7 Embedded STLINK-V3EC
The chapter below gives some information about the implementation of STLINK-V3EC.
For more details on STLINK-V3EC such as LEDs management, drivers, and firmware, refer to the technical note
Overview of ST-LINK derivatives (TN1235).
For information about the debugging and programming features of STLINK-V3EC, refer to the user manual
STLINK-V3SET debugger/programmer for STM8 and STM32 (UM2448).
Description
There are two different ways to program and debug the onboard STM32 MCU.
• Using the embedded STLINK-V3EC programming and debugging tool on the NUCLEO-H563ZI board.
• Using an external debug tool connected to the CN5 MIPI20 connector (SWD/JTAG/TRACE)
The STLINK-V3EC facility for debugging and flashing is integrated into the STM32H5 Nucleo-144 board.
Supported features in STLINK-V3EC:
•
5 V/500 mA power supply capability through the USB Type-C® connector (CN1)
• USB 2.0 high-speed-compatible interface
• JTAG and Serial Wire Debug (SWD) with Serial Wire Viewer (SWV)
• Virtual COM port (VCP)
• 1.7 to 3.6 V application voltage
• COM status LED, which blinks during communication with the PC
• Power status LED giving information about STLINK-V3EC target power.
• Overvoltage protection (U2) with current limitation
Two tricolor LEDs (green, orange, and red) provide information about STLINK-V3EC communication status (LD4)
and STLINK-V3EC power status (LD6).
For detailed information about the management of these LEDs, refer to the technical note Overview of ST-LINK
derivatives (TN1235).
UM3115
Embedded STLINK-V3EC
Drivers
The installation of drivers is not mandatory from Windows 10® but allocates an ST-specific name to the ST-LINK
COM port in the system device manager.
For detailed information on the ST-LINK USB drivers, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
STLINK-V3EC firmware upgrade
STLINK-V3EC embeds a firmware upgrade (stsw-link007) mechanism through the USB-C® port. As the
firmware might evolve during the lifetime of the STLINK-V3EC product (for example to add new functionalities, fix
bugs, and support new microcontroller families), it is recommended to keep the
date before starting to use the NUCLEO-H563ZI board. The latest version of this firmware is available from the
www.st.com website.
For detailed information about firmware upgrades, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
Using an external debug tool to program and debug the on-board STM32
Before connecting any external debug tool to the MIPI20 debug connector (CN5), the SWD and VCP signals from
STLINK-V3EC must be isolated. For this, fit the jumper on JP1. It disables the U1 level shifter and isolates SWD
and VCP signals from STLINK-V3EC. The configuration of the JP1 is explained in Table 5.
Once the jumper is fitted on JP1, an external debug tool can be connected to the MIPI20 debug connector (CN5).
The two level shifters U1 and U10 allow compatibility between the target MCU signals (1V8 or 3V3) and the
STLINK-V3EC signals (3V3). They are used on VCP and SWD interfaces to offer a debug capability when
operating the target MCU at 1V8.

Power supply
8 Power supply
Six different sources can provide the power supply to NUCLEO-H563ZI:
• A host PC connected to CN1 through a USB cable (default configuration)
• An external 7 to 12 V power supply connected to CN8 pin 15 or CN11 pin 24 (VIN)
• An external 5 V power supply connected to CN11 pin 6 (5V_EXT)
• An external 5 V USB charger (VBUS_STLK) connected to CN1
• A host PC connected to CN13 through a USB cable
• An external 3.3 V power supply (3V3) connected to CN8 pin 7 or CN11 pin 16
In case VIN, 5V_EXT, or 3V3 is used to power the STM32H5 Nucleo-144 board, this power source must comply
with the EN-60950-1: 2006+A11/2009 standard and must be safety extra low voltage (SELV) with limited power
capability.
In case the power supply is +3.3 V, STLINK-V3EC is not powered and cannot be used.
8.1 Power supply input from STLINK-V3EC USB connector: 5V_STLK (default
configuration)
The 5 V signal on the STLINK-V3EC USB connector (CN1) can power the STM32H5 Nucleo-144 board and its
shield. To select the 5V_STLK power source, JP2 must be set on [1-2] ‘STLK’ (refer to Figure 8).
This is the default configuration.
Figure 8. Power supply input from STLINK-V3EC USB connector with PC (5 V, 500 mA maximum)
PC
5V

3V3
If the USB enumeration succeeds, the ST-LINK power is enabled, by asserting the T_PWR_EN signal from
STLINK-V3EC. This pin is connected to a power switch (U2), which powers the board. The power switch also
features a current limitation to protect the PC in case of a short circuit onboard. If an overcurrent (more than
500 mA) happens onboard, the POWER LED STATUS (LD6) is lit in red color.
The STLINK-V3EC USB connector (CN1) can power the Nucleo board with its shield.
• If the host can provide the required power, the power switch and the green LED (LD5) are turned ON.
Thus, the Nucleo board and its shield can consume up to 500 mA current, but no more.
• If the host is not able to provide the requested current, the enumeration fails.
Therefore, the 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.
DT59064V1
UM3115 - Rev 2
Warning: In case the maximum current consumption of the STM32H5 Nucleo-144 board and its shield
boards exceed 500 mA, it is mandatory to power the STM32H5 Nucleo-144 board, using an
external power supply connected to 5V_EXT, VIN, or 3V3.

