Introduction
The STM32H7 Nucleo-144 boards based on the MB1364 reference board (NUCLEOH723ZG, NUCLEO-H743ZI (Order code NUCLEO-H743ZI2), and NUCLEO-H753ZI)
provide an affordable and flexible way for users to try out new concepts and build
prototypes, by choosing from the various combinations of performance and power
consumption features provided by the STM32H7 Series microcontroller. The ST Zio
connector, which extends the ARDUINO
provide an easy means of expanding the functionality of the Nucleo open development
platform with a wide choice of specialized shields. The STM32H7 Nucleo-144 boards do not
require any separate probe as they integrate the STLINK-V3 debugger/programmer. The
STM32H7 Nucleo-144 boards come with the comprehensive free software libraries and
examples available with the STM32Cube MCU Package.

• Using the embedded STLINK-V3E
• Using an external debug tool connected to the CN5 MIPI-10 connector.
The STLINK-V3E programming and debugging tool is integrated into the STM32H7
Nucleo-144 board.
The STLINK-V3E makes the STM32H7 Nucleo-144 board Mbed enable.
The embedded STLINK-V3E supports only SWD and VCP for STM32H7 devices. For
information about debugging and programming features, refer to Overview of ST-LINK
derivatives, Technical note (TN1235), which describes in detail all the STLINK/V3 features.
Features supported on STLINK--V3E:
• 5 V power supplied by USB connector (CN1)
• USB 2.0 high-speed-compatible interface
• JTAG/serial wire debugging (SWD) specific features:
– 3 V to 3.6 V application voltage on the JTAG/SWD interface and 5V tolerant inputs
–JTAG
– SWD and serial viewer (SWV) communication
• Direct firmware update feature (DFU) (CN2)
• STDC14 (MIPI10) compatible connector (CN5)
• Status COM LED (LD4) which blinks during communication with the PC
• Fault red LED (LD6) alerting on USB overcurrent request
• 5 V/300 mA output power supply capability (U2) with current limitation and LED
• Green LED ON: 5V enabled (LD5)
6.3.1 Drivers
Before connecting the Nucleo-144 board to a Windows® 7 or Windows® 8 PC via USB, a
driver for STLINK-V3E must be installed (not required for Windows
automatically installed by the toolset supporting ST-LINK. It is also available from the
www.st.com website.
In case the STM32H7 Nucleo-144 board is connected to the PC before installing the driver,
the PC device manager may report some Nucleo interfaces as “Unknown”.
To recover from this situation, after installing the dedicated driver, the association of
“Unknown” USB devices found on the STM32H7 Nucleo-144 board to this dedicated driver,
must be updated in the device manager manually.
Note: It is recommended to proceed using a USB composite device, as shown in Figure 8.

6.3.2 STLINK-V3E firmware upgrade
The STLINK-V3E embeds a firmware upgrade mechanism for an in-situ upgrade through
the USB port. As the firmware may evolve during the lifetime of the STLINK-V3E product
(for example new functionalities, bug fixes, support for new microcontroller families), it is
recommended to keep the STLINK-V3E firmware up to date before starting to use the
STM32H7 Nucleo-144 board. The latest version of this firmware is available from the
www.st.com website.
6.3.3 Using an external debug tool to program and debug the on-boards STM32H7
There are two basic ways to support an external debug tool:
1. Keep the embedded STLINK-V3E running.
Power on the STLINK-V3E at first until the COM LED lights RED. Then connect your
external debug tool through CN5 MIPI-10 debug connector.
2. Set the embedded STLINK-V3E in the high-impedance state:
When you state the jumper JP1 (STLK_RST) ON, the embedded STLINK-V3E is in
RESET state and all GPIOs are in high impedance, then you can connect your external
Debug tool on the debug connector CN5.

