Discovery kit with STM32H747XI MCU
Introduction
The STM32H747I-DISCO Discovery kit is a complete demonstration and development
platform for the STMicroelectronics Arm
®
Cortex
®
-M7 and -M4 dual-core-based
STM32H747XIH6 microcontroller with four I
2
C, six SPIs with two multiplexed full-duplex I
2
S
interfaces, SDIO3.0, SDIO2.0, four USARTs, four UARTs, two FD-CANs, three 16-bit ADCs,
two 12-bit DACs, four SAIs, USB HS OTG and USB FS OTG, Ethernet MAC, FMC interface,
MIPI DSI
SM
host controller, Quad-SPI interface, and JTAG and ETM debugging support.
The STM32H747I-DISCO Discovery kit, shown in Figure 1 and Figure 2, is used as a
reference design for user application development before porting to the final product.
STM32H747I-DISC1, presented in Figure 3, is the subset of STM32H747I-DISCO without
the LCD display module.
The full range of hardware features available on the board helps users improve application
development by an evaluation of all the peripherals (USB OTG2 HS, Ethernet, microSD™
card, SAI Audio DAC stereo with audio jack input and output, MEMS digital microphone,
SDRAM, Quad-SPI Flash, DCMI connector, MIPI DSI
SM
interface, and others). Arduino™
Uno V3 and Pmod™/STMod+ connectors provide easy connection to extension shields or
daughterboards for specific applications.
An STLINK-V3E is integrated into the board, as the embedded in-circuit debugger and
programmer for the STM32 MCU and the USB Virtual COM port bridge.
