Delivery recommendations
Some verifications are needed before using the Evaluation board for the first time, to make sure that no damage occurred during shipment and that no components are unplugged or lost. When the board is extracted from its plastic bag, check that no component remains in the bag. The main component to verify is the microSDTM card that may have been ejected from the connector CN13 (right side of the board). In the latest packing, the microSDTM card is provided separately in the carton box. Install this microSDTM card into CN13 before using the board.
Warning: There is an explosion risk if the battery is replaced by an incorrect one. Make sure to dispose of used batteries according to the instructions.

Refer to www.st.com for details about STLINK-V3E.
It is possible to power the Evaluation board through CN23 (embedded STLINK-V3E USB connector) even if an external tool is connected to CN8 (ETM Trace connector) or CN9 (external JTAG and SWD connector). ETM can only work at 50 MHz clock by default because ETM signals are shared with other peripherals. If better performance of ETM is required (84 MHz/98 MHz), R217, R230, R231, R234, R236, SB2, SB5, SB8, SB11, SB42, SB57 must be removed to reduce the stub on ETM signals. In this configuration, SAI and PDM are not functional and NOR flash memory and the address of SRAM are limited on A18. ETM trace function would be abnormal as SAI_SDB share the same pins with TRACE_D0, and TRACE_D0 would be forced high by SAI_SDB. When using ETM trace, it is necessary to set the ADCDAT1 pin (SAI_SDB signal of the STM32) of the audio codec (U22) by software to be tri-state.
Drivers and firmware upgrade The STLINK-V3E requires drivers to be installed on Windows®. It embeds firmware, which needs to be updated from time to time to benefit from new functionalities and bug corrections. Refer to technical note Overview of ST-LINK derivated (TN1235) for details.
Power supply
The STM32H7x7I-EVAL Evaluation board is designed to be powered by 5 V DC power supply and is protected by PolyZen from wrong power plug-in events. It is possible to configure the Evaluation board to use any of the following six sources for the power supply:
·
5 V DC power adapter connected to CN10, the power jack on the board (the Power Supply Unit on the
silkscreen of JP10 (PSU)).
·
5 V DC power with 500 mA limitation from CN23, the USB Micro-B connector of STLINK-V3E (USB 5 V
power source on the silkscreen of JP10 (STlk)). 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) that powers the board. This power switch features also a current limitation to protect the PC in
case of short-circuit on the board. If an overcurrent (more than 600 mA) happens on the board, the LED
LD11 lights up.
·
5 V DC power with 500 mA limitation from CN14, the USB OTG1_HS Micro-AB connector (USB 5 V power
source on the silkscreen of JP10 (HS)).
·
5 V DC power with 500 mA limitation from CN18, the USB OTG2_FS Micro-AB connector (USB 5 V power
source on the silkscreen of JP10 (FS2)).
UM2525 - Rev 6