6.4 Power supply
The power supply can be provided by five different sources:
• A host PC connected to CN1 through a USB cable (default setting)
• An external 7 V to 12 V power supply connected to CN8 pin 15 or CN11 pin 24
• An external 5 V power supply connected to CN11 pin 6
• An external 5 V USB charger (5V_USB_CHGR) connected to CN1
• An external 3.3 V power supply (3V3) connected to CN8 pin 7 or CN11 pin 16
The power supply is provided either by the host PC through the USB cable or by an external

Figure 10. Power supply input from STLINK-V3E USB connector with PC (5 V, 500 mA max)
If the USB enumeration succeeds, the 5V_ST_LINK power is enabled, by asserting the
PWR_ENn signal from STM32F723IEK6 ‘STLINK-V3E’ (U7). This pin is connected to a
power switch STMPS2151STR (U2), which powers the board. The power switch
STMPS2151STR (U2) features also a current limitation to protect the PC in case of shortcircuit onboard. If an overcurrent (more than 500
mA) happens onboard, the red LED LD6 is
lit.
Nucleo board and its shield on it can be powered from STLINK-V3E USB connector CN1,
but only the STLINK-V3E circuit gets power before USB enumeration because the host PC
only provides 100
mA to the board at that time.
During the USB enumeration, the Nucleo board asks for the 500 mA 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 switch STMPS2151STR is switched
ON, the Green LED LD5 is turned ON, thus Nucleo board and its shield on it can
consume 500 mA current, but no more.
• If the host is not able to provide the requested current, the enumeration fails.
Therefore, the STMPS2151STR power switch (U2) remains OFF and the MCU part
including the extension board is not powered. As a consequence, the GREEN LED
LD5 remains turned OFF. In this case, it is mandatory to use an external power supply.
Warning: In case the maximum current consumption of the
STM32H7 Nucleo-144 board and its shield boards exceed
300 mA, it is mandatory to power the STM32H7 Nucleo-144
board, using an external power supply connected to E5V, V
or +3.3 V.
6.4.2 External power supply input from VIN (7 V to 12 V, 800 mA max)
IN
When STM32H7 Nucleo-144 board is power supplied by VIN (Refer to Tab le 6 and
Figure 11), the jumper configuration must be the following: Jumper JP2 on pin 3-4 ‘VIN’

6.4.6 Debugging while using VIN or EXT as an external power supply
When powered by VIN or EXT, it is still possible to use the STLINK-V3E for programming or
debugging only, but it is mandatory to power the board first using VIN or EXT, then to
connect the USB cable to the PC. In this way, the enumeration succeeds, thanks to the
external power source.
The following power-sequence procedure must be respected:
1. Connect jumper JP2 between pin 5 and pin 6 for EXT or between pin 3 and pin 4 for
VIN
2. Connect the external power source to VIN or EXT
3. Power on the external power supply 7 V< VIN < 12 V to VIN, or 5 V for EXT
4. Check that the green LED LD5 is turned ON
5. Connect the PC to the USB connector CN1
If this order is not respected, the board may be powered by USB (U5V) first, then by VIN or
EXT as the following risks may be encountered:
1. If more than 300 mA current is needed by the board, the PC may be damaged or the
current supplied can be limited by the PC. As a consequence, the board is not powered
correctly.
2. 300 mA is requested at enumeration so there is a risk that the request is rejected and
the enumeration does not succeed if the PC cannot provide such current.
Consequently, the board is not power supplied (LED LD5 remains OFF).

6.5 Clock sources
6.5.1 HSE clock (high-speed external clock)
There are four ways to configure the pins corresponding to the external high-speed clock
(HSE):
• MCO from STLINK-V3E (default): MCO output of ST-LINK is used as an input clock.
This frequency cannot be changed, it is fixed at 8 MHz and connected to the PF0/PH0OSC_IN of STM32H7 Series microcontroller. The configuration must be:
– SB44 and SB46 OFF
–SB45 ON
– SB3 and SB4 OFF
• HSE on-board oscillator from X3 crystal (not provided): for typical frequencies and its
capacitors and resistors, refer to the STM32H7 Series microcontroller datasheet and to
the Oscillator design guide for STM8AF/AL/S and STM32 microcontrollers Application
note (AN2867) for the oscillator design guide. The X3 crystal has the following
characteristics: 25 MHz, 6 pF, 20 ppm. It is recommended to use
NX2016SA-25MHz-EXS00A-CS11321 manufactured by NDK. The configuration must
be:
– SB44 and SB46 OFF
– SB3 and SB4 ON
– C69 and C70 soldered with 5.6 pF capacitors
–SB45 OFF
Oscillator from external PF0/PH0: from an external oscillator through the pin 29 of the CN11
connector. The configuration must be:
–SB46 ON
–SB45 OFF
– SB3 and SB4 OFF
• HSE not used: PF0/PH0 and PF1/PH1 are used as GPIOs instead of clocks. The
configuration must be:
– SB44 and SB46 ON
–SB45 OFF
– SB3 and SB4 OFF
6.5.2 LSE clock (low-speed external clock) - 32.768 kHz
There are three ways to configure the pins corresponding to the low-speed clock (LSE):
• On-board oscillator (default): X2 crystal. Refer to the Oscillator design guide for
STM8AF/AL/S and STM32 microcontrollers Application note (AN2867) for oscillator
design guide for STM32H7 Series microcontrollers. It is recommended to use

