STM32G474QET6
Overview
The STM32G474QET6 is a high-performance mixed-signal microcontroller powered by the Arm Cortex-M4 core running at 170MHz. It is specifically designed for digital power conversion and motor control applications, featuring advanced analog peripherals and mathematical hardware accelerators like CORDIC and FMAC.
Why Choose This Part
This MCU offers a unique combination of 170MHz processing speed with dedicated hardware accelerators (CORDIC and FMAC) that offload complex math from the CPU. It integrates a massive 42-channel ADC and 7-channel DAC system, significantly reducing the need for external analog components in multi-phase power systems.
Applications
Key Specifications
Getting Started
Developers should use the STM32CubeIDE ecosystem and the STM32CubeG4 software package for driver configuration. For hardware evaluation, the NUCLEO-G474RE board provides a compatible environment, while the ST-LINK/V3 debugger is recommended for high-speed programming and tracing.
Dev Boards
Development boards and breakout modules featuring the STM32G474QET6 or compatible chips — ready to use for prototyping.
