STM32 Nucleo-144 boards
Introduction
The STM32 Nucleo-144 boards (NUCLEO-L496ZG and NUCLEO-L496ZG-P) 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 STM32 microcontroller. The ST Zio connector, which extends the Arduino™
Uno V3 connectivity, and the ST morpho headers provide an easy means of expanding the
functionality of the Nucleo open development platform with a wide choice of specialized
shields. The STM32 Nucleo-144 board does not require any separate probe as it integrates
the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-144 board comes with the
STM32 comprehensive software HAL and LL libraries, and various packaged software
examples.

Cuttable PCB
An STM32 Nucleo-144 board is divided into two parts: ST-LINK and target STM32. The
ST-LINK part of the PCB can be cut out to reduce the board size. In this case the remaining
target STM32 part can only be powered by VIN, E5V and 3.3 V on the ST morpho connector
CN11, or by VIN and 3.3 V on the ST Zio connector CN8. It is still possible to use the STLINK part to program the STM32, using wires between the CN5 and SWD available signals
on the ST morpho connector (SWCLK CN11 pin 15, SWDIO CN11 pin 13 and NRST CN11
pin 14, same I/O level as VDD_MCU).
6.4
Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo-144
board.
The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about
debugging and programming features refer to ST-LINK/V2 in-circuit debugger/programmer
for STM8 and STM32, User manual (UM1075), which describes in details all the STLINK/V2 features.
The changes versus ST-LINK/V2 version are listed below. New features supported on STLINK/V2-1:
•
USB software re-enumeration
•
Virtual COM port interface on USB
•
Mass storage interface on USB
•
USB power management request for more than 100 mA power on USB
Features not supported on ST-LINK/V2-1:
•
SWIM interface
•
Minimum supported application voltage limited to 3 V
There are two different ways to use the embedded ST-LINK/V2-1, depending on the jumper
state (see Table 4):
•
Program/debug the STM32 on board
•
Program/debug the STM32 in an external application board, using a cable connected to
SWD connector CN5

Drivers
Before connecting the Nucleo-144 board to a Windows® (XP, 7, 8 and 10) PC via USB,
install the driver for ST-LINK/V2-1 that can be downloaded from the www.st.com website.
In case the STM32 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 STM32 Nucleo-144 board to this dedicated driver,
must be updated in the device manager manually.
Note:
It is recommended to proceed by using USB Composite Device, as shown in Figure 8.

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 lifetime of the ST-LINK/V2-1 product (for
example new functionalities, bug fixes, support for new microcontroller families), it is
recommended to keep the ST-LINK/V2-1 firmware up to date before starting to use an
STM32 Nucleo-144 board. The latest version of this firmware is available from the
www.st.com website.

Using the ST-LINK/V2-1 to program and debug the on-board STM32
To program the on-board STM32, place the two jumpers marked in red on the connector
CN4, as shown in Figure 9. The CN5 connector must not be used, since it could disturb the
communication with the STM32 microcontroller of the Nucleo-144 board.

Using ST-LINK/V2-1 to program and debug an external STM32
application
It is very easy to use the ST-LINK/V2-1 to program the STM32 on an external application.
Simply remove the two jumpers from CN4, as shown in Figure 10 and connect the
application to the CN5 debug connector according to Table 5.
Note:
JP3 NRST (target STM32 RESET) must be open when CN5 pin 5 is used in an external
application.

