STM32 Nucleo-144 boards
Introduction
The STM32 Nucleo-144 boards (NUCLEO-L496ZG, NUCLEO-L496ZG-P and NUCLEO-L4R5ZI) 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.

6.3 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 ST-LINK 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 ST- LINK/V2 features.
The changes versus ST-LINK/V2 version are listed below. New features supported on ST-LINK/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
Table 4. CN4 states of the jumpers
Jumper state Description
Both CN4 jumpers ONST-LINK/V2-1 functions enabled for on-board programming (default). See Section 6.4.3.
Both CN4 jumpers OFFST-LINK/V2-1 functions enabled for external CN5 connector (SWD supported). See Section 6.4.4.

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.

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

6.5 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 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: 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
Hardware layout and configuration UM2179
22/50 DocID030347 Rev 5
The 5 V power source is selected by the jumper JP6 as shown in Table 7.

From 7 V to 12 V only and input current capability is linked to input voltage:

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:
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 cannot provide such current. Consequently the board is not power supplied (LED LD6 remains OFF).
External power supply input: + 3.3 V
If 3.3 V is provided by a shield board, it is worth using the +3.3 V (CN8 pin 7 or CN11 pin 16) directly as power input. 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:
• ST-LINK is removed (PCB cut)
• SB6 (3.3 V regulator) and JP3 (NRST) are OFF
6.5.3 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 opened and SB120 closed, the SMPS can deliver higher
Hardware layout and configuration UM2179
24/50 DocID030347 Rev 5
current but with higher consumption. This SMPS is disabled by default (See Table 10: Configuration of the solder bridges and jumpers).
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 the 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/V2-1 (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
6.7 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
6.9 OSC clock
6.9.1 OSC clock supply
There are four ways to configure the pins corresponding to the external high-speed clock (HSE):
• HSE not used (Default): PF0/PH1 and PF1/PH1 are used as GPIOs instead of as clock. The configuration must be:
– SB147 and SB156 ON
– SB109 and SB148 (MCO) OFF
– SB12 and SB13 removed
• MCO from ST-LINK: MCO output of ST-LINK is used as input clock. This frequency cannot be changed, it is fixed at 8 MHz and connected to the
• PF0/PH0-OSC_IN of STM32 microcontroller. The configuration must be:
– SB147 OFF
– SB109 and SB148 ON
– SB12 and SB13 OFF
• HSE on-board oscillator from X3 crystal (not provided): for typical frequencies and its capacitors and resistors, refer to the STM32 microcontroller datasheet and for the oscillator design guide refer to the Oscillator design guide for STM8S, STM8A and STM32 microcontrollers Application note (AN2867). The X3 crystal has the following characteristics: 8 MHz, 8 pF, 20 ppm. It is recommended to use the NX3225GD-8.000M- EXS00A-CG04874 crystal manufactured by NIHON DEMPA KOGYO CO., LTD. The configuration must be:
– SB147 and SB156 OFF
– SB12 and SB13 soldered
– C37 and C38 soldered with 4.3 pF capacitors
– SB109 and SB148 OFF
• Oscillator from external PF0/PH0: from an external oscillator through the pin 29 of the CN11 connector. The configuration must be:
– SB147 ON
– SB109 and SB148 OFF
– SB12 and SB13 removed

