STM32 Nucleo-64 boards (MB1360)

Introduction

The STM32 Nucleo-64 boards, based on the MB1360 reference board (NUCLEO-G070RB,

NUCLEO-G071RB, and NUCLEO-G0B1RE order codes) provide an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontroller, which provide various combinations of performance, power consumption, and features.

ARDUINO ® Uno V3 connectivity and ST morpho headers provide easy means of expanding the functionality of the Nucleo open development platform with a wide choice of specialized shields.

The STM32 Nucleo-64 boards do not require any separate probe, as they integrate the

ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64 boards come with the comprehensive free STM32 software libraries and examples that are available with the

STM32CubeG0 MCU Package.

The STM32 Nucleo-64 board is a low-cost and easy-to-use development kit to quickly evaluate and start development with an STM32 microcontroller in the QFP64 package. To start using this board, follow the steps below:

1.

Check the jumper position on the board, CN4 (STLK) on [1-2], [3-4], JP2 (PWR) on

[1-2], JP3 (IDD) on.

2. For correct identification of all device interfaces from the host PC, install the Nucleo

USB driver available on the www.st.com/stm32nucleo web page, before connecting the board.

3. To power the board, connect the STM32 Nucleo-64 board to a PC with a USB Type-A or USB Type-C ® to Micro-B cable through the CN2 USB connector. As a result, the green LED LD3 (PWR) lights up, LD1 (COM) blinks.

4. Press user button B1 (blue).

5. Observe that the blinking frequency of the three green LED LD4 changes, by clicking on the button B1.

6. The demonstration software and several software examples that allow the user to use the Nucleo features are available at www.st.com/stm32nucleo.

The STM32 Nucleo-64 board is divided into two parts: the ST-LINK part and the target MCU part. ST-LINK part PCB is cuttable to reduce board size. In this case, the rest target MCU part is only powered by VIN, E5V, and 3.3V on CN7 morpho connectors, or VIN and 3.3V on

CN6 ARDUINO ® connector. And it is still possible to use the ST-LINK part to program the main MCU using wires between CN7 and SWD signals available on morpho connectors.

Hardware layout and configuration UM2324

The ST-LINK/V2-1 programming and debugging tool is integrated into the Nucleo.

Compared to ST-LINK/V2 the changes are listed below.

The new features supported on ST-LINK/V2-1:

• USB software re-enumeration

• Virtual COM port interface on USB

• Mass storage interface on USB

• Registers R/W interface on USB (Not available on Nucleo)

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

The features no more supported on ST-LINK/V2-1:

• SWIM interface

• Minimum application voltage supported by Nucleo limited to 3V

• Standalone version doesn't exist (only Nucleo and future discovery support V2-1)

For all general information concerning debugging and programming features common between V2 and V2-1 refer to ST-LINK/V2 user manual (UM1075).

The embedded ST-LINK/V2-1 is usable in two different ways according to the jumper states

6.4.1 Drivers

Before connecting the STM32 Nucleo-64 board to a Windows

®

PC (7, 8, or 10) through

USB, install the driver for the ST-LINK/V2-1 that is available at the www.st.com

website.

Note:

In case the STM32 Nucleo-64 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 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 6 .

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 board. The latest version of this firmware is available at the www.st.com

website.

Using the ST-LINK/V2-1 to program/debug the STM32 on board

To program the STM32 on board, simply plug in the two jumpers on CN4, as shown in

Figure 7 in pink, but do not use the CN11 connector as that may disturb communication with

the STM32 microcontroller of the Nucleo.

6.5 Power supply and power selection

Note:

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

• 5V_USB_STLK 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_CHG from the ST-LINK USB connector

• 3.3 V on ARDUINO ® connector or ST morpho connector

If an external 5 V DC power source is used, the Nucleo board must be powered by a power supply unit or by auxiliary equipment complying with the standard EN-60950-1:

2006+A11/2009 and must be safety extra-low voltage (SELV) with limited power capability.

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 JP2 jumper must be on pins 1 and 2 to select the STLK power source on the JP2 silkscreen. This is the default setting. If the

USB enumeration succeeds, the STLK power is enabled, by asserting the PWR_ENn signal

(from STM32F103CBT6). This pin is connected to an STMPS2141STR power switch, 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 board and its shield are powerable from the CN2 ST-LINK USB connector, but only the 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, the

STM32 Nucleo-64 board requires 500 mA of current from the host PC. If the host can provide the required power, the enumeration ends by a ‘SetConfiguration’ command and then, the power transistor STMPS2141STR is switched ON, the green LED LD3 is turned

ON, thus the STM32 Nucleo-64 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 STMPS2141STR 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.

• 5V: The 5V (CN6 pin 5 or CN7 pin 18) is usable as an output power supply for an

ARDUINO ® shield or an extension board when the STM32 Nucleo-64 board is powered by USB, VIN, or E5V. In this case, the maximum current allowed is shown in

Table 7

.

• 3.3V: on CN6 pin 4 or CN7 pin 16 is usable as power supply output. The current is limited by the maximum current capability of the regulator U6 (LDL112PV33R from

STMicroelectronics). In this condition, the maximum consumption of the STM32

Nucleo-64 board and the connected shield must be less than 500 mA.

