Introduction

The STM32F769I-EVAL evaluation board is a complete demonstration and development

platform for STMicroelectronics ARM® Cortex®-M7 core-based STM32F769NI

microcontrollers. It features the following interfaces: four I2Cs, six SPIs with three

multiplexed full-duplex I2S, SDIO, two SAIs, 8-bit to 14-bit digital camera, Ethernet MAC,

FMC, Quad-SPI. It also features four USARTs and four UART peripherals, two CAN buses,

three 12-bit ADC converters, two 12-bit DAC channels, internal 512 Kbytes of SRAM + 16

Kbytes of instruction, 2 Mbytes of Flash memory, TCM RAM + 4 Kbytes of backup SRAM,

USB OTG HS and USB OTG FS peripherals, SWD and JTAG debugging support. This

evaluation board can be used as a reference design for user application development but it

is not considered as a final application.

The full range of hardware features on the board helps the user to evaluate all the

peripherals (USB OTG HS, USB OTG FS, Ethernet, motor control, microSD™ card, USART,

audio DAC and ADC, digital microphone, CAN, SRAM, NOR Flash, SDRAM, Quad SPI

Flash, 4" DSI LCD with capacitive touch panel etc.) and develop applications. Extension

headers make provide an easy mean of connecting a daughterboard for a specific

application.The integrated ST-LINK/V2-1 provides an embedded in-circuit debugger and

programmer for the STM32.

UM2035 Hardware layout and configuration

Known limitation:

•Activating the readout protection on ST-LINK/V2-1 target, prevents the target

application from running afterwards. The target readout protection must be kept

disabled.

For all general information concerning debugging and programming features common

between ST-LINK/V2 and ST-LINK/V2-1 versions, refer to ST-LINK/V2 in-circuit

debugger/programmer for STM8 and STM32 User manual (UM1075).

Note: 1 ETM can only work at 50 MHz clock by default because the ETM signals are shared with

other peripherals. If a best performance of ETM is required (e.g. 84 MHz/98 MHz), R31,

R34, R35, R37, R39, R42, SB7, SB8, SB25, SB27 and SB28, must be removed to reduce

the stub on the ETM signals. In this way SAI, Ethernet and camera are not functional and

NOR Flash and SRAM addresses are limited to A18.

Note: 2 When JP28 is open, the NRST of the ST-LINK MCU (U21) is pulled high. When JP28 is

closed, ST-LINK MCU is reset.

6.1.1 Drivers

Before connecting the STM32F769I-EVAL evaluation 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 website.

In case the STM32F769I-EVAL evaluation board is connected to the PC before installing the

driver, the PC device manager may report some STM32F769I-EVAL interfaces as

“Unknown”. To recover from this situation, after installing the dedicated driver, the

association of “Unknown” USB devices found on the STM32F769I-EVAL evaluation board

to this dedicated driver, must be updated in the device manager manually.

Note: It is recommended to proceed using USB Composite Device, as shown in Figure 5.

Figure 5. USB composite device

6.1.2 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 a new functionality, bug fixes, support for new microcontroller families), it is

recommended to visit the www.st.com website before starting to use the STM32F769I-EVAL

board and periodically, to stay up-to-date with the latest firmware version.

Hardware layout and configuration UM2035

14/79 DocID029087 Rev 3

6.2 Power supply

The STM32F769I-EVAL evaluation board is designed to be powered by the 5 V DC power

supply and to be protected from wrong power plug-in event by PolyZen. It is possible to

configure the evaluation board to use any of the following power supply six sources:

•5 V DC power adapter connected to CN19 (JP20 jumper in position PSU). This is

default setting of power supply source selection on STM32F769I-EVAL evaluation

board.

•5 V DC power with 500mA limitation from CN22 (JP20 jumper in position STLK) (the

USB Micro-B connector of the ST-LINK/V2-1 that is showed as STLK on JP20

silkscreen and called U5V). If the USB enumeration succeeds (as explained below),

the ST-LINK U5V power is enabled, by asserting the PWR_EN pin. This pin is

connected to a power switch (ST890), which powers the board. This power switch

features also a current limitation to protect the PC in case of short-circuit. If overcurrent

(more than 600 mA) happens on the board, the LED LD11 is lit.

•5 V DC power with 500 mA limitation from CN8 (the USB OTG2 HS Micro-AB

connector (JP20 jumper in position HS).

•5 V DC power with 500 mA limitation from CN13, the USB OTG1 FS Micro-AB

connector (JP20 jumper in position FS1).

•5 V DC power with 500 mA limitation from CN14, the USB OTG2 FS Micro-AB

connector (JP20 jumper in position FS2).

•5 V DC power from CN5 and CN6 (JP20 jumper in position D5V).