Power supply
·
5 V DC power with 500 mA limitation from CN16, the USB OTG1_FS Micro-AB connector (USB 5 V power
source on the silkscreen of JP10 (FS1)).
·
5 V DC power from CN6 and CN7, the extension connectors for the daughterboard (the power source of
the daughterboard on the silkscreen of JP10 (D5V)).
The STM32H7x7I-EVAL Evaluation board can be powered from the STLINK-V3E USB connector CN23 (U5V), but only the STLINK-V3E circuit has the power before USB enumeration, because the host PC only provides 100 mA to the board at that time. During the USB enumeration phase, the STM32H7x7I-EVAL board requires 300 mA power from the host PC. If the host is able to provide the required power, the enumeration succeeds, the power transistor U19 is switched ON, the green LED LD9 is turned ON, and thus the STM32H7x7I-EVAL board is powered and can consume maximum 300 mA current. If the host PC is not able to provide the requested current, the enumeration fails. Therefore, the STM32 part including the extension board is not powered. As a consequence the green LED LD9 remains turned OFF. In this case, it is mandatory to use an external power supply to supply extra power.
E5V (from PSU) or D5V can be used as an external power supply in case the current consumption of the STM32H7x7I-EVAL board exceeds the allowed current on USB. In this condition, it is still possible to use USB for communication, 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 JP10 for PSU or D5V side
2. Check that SB35 is removed
3. Connect the external power source to PSU or D5V (daughterboard mounted)
4. Check that green LED LD9 is turned ON
5. Connect the PC to USB connector CN23
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:
1. If more than 300 mA current is needed by the board, the PC may be damaged, or current can be limited by the PC. As a consequence the board is not powered correctly.
2. 300 mA is requested at the enumeration phase (since JP15 must be OFF), so there is 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 LD9 remains OFF).
In case the STM32H7x7I-EVAL board is powered by a USB charger, there is no USB enumeration, so the LED LD9 remains set to OFF permanently and the board is not powered. Only in this specific case the jumper JP15 needs to be set to ON, to allow the board to be powered anyway.
The power supply is configured by setting the related jumpers JP9, JP10, and JP11 as described in Table 5.

Note: 6.4.1
Caution:
The LED LD9 lights up when the STM32H7x7I-EVAL Evaluation board is powered by the 5 V correctly.
To avoid the impact of USB PHY, Ethernet PHY and get precise results about current consumption on JP9, take into account the following cautions: 1. Remove JP5 to avoid Ethernet PHY influence. 2. Configure USB HS PHY into low-power mode (Register Address=04, bit 6 in USB PHY)
SMPS/LDO power supply
There are three solutions to provide power to the microcontroller VCORE logic supply: SMPS, LDO, and SMPS + LDO. Power consumption in run mode is significantly improved by generating VCORE from the internal DC/DC converter (SMPS) and the default connection must be set to SMPS. Some modifications are required to supply the microcontroller from the LDO. Below the board configuration for each case:
·
SMPS mode (default):
SB14, SB20, SB10, SB53, and L1 mounted
SB13, SB17, SB23, SB16, SB18 removed
·
LDO mode:
SB13, SB23, SB18 mounted
SB14, SB16, SB20, SB10, SB17, SB53, and L1 removed
·
SMPS + LDO mode:
SB13, SB23, SB10, SB53, and L1 mounted
SB14, SB16, SB17, SB18, and SB20 removed
A deadlock occurs if the board SMPS/LDO firmware PWR configuration does not match its hardware configuration: after the reset, the ST-LINK cannot connect the target anymore.
The firmware PWR configuration must be set as follows in the function SystemClock_Config in the file main. c:
·
If the hardware configuration is Direct SMPS (default configuration):
HAL_PWREx_ConfigSupply(PWR_DIRECT_SMPS_SUPPLY);
·
If the hardware configuration is LDO:
HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY);
If a deadlock occurs because of a mismatch between hardware and firmware PWR settings (SMPS/LDO), the user can recover the board by applying the following procedure:
1. Power off the board.
2. Set SW1 (BOOT0) to 1 (system memory). This changes the BOOT0 pin to 1 instead of 0, thus changing the device boot address to boot address 1 and making the bootloader start in System memory. This avoids starting firmware in the user flash memory with a wrong SMPS/LDO configuration versus the hardware board configuration.
3. Power on the board and connect using STM32CubeProgrammer (STM32CubeProg).
4. Erase the user flash memory.
5. Power off the board and set SW1 to 0.
6. The board is recovered and can be used normally with matching firmware PWR.

