Product details

Overview

STM32H747I-DISCO from STMicroelectronics is a full-featured Discovery kit built around the dual-core STM32H747XIH6 microcontroller (Arm® Cortex®-M7 @ 480 MHz + Cortex®-M4 @ 240 MHz), featuring 2 Mbytes of Flash, 1 Mbyte of RAM, 4" MIPI DSI® LCD with capacitive touch, Ethernet 10/100 Mbit/s, USB OTG HS, SAI audio codec, and on-board STLINK-V3E debugger. It serves as a complete evaluation and development platform for high-performance embedded applications requiring concurrent real-time and application processing.

For engineers reviewing the STM32H747I-DISCO datasheet, STM32H747I-DISCO pinout, STM32H747I-DISCO application, or STM32H747I-DISCO equivalent, this board enables rapid prototyping of dual-core MCU systems with integrated display, audio, networking, and expansion interfaces - including ARDUINO® Uno V3, Pmod™, STMod+, and camera connectors - under Windows®, Linux®, or macOS® toolchains.

Technical Context

The STM32H747I-DISCO implements a heterogeneous dual-core architecture where the Cortex-M7 core handles high-throughput tasks (e.g., graphics rendering, protocol stacks) while the Cortex-M4 manages real-time control (e.g., motor control, sensor fusion). Memory subsystem includes 256-Mbit SDRAM and dual 512-Mbit Quad-SPI NOR flash for XIP and firmware redundancy.

Hardware peripherals are fully exposed via standardized headers: MIPI DSI® drives the 4" LCD; SAI interfaces with stereo headset jack and external speakers; MEMS microphones feed audio preprocessing; Ethernet PHY complies with IEEE-802.3-2002; and STLINK-V3E provides mass storage, Virtual COM port, and debug over a single USB Micro-AB connection.

Key Specifications

Parameter	Value and Actual Design Meaning
Core Architecture	Dual-core: Arm Cortex-M7 @ 480 MHz + Cortex-M4 @ 240 MHz - enables asymmetric multiprocessing with independent clock domains and memory spaces.
Memory	2 Mbytes Flash + 1 Mbyte RAM + 256-Mbit SDRAM + 2 × 512-Mbit Quad-SPI NOR - supports boot from flash, runtime code execution in RAM, and external memory-mapped graphics/audio buffers.
Display Interface	MIPI DSI® (2-lane) driving 4" capacitive touch LCD - delivers up to 16.7M colors at 800×480 resolution with hardware-accelerated layer composition.
Connectivity	Ethernet 10/100 Mbit/s (IEEE-802.3-2002 compliant), USB OTG HS, SPDIF RCA input, microSD™ slot - enables wired network stack validation, host/peripheral USB use cases, and digital audio I/O.
Audio Subsystem	SAI audio codec with stereo headset jack (line-in/mic-in), analog microphone input, speaker output, and two MEMS digital microphones - supports full-duplex voice capture and playback without external codecs.
Expansion	ARDUINO® Uno V3, Pmod™ Type-2A/4A, STMod+, and DCMI camera (8-bit) connectors - allows plug-and-play integration of sensors, motor drivers, RF modules, and vision peripherals.
Debug & Programming	On-board STLINK-V3E with USB re-enumeration (mass storage, Virtual COM port, SWD/JTAG) - eliminates need for external debug probes during firmware development and serial logging.

FAQ

What distinguishes STM32H747I-DISCO from STM32H747I-DISC1?

The STM32H747I-DISCO includes a 4" MIPI DSI® LCD module with capacitive touch panel, while STM32H747I-DISC1 is identical in all other respects but omits the display. Both share the same STM32H747XIH6 MCU, STLINK-V3E debugger, Ethernet, USB OTG HS, SAI audio, SDRAM, Quad-SPI flash, and expansion headers. The LCD daughterboard is mounted separately on MB1166.

Does STM32H747I-DISCO support external camera modules?

Yes - it features an 8-bit DCMI (Digital Camera Interface) connector compatible with standard OV-series and similar parallel-output CMOS image sensors. The interface is routed directly to the STM32H747XIH6's DCMI peripheral and supports up to QVGA (320×240) at 30 fps with DMA-accelerated frame capture into SDRAM or internal RAM.

Can STM32H747I-DISCO be powered solely via USB?

Yes - the board accepts power from the USB Micro-AB connector (VBUS), which powers both the STLINK-V3E debugger and the target MCU subsystem. It also supports flexible alternative sources: ST-LINK USB VBUS, external 5 V or 3.3 V supplies via dedicated test points, or regulated input through the STMod+ expansion rail - enabling standalone operation without host PC dependency.

Which IDEs and software tools are officially supported?

STMicroelectronics officially supports IAR Embedded Workbench® (Windows only), Keil MDK-ARM (Windows only), and STM32CubeIDE (cross-platform: Windows, Linux®, macOS®). The STM32CubeH7 firmware package provides HAL/LL drivers, middleware (USB Device/Host, FATFS, FreeRTOS), and over 100 validated examples covering all major peripherals including dual-core interprocessor communication (IPC) and cache coherency management.