26/50 DocID030347 Rev 5
6.10 OSC 32 KHz clock supply
There are three ways to configure the pins corresponding to low-speed clock (LSE):
• On-board oscillator (Default): X2 crystal. Refer to the Oscillator design guide for STM8S, STM8A and STM32 microcontrollers Application note (AN2867) for oscillator design guide for STM32 microcontrollers. It is recommended to use the NX3214SA- 32.768KHZ-EXS00A-MU00525 (32.768 KHz, 6 pF load capacitance, 200 ppm) crystal from Nihon Dempa Kogyo CO, LTD.
• Oscillator from external PC14: from external oscillator through the pin 25 of CN11 connector. The configuration must be:
– SB145 and SB146 ON
– R39 and R40 removed
• LSE not used: PC14 and PC15 are used as GPIOs instead of low-speed clock. The configuration must be:
– SB145 and SB146 ON
– R39 and R40 removed
6.11 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.
6.12 USB FS OTG
The STM32 Nucleo-144 board supports the USB OTG as host or as device-full-speed communication through a USB Micro-AB connector (CN14) and USB power switch (U12) connected to VBUS.
Warning: The 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.
Note:1 It is recommended to power the Nucleo-144 board with an external power supply when using the USB OTG or the host function.
Note:2 JP4 must be closed when using the USB OTG FS.
Note:3 Limitation: when the cable is not connected, PA9 (VBUS) is not floating, because internal pull up of PA12 (D+) impacts PA9 through ESD protection part USBLC6-2SC6 (U13).
For pin configuration refer to Table 9.

6.17 Bootloader limitation
6.17.1 Bootloader operation
Boot from system Flash memory runs bootloader code stored in the system Flash memory protected against writing and erasing. This allows in-system programming (ISP) with flashing of the STM32 user Flash memory. It also allows writing data into the RAM. The data is written via the USART, SPI, I2C, USB or CAN communication interface.

1. 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. VREF+ is not connected to CN12 by default.
3. U5V is the +5V power signal, coming from the ST-LINKV2-1 USB connector. It rises before the +5V signal of the board.
4. PA13 and PA14 are shared with SWD signals connected to ST-LINK/V2-1. If ST-LINK part is not cut, it is not recommended to use them as I/O pins.
5. PB11 and PG15 are not available on the NUCLEO-L496ZG-P board.

6.17.2 Bootloader identification
The bootloader version is identified by reading the bootloader ID at address 0x1FFF 6FFE:
• the bootloader ID is 0x91 for bootloader version V9.1.
• the bootloader ID is 0x92 for bootloader version V9.2.
6.17.3 Bootloader limitation
The limitation existing in bootloader V9.1 causes user Flash memory data to get randomly corrupted when written via the bootloader SPI interface.
As a result, during bootloader SPI Write Flash operation, some random 64-bits (2 double-words) may be left blank at 0xFF.
6.17.4 Affected parts
The STM32L496ZGT6, STM32L496ZGT6P, and STM32L4R5ZIT6 parts respectively soldered on the NUCLEO-L496ZG, NUCLEO-L496ZG-P, and NUCLEO-L4R5ZI main boards are marked with a date code corresponding to their manufacturing dates.
The STM32L496ZGT6, STM32L496ZGT6P, and STM32L4R5ZIT6 parts with a date code prior or equal to week 37 of 2017 are fitted with bootloader V9.1. They are affected by the limitation described in Section 6.17.3 and require one of the workarounds proposed in Section 6.17.5.
The parts with a date code equal to week 38 of 2017 or later contain bootloader V9.2. They are not affected by the limitation.
To locate the visual date code information on the STM32L496ZGT6, STM32L496ZGT6P, or STM32L4R5ZIT6 package, refer to the Package Information section in the data sheet available at www.st.com. The date code related portion of the package marking is in the Y WW format, where Y is the last digit of the year and WW is the week number. For example, a part manufactured in week 38 of 2017 bears the 7 38 date code.
6.17.5 Workarounds
Three workarounds are proposed to overcome the limitation existing with bootloader V9.1.
Workaround 1
Add a delay between sending a Write command and its ACK request. The delay duration must be the duration of the 256-byte Flash-write time.
Workaround 2
Read back after each write operation (256 bytes or end of user code flashing) and, in case of error, perform the write operation again.
Workaround 3
Using the bootloader, load a patch code in RAM to write in Flash memory through the same Write Memory write protocol as the bootloader This patch is provided by STMicroelectronics. The patch code is available for download from the www.st.com website with a readme.txt file containing the instructions of use.
