STM32 Nucleo-64-P boards (MB1319)
Introduction
The STM32 Nucleo-64-P boards, based on the MB1319 reference board (NUCLEO-
L412RB-P, 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.

5 Quick start
This section describes how to start development quickly using the STM32 Nucleo-64-P
board.
Before installing and using the product, accept the Evaluation Product License Agreement
from the www.st.com/epla webpage.
5.1 Getting started
The STM32 Nucleo-64-P board is a low-cost and easy-to-use development kit to evaluate
and start quickly a development with an STM32 microcontroller in an LQFP64 package. To
start using this board, follow the steps below:
1. Check the jumper position on the board, as shown in Table 4: Default jumper settings.
2. For correct identification of all device interfaces from the host PC, install the Nucleo
USB driver available on the www.st.com/stm32nucleo webpage, before connecting the
board.
3. To power the board, connect the Nucleo-64-P board before a PC with a USB Type-A or
USB Type-C® to Micro-B cable through USB connector CN1. As a result, the green
LED LD3 (5 V PWR) lights up, LD1 (COM) and green LED LD4 blink.
4. Press user button B1 (blue).
5. Observe that the blinking frequency of the three green LEDs LD4 changes by clicking
on the button B1.
6. The software demonstration and the several software examples that allow the user to
use the Nucleo features, are available at the www.st.com/stm32nucleo webpage.
7. Develop an application using the available examples.

6 Hardware layout and configuration
The STM32 Nucleo-64-P board is designed around the STM32 microcontrollers in a
64-pins LQFP package.
Figure 3 illustrates the connection between the STM32 and the peripherals (ST-LINK/V2-1,
push-buttons, LEDs, ARDUINO® Uno V3 connector, and ST morpho connectors).
Figure 4 and Figure 5 show the location of these features on the STM32 Nucleo-64-P
board.
The mechanical dimensions of the board are shown in Figure 6.

6.2.1 Default board configuration
By default the STM32 Nucleo-64-P board is delivered with the external SMPS 1.1 V enabled
and VDD@3.3 V. It is possible to set the board for VDD@1.8 V. Before switching to 1.8 V, the
user must check that the extension module and the external shields connected to the
Nucleo-64-P board are 1.8 V compatible.
The default jumper configuration and VDD@1.8 V setting are shown in Table 4.

6.3 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 VIN, E5V, and 3.3 V on the CN5 ST morpho
connector, or by VIN and 3.3 V on the CN8 ARDUINO® connector.
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
CN5 pin 15, and NRST CN5 pin 14, at the 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 on the
STM32 Nucleo-64-P board.
For information about debugging and programming features, refer to the ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32 user manual (UM1075) at the www.st.com
website.
The changes versus the ST-LINK/V2 version are listed below.
New features supported on ST-LINK/V2-1 are:
USB software reenumeration
Virtual COM port interface on USB
Mass storage interface on USB
USB power management request for more than 100mA current on USB
The following features are no more supported on ST-LINK/V2-1:
SWIM interface
Application voltage lower than 3 V (need to add level shifter to support it)

The embedded ST-LINK/V2-1 can be used in two different ways according to the jumper
configuration (refer to Table 5):
Program/debug the STM32 on board,
Program/debug an STM32 in an external application board using a cable connected to
the SWD connector.
6.4.1 Drivers
Before connecting the STM32 Nucleo-64-P board to a Windows® PC (XP, 7, 8, and 10)
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 the USB composite device, as shown in Figure 7.
Figure 7. USB composite device
6.4.2 ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the 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.

6.4.3 Using the ST-LINK/V2-1 to program/debug the STM32
To program the STM32, place the two jumpers marked in red on the CN2 connector, as
shown in Figure 8. Do not use the SWD connector to avoid disturbing the communication
with the STM32 microcontroller of the Nucleo-64-P board.
Figure 8. ST-LINK debugger: jumper configuration for on-board MCU
6.4.4 Using the ST-LINK/V2-1 to program/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 CN2, as shown in Figure 9, and connect the
application to the SWD debug connector according to Table 6.
Note: JP4 NRST (target STM32 RESET) must be OFF when CN3 pin 5 is used in an external
application.

6.5 power supply and power selection
6.5.1 External power supply input
Several DC power supplies can power the STM32 Nucleo-64-P board. It is possible to
supply the STM32 Nucleo-64-P board with any of the following sources:
5V_ST_LINK from the ST-LINK USB connector
VIN (7 V-12 V) from ARDUINO® connector or ST morpho connector
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, a power supply unit or a piece of auxiliary
equipment complying with the EN-60950-1: 2006+A11/2009 standard, which must be safety
extra-low voltage (SELV) with limited power capability, must power the Discovery kit.
The power supply capabilities are shown in Table 7.
5V_ST_LINK is a DC power with limitations from the ST-LINK USB connector (USB type
Micro-B connector of ST-LINK/V2-1). In this case, the JP5 jumper must be on pins 1 and 2
to select the 5V_STL power source on the JP5 silkscreen. 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,
