Overview

The STM32F746NGH6 is a high-performance ARM Cortex-M7 microcontroller operating at up to 216 MHz. It features a rich set of peripherals including a dedicated LCD-TFT controller and Chrome-ART Accelerator for advanced graphical user interfaces. With 1MB of Flash and 320KB of RAM, it is designed for demanding applications requiring high-speed processing and sophisticated connectivity.

Why Choose This Part

The inclusion of L1-cache (4KB data, 4KB instruction) and the ART Accelerator minimizes wait states when executing from Flash or external memory. Its TFBGA216 package provides a high I/O count, supporting a wide range of simultaneous interfaces including Quad-SPI and a flexible external memory controller.

Applications

Industrial HMI Panels
Utilizes the integrated LCD-TFT controller and Chrom-ART Accelerator to drive high-resolution graphical interfaces with minimal CPU overhead.
Smart Home Hubs
Manages complex networking stacks and local data processing using the high-clock-speed Cortex-M7 core and L1-cache.
Digital Audio Processing
Leverages DSP instructions and a floating-point unit (FPU) for real-time filtering, equalization, and audio synthesis.
Edge AI Inference
Provides sufficient computational power and memory bandwidth for running localized machine learning models at the edge.
