Product details

Overview

STM32H745I-DISCO from STMicroelectronics is a Discovery kit development board centered on the STM32H745XIH6 microcontroller - dual-core Arm® Cortex®-M7/M4, 2 Mbyte Flash, 1 Mbyte RAM in TFBGA240+25 package - featuring integrated 4.3" RGB LCD with touch panel, Ethernet 10/100 Mbps with PoE, USB OTG FS, SAI audio codec, MEMS digital microphone, eMMC, SDRAM, and dual CAN FD interfaces.

For engineers reviewing the STM32H745I-DISCO datasheet, STM32H745I-DISCO pinout, STM32H745I-DISCO application, or STM32H745I-DISCO equivalent, this board serves as a production-ready reference platform for evaluating high-performance real-time embedded systems requiring multi-core coordination, rich multimedia I/O, deterministic Ethernet, and secure boot-capable MCU firmware development.

Technical Context

The board implements a complete dual-core evaluation environment where the Cortex-M7 core runs at up to 480 MHz and the Cortex-M4 at up to 240 MHz, sharing memory via tightly coupled AXI bus and L2 cache coherency. It supports concurrent execution of real-time control (M4) and high-throughput processing (M7), with hardware-accelerated cryptography (AES, HASH, PKA) and secure boot ROM.

Hardware peripherals include IEEE 802.3-compliant Ethernet PHY with PoE power extraction, full-speed USB OTG with device/host capability, stereo SAI-driven audio path with headset jack and external speaker header, and dual CAN FD controllers compliant with ISO 11898-1:2015.

FAQ

What is the target microcontroller on the STM32H745I-DISCO board?

The board integrates the STM32H745XIH6 - a dual-core Arm Cortex-M7/M4 microcontroller with 2 Mbyte Flash, 1 Mbyte RAM, and TFBGA240+25 packaging. It is factory-programmed with demonstration firmware and fully supported by STM32CubeH7 software packages, HAL drivers, and middleware stacks including FreeRTOS and USB Device Class libraries.

Does the board support debugging and programming out of the box?

Yes - it includes an on-board ST-LINK V3E debugger/programmer with USB re-enumeration supporting three modes simultaneously: mass storage (for drag-and-drop firmware updates), Virtual COM port (for serial logging), and SWD/JTAG debug port (for breakpoints, register inspection, and real-time tracing via IDEs like STM32CubeIDE, IAR EWARM, or Keil MDK).

Can the STM32H745I-DISCO be used for Ethernet-based industrial protocols?

Yes - the board implements a compliant IEEE 802.3-2002 10/100 Mbps Ethernet interface with external PHY and PoE power extraction. It supports TCP/IP stacks (LwIP), real-time protocols (EtherCAT slave stack via X-CUBE-ETHERNET), and time-sensitive networking features when combined with HAL Ethernet drivers and STM32H7-specific DMA optimizations for zero-copy packet handling.

Is the LCD display touchscreen-enabled and what interface does it use?

Yes - the 4.3" display uses an RGB parallel interface (24-bit color, 480×272 resolution) with integrated capacitive multi-touch controller. The touch panel connects via dedicated I²C interface to the MCU, and touch data is accessible through STM32CubeH7's BSP layer (BSP_TS_ITConfig, BSP_TS_GetXY) with calibrated coordinate mapping and gesture support.
