STMicroelectronics STM32756G-EVAL2

Overview

STM32756G-EVAL2 from STMicroelectronics is an evaluation board built around the STM32F756NGH6 ARM® Cortex®-M7 microcontroller featuring 1 Mbyte Flash, 320+4 Kbytes RAM, and integrated peripherals including dual CAN 2.0A/B, Ethernet MAC, USB OTG HS/FS, and a 5.7-inch 640×480 TFT LCD with capacitive touch panel. It supports audio via SAI-based stereo DAC and digital microphone, camera interface, and multiple memory options (SDMMC, SDRAM, QuadSPI NOR Flash).

For engineers reviewing the STM32756G-EVAL2 datasheet, STM32756G-EVAL2 pinout, STM32756G-EVAL2 application, or STM32756G-EVAL2 equivalent, this board serves as a complete hardware reference for validating STM32F756NGH6-based designs-especially where high-performance real-time control, multimedia I/O, connectivity (Ethernet/CAN/USB), and human-machine interface (capacitive touchscreen, audio, camera) are required.

Technical Context

The board implements the full peripheral set of the STM32F756NGH6 MCU, including two SAI interfaces driving stereo audio DAC and digital microphone, dual CAN controllers compliant with ISO 11898-1, IEEE 802.3-compliant Ethernet PHY interface, and FMC-controlled external memories (8Mx32-bit SDRAM, 8Mx16-bit NOR Flash). The integrated ST-LINK/V2-1 provides JTAG/SWD debugging and programming without external tools.

It supports simultaneous high-speed connectivity (USB OTG HS + Ethernet + CAN), real-time multimedia processing (via Cortex-M7's DSP extensions and hardware crypto acceleration), and HMI development using the 5.7" capacitive touchscreen and joystick. All six USB power options-including ST-LINK/V2-1, USB HS/FS connectors, power jack, and daughterboard-enable flexible lab and prototyping power configuration.

FAQ

Does STM32756G-EVAL2 include an on-board debugger?

Yes. It integrates ST-LINK/V2-1, providing full SWD/JTAG debugging, flash programming, and virtual COM port functionality without requiring external debug probes. Firmware updates and real-time tracing (including ETM) are supported directly through the USB Micro-B connector used for ST-LINK communication.

What display resolution and interface does the board support?

The board features a 5.7-inch TFT LCD with native 640×480 resolution, driven by the STM32F756NGH6's LTDC controller and FMC interface. Capacitive touch is handled via an I²C-connected controller, and the display supports RGB565 pixel format with hardware layer blending and alpha blending.

Can the STM32756G-EVAL2 be used for Ethernet and CAN coexistence testing?

Yes. The board provides independent, electrically isolated hardware paths for both IEEE 802.3-compliant Ethernet (RMII interface with external PHY) and dual CAN 2.0A/B controllers (with transceivers and DB9 connectors). Both interfaces operate concurrently under RTOS or bare-metal scheduling without resource conflict.

Is the camera interface compatible with common OV or MT9V034 modules?

Yes. The DCMI interface conforms to standard 8-/10-/12-/14-bit parallel DVP timing and supports common CMOS sensors including OV7670, OV2640, and MT9V034. The board provides dedicated 24-pin DVP connector with VSYNC, HREF, PCLK, and 8/10/12-bit data lines routed to GPIO pins mapped for DCMI alternate functions.
