Product details
Overview
STM32H7S78-DK from STMicroelectronics is a Discovery kit built around the STM32H7S7L8H6H Arm® Cortex®-M7 microcontroller (64 KB Flash, 620 KB SRAM, TFBGA225), featuring a 5" capacitive-touch LCD, dual USB Type-C® (HS/FS with DRP), IEEE 802.3-compliant Ethernet, I2S audio codec, ST-MEMS digital microphone, 1-Gbit Octo-SPI NOR flash, 256-Mbit Hexadeca-SPI PSRAM, Wi-Fi® (802.11 b/g/n), and on-board STLINK-V3EC debugger.
For engineers reviewing the STM32H7S78-DK datasheet, STM32H7S78-DK pinout, STM32H7S78-DK application, or STM32H7S78-DK equivalent, this kit supports rapid evaluation of high-performance MCU peripherals including dual SPI memory interfaces, USB PD-capable Type-C, Ethernet PHY, SAI/I2S audio paths, DCMI camera interface, and multi-protocol connectivity expansion via ARDUINO®, STMod+, Pmod™, and FPC connectors.
Technical Context
The STM32H7S78-DK integrates a full-system development platform-not a component-centered on the STM32H7S7L8H6H MCU with three I²C, six SPI, three USART, two SDMMC, two CAN FD, one Ethernet MAC+PHY, two SAI, two 12-bit ADCs, LCD-TFT controller, FMC, 8–14-bit DCMI, and dual Octo-SPI + one Hexadeca-SPI memory controllers.
Hardware architecture includes four daughterboards (LCD, Wi-Fi®, fan-out, audio MEMS), dedicated power delivery circuitry for USB Type-C® DRP, isolated debug interface via STLINK-V3EC (mass storage, VCP, SWD), and seven standardized expansion interfaces enabling concurrent analog, sensor, wireless, and legacy peripheral integration without signal contention or routing conflict.

FAQ
Does the STM32H7S78-DK support USB Power Delivery negotiation?
Yes. The board implements USB Type-C® DRP with USB 2.0 HS interface capable of full Power Delivery 3.0 negotiation, including source/sink role swap, voltage/current contract selection (5 V/9 V/15 V/20 V), and VCONN power for active cables-verified per USB-IF compliance test plan for Type-C v1.4.
Can the Hexadeca-SPI PSRAM be used as executable code space?
No. The 256-Mbit Hexadeca-SPI PSRAM is configured as external RAM only, accessible via the MCU's flexible memory controller with DMA coherency. It does not support eXecute-In-Place (XIP); code execution remains restricted to internal Flash or Octo-SPI NOR memory mapped in address space.
Is the on-board STLINK-V3EC debugger compatible with third-party IDEs?
Yes. STLINK-V3EC exposes standard CMSIS-DAP-compliant debug interface plus Virtual COM port and mass storage device classes. It works natively with STM32CubeIDE, IAR Embedded Workbench®, Keil MDK-ARM, PlatformIO, and Eclipse-based toolchains without proprietary drivers on Windows, macOS, and Linux.
What camera interfaces are supported by the STM32H7S78-DK?
The board provides a 24-pin FPC connector compliant with DCMI (Digital Camera Interface) standards, supporting 8–14-bit parallel YUV/RGB data streams up to 100 MHz pixel clock. It is electrically and mechanically compatible with ST's OV5640 and OV7670 camera modules and supports JPEG hardware encoding via the MCU's DCMIPP peripheral.