8.2 External power supply input from VIN (7 to 12 V, 800 mA maximum)
When the STM32H5 Nucleo-144 board is power supplied by VIN (refer to Table 7 and Figure 9, the JP2 jumper
must be fitted on [3-4] (VIN 5V).
The STM32H5 Nucleo-144 board and its shield boards can be powered in three different ways from the VIN
external power supply, depending on the used voltage. The three power sources are summarized in Table 7.

directly as the power input (refer to Figure 13 and Table 11). In this case, note that programming and debugging
features are unavailable as STLINK-V3EC is not powered.

8.7 Debugging/programming when not using an external power supply
When powered by VIN (VIN 5 V) or 5V_EXT (E5V), it is still possible to use STLINK-V3EC for programming or
debugging only. In this case, it is mandatory to power the board first using VIN 5 V or E5V, then connect the USB
cable from CN1 to the PC. In this way, the enumeration succeeds, thanks to the external power source.
The following power-sequence procedure must be respected:
1. Configure the jumper JP2 [5-6] for E5V or [3-4] for VIN 5V.
2. Connect the external power source to VIN 5 V or E5V.
3. Power on the external power supply 7 V < VIN < 12 V to VIN 5 V, or 5 V for E5V.
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 following risks might be encountered:
1. If the board needs more than 300 mA current, the PC might be damaged, or the PC can limit the supplied
current. As a consequence, the board is not powered correctly.
2. If 300 mA is requested during enumeration, 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. The
green LED (LD5) remains OFF.

9 Clock sources
9.1 HSE clock (high‑speed external clock)
There are four ways to configure the pins corresponding to the high‑speed external clock (HSE):
• MCO from STLINK-V3EC (default): The MCO output of ST-LINK is used as an input clock of the STM32H5.
The MCO clock frequency cannot be changed. It is fixed at 8 MHz and connected to the PF0/PH0‑OSC_IN
of the STM32H5 series microcontroller. The configuration must be:
– SB49 ON
– SB48 and SB50 OFF
– SB3 and SB4 OFF
• HSE on-board oscillator from X3 crystal (provided): For typical frequencies and its capacitors and resistors,
refer to the STM32H5 series microcontroller datasheet and the application note Oscillator design guide for
STM8AF/AL/S, STM32 MCUs and MPUs (AN2867) for the oscillator design guide. The X3 crystal has the
following characteristics: 25 MHz, 6 pF, and 20 ppm. ST recommends using NX2016SA-25MHz-EXS00ACS11321 manufactured by NDK. The configuration must be:
– SB3 and SB4 ON
– C69 and C70 ON with 5.6 pF capacitors
– SB48 and SB50 OFF
– SB49 OFF
• Oscillator from external PF0/PH0: From an external oscillator through pin 29 of the CN11 connector. The
configuration must be:
– SB50 ON
– SB48 and SB49 OFF
– SB3 and SB4 OFF
• HSE not used: PF0/PH0 and PF1/PH1 are used as GPIOs instead of clocks. The configuration must be:
– SB48 and SB50 ON
– SB49 OFF
– SB3 and SB4 OFF
UM3115
Clock sources
9.2
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 application note Oscillator design guide for
STM8AF/AL/S, STM32 MCUs and MPUs (AN2867) for oscillator design guide for STM32H5 series
microcontrollers. ST recommends using NX3215SA-32.768kHZ-EXS00A-MU00525 (32.768 kHz, 9 pf load
capacitance, 20 ppm) from NDK. The configuration must be:
– SB44 and SB45 OFF
– R34 and R35 ON
• Oscillator from external PC14: From an external oscillator through pin 25 of the CN11 connector. The
configuration must be:
– SB45 ON
– SB44 OFF
– R34 and R35 OFF
• LSE not used: PC14 and PC15 are used as GPIOs instead of the low-speed clock.
The configuration must be:
– SB44 and SB45 ON
– R34 and R35 OFF

10.3 MCU voltage selection 1V8/3V3
The STM32H5 Nucleo-144 board offers the possibility to supply the STM32H5 microcontroller with 1.8 or 3.3 V.
JP4 is used to select the VDD_MCU power level:
• JP4 jumper must be fitted on [1-2] to supply the MCU with 3V3
• JP4 jumper must be fitted on [2-3] to supply the MCU with 1V8
10.4 Current consumption measurement (IDD)
The JP5 jumper, labeled IDD, is used to measure the
jumper and by connecting an ammeter:
• JP5 must be ON when STM32H5 is powered with VDD (default)
• If JP5 is OFF, an ammeter must be connected to measure the STM32H5 current. If there is no ammeter,
the STM32H5 is not powered.

