Discovery kit for STM32F7 Series with STM32F746NG MCU
Introduction
The STM32F746G-DISCO discovery board (32F746GDISCOVERY) is a complete
demonstration and development platform for STMicroelectronics ARM
®
Cortex
®
-M7 core-
based STM32F746NGH6 microcontroller. This microcontroller features four I
2
Cs, six SPIs
with three multiplexed simplex I
2
S, 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+16+4-Kbyte SRAM and 1-Mbyte Flash memory, USB HS OTG, USB FS OTG,
Ethernet MAC, FMC interface, Quad-SPI interface, SWD debugging support. This discovery
board offers everything required for users to get started quickly and develop applications
easily.
The full range of hardware features on the board helps users to evaluate almost all
p
eripherals (USB OTG HS, USB OTG FS, 10/100-Mbit Ethernet, microSD
™
card, USART,
SAI Audio DAC stereo with audio jack input and output, MEMS digital microphones,
SDRAM, Quad-SPI Flash memory, 4.3-inch color LCD-TFT with a capacitive multi-touch
panel, SPDIF RCA input, etc.) and to develop their applications. Arduino
™
Uno V3
connectors make it possible to easily connect extension shields or a daughterboard for
users’ specific applications. The integrated ST-LINK/V2-1 provides an embedded in-circuit
debugger and programmer for the STM32.
The STM32F746G-DISCO board comes with the STM32 c
omprehensive software HAL
library together with various packaged software examples, as well as a direct access
to ARM
