STM32 Nucleo-64-P boards

Introduction

The STM32 Nucleo-64-P boards (NUCLEO-L433RC-P and NUCLEO-L452RE-P) provide
an affordable and flexible way for users to try out new concepts and build prototypes with
the STM32 microcontroller and the external SMPS (switched mode power supply), which
provides various combinations of performance, power consumption and features.

Arduino™ Uno V3 connectivity and 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-64-P boards do not require any separate probe, as they integrate the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64-P boards come with the
comprehensive free STM32 software libraries and examples that are available with the
STM32Cube package.

9.3 Cuttable PCB

An STM32 Nucleo-64-P 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 V
CN5, or by V

It is still possible to use the ST- LINK part to program the STM32, using wires between the
CN3 and SWD available signals on the ST morpho connector (SWCLK CN5 pin 17, SWDIO

9.4.1 Drivers

®

Before connecting the STM32 Nucleo-64-P board to a Windows
through USB, install the driver for

the ST-LINK/V2-1 that is available at the www.st.com

website.

In case the STM32 Nucleo-64-P 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-64-P 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 7.

PC (XP, 7, 8 and 10)

9.4.2 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 an
STM32 Nucleo-64-P board. The latest version of this firmware is available at the www.st.com
website.

9.5 Power supply and power selection

9.5.1 External Power supply input

The STM32 Nucleo-64-P board is designed to be powered by several DC power supply. It is
possible to supply the STM32 Nucleo-64-P board with any of the following sources:

• 5V_ST_LINK from ST-LINK USB connector

• V

• E5V from ST morpho connector

• 5V_USB_CHARGER from ST-LINK USB

• 3.3 V on Arduino connector or ST morpho connector

Note: If an external 5V DC power source is used, the Discovery board must be powered by a

power supply unit or by an auxiliary equipment complying with the standard EN-60950-1:
2006+A11/2009 and must be Safety Extra Low Voltage (SELV) with limited power capability.

5V_ST_LINK is a DC power with limitation from ST-LINK USB connector (USB type Micro-B
connector of ST-LINK/V2-1). In this case JP5 jumper should be on pins 1 and 2 to select
5V_STL power source on silkscreen of JP5. This is the default setting. If the USB
enumeration succeeds, the 5V_ST_LINK power is enabled, by asserting the PWR_ENn
signal (from STM32F103CBT6). 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 in
case of a short-circuit on board (more than 750

mA).

The STM32 Nucleo-64-P board and its shield can be powered from the ST-LINK USB
connector CN1, but only ST-LINK circuit is powered before USB enumeration, because the
host PC only provides 100
STM32 Nucleo-64-P board requires 500

mA to the board at that time. During the USB enumeration,

mA of current to the host PC. If the host is able to
provide the required power, the enumeration ends by a “SetConfiguration” command and
then, the power transistor ST890 is switched ON, the green LED LD3 is turned ON, thus the
STM32 Nucleo-64-P board and its shield request no more than 500

mA current. If the host
is not able to provide the required current, the enumeration fails. Therefore the power switch
ST890 stays OFF and the MCU part including the extension board is not powered. As a
consequence the green LED LD3 stays turned OFF. In this case it is mandatory to use an
external power supply.

Warning: In case the maximum current consumption of the STM32

Nucleo-64-P board and its extension boards exceeds 500 mA,
it is recommended to power the STM32 Nucleo-64-P board
using an external power supply connected to E5V or VIN.

9.5.2 External power supply output

5 V: the 5 V (CN8 pin 5 or CN5 pin 18) can be used as output power supply for an Arduino

shield or an extension board, when the STM32 Nucleo-64-P board is powered by USB, V
or E5V. In this case the maximum current allowed is showed in

Tab l e 7.

IN

3.3 V: on CN8 pin 4 or CN5 pin 16 can be also used as power supply output. The current is
limited by the maximum current capability of the regulator U7 (LD39050PUR33 from
STMicroelectronics). In this condition the maximum consumption of the
STM32 Nucleo-64-P board and the connected shield should be less than 500 mA.

9.5.3 SMPS power supply

Power figures in Run mode are significantly improved by:

• Generating V

from an external connector

• Generating V

from an external connector

logic supply from an external SMPS (switched-mode power supply) or

core

DD_MCU

supply from an external SMPS (switched-mode power supply), or

The STM32 Nucleo-64-P board is populated with two SMPSs, U11 and U13, with the
following functions:

• SMPS U11 allows to supply dynamically the V

DD_1V2

pins in Run mode at 1.1 V with a

maximum current of 30 mA.

