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 corebased STM32F746NGH6 microcontroller. This microcontroller features four I2Cs, six SPIs
with three multiplexed simplex I2S, 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 KB SRAM and 1 MB 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 to evaluate almost all peripherals
(USB OTG HS, USB OTG FS, Ethernet 10/100Mb, 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 develop your own applications. Arduino Uno V3 connectors make it possible
to easily connect extension shields or a daughterboard for your specific application. The
integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and programmer for the
STM32 MCU.
The STM32F746G-DISCO board comes with the STM32 comprehensive software HAL
library together with various packaged software examples, as well as a direct access to
mbed online resources at http://mbed.org.

Product marking
Product marking
Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are not ready
to be used as reference design or in production. Any consequences deriving from such
usage will not be at ST charge. In no event, ST will be liable for any customer usage of
these engineering sample tools as reference design or in production.

Hardware layout and configuration
STM32F746G-DISCO discovery board is designed around the STM32F746NGH6 (216-pin
TFBGA package). The hardware block diagram (see Figure 3) illustrates the connection
between STM32F746NGH6 and peripherals (SDRAM, Quad-SPI Flash memory, camera
module, color LCD, USB OTG connectors, USART, Ethernet, Audio, SPDIFRX, MicroSD
card, Arduino Uno shields and embedded ST-LINK) and Figure 3 will help to locate these
features on the actual discovery board.

USB power management request for more than 100mA power on USB
These features are no more supported on ST-LINK/V2-1:
•

•
Application voltage lower than 3 V
For all general information concerning debugging and programming features common
between V2 and V2-1 please refer to ST-LINK/V2 user manual (UM1075).
6.1.1
Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows XP, 7 and 8, can be
found at www.st.com.
In case the STM32F746G-DISCO discovery board is connected to the PC before the driver
is installed, some STM32F746G-DISCO interfaces may be declared as “unknown” in the PC
device manager. In this case the user must install the driver files, and update the driver of
the connected device from the device manager.
Note:
Prefer using the “USB Composite Device” handle for a full recovery.

ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the
USB port. As the firmware may evolve during the life time of the ST-LINK/V2-1 product (for
example new functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the STM32F746G-DISCO board
and periodically, in order to stay up-to-date with the latest firmware version.
6.2
Power supply
STM32F746G-DISCO discovery board is designed to be powered by 5V DC power supply.
It’s possible to configure the discovery board to use any of the following five sources for the
power supply.
•
5V DC power adapter connected to JP2 (external power supply on silkscreen of JP1
(5V ext)). In this case, the STM32F746G-DISCO discovery board must be powered by
a power supply unit or by an auxiliary equipment complying with standard
EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with
limited power capability.
Figure 6. JP1 (5V ext) from JP2 (5V)
•
7-12V DC power from CN6 pin named Vin on silkscreen, the extension connectors for
Arduino UNO shields or daughterboard (external power source on silkscreen of JP1
(5V ext)).

UM1907
Hardware layout and configuration
•
5V DC power with limitation from CN14, the USB type mini-B connector of ST-LINK/V21 (USB 5V power source on silkscreen of JP1 (5V link)). It is the default setting. If the
USB enumeration succeeds (as explained below), the ST-LINK 5V link power is
enabled, by asserting the PWR_ENn signal. This pin is connected to a power switch
(ST890), which powers the board. This power switch features also a current limitation
to protect the PC in case of a short-circuit on board (more than 600mA).
STM32F746G-DISCO discovery board can be powered from ST-LINK USB connector CN14
(5V link), but only ST-LINK circuit has the power before USB enumeration, because the host
PC only provides 100mA to the board at that time. During the USB enumeration,
STM32F746G-DISCO board asks for the 500mA power to the host PC. If the host is able to
provide the required power, the enumeration finishes by a “SetConfiguration” command and
then, the power transistor U8 (ST890) is switched ON, the red LED LD2 is turned ON, thus
STM32F746G-DISCO board can consume maximum 500mA current, but no more. If the
host is not able to provide the requested current, the enumeration fails. Therefore the ST890
(U8) remains OFF and the MCU part including the extension board won’t be powered. As a
consequence the red LED LD2 remains turned OFF. In this case it is mandatory to use an
external power supply.
Figure 8. JP1 (5V link)
Note:
In case the board is powered by an USB charger, there is no USB enumeration, so the led
LD2 remains set to OFF permanently and the board is not powered. Only in this specific
case, the resistor R109 needs to be soldered, to allow the board to be powered anyway.
The LED LD2 is lit when the STM32F746G-DISCO discovery board is powered by the 5V
correctly.
Caution:
Do not connect PC to ST-LINK (CN14) when R109 is soldered. PC may be damaged or the
board not powered correctly.

Programing/debugging when the power supply is not from
ST-LINK (5V link)
It is mandatory to power the board first using JP1 (5V ext) or (usb_hs) or (usb_fs), then
connecting the USB cable to the PC. Proceeding this way ensures that the enumeration
succeeds thanks to the external power source.
The following power sequence procedure must be respected:
1.
Connect the jumper JP1 on (5V ext) or (usb_hs) or (usb_fs)
2.
Connect the external power source to JP2 or CN6 or CN12 or CN13
3.
Check the red LED LD2 is turned ON
4.
Connect the PC to USB connector CN14
If this order is not respected, the board may be powered by VBUS first from ST-LINK, and
the following risks may be encountered:
14/49
DocID027942 Rev 2
UM1907
6.4
Hardware layout and configuration
1.
If more than 500mA current is needed by the board, the PC may be damaged or
current can be limited by PC. As a consequence the board is not powered correctly.
2.
500mA will be requested at the enumeration, so there is a risk that the request is
rejected and enumeration does not succeed if PC can’t provide such current.

1. By default OTG_FS_VBUS is driven by software and not by the alternate function of the STM32F746NGH6
(R64 = ON, R63 = OFF, R58 = ON and PA9 = VCP_TX (Virtual Com Port) and PJ12 = OTG_FS_VBUS).
To use the alternate function OTG_FS_VBUS of the STM32F746NGH6, it's needed to have: R64 = OFF,
R63 = ON, R58 = OFF. In that configuration, VCP_TX is no longer available and PA9 = OTG_FS_VBUS,
PJ12 = not connected.