Clock source
Two clock sources (X1 and X2) are available on the STM32H7x7I-EVAL Evaluation board for the STM32H7x7XI, and embedded RTC. Other clock sources (X3 and X4) are used for their peripherals:
·
X1, 25 MHz crystal for the STM32H7x7XI, it can be disconnected by removing R15 and R16 when an
internal RC clock is used
·
X2, 32 kHz crystal for embedded RTC

Audio
An audio codec with four DACs and two ADCs inside is connected to the SAI interface of the STM32H7x7I-EVAL microcontroller to support the TDM feature on the SAI port. This feature is able to implement audio recording on digital and analog microphones and audio playback of various audio streams on headphone and lineout at the same time.
It communicates with the STM32H7x7XI through the I2C1 bus, which is shared with LCD and MFX (Multi Function eXpander).
The analog microphone on the headset is connected to the ADC of the audio codec through the audio jack CN17. External speakers can be connected to the audio codec through the audio jack CN19.
Two digital microphones are on the STM32H7x7I-EVAL Evaluation board. They can be connected to either an audio codec DFSDM or to the PDM port of the STM32H7x7XI, by setting the switch SW2 shown in the table below. For legacy, the coupon connectors CN25 and CN26 can be used to support the ST-MEMS microphone after removing the SB54 and SB55 solder bridges.

USB OTG1_HS and FS
The STM32H7x7I-EVAL Evaluation board supports USB OTG1:
·
High-speed communication through a USB Micro-AB connector (CN14), USB high-speed PHY (U13) for
high-speed function
·
Full-speed communication through another USB Micro-AB connector (CN16)
The Evaluation board can be powered by these USB connectors (CN14 or CN16) at 5 V DC with 500 mA current limitation.
As several OTG1_FS signals are shared with the OTG1_HS ULPI bus and USART1, some PCB reworks are needed when using OTG1_FS (CN16) as shown in Table 11.
Function OTG1_HS-CN14 (default)
OTG1_FS-CN16 USART1 (default)

USB OTG2_FS
The STM32H7x7I-EVAL Evaluation board supports USB OTG2 full-speed communication through a USB MicroAB connector (CN18) and USB power switch (U18) connected to VBUS. The Evaluation board can be powered by this USB connection at 5 V DC at a current up to 500 mA.
A green LED (LD10) lights up if either one of the following events occurs:
·
Power switch (U18) is ON and the STM32H7x7I-EVAL board works as a USB Host.
·
VBUS is powered by another USB HostUSB Device when the STM32H7x7I-EVAL board works as a USB
Device.
The red LED (LD8) lights up when an overcurrent occurs (IVBUS > 500 mA).
The STM32H7x7I-EVAL board must be powered by an external power supply when using the OTG function.
JP2 and SB50 must be removed when using USB OTG_FS as mentioned in Table 13. CAN-related jumpers and solder bridges.
RS-232
Communication through RS-232 is supported by the D-type, 9-pin connector CN2, which is connected to the USART1 of the STM32H7x7XI on the STM32H7x7I-EVALEvaluation board. The signals Bootloader_RESET and Bootloader_BOOT0 are added on the RS-232 connector CN2 for ISP support.
The USART1 of the STM32H7x7XI is shared with the RS-232 of the STLINK-V3E controller. Connection is switched by setting JP7 and JP8.

microSDTM card
The 8-Gbyte (or more) microSDTM card connected to the SDIO 3.0 port of the STM32H7x7XI microcontroller is available on the Evaluation board. The detection of the microSDTM card is managed by MFX GPIO15. IP4856CX25/C (M1) is an SD 3.0-compliant, 6-bit-bidirectional, dual-voltage-level translator. It is implemented on the STM32H7x7I-EVAL board and it supports SD 3.0, SDR104, SDR50, DDR50, SDR25, SDR12, and SD 2.0 in high-speed (50 MHz) and default-speed (25 MHz) modes.
External I2C connector
The I2C1 bus of the STM32H7x7XI is connected to CN4 on the STM32H7x7I-EVAL. The I2C functional daughterboard can be mounted on the CN4 connector and accessed by the microcontroller through the I2C1 bus.
CAN FD
The STM32H7x7I-EVAL Evaluation board supports one channel of the Flexible Data Rate CAN (CAN FD) communication bus, based on the 3.3 V CAN transceiver. The standby signal on the CAN FD transceiver is controlled by PD3 of the STM32H7x7XI. Other CAN FD signals are shared with USB OTG1_FS signals.

