STMicroelectronics STM32746G-EVAL2

Overview

STM32746G-EVAL2 from STMicroelectronics is an evaluation board built around the STM32F746NGH6 ARM® Cortex®-M7 microcontroller (1 MB Flash, 320+4 KB RAM), featuring a 5.7" 640×480 TFT LCD with capacitive touch, dual USB OTG (HS/FS), Ethernet MAC, SAI audio DAC, stereo digital microphone, microSD slot, SDRAM/SRAM/NOR/QuadSPI Flash, camera interface, CAN 2.0A/B, and integrated ST-LINK/V2-1 debugger.

For engineers reviewing the STM32746G-EVAL2 datasheet, STM32746G-EVAL2 pinout, STM32746G-EVAL2 application, or STM32746G-EVAL2 equivalent, this board serves as a complete hardware reference for evaluating STM32F746NG peripheral integration-including USB HS/FS, Ethernet, touch LCD, audio subsystems, motor control, and real-time connectivity in embedded industrial and multimedia applications.

Technical Context

The board implements the full peripheral suite of the STM32F746NGH6 MCU, including dual USB OTG controllers (one HS with PHY, one FS), IEEE-802.3-compliant Ethernet MAC with external PHY support, two SAI interfaces for audio streaming, three 12-bit ADCs and two 12-bit DACs, and an 8–14-bit parallel camera interface. It supports simultaneous high-bandwidth peripherals via dedicated bus matrix arbitration.

Power architecture provides six independent 5 V supply options (power jack, ST-LINK/V2-1 USB, USB HS/FS connectors, daughterboard header, and on-board regulator), enabling flexible power-source validation. Debug infrastructure includes JTAG/SWD and ETM trace via embedded ST-LINK/V2-1, eliminating need for external debug probes.

FAQ

Does STM32746G-EVAL2 include the STM32F746NGH6 MCU pre-soldered?

Yes. The board integrates the STM32F746NGH6 microcontroller in LQFP208 package with 1 MB Flash and 320+4 KB SRAM pre-mounted and fully functional. All peripherals-including USB OTG HS/FS, Ethernet MAC, SAI, ADC/DAC, and camera interface-are routed and validated per ST's reference design.

Can STM32746G-EVAL2 be used for production deployment?

No. STM32746G-EVAL2 is explicitly designated as an evaluation and development platform-not a certified production-ready board. It lacks industrial-grade thermal management, conformal coating, and EMI/EMC certification required for end-product deployment.

What debugging interfaces does STM32746G-EVAL2 support?

The board features embedded ST-LINK/V2-1 supporting SWD and JTAG protocols, plus ETM trace capability. No external debugger is needed. Firmware can be programmed and debugged directly via the Micro-B USB port connected to the ST-LINK/V2-1 interface.

Is the 5.7" TFT LCD compatible with standard GUI frameworks?

Yes. The display uses an ILI9341-compatible driver with 16-bit RGB interface and capacitive touch controller (STMPE811). ST provides official HAL drivers and TouchGFX examples targeting this exact configuration in STM32CubeF7 firmware packages.