– SB40 and SB41 OFF
– R38 and R39 ON
• Oscillator from external PC14: from external oscillator through the pin 25 of CN11
connector. The configuration must be:
– SB40 and SB41 ON
– R38 and R39 OFF
• LSE not used: PC14 and PC15 are used as GPIOs instead of the low-speed clock.
The configuration must be:
– SB40 and SB41 ON
– R38 and R39 OFF
6.6 Board functions
6.6.1 LEDs
User LD1: a green user LED is connected to the STM32H7 I/O PB0 (SB39 ON and SB47
OFF) or PA5 (SB47 ON and SB39 OFF) corresponding to the ST Zio D13.
User LD2: a yellow user LED is connected to PE1.
User LD3: a red user LED is connected to PB14.
These user LEDs are on when the I/O is HIGH value, and are off when the I/O is LOW.
LD4 COM: the tricolor LED LD4 (green, orange, red) provides information about ST-LINK
communication status. LD4 default color is red. LD4 turns to green to indicate that
communication is in progress between the PC and the STLINK-V3E, with the following
setup:
• Slow blinking red/OFF at power-on before USB initialization
• Fast blinking red/OFF after the first correct communication between PC and
STLINK-V3E (enumeration)
• Red LED ON when the initialization between the PC and STLINK-V3E is complete
• Green LED ON after a successful target communication initialization
• Blinking red/green during communication with the target
• Green ON communication finished and successful
• Orange ON communication failure
LD5 PWR: the green LED indicates that the STM32H7 part is powered and +5 V power is
available on CN8 pin 9 and CN11 pin 18.
LD6 USB power fault: LD5 indicates that the board power consumption on USB exceeds
500
mA, consequently the user must power the board using an external power supply.
LD7 and LD8 USB FS: Refer to Section 6.6.6: USB OTG FS.

6.6.2 Push-buttons
B1 USER (blue button): the user button is connected to the I/O PC13 by default (tamper
support: SB51 ON and SB58 OFF) or PA0 (Wakeup support: SB58 ON and SB51 OFF) of
the STM32H7 Series microcontroller.
B2 RESET (black button): this push-button is connected to NRST and is used to reset the
STM32H7 Series microcontroller.
6.6.3 MCU voltage selection: 1V8/3V3
The STM32H7 Nucleo-144 board offers the possibility to supply the STM32H7 Series
microcontroller with 1.8
• Place the JP5 jumper on 3V3 to supply the MCU with 3V3, connecting pins 1 and 2.
• Place the JP5 jumper on 1V8 to supply the MCU with 1V8, connecting pins 2 and 3.
V or 3.3 V. JP5 is used to select the VDD_MCU power level.
6.6.4 Current consumption measurement (IDD)
Jumper JP4, labeled IDD, is used to measure the STM32H7 Series microcontroller
consumption by removing the jumper and by connecting an ammeter:
• JP4 must be ON when STM32H7 is powered with 3V3_VDD (default)
• If JP4 is OFF, an ammeter must be connected to measure the STM32H7 current. If
there is no ammeter, the STM32H7 is not powered.
Warning: on MB1364 REV.C, ‘VDD_MCU’ is also supplying Ethernet
PHY (U15) and debug voltage translation (U1 and U10).
If needed, for low power measurement (for example standby mode), in order to measure
only MCU (U7) power consumption, the user must remove the following components: R4,
R43, R44, R45, R46, R47, R48, R49, R50, R51, R52, R53, R59, R61, U1, U10, U15, and
SB45.
After removing these components, it becomes impossible to use Ethernet, and 1.8 V debug
with STLINK-V3E.
6.6.5 Virtual COM port (VCP): LPUART/USART
The STM32H7 Nucleo-144 board offers the possibility to connect an LPUART or a USART
interface to the STLINK-V3E or to the ST morpho connectors and ARDUINO
connectors.
The selection is done by settings the related solder bridges. (Refer to Tab le 10 and Table 11
below).
By default the USART3 communication between the target STM32H7 and the STLINK-V3E
is enabled, to support the Virtual COM port for the Mbed (SB5 and SB6 ON).

