Overview

The STM32G474CBT6 is a high-performance 32-bit microcontroller based on the Arm Cortex-M4 core running at 170MHz. Part of the STM32G4 series, it is specifically optimized for mixed-signal applications, featuring advanced analog peripherals and mathematical accelerators like CORDIC and FMAC.

Why Choose This Part

This MCU integrates a CORDIC engine for trigonometric acceleration and a Filter Mathematical Accelerator (FMAC), significantly offloading the CPU in control loop calculations. With 128KB of RAM and dual-bank Flash supporting read-while-write, it offers robust performance for real-time firmware updates and complex execution.

Applications

Digital Power Conversion
Utilizes the High-Resolution Timer (HRTIM) and mathematical accelerators for high-frequency switch-mode power supply control and digital PFC.
Industrial Motor Drives
Ideal for Field Oriented Control (FOC) of brushless DC motors thanks to integrated op-amps, comparators, and dedicated motor control timers.
EV Charging Stations
Provides the necessary analog integration and CAN-FD support for communication and power management in electric vehicle infrastructure.
Drones and Robotics
Combines high-speed processing with low-latency analog sensing for precise motion control in compact form factors.