10.5 Virtual COM port (VCP): LPUART1/USART3
The STM32H5 Nucleo-144 board offers the flexibility to connect the LPUART1 or the USART3 interface to the
STLINK-V3EC, or to the ST morpho and ARDUINO® Uno V3 connectors.
The selection is done by setting the related solder bridges (refer to Table 12 and Table 13 below).
By default, the serial interface USART3 (PD8/PD9) that supports the bootloader is connected and directly
available as a Virtual COM port of a PC connected to the STLINK-V3EC USB Type-C® connector (CN1).

10.6.1 USB FS device
When a USB Host connection to the USB Type-C® connector (CN13) of the STM32H5 Nucleo-144 board is
detected, the board starts behaving as a USB Device.
Depending on the powering capability of the USB Host, the board can take power from the V
CN13. In the board schematic diagrams, the corresponding power voltage line is called 5V_UCPD. The
Nucleo-144 board supports a 5 V USB voltage, from 4.75 to 5.25 V. On the MCU side, VDD_USB supports the
3V3 voltage only. Section 8 provides information on how to use powering options. The hardware configuration for
the USB FS interface is shown in Table 14.

10.6.2 UCPD
The USB Type-C® introduces the USB power-delivery feature. The STM32H5 Nucleo-144 supports the dead
battery and the Sink mode.
In addition to the DP/DM I/O directly connected to the USB Type-C® connector, five I/Os are also used for UCPD
configuration: Configuration channel (UCPD_CC1 and UCPD_CC2), VBUS-SENSE, UCPD dead battery
(UCPD_DBn), and UCPD_FLT (FAULT) feature.
To protect the STM32H5 Nucleo-144 from USB overvoltage, a Programmable Power Supply (PPS) compliant
USB Type-C® port protection is used: TCPP01‑M12 IEC6100‑4‑2 level 4‑compliant IC:
• Configuration Channel I/O: UCPD_CCx: These signals are connected to the associated CCx line of the

Ethernet
The STM32H5 Nucleo-144 board supports 10M/100M Ethernet communication by a PHY LAN8742A-CZ-TR
(U15) and RJ45 connector (CN14). Ethernet PHY is connected to the STM32H5 series microcontroller via the
RMII interface. The PHY RMII_REF_CLK generates the 50 MHz clock for the STM32H5 series microcontroller.
Note: Make sure that JP6 is ON when using Ethernet.
Note: Ethernet PHY LAN8742A must be set in power-down mode (in this mode, the Ethernet PHY reference clock
turns off) to achieve the expected low-power mode current. This is done by configuring the Ethernet PHY basic
control register (at address
0x00) bit 11 (power down) to '1'. SB58 can also be OFF to get the same effect.

13.2 ST morpho connector
The ST morpho connector consists of male-pin header footprints CN11 and CN12 (not soldered by default). They
are used to connect the STM32H5 Nucleo-144 board to an extension board or a prototype/wrapping board placed
on the top of the ST morpho. All signals and power pins of the STM32H5 are available on the ST morpho
connector. An oscilloscope, logical analyzer, or voltmeter can also probe this connector.
Table 25 shows the pin assignments of each STM32H5 on the ST morpho connector.

14 NUCLEO-H563ZI product information
14.1 Product marking
The stickers located on the top or bottom side of all PCBs provide product information:
• First sticker: product order code and product identification, generally placed on the main board featuring
the target device.
Example:
Product order code
Product identification
• Second sticker: board reference with revision and serial number, available on each PCB.
Example:
MBxxxx-Variant-yzz
syywwxxxxx
On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first 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 line shows the board serial number used for traceability.
Parts marked as “ES” or “E” are not yet qualified and therefore not approved for use in production. ST is not
responsible for any consequences resulting from such use. In no event will ST be liable for the customer using
any of these engineering samples in production. ST’s Quality department must be contacted prior to any decision
to use these engineering samples to run a qualification activity.
“ES” or “E” marking examples of location:
• On the targeted STM32 that is soldered on the board (for an 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.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial
stack/library available. This STM32 device shows a
and is not available for sales.
To use the same commercial stack in their applications, the developers might need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
“U” marking option at the end of the standard part number
