Overview

The STM32G474MET3 is a high-performance mixed-signal microcontroller based on the Arm Cortex-M4 core operating at 170MHz. Part of the STM32G4 'Hi-resolution' series, it features specialized hardware accelerators like CORDIC and FMAC alongside rich analog integration including 512KB Flash and 128KB RAM.

Why Choose This Part

This MCU offers a unique combination of 170MHz throughput and hardware accelerators (CORDIC for math, FMAC for filtering) that offload the CPU. Its extensive analog suite, including 41 ADC channels and multiple DACs, significantly reduces BOM cost and PCB footprint in complex control systems.

Applications

Digital Power Conversion
Utilizes the high-resolution timers and integrated analog comparators for switched-mode power supplies (SMPS) and digital PFC.
Advanced Motor Control
Leverages the CORDIC engine for trigonometric calculations and three fast 12-bit ADCs to manage complex field-oriented control (FOC) algorithms.
Industrial Instrumentation
Integrates 7 DAC channels and 41 ADC channels with hardware oversampling for high-precision sensor interfacing without external converters.
