Overview

The STM32F446RE is a high-performance microcontroller powered by an ARM Cortex-M4 core with a Floating Point Unit (FPU), running at up to 180 MHz. It bridges the gap between the STM32F4 series and higher-end processors by offering advanced peripherals for complex signal processing and motor control.

Why Choose This Part

This MCU provides a rich peripheral set including 512 KB of Flash memory and a specialized architecture that reduces CPU load during intensive I/O operations. The inclusion of an adaptive real-time (ART) accelerator allows for zero-wait-state execution from Flash, maximizing the 180 MHz clock performance.

Applications

Field-Oriented Control (FOC)

Utilizes advanced timers and fast ADCs to implement precise brushless DC (BLDC) and stepper motor control algorithms.

Digital Audio Processing

Leverages dedicated audio PLLs and I2S/SAI interfaces for high-fidelity audio streaming and synchronization.

Sensor Fusion

Processes data from multiple IMUs and environmental sensors using the DSP instructions and FPU for robotics and navigation.

Industrial Gateway

Manages data aggregation and communication using USB and multiple serial interfaces in factory automation environments.
