Compared to ST-LINK/V2 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 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. 6.1.1 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 the www.st.com webpage. 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”. To recover from this situation, after installing the dedicated driver downloaded from the www.st.com webpage, 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 the below Figure 6. Note: Prefer using the “USB Composite Device” handle for a full recovery. Figure 6. USB Composite device 6.1.2 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 during the life span of STM32F469I-DISCO to DocID028183 Rev 2 11/40 39 Hardware layout and configuration UM1932 include new functionality, fix bugs or support new target microcontroller families. It is therefore recommended to keep ST-LINK/V2-1 firmware up to date. The latest version is available at 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 STM32F469I-DISCO. The whole process is controlled from a Windows PC application also available at www.st.com. 6.2 Power supply 6.2.1 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 6.2.2: 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 its 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. The red LED LD5 is lighted on to confirm the presence of +5 V voltage. In case VIN, +5V is used to power the board, this power source must comply with the standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability. 6.2.2 Supplying the board through ST-LINK/V2-1 USB port 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 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. 12/40 DocID028183 Rev 2 UM1932 Hardware layout and configuration 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. 6.2.3 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. 6.2.4 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 Jumper, solder bridge Description JP5 IDD is used to measure STM32 current consumption manually by multimeter. Default setting: Closed by a jumper JP5 SB8 JP2 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 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) DocID028183 Rev 2 13/40 39 Hardware layout and configuration UM1932 Table 1. Power related jumpers (continued) Jumper, solder bridge Description 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: JP2 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): 6.3 Clock source 6.3.1 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 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. C26 is not necessary and remains not populated. 6.3.2 LSE clock source The 32.768 KHz crystal X3 is the clock source for the embedded RTC. 6.4 Reset source The reset signal of STM32F469I-DISCO board is low active and the reset sources include: 14/40 Reset button B1, providing solder bridge SB1 is closed (default setting) Embedded ST-LINK/V2-1, providing solder bridge SB2 is closed (default setting) Arduino compatible connector CN6 pin 3 Extension connector CN12 pin 4 DocID028183 Rev 2 UM1932 6.5 Hardware layout and configuration Audio outputs An audio DAC CS43L22 U5 from Cirrus Logic outputs the audio to a stereo headphone 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 headphone 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. 6.6 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 bridges 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 . 6.7 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 6.2: Power supply for more details on each supply source. 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. DocID028183 Rev 2 15/40 39 Hardware layout and configuration 6.8 UM1932 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. 6.9 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. 6.10 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. 6.11 Virtual COM port The serial interface USART3 is directly available as a virtual COM port 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. 6.12 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 I/Os of STM32 microcontroller are 3.3 V compatible while Arduino UNO board is 5 V compatible.

Before using pin4 of CN6 as +3.3V input, the solder bridge SB8 must be removed. Otherwise the board STM32F469I-DISCO could be damaged by the overcurrent. 2. The external voltage applied to pin VIN should be in the range 6 to 9V at 25°C ambient temperature. If a higher voltage is applied the regulator U10 may overheat and could be damaged. 3. By default pin 5 and pin 6 of connector CN8 are PC5 and PA4 respectively. They are enabled by the default configuration of solder bridges: SB10 and SB12 closed, SB9 and SB11 opened. If necessary to have an I2C interface on pins 5 and 6 of connector CN8, change the configuration solder bridges: open SB10 and SB12, close SB9 and SB11. Table 3.

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 intensity 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 generated by the LCD module. For such default configuration the resistor R117 is soldered, R119 is not soldered. The STM32F469I-DISCO 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. Table 5.
