STMicroelectronics STM32H747I-EVAL

Overview

STM32H747I-EVAL from STMicroelectronics is a high-end evaluation board built around the dual-core STM32H747XIH6 microcontroller (Cortex-M7 @ 480 MHz + Cortex-M4 @ 240 MHz), featuring 2 Mbytes flash, 1 Mbyte RAM, 4" 480×800 MIPI DSI® TFT LCD with capacitive touch, Ethernet (IEEE-802.3-2002), USB OTG HS/FS, CAN FD, and on-board ST-LINK-V3E debugger. It enables full peripheral validation for industrial HMI, edge AI inference, and real-time control applications.

For engineers reviewing the STM32H747I-EVAL datasheet, STM32H747I-EVAL pinout, STM32H747I-EVAL application, or STM32H747I-EVAL equivalent, this board supports rapid prototyping of dual-core RTOS partitioning, MIPI DSI display integration, cryptographic offload (via companion H757 variant), and multi-interface connectivity testing including Ethernet, CAN FD, and SAI audio subsystems.

Technical Context

The board implements a complete dual-core development environment where the Cortex-M7 handles high-performance tasks (e.g., graphics rendering, DSP) while the Cortex-M4 manages real-time I/O and communication stacks. It integrates MIPI DSI v1.2 for direct display interface, IEEE 802.3-compliant Ethernet PHY with RMII, and dual USB OTG controllers supporting host/device roles with integrated PHYs.

Memory subsystem includes 8 M×32-bit SDRAM, 8 M×16-bit NOR flash, 1-Gbit twin Quad-SPI NOR flash, and SDIO 3.0–compliant microSD™ slot. Audio is supported via SAI-driven DAC, ST-MEMS digital microphones, and analog microphone input through stereo headset jack.

FAQ

What microcontroller is mounted on the STM32H747I-EVAL board?

The board integrates the STM32H747XIH6, a TFBGA240+25 packaged dual-core MCU with Cortex-M7 (480 MHz) and Cortex-M4 (240 MHz), 2 Mbytes of on-chip flash, and 1 Mbyte of RAM. It does not include cryptographic acceleration hardware - that feature is exclusive to the STM32H757XIH6 used on the STM32H757I-EVAL variant.

Does the board support MIPI DSI display output without external components?

Yes - the STM32H747I-EVAL includes a native 4" 480×800 TFT LCD with integrated MIPI DSI® v1.2 interface directly driven by the MCU's DSI host controller. No level-shifter, bridge chip, or timing controller is required for basic display initialization and pixel streaming.

Can the on-board ST-LINK-V3E program external STM32 targets?

Yes - the ST-LINK-V3E firmware supports external target programming via SWD/JTAG through the dedicated debug connector. It enumerates as three separate USB interfaces: mass storage (for drag-and-drop firmware update), virtual COM port (for UART logging), and debug port (for GDB/OpenOCD/IDE integration).

Is CAN FD functionality hardware-verified on this board?

Yes - the board includes a CAN FD transceiver (TJA1057) connected to the MCU's FDCAN peripheral, with routing to an RJ45-style CAN FD compliant connector. Loopback and bus communication have been validated in ST's UM2525 user manual using bundled CubeMX-generated FDCAN examples.
