5.1 Embedded ST-LINK/V2-1

The ST-LINK/V2-1 pr ogramming and debugging tool is integrated on the STM32469I­DISCO board. Compared to ST-LINK/V2 the new features supported on ST-LINK/V2-1 are:

• USB sof tware re-enumeration

• Virtual com port interface on USB

• Mass storage interface on USB

• USB power mana gement request for more than 100mA power on USB

This feature is no more supported on ST-LINK/V2-1:

• SWIM interface
For all general information concerning debugging and programming features common

between V2 and V2-1 please refer to ST-LINK/V2 User Manual UM1075.

5.1.1 Drivers

Before connecting STM32F469I-DISCO 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

www.st.com.

In case the STM32F469I-DISCO board is connected to the PC before installing the driver,
the Windows device manager may report some USB devices fou nd on STM32F469I-DISCO
as “Unknown”. To recover from this situation, after installing the dedicated driver
downloaded from www.st.com, the association of “Unknown” USB devices found on
STM32F469I-DISCO to this dedicated driver must be updated in the device manager
manually. It is recommended to proceed using USB Composite Device line, as shown in
figure below

Note: Prefer using the “USB Composite Device” handle for a full re co ve ry.

5.1.2 ST-LINK/V2-1 firmware upgrade

ST-LINK/V2-1 facility for debug and flashing of the target microcontroller STM32F469NIH6
is integrated on STM32F469I-DISCO board. For its own operation, ST-LINK/V2-1 employs a
dedicated MCU with Flash memory. Its firmware determines ST-LINK/V2-1 functionality and
performance. The firmware may evolve durin g the life span of STM32 F46 9I-DISCO to
include new functionality, fix bugs or support new target microcontroller families. It is

Hardware layout and configuration UM1932

12/40 DocID028183 Rev 1

therefore recommended to keep ST-LINK/V2-1 firmware up to date. The latest version is
available from www.st.com. ST-LINK/V2-1 supports a mechanism that allows flashing its
dedicated MCU via the USB interface on the hosting board, here STM3 2F469I- DISCO. The
whole process is controlled from a Windows PC application also available from www.st.com.

5.2 Power supply

5.2.1 Power supply sources

STM32F469I-DISCO board is designed to be powered by the following sources:

• 5 V DC from the ST-LINK/V2-1 USB connector CN1 with 500 mA current limitation.
Power mechanism of the board supplied by the USB ST-LINK/V2-1 is explained below
(Section 5.2.2: Supplying the board through ST-LINK/V2-1 USB port). Pins 3 and 4 of
jumper JP2 should be closed by placing a jumper in location called STLK on silkscreen
of the board. Jumper JP5 should be closed.The red LED LD5 is lighted on to confirm
the presence of +5 V voltage.

• 5 V DC from the user USB FS connector CN13. Pins 5 and 6 of jumper JP2 should be
closed by placing a jumper in location called USB on silkscreen of the board. Jumper
JP5 should be closed. The red LED LD5 is lighted on to confirm the presence of +5 V
voltage.

• 6 V to 9 V DC from VIN pin of Arduino

™

compatible connector CN6. The voltage must
be limited to 9 V to keep the temperature of the regulator U10 within it s thermal safe
area. Pins 1 and 2 of jumper JP2 should be closed by placing a jumper in location
called E5V on silkscreen of the board. Jumper JP5 should be closed. Th e red LED LD5
is lighted on to confirm the presence of +5 V voltage.

• An external +3.3 V DC source connected to pin 4 of Arduino

™

compatible connector
CN6. The user should carefully check that the voltage of the external supply is +3.3 V
before connecting to pin 4 of CN6, since this voltage is directly a pplied to supply pins of
the microcontroller. Jumper JP5 should be closed, and it is mandatory to remove the
solder bridge SB8, to avoid applying a reverse current to the output of regulator U7.
The LED LD5 is not lighted because it is not connected to +3.3 V supply. No jumper in
JP2. Using this power scheme, the USB host mode and LCD backlight do not work
because the 5 V is not available.

• An external +3.3 V DC source connected to pin 1 of extension connector CN12.The
user should carefully check that the voltage of the external supply is +3.3 V before
connecting to pin 1 of CN12, since this voltage is directly applied to supply pins of the
microcontroller. Jumper JP5 should be closed, and it is mandatory to remove the solder
bridge SB8 to avoid to apply a reverse current to the output of regulator U7. The LED
LD5 is not lighted because not connected to +3.3 V supply. No jumper in JP2. Using
this power scheme, the USB host mode and LCD backlight do not work because the
5 V is not available.

To power the STM324F69I-DISCO board in this way, the USB host (a PC) gets connected
with the STM324F69I-DISCO board via USB cable to ST-LINK/V2-1 connector.