The STM32F769I-EVAL evaluation board can be powered from ST-LINK USB Micro-B

connector CN22 (U5V), but only the ST-LINK circuit has the power before USB enumeration

starting, because the host PC only provides 100 mA to the boards at that time. During the

USB enumeration, the STM32F769I-EVAL board asks for the 300 mA power from the host

PC. If the host is able to provide the required power, the target STM32 is powered and the

red LED LD10 is turned on, thus the STM32F769I-EVAL board can consume maximum

300 mA current, but not more. If the host is not able to provide the requested current, the

enumeration fails. Therefore the STM32 part including the extension board will not be

powered. As a consequence the red LED LD10 remains turned off. In this case it is

mandatory to use an external power supply as an extra power supply.

E5V (from PSU) or D5V must be used as external power supply in case current

consumption of STM32F769I-EVAL board exceeds the allowed current on USB. In this

condition it is still possible to use USB for communication, for programming or debugging

only, but it is mandatory to power the board first using E5V or D5V, and 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 jumper JP20 for PSU or D5V side

2. Check that JP27 is removed

3. Connect the external power source to PSU or D5V (daughterboard mounted)

4. Check that the red LED LD10 is turned ON

5. Connect the PC to USB Micro-B connector CN22

If this order is not respected, the board may be powered by VBUS first, then by E5V or D5V,

and the following risks may be encountered:

DocID029087 Rev 3 15/79

UM2035 Hardware layout and configuration

1. If more than 300 mA current is needed by the board, the PC may be damaged or the

current can be limited by PC. As a consequence the board is not supplied correctly.

2. 300 mA will be requested at enumeration (since JP27 must be off), so there is the risk

that the request is rejected and the enumeration does not succeed if the PC cannot

provide such current. Consequently the board is not powered (LED LD10 remains off).

Note: In case the board is powered by a USB charger, there is no USB enumeration, so the led

LD10 remains set to off permanently and the board is not powered. In this specific case only

the jumper JP27 must be set to on, to allow the board to be powered anyway but in any

case the current will be limited to 600 mA by U17 (ST890).

The power supply is configured by setting the related jumpers JP2, JP15 and JP20 as

described in Table 2.

UM2035 Hardware layout and configuration

The LED LD10 is lit when the STM32F769I-EVAL evaluation board is powered by the 5 V

correctly.

To avoid the impact of USB PHY and Ethernet PHY and get precise results of current

consumption on JP2, the following cautions must be taken into account:

1. Configure Ethernet PHY into Power Down Mode by setting low level of IO_Expander

(EXP_IO1)

2. Configure USB HS PHY into Low-power mode (Register address = 04, bit 6 in USB

PHY).

6.3 Clock source

Five clock sources are available on the STM32F769I-EVAL board:

•X1, 25 MHz crystal for the HSE of the STM32F769NI

•X2, 32 KHz crystal for embedded RTC of the STM32F769NI

•X3, 24 MHz oscillator for camera module (Default on camera daughterboard)

•X4, 25 MHz crystal with socket for Ethernet PHY

•X5, 24 MHz crystal for USB OTG2 HS PHY

Note: Jumper JP12 for Ethernet clock refers to Section 6.12: Ethernet.

6.4 Reset source

The reset signal of the STM32F769I-EVAL evaluation board is active low and the reset

sources include:

•Reset button B1

•Debugging tools from JTAG/SWD connector CN16 and ETM trace connector CN12

•Daughterboard from CN5

•Embedded ST-LINK/V2-1

•RS232 connector CN7 pin 8 for ISP.

Note: The jumper JP5 must be closed when the RESET is handled by the CN7 pin 8 of the

RS-232 connector (CTS signal).

6.5 Boot option

The STM32F769I-EVAL evaluation board can boot from:

•Embedded user Flash memory

•System memory with boot loader for ISP

6.6 Audio

An audio codec WM8994ECS/R with 4 DACs and 2 ADCs inside is connected to SAI

interface of the STM32F769NI to support TDM feature on SAI port. This feature is able to

implement audio recording on digital and analog microphone and audio playback of different

audio streams on headphone and line-out at the same time.

It communicates with the STM32F769NI via I2C1 bus which is shared with LCD, camera

module, and MFX (Multi-Function expander).

The analog microphone on the headset is connected to ADC of WM8994ECS/R through the

audio jack CN28. External speakers can be connected to WM8994ECS/R via the audio jack

CN27.

Two digital microphones (MEMS microphone) MP34DT01TR are available on the

STM32F769I-EVAL evaluation board. They can be connected to either the audio codec or

the DFSDM port of the STM32F769NI by setting jumpers shown in Ta ble 7: Audio related

jumpers. The coupon connectors CN24 and CN25 can be used to support MEMS

microphone evaluation board STEVAL-MKI129V1 after removing SB78 and SB79.

An optical connector CN29 is implemented on the STM32F769I-EVAL to receive external

audio data which is compatible with SPDIF spec.
