7.3 Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated on the 32F723EDISCOVERY board. Compared to ST-LINK/V2 the changes are listed below.

The 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

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

• SWIM interface

• Application voltage lower than 3V

For general information concerning the debugging and programming features that are common to both versions V2 and V2-1, refer to ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32 User manual (UM1075).

7.3.1 Drivers

Before connecting the 32F723EDISCOVERY board to a Windows® 7, Windows® 8 or Windows® XP PC via USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the www.st.com website.

In case the 32F723EDISCOVERY board is connected to the PC before installing the driver, the PC device manager may report some 32F723EDISCOVERY board interfaces as “Unknown”. To recover from this situation, after installing the dedicated driver, the association of “Unknown” USB devices found on the 32F723EDISCOVERY board to this dedicated driver, must be manually updated in the device manager.

Note: It is recommended to proceed using USB Composite Device, as shown in Figure 7.

7.3.2 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 life time of the ST-LINK/V2-1 product (for example a new functionality, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the 32F723EDISCOVERY board and periodically, to stay up-to-date with the latest firmware version.

7.4 Power supply

The 32F723EDISCOVERY board is designed to be powered from a 5 V DC power source. It is possible to configure the 32F723EDISCOVERY board to use any of the sources described in the following Table 2.

Note: 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.

7.4.1 Supplying the board through the ST-LINK USB port (default setting)

To power the 32F723EDISCOVERY board in this way the USB host (PC) gets connected with the ST-LINK USB port through a USB Type-A to Micro-B cable

5 V DC power is provided by VBUS from the USB type Micro-B connector (CN1) of ST-LINK/V2-1 (USB 5 V power source on silkscreen “ST-LINK”, see Figure 8). If the USB enumeration succeeds (as explained below), the ST-LINK 5 V link power is enabled by asserting the PWR_ENn signal. This pin is connected to U1, 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 the board (current demand exceeding 700 mA).

The 32F723EDISCOVERY board can be powered from the ST-LINK USB connector CN1 (STLINK), but only the STM32F103CBT6 (U2) is powered before USB enumeration, because the host PC only provides 100 mA to the board at that time. During the USB enumeration, the 32F723EDISCOVERY board asks for the 500 mA power to the host PC. Two events can happen:

• If the host is able to provide the required power, the enumeration finishes by a “SetConfiguration” command and then, the power transistor ST890 is switched ON, the

16/59 DocID029990 Rev 2

red LED LD2 is turned ON, thus the 32F723EDISCOVERY board consumes maximum 500 mA current, but no more.

• If the host is not able to provide the requested current, the enumeration fails. Therefore the ST890 remains OFF and the STM32 part including the extension board is not powered. As a consequence the red LED LD2 remains turned OFF. In this case it is mandatory to use an external power supply.

Figure 8. CN8 (ST-LINK)

Note: In case the 32F723EDISCOVERY board is powered by a USB charger, there is no USB enumeration, so the led LD2 remains set to OFF permanently and the board is not powered. Only in this specific case, the resistor R5 needs to be soldered, to allow the board to be powered anyway.

The LED LD2 is lit when the 32F723EDISCOVERY board is powered by the 5 V correctly.

Caution: Do not connect a PC to ST-LINK (CN1) when R5 is soldered. The PC may be damaged or the board not powered correctly.

7.4.2 Supplying the board through a charger connected to ST-LINK

The 5 V DC power charger is connected to USB STLINK (CN1). In this case if the 32F723EDISCOVERY board is powered by an external USB charger then the debug is not available. If the PC is connected instead of the charger, then the limitation is no more effective and the PC could be damaged (5 V power source on silkscreen “USB_STLINK” see Figure 9).

7.4.3 Supplying the board from E5V (CN3 or CN12)

Figure 10. CN8 (External 5V supply)

From E5V: 5V DC power adapter connected to CN3

In this case, the 32F723EDISCOVERY board must be powered by a power supply unit or by an auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009 connected to CN3, and must be Safety Extra Low Voltage (SELV) with limited power capability (5 V power source on silkscreen “E5V” see Figure 10).

From E5V: 7-12V DC power from CN12 (VIN)

7-12 V DC power supply is provided by an Arduino Uno V3 compatible shield connected to CN11, CN12, CN13 and CN15 connectors.

This 7-12 V voltage (VIN) is then converted to 5 V by a LDO (U11).

Finally, the user must fit the jumper on "E5V" position on CN8 connector, to select this LDO output (E5V) as main power supply for the board (see Figure 10).


18/59 DocID029990 Rev 2

7.4.4 Supplying the board from an external power supply through USB HS

A 5 V DC external power supply is connected to USB OTG HS Micro-AB connector CN19 (5 V power source on silkscreen “USB_HS”, refer to Figure 11).

Figure 11. CN8 (USB_HS)

7.4.5 Supplying the board from an external power supply through USB FS

A 5 V DC external power supply is connected to USB OTG FS Micro-AB connector CN18 (5 V power source on silkscreen “USB_FS”, see Figure 12).

