Evaluation board with STM32F746NG MCU

Introduction

The STM32746G-EVAL evaluation board is a complete demonstration and development

platform for STMicroelectronics ARM

Cortex

-M7 core-based STM32F746NGH6

microcontroller. It features four I

C interfaces, six SPIs with three multiplexed simplex I

interfaces, SDMMC, four USARTs, four UARTs, two CANs, three 12-bit ADCs, two 12-bit

DACs, two SAIs, 8 to 14-bit digital camera module interface, internal 320+4-Kbyte SRAM

and 1-Mbyte Flash memory, USB HS OTG and USB FS OTG, Ethernet MAC, FMC

interface, Quad-SPI interface, JTAG debugging support. This evaluation board can be used

as a reference design for user application development but it is not considered as a final

application.

The full range of hardware features on the board helps the user to evaluate all peripherals

(USB OTG HS, USB OTG FS, Ethernet, Motor control, CAN, microSD card, USART, Audio

DAC and ADC, digital microphone, IrDA, RF-EEPROM, SRAM, Nor Flash memory,

SDRAM, Quad-SPI Flash memory, 5.7" TFT LCD with a capacitive touch panel and others)

and to develop his applications. Extension headers make it possible to easily connect a

daughterboard for a specific application.

The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer

for the STM32.
