Introduction
The STM32F469I-DISCO discovery board (32F469IDISCOVERY) is a complete
®
®
demonstration and development platform for STMicroelectronics ARM
Cortex
-M4 core-
2
based STM32F469NIH6 microcontroller. This microcontroller features three I
C interfaces,
2
six SPIs with two multiplexed full-duplex I
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, Quad-
SPI Flash memory, 4" TFT LCD using MIPI DSI interface with capacitive touch panel.The
™
Arduino
compatible connectors expand the functionality with a wide choice of specialized
shields.The extension header makes it possible to easily connect a daughterboard for
specific application. The integrated ST-LINK/V2-1 provides an embedded in-circuit
debugger and programmer for the STM32 MCU.

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 found on STM32F469I-DISCO as “Unknown”. -
Page 12: Power Supply
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. STM324F69I- DISCO board requests for 500mA power to the host PC. -

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. -
Page 14: Clock Source
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 ST- LINK/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. -