Figure 12. CN8 (USB_FS)

7.5 Programming/debugging when the power supply is not from ST-LINK

It is mandatory to power the board first using CN3 (E5V) or CN12 (VIN) or CN18 (USB FS) or CN19 (USB_HS), then connecting the USB cable to the PC. Proceeding this way ensures that the enumeration succeeds thanks to the external power source.

The following power sequence procedure must be respected:

DocID029990 Rev 2 19/59


58

1. Connect the jumper CN8 on (E5V) or (USB_HS) or (USB_FS)

2. Connect the external power source to CN3 or CN12 or CN18 or CN19

3. Check that the red LED LD2 is turned ON

4. Connect the PC to USB connector CN1

If this order is not respected, the 32F723EDISCOVERY Discovery board may be powered by VBUS first from ST-LINK and the following risks may be encountered:

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

2. 500 mA is requested at the enumeration: if the PC cannot provide such current, there is a risk that the request is rejected and the enumeration does not succeed.

7.6 Clock sources

Up to 2 clock sources as described below:

• X2, 25 MHz oscillator for STM32F723IEK6 microcontroller.

• X3, 32 KHz crystal for STM32F723IEK6 embedded RTC

7.7 Reset sources

The reset signal of the 32F723EDISCOVERY board is active low and the reset sources include:

• Reset button B2

• Arduino Uno V3 shield board from CN12

• Embedded ST-LINK/V2-1

7.8 Audio

An audio codec WM8994ECS/R from CIRRUS with 4 DACs and 2ADCs is connected to SAI interface of STM32F723IEK6. It communicates with STM32F723IEK6 via I2C bus:

• The analog line input is connected to ADC of WM8994ECS/R through blue audio jack CN4

• The analog line output is connected to DAC of WM8994ECS/R via green audio jack CN5

• Two external speakers can be connected to WM8994ECS/R via CN10 for left speaker and CN7 for right speaker

• Four digital microphones (ST-MEMS microphone) MP34DT01TR are on 32F723EDISCOVERY board. They are connected to input digital microphones of WM8994ECS/R


20/59 DocID029990 Rev 2

7.9 USB OTG HS

The 32F723EDISCOVERY board supports USB OTG high-speed communication via a USB Micro-AB connector.

A USB power switch is also connected on VBUS and provides power to CN19. The green LED LD8 is lit in one of these cases:

• Power switch is ON and 32F723EDISCOVERY board works as a USB host

• VBUS is powered by another USB host when 32F723EDISCOVERY board works as a USB device.

The red LED LD7 is lit when an overcurrent occurs.

Note:1 When the 32F723EDISCOVERY board is powered by the ST-LINK then the OTG function can provide up to 100 mA.

Note:2 When the 32F723EDISCOVERY board is powered by an external power supply then the OTG function can provide more than 100 mA, according to the external power supply capability.

Note:3 When the 32F723EDISCOVERY board is powered by an external power supply through USB HS connector (CN19), in device mode, do not use a PC as power source (see Section 7.4.4.)

7.10 USB OTG FS

The 32F723EDISCOVERY board supports USB OTG full speed communication via a USB Micro-AB connector.

A USB power switch is also connected on VBUS and provides power to CN18. The green LED LD9 is lit in one of these cases:

• Power switch is ON and the 32F723EDISCOVERY board works as a USB host

• VBUS is powered by another USB host when the 32F723EDISCOVERY board works as a USB device.

The red LED LD10 is lit when an overcurrent occurs.

Note:1 When the 32F723EDISCOVERY board is powered by the ST-LINK then the OTG function provides up to 100 mA.

Note:2 When the 32F723EDISCOVERY board is powered by an external power supply then the OTG function provides more than 100 mA, according to the external power supply capability.

Note:3 When the 32F723EDISCOVERY board is powered by an external power supply through USB FS connector (CN18), in device mode, do not use a PC as power source (see Section 7.4.5)

Note:4 On "Rev.C" boards (MB1260 C01), for device mode, the path in ESD protection U22 from USB data pins causes a raised voltage on USB VBUS after disconnection. As a result the device disconnect event is not detected and so BCD capability cannot be used.

Note:5 On "Rev.D" boards (MB1260 D01), no more limitation: device disconnect event is detected and BCD capability can be used.

Appendix C PMOD and STMod+ schematic table

The Table 18 gives the description of the signals available on the STMod+ connector. It also shows which signal is shared with other board connectors (such as PMOD or Arduino Uno V3). A switch controlled by software is present to select which function is used (using PI10 and PH15 PIOs). Analog signals are in brackets [xxx]. The I2C bus is shared with the Arduino Uno V3 connectors. It is recommended to check the device slave address when adding it to the bus. Refer to the following list of acronyms before reading the Table 18:

• RTS7 stands for USART7_RTS

• ADC2.4 stands for ADC_2_IN4

• T8.4 stands for TIM_8_CH4

• MOSI5 stands for SPI_5_MOSI
