3 Product marking
Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are 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 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 information" of the STM32 datasheet at www.st.com).
•Next to the evaluation tool ordering part number, that is stuck or silkscreen printed on
the board

6.3 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the
32F769IDISCOVERY discovery 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 3 V
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).
6.3.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which, for Windows® XP, 7 and 8, is
available at the www.st.com website.
In case the 32F769IDISCOVERY discovery board is connected to the PC before the driver
is installed, some 32F769IDISCOVERY interfaces may be declared as "unknown" in the PC
device manager. In this case the user must install the driver files, and update the driver of
the connected device from the device manager.
Note:Prefer using the "USB Composite Device" handle for a full recovery.

6.3.2 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 new functionalities, bug fixes, support for new microcontroller families), it is
recommended to visit the www.st.com website before starting to use the
32F769IDISCOVERY discovery board and periodically, to stay up-to-date with the latest
firmware version.

6.4 Power supply
The 32F769IDISCOVERY discovery board is designed to be powered by the 5 V DC power
supply. It is possible to configure the discovery board to use any of the following five sources
for the power supply:
•5 V DC power adapter connected to JP1 (Ext 5 V). In this case, the
32F769IDISCOVERY 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 (5 V power
source on the silkscreen of JP1 (Ext 5 V). See Figure 9:
Figure 9. CN3 (ext5V) from JP1 (Ext 5 V)
•7-12 V DC power from CN11 pin named Vin on silkscreen, the extension connectors for
Arduino UNO shields or daughterboards (5 V power source on silkscreen of JP1 (Ext
5 V)). The input current capability is linked to the input voltage (see Figure 10):
–800 mA input current when Vin=7 V
–450 mA input current when 7 V<Vin (< or =) 9 V
–250 mA input current when 9 V<Vin (< or =) 12 V

•5 V DC power charger connected to USB ST-LINK (CN16). In this case, if the
32F769IDISCOVERY discovery board is powered by an external USB charger then the
debug features are not available. If the board is connected to the PC instead, the
limitation is no more effective with high risk to damage the PC (5 V power source on
silkscreen of CN3 (chgr). See Figure 11:
Figure 11. CN3 (chgr)
•48 V DC power from RJ45 connector CN10 (Ethernet). In this case, the on-board
module PoE (Power over Ethernet) generates the 5 V and it is able to provide up to
600 mA. This module is a Powered Device complying with the standard IEEE802.3af,
class 1 / 2. The external power supply must be fully IEEE 802.3af compliant (5 V power
source on silkscreen of CN3 (poe5V). See Figure 12:
Figure 12. CN3 (poe5V)
•5 V DC power with limitation from CN16, the USB type micro-B connector of
ST-LINK/V2-1 (USB 5 V power source on silkscreen of CN3 (stlk)). It is the default
setting. 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 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 (more than 700 mA).
See Figure 13.
The 32F769IDISCOVERY discovery board can be powered from the ST-LINK USB
connector CN16 (stlk), but only the ST-LINK circuit has the power before the USB
enumeration, because the host PC only provides 100 mA to the board at that time. During
the USB enumeration, the 32F769IDISCOVERY discovery board asks for the 500 mA
power to the host PC. 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
16/55DocID029085 Rev 2
Page 17
UM2033Hardware layout and configuration
ON, the red LED LD6 is turned ON, thus the 32F769IDISCOVERY discovery board can
consume 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 LD6
remains turned OFF. In this case it is mandatory to use an external power supply.
Figure 13. CN3 (stlk)
Note:In case the 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 R138 needs to be soldered, to allow the board to be powered anyway.
The LED LD6 is lit when the 32F769IDISCOVERY discovery board is powered by the 5 V
correctly.
Caution:Do not connect the PC to the ST-LINK (CN16) when R138 is soldered. The PC may be
damaged or the board not powered correctly.
•5 V DC power with 500 mA limitation from CN15, the USB OTG HS micro-AB
connector (5 V power source on silkscreen of CN3 (usbhs)). See Figure 14:
Figure 14. CN3 (usbhs)

6.5 Programming/debugging when the power supply is not from
ST-LINK (5 V link)
It is mandatory to power the board first using JP1 (Ext 5 V) or CN11 (Vin) or CN10
(Ethernet) or CN15 (usbhs), 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:
1.Connect the jumper CN3 on (ext5V) or (usbhs) or (poe5V)
2. Connect the external power source to JP1 or CN11 or CN10 or CN15
3. Check the red LED LD2 is turned ON
4. Connect the PC to USB connector CN16
If this order is not respected, the board may be powered first by VBUS from the 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 the PC. As a consequence the board is not powered correctly.
2. 500 mA is requested at the enumeration: in this case there is a risk that the request is
rejected and the enumeration does not succeed if the PC cannot provide such current.
6.6 Clock sources
Up to three clock sources are available, as described below:
•X1, 24MHz oscillator for USB OTG HS PHY
•X2, 25MHz oscillator for the STM32F769NIH6 microcontroller and Ethernet PHY
•X3, 32KHz crystal for the STM32F769NIH6 embedded RTC
6.7 Reset sources
The reset signal of the 32F769IDISCOVERY discovery board is active low and the reset
sources are:

6.8 Audio
An audio codec WM8994ECS/R from CIRRUS with 4 DACs and 2 ADCs is connected to the
SAI interface of the STM32F769NIH6. It communicates with the STM32F769NIH6 via I
bus shared with the touch panel of the LCD DSI:
•The analog line input is connected to ADC of WM8994ECS/R through
the audio jack CN6.
•The analog line output is connected to DAC of WM8994ECS/R
via the audio jack CN7.
•Two external speakers can be connected to WM8994ECS/R via
the JP2 for the left speaker and JP3 for the right speaker.

32F769IDISCOVERY discovery board. They are connected to the input digital
microphones of the STM32F769NIH6 and are managed by the DFSDM functionality.
•One coaxial connector CN12 is implemented on the 32F769IDISCOVERY to receive
an external audio data compatible with SPDIF specification.
•One coaxial connector CN8 is implemented on the 32F769IDISCOVERY to output
external audio data compatible with SPDIF specification.
6.9 USB OTG HS
32F769IDISCOVERY discovery board supports USB OTG high-speed communication via a
USB micro-AB connector and a USB high-speed PHY USB3320C-EZK from MICROCHIP
for high-speed function.
The discovery board can be powered by the USB connectors at 5 V DC with 500 mA current
limitation.
A USB power switch is also connected on VBUS and provides power to CN15. The green
LED LD5 is lit in one of these cases:
•Power switch is ON and 32F769IDISCOVERY works as a USB host
•VBUS is powered by another USB host when 32F769IDISCOVERY works as a USB
device
The red LED LD4 is lit when an overcurrent occurs.
Note:32F769IDISCOVERY discovery board should be powered by an external power supply
when using OTG function.