Power supply and power selection
The power supply is provided either by the host PC through the USB cable or by an external
source: VIN (7 V-12 V), E5V (5 V) or +3.3 V power supply pins on CN8 or CN11. In case VIN,
E5V or +3.3 V is used to power a Nucleo-144 board, this power source must comply with the
standard EN-60950-1: 2006+A11/2009 and must be Safety Extra Low Voltage (SELV) with
limited power capability.
In case the power supply is +3.3 V, the ST-LINK is not powered and cannot be used.
6.5.1
Power supply input from ST-LINK/V2-1 USB connector
The STM32 Nucleo-144 board and shield can be powered from the ST-LINK USB connector
CN1 (U5V), by placing a jumper between the pins 3 and 4 of JP6, as shown in Table 7:
Power related jumper. Note that only the ST-LINK part is power supplied before the USB
enumeration, as the host PC only provides 100 mA to the board at that time. During the
USB enumeration, the STM32 Nucleo-144 board requires 300 mA of current to the host PC.
If the host is able to provide the required power, the targeted STM32 microcontroller is
powered and the green LED LD6 is turned ON, thus the STM32 Nucleo-144 board and its
shield can consume a maximum current of 300 mA, not more. If the host is not able to
provide the required current, the targeted STM32 microcontroller and the extension boards
are not power supplied. As a consequence the green LED LD6 stays turned OFF. In such
case it is mandatory to use an external power supply as explained in the next section.
After the USB enumeration succeeds, the ST-LINK U5V power is enabled, by asserting the
PWR_EN pin. 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 short-circuit
on board. If an overcurrent (more than 500 mA) happens on board, the red LED LD5 lits up.
Warning:
In case the maximum current consumption of the STM32
Nucleo-144 board and its shield boards exceed 300 mA, it is
mandatory to power the STM32 Nucleo-144 board, using an
external power supply connected to E5V, VIN or +3.3 V.
Note:
In case the board is powered by a USB charger, there is no USB enumeration, so the green
LED LD6 stays in OFF state permanently and the target STM32 is not powered. In this
specific case a jumper must be placed between pin 5 and pin 6 of JP6, to allow the board to
be powered anyway.
6.5.2
External power supply inputs
An external power source supplies in three different ways a Nucleo-144 board and its shield
boards, depending on the used voltage. The three power sources are summarized in the
Table 6.
When an STM32 Nucleo-144 board is power supplied by VIN or E5V, the jumper configuration
must be the following:
20/48
•
Jumper JP6 on pin 1 and pin 2 for E5V or jumper JP3 on pin 7 and pin 8 for VIN
•
Jumper JP1 OFF

Using VIN or E5V as an external power supply
When powered by VIN or E5V, it is still possible to use the ST-LINK for only programming or
debugging, but it is mandatory to power the board first using VIN or E5V, 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 JP6 between pin 1 and pin 2 for E5V or between pin 7 and pin 8 for VIN
2.
Check that JP1 is removed
3.
Connect the external power source to VIN or E5V
4.
Power on the external power supply 7 V< VIN < 12 V to VIN, or 5 V for E5V
5.
Check that the green LED LD6 is turned ON
6.
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
E5V as the following risks may be encountered:
22/48
1.
If the board needs more than 300 mA, 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 during the enumeration phase (since JP1 must be OFF) so there
is the risk that the request is rejected and the enumeration does not succeed if the PC
DocID030347 Rev 2
UM2179
Hardware layout and configuration
cannot provide such current. Consequently the board is not power supplied (LED LD6
remains OFF).
External power supply input: + 3.3 V
It can be interesting to use the +3.3 V (CN8 pin 7 or CN11 pin 16) directly as power input, in
case the 3.3 V is provided by a shield board. In this case, the ST-LINK is not powered thus
the programming and debugging features are not available.
When the board is powered with +3.3 V, two different configurations are possible:
6.5.3
•
ST-LINK is removed (PCB cut)
•
SB6 (3.3 V regulator) and JP3 (NRST) are OFF
External power supply output
When powered by USB, VIN or E5V, the +5 V (CN8 pin 9 or CN11 pin 18) can be used as
output power supply for an ST Zio shield or an extension board. In this case, the maximum
current of the power source specified in Table 6: External power sources must be respected.
The +3.3 V (CN8 pin 7 or CN11 pin 16) can also be used as power supply output. The
current is limited by the maximum current capability of the regulator U6 (500 mA max).
6.5.4
SMPS power supply
Power figures in Run Mode are significantly improved, by generating Vcore logic supply from
the external DC/DC converter (this function is only available on '-P' suffixed boards).
Board is populated with two different SMPS mounted on U15 and U16:
•
SMPS U15 allows to dynamically supply the VDD_1V2 pins in Run mode at 1.1 V with a
maximum current of 30 mA.
•
SMPS U16 allows to supply the VDD_MCU pins at 1.8 V with a maximum current of
50 mA. When SB125 is open and SB120 closed, the SMPS can deliver higher current
to the expense of higher consumption. This SMPS is disabled by default (See Table 10:
Solder bridge and jumper configuration).
VDD_MCU solder bridge configuration:
•
3.3 V (default): SB122 closed, SB121 and SB127 open
•
1.8 V: SB122 open, and SB121 and SB127 closed (best ULPBench score)
Note:
The ST-LINK is still available in this configuration thanks to the level shifter U14.
6.6
LEDs
User LD1: a green user LED is connected to the STM32 I/O PC7 (SB124 ON and SB123
OFF) or PA5 (SB123 ON and SB124 OFF) corresponding to the ST Zio D13. It only works
when VCC_MCU is 3.3 V.
User LD2: a blue user LED is connected to PB7.
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 and red) provides information about ST-LINK
communication status. LD4 default color is red. LD4 turns to green to indicate that t h e

