Overview

The STM32H747XI is a high-performance dual-core microcontroller featuring an Arm Cortex-M7 core running up to 480 MHz and an Arm Cortex-M4 core. This architecture allows for a strict separation between real-time tasks and complex application logic, such as graphical user interfaces or communication stacks. It includes 2 MB of Flash and 1 MB of RAM, along with dedicated hardware acceleration for graphics and JPEG processing.

Why Choose This Part

The dual-core architecture eliminates the need for a separate co-processor by offloading real-time interrupts to the Cortex-M4 while the Cortex-M7 handles heavy computational loads. It features a rich set of high-speed peripherals including MIPI DSI, USB OTG, and dual CAN FD, alongside hardware acceleration for JPEG and 2D graphics that significantly reduces CPU overhead for display tasks.

Applications

High-End Industrial HMI
Leverages the MIPI DSI interface and DMA2D Chrom-Art Accelerator to drive complex graphical interfaces while maintaining real-time control via the M4 core.
Edge AI and Predictive Maintenance
Utilizes the 480 MHz Cortex-M7 for local inference and signal processing of sensor data, with the M4 handling low-latency motor control or sensor acquisition.
Professional Audio Systems
Takes advantage of multiple I2S, SAI, and SPDIFRX interfaces to manage high-fidelity multi-channel audio processing and routing.
Secure Industrial Gateways
Uses the dual-core isolation and integrated Ethernet MAC to separate sensitive network communication from local control tasks.
