STM32 Nucleo-144 boards

Introduction
The STM32 Nucleo-144 boards (NUCLEO-L496ZG, NUCLEO-L496ZG-P,
NUCLEO-L4R5ZI, NUCLEO-L4R5ZI-P and NUCLEO-L4A6ZG) 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 free software libraries and examples available with the STM32Cube
package.

Cuttable PCB
The 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.
If 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.
Figure 8. USB composite device

6.4.2

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 the
STM32 Nucleo-144 board. The latest version of this firmware is available from the
www.st.com website.

6.4.3

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 SWD debug connector according to Table 5.

Note:

18/53

JP4 NRST (target STM32 RESET) must be open when CN3 pin 5 is used in an external
application.

Hardware layout and configuration

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. If 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.
If 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 also features a current limitation to protect the PC if a short-circuit happens
on the board. If an overcurrent (more than 500 mA) happens on the board, the red LED LD5
lits up.

Warning:

If the maximum current consumption of the STM32 Nucleo144 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:

If 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 pins 5 and 6 of JP6, to allow the board to be powered
anyway.

6.5.2

External power supply inputs
Depending on the used voltage, an external power source supplies in three different ways
the STM32 Nucleo-144 board and its shield boards. The three power sources are listed in
Table 6.
When the STM32 Nucleo-144 board is power supplied by VIN or E5V, the jumper
configuration must be as showed below:
•

Jumper JP6 on pin 1 and pin 2 for E5V or jumper JP3 on pin 7 and pin 8 for VIN

•

Jumper JP1 OFF