communication is in progress between the PC and the ST-LINK/V2-1, 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 ST-LINK/V21 (enumeration)
•
Red LED on: when the initialization between the PC and ST-LINK/V2-1 is complete
•
Green LED on: after a successful target communication initialization
•
Blinking red/green: during communication with target
•
Green on: communication finished and successful
•
Orange on: communication failure
LD5 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.
LD6 PWR: the green LED indicates that the STM32 part is powered and +5 V power is
available on CN8 pin 9 and CN11 pin 18.
LD7 and LD8 USB FS: refer to Section 6.12: USB FS OTG .
Note:1
LD1 is connected to U8 and it is driven by PC7 or PA5 which may be changed to 1.8 V I/O,
so LD1 cannot be lit when VDD is set to 1.8 V.
Note:2
LD2, LD3 cannot work with VDD_MCU= 1.8 V

Push-buttons
B1 USER: the user button is connected to the I/O PC13 by default (Tamper support, SB197
ON and SB178 OFF) or PA0 (Wakeup support, SB178 ON and SB197 OFF) of the STM32.
B2 RESET: this push-button is connected to NRST and is used to RESET the STM32.
6.8
JP5 (IDD)
The jumper JP5, labeled IDD, is used to measure the STM32 microcontroller consumption by
removing the jumper and by connecting an ammeter:

•
JP5 ON: STM32 is powered (default)
•
JP5 OFF: an ammeter must be connected to measure the STM32 current. If there is no
ammeter, the STM32 is not powered

LPUART1 communication
The LPUART1 interface available on PG7 and PG8 of the STM32 can be connected to the
ST-LINK or to the ST morpho connector. Another option to do this connection is to set the
related solder bridges. By default the LPUART1 communication between the target STM32
and the ST-LINK is enabled, to support the virtual COM port (SB130 and SB131 ON). Refer
to Table 8.

USB FS OTG
An STM32 Nucleo-144 board supports the USB OTG as host or as device-full-speed
communication via a USB Micro-AB connector (CN14) and USB power switch (U12)
connected to VBUS.
Warning:
USB Micro–AB connector (CN14) cannot power a Nucleo-144
board. To avoid damaging the STM32, it is mandatory to
power the board before connecting a USB cable on CN14.
Otherwise there is a risk of current injection on STM32 I/Os.
A green LED LD8 lits up in one of these cases:
•
Power switch (U12) is ON and STM32 Nucleo-144 board works as a USB host
•
VBUS is powered by another USB host when the STM32 Nucleo-144 board works as a
USB device.
The red LED LD7 lits up if overcurrent occurs when +5 V is enabled on VBUS in USB host
mode.

ST Zio connectors
The connectors CN7, CN8, CN9 and CN10 are female on top side and male on bottom side
of an STM32 Nucleo-144 board. They include support for Arduino Uno V3. Most shields
designed for Arduino Uno V3 can fit to the STM32 Nucleo-144 board.
Caution:
The I/Os of the STM32 microcontroller are 3.3 V compatible, while Arduino Uno V3 is 5 V
compatible.
Table 11 shows the pin assignments for the STM32 on the ST Zio connector.

ST morpho connector
The ST morpho connector consists in male pin header footprints CN11 and CN12 (not
soldered by default). They can be used to connect the STM32 Nucleo-144 board to an
extension board or a prototype/wrapping board placed on top of the STM32 Nucleo-144
board. All signals and power pins of the STM32 are available on the ST morpho connector.
This connector can also be probed by an oscilloscope, logical analyzer or voltmeter.
Table 12 shows the pin assignments of each STM32 on the ST morpho connector.