22/43

ST-LINK

VIN or E5V is usable as an external power supply in case the current consumption of the

STM32 Nucleo-64 board and its extension boards exceed the allowed current on the USB.

In such a 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:

UM2324 Rev 4

UM2324 Hardware layout and configuration

1.

Connect jumper JP2 between pins 3 and 4 for VIN or pins 5 and 6 for E5V,

2. Connect the external power source to VIN or E5V,

3. Power ON the external power supply 7 V < VIN < 12 V to VIN, or 5 V for E5V,

4. Check that the green LED LD3 is turned ON,

5. Connect the PC to the CN2 USB connector.

If this sequence is not respected, the board may be powered by VBUS first from the ST-

LINK, 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 SB15 must be OFF): this request is rejectable and the enumeration does not succeed if the PC does not provide such current, consequently, the board is not power supplied (LED LD3 remains OFF).

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 board

LSE: OSC 32 kHz clock supply

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

1.

LSE on-board X2 crystal (Default configuration). Refer to crystal design guide for

STM8S, STM8A, and STM32 microcontrollers application note (AN2867) for crystal design guide for STM32 microcontrollers. It is recommended to use NX3215SA manufactured by NDK (32.768 kHz, 6 pF, 20 ppm).

CN7 connector. The following configuration is needed:

– SB23 ON

– R31 and R32 removed

3. LSE not used: PC14 and PC15 are used as GPIOs instead of low-speed clocks.

The following configuration is needed:

– SB23 and SB24 ON

– R31 and R32 removed

6.7.2 HSE: OSC 8 MHz clock supply

UM2324

There are four ways to configure the pins corresponding to the external high-speed clock

(HSE):

• HSE not used (default): PF0 and PF1 are used as GPIOs instead of clocks. The configuration must be:

– SB25 and SB27 ON

– SB17 (MCO) OFF

– R33 and R34 OFF

• MCO from ST-LINK: MCO output of ST-LINK is used as an input clock. This frequency cannot be changed, it is fixed at 8 MHz and connected to the PF0-OSC_IN of the

STM32 microcontroller. The configuration must be:

– SB17 ON

– SB25 and SB27 OFF

– R33 and R34 OFF

• HSE on-board oscillator from X3 crystal (not provided): for typical frequencies, capacitors, and resistors, refer to the STM32 microcontroller datasheet and the

Oscillator design guide for STM8S, STM8A, and STM32 microcontrollers application note (AN2867) for the oscillator design guide. The X3 crystal has the following characteristics: 8 MHz, 8 pF, 20 ppm. It is recommended to use NX3225GD-8.000M-

EXS00A-CG04874 manufactured by NIHON DEMPA KOGYO CO., LTD. The configuration must be:

– SB25 and SB27 OFF

– R33 and R34 soldered

– C24 and C25 soldered with 10 pF capacitors

– SB17 OFF

• Oscillator from external PF0: from an external oscillator through pin 29 of the CN7 connector. The configuration must be:

– SB25 ON

– SB17 OFF

– R33 and R34 removed

The reset signal of the STM32 Nucleo-64 board is active low and the reset sources include:

• B2 Reset button

• Embedded ST-LINK/V2-1

• Pin 3 of the CN6 ARDUINO ® Uno V3 connector

• Pin 14 of the CN7 ST morpho connector

The UART2 interface of the STM32 is connectible to:

• The ST-LINK/V2-1 MCU

• The ST morpho connector (CN10 pin 6 and pin 34)

6.10 LEDs

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

1.

LD1 COM: LD1 is a bi-colored LED. the 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 and off: at power-on before USB initialization

– Fast blinking red and off: after the first correct communication between the PC and the STLINK/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 and green: during communication with STM32

– Green on: communication well ended

– Orange on: communication ended with failure

2. LD2: 5V_USB_CHG: this red LED is ON when overcurrent is detected on USB VBUS.

The LED gives the information that more than 500 mA is requested on VBUS. In this case, it is recommended to supply the board with E5V, VIN, or in USB_CHARGER mode.

3. LD3: 5V_PWR: this green LED is ON when the STM32 Nucleo-64 board is powered by a 5 V source.

4. LD4 USER: this green LED is a user LED connected to ARDUINO

®

signal D13 corresponding to STM32 I/O PA5. 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 V. LD4 consumption does not impact the VDD STM32 power measurement, since LD4 is isolated from it.

6.11 Push-buttons

• B1 USER: User and Wake-Up button connected to the I/O PC13 (Pin 3) of the STM32

Microcontroller.

• B2 RESET: Pushbutton connected to NRST is used to RESET the STM32

Microcontroller.

The blue and black plastic hats placed on these pushbuttons are removable if necessary when a shield or an application board is plugged on top of Nucleo. This avoids pressure on the buttons and consequently a possible permanent Target MCU RESET.

UM2324

The stickers located on the top or bottom side of the PCB provide product information:

• Product order code and product identification for the first sticker

• Board reference with revision, and serial number for the second sticker

On the first sticker, the first line provides the product order code, and the second line the product identification.

On the second sticker, the first 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 line shows the board serial number used for traceability.

Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as 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 designs or in production.

“E” or “ES” marking examples of location:

• On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the STM32 datasheet “Package information” paragraph at the www.st.com