In the first step, only the ST-LINK part U3 is powered by the PC. In fact, before USB
enumeration the host PC provides only 100mA to the board at that time. STM324F69I­DISCO board requests for 500mA power to the host PC. If the host is able to provide the

39

required power , the enumeration finishes by a “SetConfiguration” command and then, the
power switch ST890 U4 is switched ON, the red LED LD5 is turned ON, thus the board can
consume no more than 500mA. If the host is not able to provide such requested current, the
enumeration fails. Therefore the ST890 U4 remains OFF and the board will not be powered.
As a consequence the red LED LD5 remains turned OFF . In this case it is mandatory to use
another power supply source.

To do this, it is important to power the board before connecting it with the host PC, which
requires the following sequence to be respected:

1. Set the jumper in JP2 header in E5V position.

2. Connect an external power source to VIN pin 8 of Arduino connector CN6.

3. Check the red LED LD5 is turned on.

4. Connect host PC to USB connector CN1.

The ST890 power switch protects the USB port of the host against current demand
exceeding 600 mA, should a short-circuit occur on the board.

The STM32F469I-DISCO board can also be supplied from a USB power source not
supporting enumeration, such as a USB charger. In this particular case, the solder bridge
SB16 should be closed. ST-LINK/V2-1 turns the ST890 power switch U4 ON regardless of
enumeration procedure result and passes the power unconditionally to the board.

5.2.3 Measurement of current IDD drawn by the STM32F469NI

The jumper JP5 should be closed (default) to supply the STM32F469NI MCU. To measure
the current IDD drawn by the microcontroller STM32F469NIH6 only, remove the jumper JP5
and replace it by a multimeter.

5.2.4 Power related jumpers

The power supply is configured by setting the related jumpers JP2, JP5 and solder bridge
SB8 as described in Table 1: Power related jumpers.

Table 1. Power related jumpers

Solder bridge

Description

JP5

JP5 IDD is used to measure STM32 current consumption manually by multimeter.
Default setting: Closed by a jumper

SB8

By default SB8 is closed to power +3V3 from regulator U7.
If the board is powered by the pin 1 of extension connector CN12 or by the pin 4 of

the Arduino connector CN6, it is mandatory to open SB8 to avoid reverse current
injection in regulator U7.

(Default setting): SB8 closed

5.3 Clock source

5.3.1 HSE clock source

By default the HSE clock source of the STM32F469NIH6 is the 8 MHz crystal X2. In that
case, zero ohm R131 is soldered, solder bridge SB19 is open.

It is possible to replace the crystal X2 by the 8 MHz output MCO from the circuit ST­LINK/V2-1 U3. In that case, 100 ohms resistor R35 should be soldered, zero ohm R131
should be removed, solder bridge SB19 should be closed. C26 is not necessary and
remains not populated.

5.3.2 LSE clock source

The 32.768kHz crystal X3 is the clock source for the embedded RTC.

JP2

JP2 is used to select one of the five possible power supply sources.
To supply the board from the ST-LINK/V2-1 USB connector CN1, JP2 should be set

as shown to the right:

(Default Setting)

To supply the board from the User USB FS connector USB connector CN13, JP2
should be set as shown to the right:

To supply the board from the pin 8 VIN of the Arduino compatible connector CN6,
JP2 should be set as shown to the right:

To supply the board from pin1 of extension connector CN12 or from pin4 of the
Arduino compatible connector CN6, JP2 should be set as shown to the right (no
jumper):

5.4 Reset source

The reset signal of STM32F469I-DISCO board is low active and the reset sources include:

• Reset button B1, providing solder bridge SB1 is closed (default setting)

• Embedded ST-LINK/V2-1, providing solder bridge SB2 is closed (defau lt sett ing )

• Arduino

compatible connector CN6 pin 3

• Extension connector CN12 pin 4

5.5 Audio outputs

An audio DAC CS43L22 U5 from Cirrus Logic output s the au dio to a stereo head phon e jack
connector.

The digital audio interface SAI of STM32F469NIH6 is connected to the digital audio input
SDIN of the audio DAC. The STM32F469NIH6 controls the audio DAC via the I2C2 bus.
Note that I2C speed of the CS43L22 is 100 kHz max.

The PWM loudspeaker output SPKR_OUTA of the CS43L22 is available at pins 15 and 16
of the extension connector CN12. Each of the two terminals of the external loudspeaker
should be connected to pins 15 and 16 of CN2 respectively. Insure the terminals of the
loudspeaker are not connected to the ground.

The port PE3 STM32F469NIH6 enables the jack headphon e output and /or the loudspeaker
SPKR_OUT. Providing the audio DAC registers are properly set, it allows to power down the
loudspeaker and/or the headphone outputs.

The I2C address of the audio DAC is 0x94.