hardware modifications are required on the NUCLEO board. Flying wires have to be
connected between PD8/PD9 (USART3 available on SB19/SB12) and PB10/PB11
(USART1 available on CN15).
6.6.6 USB OTG FS
The STM32H7 Nucleo-144 board supports USB OTG FS communication via a USB MicroAB connector (CN13) and USB power switch (U18) connected to V
Warning: USB Micro-AB connector (CN13) cannot power the Nucleo-
144 board. To avoid damaging the STM32H7, it is mandatory
to power the Nucleo-144 before connecting a USB cable on
CN13. Otherwise, there is a risk of current injection on
STM32H7 I/Os.
A green LED LD8 lights in one of these cases:
• Power switch (U12) is ON and STM32H7 Nucleo-144 board works as a USB host
• V
is powered by another USB host when the STM32H7 Nucleo-144 board works as
BUS
a USB device.
The red LED LD7 lights if overcurrent occurs when +5 V is enabled on V
mode.

The ST morpho connector consists of male pin header footprints CN11 and CN12 (not
soldered by default). They are used to connect the STM32H7 Nucleo-144 board to an
extension board or a prototype/wrapping board placed on top of the STM32H7 Nucleo-144
board. All signals and power pins of the STM32H7 are available on the ST morpho
connector. This connector can also be probed by an oscilloscope, logical analyzer, or
voltmeter.
Table 22 shows the pin assignments of each STM32H7 on the ST morpho connector.

1. The default state of BOOT0 is 0. It can be set to 1 when a jumper is plugged on the pins 5-7 of CN11.
2. 5V_USB_STLK is the 5 V power coming from the ST-LINKV3 USB connector that rises before and it rises before the +5 V
rising on the board.
3. PA13 and PA14 are shared with SWD signals connected to STLINK-V3. It is not recommended to use them as I/O pins.

Nucleo-144 boards information UM2407
9 Nucleo-144 boards information
9.1 Product marking
The sticker located on the top or bottom side of the PCB board shows the information about
product identification such as board reference, revision, and serial number.
The first identification line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx”
is the board reference, “Variant” (optional) identifies the mounting variant when several
exist, "y" is the PCB revision and "zz" is the assembly revision: for example B01.
The second identification line is the board serial number used for traceability.
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore 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.
“E” or “ES” marking examples of location:
• On the target STM32 that is soldered on the board (for illustration of STM32 marking,
refer to the STM32 datasheet “Package information” paragraph at the www.st.com
website).
• Next to the evaluation tool ordering part number that is stuck or silk-screen printed on
the board.
These boards feature a specific STM32H7 device version that allows the operation of any
stack or library. This STM32H7 device shows a ‘U’ marking option at the end of the standard
part number and is not available for sales.
The board reference for the STM32H7 Nucleo-144 boards is MB1364.
9.2 Board revision history
Revision C-01

9.3 Known limitations
Revision C-01
The IDD measurement of the STM32H7x3 MCU cannot be done in standby mode because
of ETH PHY U15 and the pull-up resistors (R40/R43/R46/R47/R48) supplied by VDD_MCU.
Revision E-01
The IDD measurement of the STM32H7x3 MCU can be measured in standby mode. The
ETH PHY is powered from VDD and is separated from VDD_MCU.
The silkscreen has been corrected on the morpho connectors.
