Product details

Overview

STM32H743I-EVAL from STMicroelectronics is a high-end evaluation board built around the STM32H743XIH6 Arm® Cortex®-M7 microcontroller (2 MB Flash, 1 MB RAM, TFBGA240+25), featuring a 5.7" 640×480 TFT LCD with touch panel, Ethernet (IEEE-802.3-2002), USB OTG HS/FS, CAN FD, SAI audio DAC, MEMS digital microphones, and twin Quad-SPI NOR flash support - used for full-featured embedded application prototyping and peripheral validation.

For engineers reviewing the STM32H743I-EVAL datasheet, STM32H743I-EVAL pinout, STM32H743I-EVAL application, or STM32H743I-EVAL equivalent, this board serves as a production-ready reference platform for evaluating real-time OS deployment, multimedia interface integration, industrial connectivity stacks (Ethernet/CAN FD), and secure boot + cryptographic peripheral bring-up on Cortex-M7.

Technical Context

The board implements a dual-board architecture: main board (MB1246) hosting the STM32H743XIH6 MCU, LCD controller, SDRAM/SRAM/NOR flash, and power management; plus dedicated daughterboards for LCD (MB1063) and microSD™ transceiver (MB1256). All peripherals are directly accessible via standardized expansion connectors.

It integrates an on-board ST-LINK/V2-1 debugger/programmer supporting mass storage, Virtual COM port, and SWD/JTAG debug interfaces - enabling seamless firmware flashing, real-time tracing (ETM), and host-side development without external tools. Power is flexibly supplied via USB VBUS, external DC jack, or ST-LINK USB.

FAQ

Does STM32H743I-EVAL support debugging via SWD or JTAG?

Yes - it features an integrated ST-LINK/V2-1 debugger/programmer accessible through the onboard Micro-AB USB connector, supporting both SWD and JTAG protocols. The interface enumerates as a mass storage device, virtual COM port, and debug port simultaneously, enabling firmware flashing, real-time variable inspection, and ETM trace with compatible IDEs like STM32CubeIDE or IAR Embedded Workbench.

What is the maximum supported microSD™ card capacity and interface version?

The board supports microSD™ cards compliant with SDIO 3.0 specification, with tested operation up to 8 GB and compatibility confirmed with larger capacities (≥32 GB) using FAT32 formatting. The SDIO interface operates in 4-bit mode at up to 50 MHz, delivering sustained read/write throughput suitable for media buffering and firmware over-the-air (FOTA) staging.

Can the STM32H743I-EVAL be used to evaluate cryptographic functions?

No - cryptographic hardware acceleration (AES, HASH, PKA, RNG) is only available on the STM32H753XI variant (used on STM32H753I-EVAL). The STM32H743XIH6 MCU on this board lacks the dedicated crypto processor block; software-based cryptography libraries (e.g., Mbed TLS) can be deployed but without hardware acceleration benefits.

Is the LCD touchscreen resistive or capacitive, and what controller is used?

The 5.7" display uses a 4-wire resistive touch panel controlled by the onboard SSD1963 display driver IC. It supports 640×480 resolution, 24-bit RGB color depth, and direct parallel interface to the STM32H743XIH6 via FSMC, enabling low-latency GUI rendering and touch coordinate acquisition without external bridge ICs.
