Overview

The STM32G474RCT6 is a high-performance mixed-signal microcontroller based on the Arm Cortex-M4F core running at 170MHz. Part of the STM32G4 series, it is specifically designed for power conversion and advanced motor control applications, featuring specialized hardware accelerators like CORDIC and FMAC.

Why Choose This Part

This MCU integrates an impressive analog suite including five 12-bit ADCs with 4-Msps performance and seven 12-bit DACs. The hardware CORDIC and Filter Mathematical Accelerator (FMAC) provide significant speed boosts for DSP-heavy tasks while maintaining lower power consumption than software-only implementations.

Applications

Digital Power Supplies
Utilizes high-resolution timers and fast ADCs for switch-mode power supply (SMPS) control and PFC stages.
Industrial Motor Drives
Implements complex field-oriented control (FOC) using the CORDIC engine to offload trigonometric math from the CPU.
EV Charging Infrastructure
Manages power conversion and communication via integrated CAN-FD and high-speed analog peripherals.
Drones and Robotics
Provides precise BLDC motor control and sensor fusion through its high-speed analog-to-digital converters.
