Description
There are three different ways to program and debug the onboard STM32 MCU.
•Using the embedded STLINK-V3EC programming and debugging tool on the STM32H573I-DK Discovery
kit
•Using an external debug tool connected to the CN12 MIPI10 connector (SWD/JTAG)
•Using an external debug tool connected to the CN18 MIPI20 connector (SWD/JTAG/TRACE)
The STLINK-V3EC facility for debugging and flashing is integrated into the STM32H573I-DK.
Supported features in STLINK-V3EC:
•
5 V / 3.2 A power supply capability through the CN10 USB Type-C® connector

Using an external debug tool to program and debug the on-board STM32
Before connecting any external debug tool to the MIPI10 or MIPI20 debug connector, the SWD and VCP signals
from STLINK-V3EC must be isolated. For this, set the jumper JP1. This disables the U26 level shifter and then
isolates
Once JP1 is set, an external debug tool can be connected to CN12 MIPI10 debug connector or to CN18 MIPI20
debug/trace connector.

Using an external debug tool to program and debug the on-board STM32
When using the external debug connectors (CN12 or CN18), the STLINK-V3EC can be used to supply the
STM32H573I-DK board through CN10 USB Type-C® connector. Otherwise, another power supply source can be
used as described on Section 9 Power supply.
Two level shifters are used on VCP and SWD interfaces to offer a debug capability when operating the target
MCU at 1.8 V. The level shifters are used to allow compatibility between target MCU signals (1V8 or 3V3) and
STLINK-V3EC signals (3V3).
The U26 level shifter is disabled with the JP1 jumper to isolate the output I/Os from STLINK-V3EC when an
external debug tool is used. The configuration of the JP1 jumper is explained in Table 15. JP1 jumper settings.

9 Power supply
For powering the STM32H573I-DK kit, there are several options. With this, the user gets the flexibility to choose
the power supply which suits the application most.
The JP4 jumper allows the user to select any of the following power sources:
•STLK: 5 V from STLINK-V3EC USB Type-C® connector (CN10)
•USB-PD: 5 V from user USB Type-C® connector (CN17)
•5VIN: 5 V to 12 V from ARDUINO® connector (pin 1 of CN14)
•CHGR: 5 V from STLINK-V3EC (CN10) without enumeration.
The green power LED (LD5) indicates the presence of 5 V supply voltage.

Power supply
9.1
Supplying the board by the STLINK-V3EC USB Type-C® connector (default
setting)
To power the STM32H573I-DK in this way, the USB Host (a PC) needs to be connected to the STLINK-V3EC
USB Type-C® connector of the STM32H573I-DK via a USB cable. In this case, JP4 must be fitted on pin [1-2] to
select the STLK power source. This is the default setting.
Figure 8. JP4 set on the STLK pin
If the USB enumeration succeeds, the STLK power is enabled, by asserting the T_PWR_EN signal (from
STLINK-V3EC). This pin is connected to an over voltage protection (U34) with management of the max current
delivery.
•If the host can provide the required power, the U34 power switch is enabled, the green power LED (LD5) is
turned ON, and the
•If the host is not able to provide the requested current, the enumeration fails. The U34 power switch
remains OFF and the MCU part including the extension board is not powered. As a consequence, the
green power LED (LD5) remains OFF. In this case, it is recommended to use another external power
supply.
STM32H573I-DK board and its shield can consume up to 3 A max.

The STM32H573I-DK can be supplied also through the pin 1 of the CN14 ARDUINO® Uno V3 connector (marked
‘VIN’ on the board).
In this case, the 5 V power source selector (JP4) must be fitted between pin 5 and pin 6 to select the VIN power
source.