• SMPS U13 allows to supply the V

DD_MCU

pin at 1.8 V with a maximum current of
50 mA (hysteresis operation mode). The SMPS U13 can deliver higher current (PWM
operation mode) but with less efficiency. To set the U13 SMPS in PWM mode remove
SB80 and solder SB79. This SMPS is enabled by default.

9.6 Programming/debugging when the power supply is not from ST-LINK (5V_ST_link)

VIN or E5V is used as an external power supply in case the current consumption of the
STM32 Nucleo-64-P board and its extension boards exceed the allowed current on the
USB. In such condition it is still possible to use the USB for communication, programming or
debugging only.

In this case it is mandatory to power the board first using VIN or E5V then to connect the
USB cable to the PC. Proceeding this way the enumeration succeeds, thanks to the external
power source.

The following power sequence procedure must be respected:

1. Connect jumper JP5 between pins 3 and 4 for VIN or pins 5 and 6 for E5V

2. Be sure that SB9 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 LD3 is turned ON

6. Connect the PC to the USB connector CN1

If this sequence is not respected, the board may be powered by V
with the following risks:

• If more than 500 mA current is needed by the board, the PC may be damaged or the
current supplied may be limited by the PC. As a consequence the board is not powered
correctly.

• 500 mA is requested at the enumeration (since SB9 must be OFF): this request can be
rejected and the enumeration does not succeed if the PC cannot provide such current,
consequently the board is not power supplied (LED LD3 remains OFF).

9.7 OSC clock sources

Three clock sources are listed below:

• LSE which is the 32.768 KHz crystal for the STM32 embedded RTC

• MCO which is the 8 MHz clock from the ST-LINK MCU for the STM32 microcontroller

• HSE which is the 8 MHz oscillator for the STM32 microcontroller. This clock is not

implemented on the STM32 Nucleo-64-P board.

9.7.1 LSE: OSC 32 KHz clock supply

There are three ways to configure the pins corresponding to the low-speed clock (LSE):

LSE on-board oscillator X3 crystal (Default configuration). Refer to Oscillator design
guide for STM8S, STM8A and STM32 microcontrollers Application note (AN2867) for

manufactured by NDK.

The following configuration is needed:

• SB64, SB68, SB70 OFF

• SB67 and SB69 ON

• C47 and C48 soldered with 8.2 pF capacitors

External oscillator to PH0 input (Default: not connected): from an external oscillator
through pin 29 of the CN5 connector.

The following configuration is needed:

• SB64, SB67 and SB69 OFF

• SB70 ON

• In this configuration PH1 is used as I/O (SB68 ON)

HSE not used (Default configuration): PH0 and PH1 are used as GPIO and not as clock.

9.10 LEDs

Four LEDs are available on the STM32 Nucleo-64-P board. The four LEDs are located on
the top side of the board.

26/54 DocID030544 Rev 2

UM2206 Hardware layout and configuration

LD1 COM: LD1 is a bi-color LED. LD1 default status is red. LD1 turns to green to indicate

that communication is in progress between the PC and the ST-LINK/V2-1 as follow:

• Slow blinking red/off: at power-on before USB initialization

• Fast blinking red/off: after the first correct communication between the PC and the

ST-LINK/V2-1 (enumeration)

• Red LED on: when initialization between the PC and the ST-LINK/V2-1 is successfully
ended

• Green LED on: after successful STM32 communication initialization

• Blinking red/green: during communication with STM32

• Green on: communication well ended

• Orange on: communication ended with failure

LD4 USER: this green LED is a user LED connected to Arduino signal D13 corresponding
to STM32 I/O PB13. To light the LED a high-logic state “1” has to be written in the
corresponding GPIO. A transistor is used to drive the LED when the I/O voltage is 1.8
LD4 consumption does not impact the V
isolated from it.

9.11 Push buttons

Two buttons are available on the STM32 Nucleo-64-P board.

• B1 USER: the blue button for user and wake-up function is connected to the I/O PC13
(default) or to I/O PA0 (optional) of the STM32. When the button is depressed the logic
state is “1”, otherwise the logic state is “0”.

• B2 RESET: the black button is connected to NRST and is used to RESET the STM32.
When the button is depressed the logic state is “0”, otherwise the logic state is “1”.

The blue and black plastic hats placed on these push-buttons can be removed if necessary
when a shield or an application board is plugged on top of the STM32 Nucleo-64-P board.
This is to avoid pressure on the buttons and consequently a possible permanent STM32
