

The STM32G473MET6 is a high-performance mixed-signal microcontroller based on the Arm Cortex-M4 core running at 170MHz. It features specialized hardware accelerators including a CORDIC for trigonometric functions and a Filter Mathematical Accelerator (FMAC) to optimize digital signal processing and control loop execution.

Why Choose This Part

This MCU excels in control applications by combining a 170MHz FPU-enabled core with a rich set of analog peripherals, including 41 ADC channels and integrated op-amps. The hardware acceleration for math functions significantly reduces CPU load during complex PID or FOC algorithm execution.

Applications

Digital Power Conversion
Utilizes the high-resolution timers and integrated analog peripherals for switch-mode power supply (SMPS) and inverter control.
Brushless DC (BLDC) Motor Drives
Leverages the CORDIC engine for fast vector calculations and five 12-bit ADCs for precise current and position sensing.
Industrial Instrumentation
Integrates seven 12-bit DACs and multiple operational amplifiers for high-precision signal conditioning without external analog components.
Electronic Speed Controllers
High-frequency operation and specialized PWM timers provide the low-latency response required for drone and robotics propulsion.
