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.

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, same I/O level as V

DD_MCU

).

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 ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32 User manual (UM1075) at the www.st.com website.

The changes versus ST-LINK/V2 version are listed below.

New features supported on ST-LINK/V2-1 are:

• USB software re-enumeration

• Virtual COM port interface on USB

• Mass storage interface on USB

• USB power management request for more than 100mA power 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)

6.4.1 Drivers

Note:

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.

It is recommended to proceed by using 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 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.

Note:

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 .

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

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

20/50 UM2206 Rev 5

UM2206 Hardware layout and configuration 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 mA to the board at that time. During the USB enumeration,

STM32 Nucleo-64-P board requires 500 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.

Caution: Solder bridge SB9 can be used to bypass the USB power protection ST890. ( This is not an

ST recommended setting ). SB9 can be set in case the board is powered by the USB of the

PC and maximum current consumption on 5V_STLINK does not exceed 100 mA

(including extension board or ARDUINO

ARDUINO ® shield or an extension board, when the STM32 Nucleo-64-P board is powered by USB, V

IN

or E5V. In this case the maximum current allowed is shown in Table 7 .

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.

IN

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 V

IN

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 V

or pins 5 and 6 for E5V

2. Be sure that SB9 is removed

3. Connect the external power source to V

BUS 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).

6.7.1

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.

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 oscillator design guide for STM32 microcontrollers. It is recommended to use NX3215SA manufactured by NDK (32.768 kHz, 6 pF, 20 ppm).

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

RESET.

Note:

The jumper JP6, labeled IDD , is used to measure the STM32 microcontroller, the level shifter and the SMPS consumptions (depending on solder-bridge configuration), by removing the jumper and by connecting a multimeter:

• Jumper ON: directly powered (default)

• Jumper OFF: a multimeter or an external 3.3 V power source must be connected to measure the consumption

STM32 Nucleo-64-P board information

8 STM32 Nucleo-64-P board information

UM2206

The sticker located on the top or bottom side of the PCB shows the information about product identification such as board reference, revision, and serial number.

The first identification line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board reference, “Variant” (optional) identifies the mounting variant when several exist,

"y" is the PCB revision and "zz" is the assembly revision, for example B01.

The second identification line is the board serial number used for traceability.

Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are not ready to be used as a reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference design or in production.

"E" or "ES" marking examples of location:

• On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the section “Package characteristics” of the STM32 datasheet at www.st.com

).

• Next to the evaluation tool ordering part number, that is stuck or silk-screen printed on the board.

These boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