5.6 Digital microphones

Three STMicroelectronics MP34DT01TR MEMS digital microphones are available on the
discovery board STM32F469I-DISCO. Two microphones can be used simultaneously in
stereo mode using PDM mode. By default the microphones U2 and U6 are used and
connected to the DFSDM of the STM32F469I microcontroller (solder bridg es SB17 opened,
and SB18 closed). The PDM clock is generated at port PD13 while PDM data are received
by the microcontroller at port PD6.

Instead of using the pair of microphones U2 and U6, it is possible to use the pair of
microphones U2 and U1. To enable this possibility the solder bridge SB17 should be closed
and SB18 opened.

Solder bridges locations are shown in Figure 4: STM32F469I-DISCO top side layout .

5.7 USB OTG FS

An USB OTG full speed communication is available at connector CN13.
The STM32F469I-DISCO discovery board can be powered by the 5 V DC of this USB OTG

FS connection. When the STM32F469I-DISCO is USB host, it supplies the USB peripheral.
In this case the board must be supplied by any of the following sources: ST-LINK/V2-1 USB
connector CN1 or pin VIN of Arduino connector CN6. Refer to Section 5.2: Power supply for
more details on each supply source.

Hardware layout and configuration UM1932

16/40 DocID028183 Rev 1

The green LED LD8 will be lit in one of these cases:

• STM32F469I-DISCO works as an USB host and power switch U16 is switched ON.

• VBUS is powered by another USB host when STM32F469I-DISCO works as an USB

device.

Red LED LD9 will be lit when an over-current occurs.

5.8 MicroSD card

MicroSD card with 4 GB or more capacity can be inserted in the receptacle CN9. 4 bits of
the SDIO interface of the STM32F469NIH6 are used to communicate with the microSD
card. The card detection is read by the GPIO PG2: when a microSD card is inserted, the
logic level is 0, otherwise it is 1.

5.9 SDRAM

A 128-Mbit SDRAM Micron MT48LC4M32B2B5-6A is accessible with the FMC interface of
the microcontroller STM32F469NIH6. The data bus is 32 bits wide.

The SDRAM is composed of four banks of 32 Mbits selected by the address bits A14 and
A15.

Each of the four banks is organized as 4096 rows by 256 columns by 32 bits. Raw and
column addresses are pre-selected using the CAS and RAS signals of the FMC bus.

The SDRAM is selected by SDNE0 and can be addressed from 0xC0000000 to
0xC0FFFFFF.

5.10 Quad-SPI NOR Flash Memory

A 128-Mbit Quad-SPI NOR Flash memory (N25Q128A13EF840E from MICRON) is
connected to Quad-SPI interface of the STM32F469NIH6 microcontroller.

5.11 Virtual ComPort

The serial interface USART3 is directly available as a Virtual ComPort of the PC connected
to the ST-LINK/V2-1 USB connector CN1. The Virtual Com Port settings are configured as:
115200 b/s, 8 bits data, no parity, 1 stop bit, no flow control.

5.12 Arduino connectors

CN5, CN6, CN7 and CN8 are female connectors compatible with Arduino standard. Most
shields designed for Arduino UNO rev.3 can fit to the STM32F469I-DISCO discovery board.

Caution: The IOs of STM32 microcontroller are 3.3 V compatible while Arduino UNO board is 5 V

5.14 DSI LCD

The LCD module is a 4-inch 800x480 TFT color LCD with capacitive touch pane l. The LCD
is connected to the MIPI DSI interface of the microcontroller STM32F469NIH6 via the
connector CN10. The DSI (Display Serial Interface) is a specification of the MIPI Alliance
standard and defines the physical interface and the protocol used by the STM32F469NIH6
microcontroller to communicate with such LCD module.

The following ports of the microcontroller STM32F469NIH6 are dedicated to DSI interface:
DSI_D0_N, DSI_D0_P, DSI_CK_N, DSI_CK_P, DSI_D1_N, DSI_D1_P.

In addition to the DSI dedicated ports, the port PH7 of the microcontroller is used to reset
both the DSI LCD module and the capacitive touchscreen controller.

The port PJ2, connected to the LCD signal TE (Tearing Effect) is an input of the
microcontroller to synchronize the write access from the microcontroller with the LCD scan
refresh, to avoid visible artefacts on the display.

LEDK and LEDA signals of the LCD module are the cathode and anode of the backlight
LEDs.

This backlight requires a power supply voltage of typically 25 V generated from the +5 V by
a switching mode boost converter STLD40DPUR.

By controlling the EN pin of the STLD40DPUR by a low frequency PWM signal, it is possible
to switch on/off or to dim the backlight inten sity of the LCD module. The control of EN can be
done by software or by hardware:

• By default, the EN pin of the STLD40DPUR is controlled by the microcontroller
software through DSI commands and CABC signal ge nerated by th e L CD module . For
such default configuration the resistor R117 is soldered, R119 is not soldered.

• Th e STM 3 2F 4 69I -D ISC O discovery board offers the option to control the EN pin by
HW through port PA3. In such case, R117 should be removed and R119 soldered.
