®

Cortex® -M4 core-

based STM32F469NIH6 microcontroller. This microcontroller features thre e I

2

C interfaces,

six SPIs with two multiplexed full-duplex I

2

S interfaces, SDIO, four USARTs, four UARTs,
two CANs, three 12-bit ADCs, two 12-bit DACs, one SAI, 8 to 14-bit digital camera digital
module interface, internal 320+4 Kbytes of SRAM and 2-Mbyte Flash memory, USB HS
OTG and USB FS OTG, Ethernet MAC, FMC interface, MIPI DSI interface, Quad-SPI
interface, JTAG debugging support. This discovery board offers everything required for
users to get started quickly and develop applications easily.

The hardware features on the board helps users to evaluate the following peripherals: USB
OTG FS, microSD card, Audio DAC with headset jack, digital microphones, SDRAM, Qua d­SPI Flash memory, 4" TFT LCD using MIPI DSI interface with capacitive touch panel.The
Arduino

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.

Figure 6. USB Composite device

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

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
