Overview

The STM32F746IET6 is a high-performance 32-bit microcontroller based on the ARM Cortex-M7 core operating at up to 216MHz. It features an integrated LCD-TFT controller and Chrom-ART Accelerator for advanced graphics, alongside a wide array of high-speed connectivity interfaces including Ethernet and USB OTG.

Why Choose This Part

The Cortex-M7 core provides superior computational throughput with L1 cache (4KB I-cache, 4KB D-cache) and a hardware floating-point unit. The inclusion of the ART Accelerator and 320KB of SRAM allows for efficient execution of complex software stacks and large buffer management for video or networking.

Applications

Industrial HMI Panels
Leverages the LCD-TFT controller and Chrom-ART Accelerator to drive rich graphical user interfaces on industrial displays.
Networked Control Systems
Utilizes the integrated 10/100 Ethernet MAC and CAN interfaces for real-time industrial communication and gateway tasks.
Digital Audio Processing
Employs the hardware FPU, DSP instructions, and SAI/SPDIF-Rx interfaces for high-fidelity audio mixing and filtering.
Embedded Vision
Connects to CMOS sensors via the Digital Camera Interface (DCMI) for image capture and basic processing at the edge.
