STMicroelectronics STM32H743I-EVAL2

Overview

STM32H743I-EVAL2 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 dual Quad-SPI NOR flash support - designed for full-featured embedded application prototyping and peripheral validation.

For engineers reviewing the STM32H743I-EVAL2 datasheet, STM32H743I-EVAL2 pinout, STM32H743I-EVAL2 application, or STM32H743I-EVAL2 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 + crypto acceleration workflows on the H7 series.

Technical Context

The board implements a complete STM32H743XI system architecture: the MCU operates at up to 480 MHz with dual-core capability (Cortex-M7 + optional Cortex-M4 co-processor not present on H743), supports AXI and AHB bus matrix for concurrent memory access, and integrates hardware accelerators for JPEG encoding/decoding and cryptographic operations (AES-128/192/256, SHA-1/224/256, PKA).

It provides native high-speed peripheral routing: USB OTG HS via ULPI PHY, 10/100 Ethernet MAC with external PHY (DP83848), CAN FD transceiver (TJA1057), stereo audio path with SAI-driven DAC and dual I²S-compatible MEMS microphones, and multi-bank external memory interfaces including SDRAM (8 M×32-bit), SRAM (1 M×16-bit), NOR flash (8 M×16-bit), and microSD™ 3.0 (≥8 GB).

FAQ

Does STM32H743I-EVAL2 include the STM32H743XIH6 MCU pre-soldered and functional?

Yes. The board integrates a fully populated STM32H743XIH6 MCU in TFBGA240+25 package, verified operational out-of-box with preloaded demonstration firmware. All core peripherals - including SDRAM, LCD, Ethernet PHY, and USB OTG - are electrically connected and validated per UM2198 user manual revision B.

What debug capabilities does the on-board STLINK-V3E provide?

The STLINK-V3E supports SWD and JTAG debugging, ETM trace via external probe header, virtual COM port, and mass storage programming mode. It enables full firmware download, real-time variable monitoring, and low-level register inspection without requiring additional hardware - compatible with STM32CubeIDE, IAR EWARM, and Keil MDK-ARM.

Can STM32H743I-EVAL2 run cryptographic workloads using hardware accelerators?

Yes. The STM32H743XIH6 MCU includes dedicated hardware accelerators for AES-128/192/256 encryption/decryption, SHA-1/224/256 hashing, and public-key acceleration (PKA). These are accessible via STM32CubeH7 HAL drivers and demonstrated in the STM32Cube MCU Package examples for secure boot and TLS offload.

Is the 5.7" LCD touchscreen compatible with standard GUI frameworks like TouchGFX or emWin?

Yes. The display uses a standard RGB interface with integrated XPT2046 resistive touch controller, fully supported by STM32CubeH7 middleware. TouchGFX v4.20+ and emWin v6.30+ include validated porting layers and example projects targeting this exact board configuration and resolution.