14.5 Audio
The audio codec used on the STM32H573I-DK is a low-power stereo codec with a headphone amplifier, which is
connected to the STM32H573IIK3Q SAI2 interface. It communicates with the STM32H573IIK3Q microcontroller
via an I2C-bus shared with the touch panel of the LCD and the USB-C® protection. The I2C-bus address of the
audio codec is 0x94.
Several audio connections are available on the STM32H573I-DK board:
•Analog audio output lines of the audio codec are used to drive a headphone connected to the audio jack
connector (CN9) since the analog input of the codec is used as microphone input when a microphone is
connected to the audio jack connector (CN9)
•For microphone-based applications, a MEMS microphone daughterboard can be plugged into the audio
connector CN2. The daughterboard interfaces with the STM32H573IIK3Q via the SAI1 peripheral using a
PDM interface.
14.5.1 Digital MEMS microphone
The STM32H573I-DK Discovery kit also provides one digital MEMS microphone (U20) which is connected to the
MCU's SAI1 interface. The I/O interface is described in Table 12.
STM32H573IIK3Q.

U20
The selection between the on-board digital MEMS microphone and the external digital MEMS microphone
daughterboard plugged into the audio connector (CN2) is made by the U23 SPDT switch. The DETECn signal
(PE0) controls the switch. Table 13 shows the selection between the on-board digital MEMS microphone and the
external digital MEMS microphone daughterboard.
Note:The audio codec and digital MEMS microphones operate at 1.8 V and 3.3 V.

Figure 12. MB1400 Wi‑Fi® module
Note:
UM3143 - Rev 1
The MB1400 Wi‑Fi® module is addressable over UART or SPI interface. By default, the MB1400 uses the SPI
interface (SPI5) to communicate with the STM32H573IIK3Q MCU.
The MB1400 Wi‑Fi® module does not require any operating system. It contains a complete and integrated TCP/IP
protocol stack that only requires AT commands to establish
STM32H573I-DK with Wi‑Fi® communication.
1.As the MB1400 Wi‑Fi® module firmware might evolve during the lifetime of the Wi‑Fi® module product,
users must make sure the
MB1400 Wi‑Fi® module.
Refer to the X-WIFI-EMW3080B product webpage to find the update procedure and the latest version of
MB1400 Wi‑Fi® module firmware.
the
2.The MB1400 Wi‑Fi® module works only at 3.3 V with the help of the onboard 3.3‑V regulator IC.
Consequently, when using the MB1400, the user must ensure that JP2 is fitted on [1-2] on the
STM32H573I-DK.

ARDUINO® Uno V3 connectors (CN13, CN14, CN15, CN16)
The ARDUINO® Uno V3 connectors CN13, CN14, CN15, and CN16 are female connectors. They are compatible
with the ARDUINO® Uno V3 standard. Most shields designed for ARDUINO® Uno V3 fit to the STM32H573I-DK
board.
The STM32 microcontroller I/Os are 3.3 V compatible instead of 5 V for ARDUINO® Uno.
Table 31 shows the references of the ARDUINO® Uno V3 connectors.
Before using any ARDUINO® Uno V3 shield, it is important to refer to Section 9.1 Supplying the board by the
STLINK-V3EC USB Type-C® connector (default setting) for a correct configuration of JP4.
The 3V3 on the pin 4 of the CN14 ARDUINO® Uno V3 connector is not a power input for the STM32H573I-DK board. This simplifies the power architecture.
2. The external voltage applied to pin VIN on pin 1 of CN14 must be less than 11.5 V at 25°C ambient temperature. If a higher voltage is applied on the regulator U8, it may overheat and
could be damaged.
3.
By default, the pin 1 and the pin 2 of the CN16 ARDUINO® Uno V3 connector are connected to ADC MCU input ports PF12 and PA6 respectively, by configuring the solder bridges:
SB23 and SB24 ON, SB21 and SB25 OFF. In case it is necessary to connect the I2C interface signals on pin 1 and pin 2 of CN16, instead of ADC inputs, SB23 and SB24 need to be
OFF, and SB21 and SB25 need to be ON.

17 STM32H573I-DK product information
17.1 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
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.
“U” marking option at the end of the standard part number