Memories
An 8M×32-bit SDRAM is connected to the SDRAM bank1 of the FMC interface of the STM32H7x7XI microcontroller.
A 1M×16-bit SRAM is connected to the NOR/PSRAM2 bank1 of the FMC interface and both 8-bit and 16-bit accesses are allowed by BLN0 and BLN1, connected to BLE and BHE of SRAM respectively.
A 128-Mbit NOR flash memory is connected to the NOR/PSRAM1 bank1 of the FMC interface. The 16-bit operation mode is selected by the pull-up resistor connected to the BYTE pin of NOR flash memory. The write protection can be enabled or disabled, depending on how the jumper JP13 is set, as showed in the table below.
Table 15. NOR flash memory related jumpers
Jumper
Description
JP13
Write protection is enabled when JP13 is ON while write protection is disabled when JP13 is OFF. Default setting: OFF
All signals for memory are also connected on memory connectors CN11 and CN12 for memory daughterboards. Limitations can happen when using other peripherals: 1. FMC addressing limitation depending on number of trace data bus used (A18 max for 4 bit ETM to A21 max
for 1 bit ETM) 2. FMC addresses limited to A18 when SAI used 3. FMC addresses limited to A22 when PDM is used In such cases, serial resistors R236 (A19), R231 (A20), R217 (A21) and R230 (A22) should be removed. Thus, memory addresses A19 to A22 are not connected to FMC and they are pulled down on the board. Memories can be addressed within a limited address range. By default, all these serial resistors are soldered on the board. If A19 is required, it is necessary to configure the (SAI_SDB) ADCDAT1 pin of the audio codec (U22) by software to be tri-state.
Twin Quad-SPI NOR flash memory
The Quad-SPI flash memory is implemented on the STM32H7x7XI microcontroller of the Evaluation board either as one twin Quad-SPI NOR flash memory (1-Gbit (2×512 Mbytes)) memory or as two Quad-SPI NOR flash memories (512 Mbytes). The two dies in the twin Quad-SPI flash memory share the same clock and chip select signals of the STM32H7x7XI microcontroller.
Analog input
The two-pin header CN5 and 10 k potentiometer RV1 is connected to PA0_C of STM32H7x7XI as an analog input. A low-pass filter can be implemented by replacing R11 and C7 with the right value of resistor and capacitor as requested by the end-user application.

STM32H747I-EVAL and STM32H757I-EVAL product information
9.1
Product marking
The stickers located on the top or bottom side of all PCBs provide product information:
·
First sticker: product order code and product identification, generally placed on the main board featuring
the target device.
Example:
Product order code Product identification
·
Second sticker: board reference with revision and serial number, available on each PCB.
Example:
MBxxxx-Variant-yzz syywwxxxxx
On the first sticker, the first line provides the product order code, and the second line the product identification. On the second sticker, the first line has the following format: "MBxxxx-Variant-yzz", where "MBxxxx" is the board reference, "Variant" (optional) identifies the mounting variant when several exist, "y" is the PCB revision, and "zz" is the assembly revision, for example B01. The second line shows the board serial number used for traceability. Parts marked as "ES" or "E" are not yet qualified and therefore not approved for use in production. ST is not responsible for any consequences resulting from such use. In no event will ST be liable for the customer using any of these engineering samples in production. ST's Quality department must be contacted prior to any decision to use these engineering samples to run a qualification activity. "ES" or "E" marking examples of location:
·
On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to the
STM32 datasheet Package information paragraph at the www.st.com website).
·
Next to the evaluation tool ordering part number that is stuck, or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.
To use the same commercial stack in their applications, the developers might need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
