Overview

The STM32G474RET6 is a high-performance mixed-signal microcontroller powered by an Arm Cortex-M4F core running at 170MHz. Designed for complex power conversion and motor control, it integrates a rich set of advanced analog peripherals including five 12-bit ADCs and seven 12-bit DACs. The device also features dedicated hardware accelerators like the CORDIC and FMAC to offload trigonometric and filter calculations from the CPU.

Why Choose This Part

This MCU stands out for its High-Resolution Timer (HRTIM) capable of 184ps resolution and its massive analog integration which reduces external BOM costs. It includes 128KB of SRAM with hardware parity check and a Routine Booster (CCM SRAM) to maximize execution speed for critical real-time code.

Applications

Digital Power Conversion
Ideal for high-end switch-mode power supplies (SMPS) and inverters using its high-resolution timers and multiple DAC/ADC channels for precise feedback loops.
Field-Oriented Control (FOC)
Utilizes the CORDIC and FMAC accelerators to execute motor control algorithms like vector rotation and PID filtering with minimal CPU overhead.
Industrial Instrumentation
High-density analog integration allows for precise sensor interfacing and signal conditioning in compact form factors.
EV Charging Stations
Supports complex communication and power management tasks in automotive-adjacent infrastructure with dual-bank Flash and CAN FD support.
