7.12.7 I/O restriction to other features
Caution: Due to the sharing of some I/Os of STM32U575AII6Q by multiple peripherals, the following limitations apply in
using the AUDIO features:
The audio codec (SAI1_FS_B) cannot be operated simultaneously with motor control.
The MEMS on ADF1 cannot be operated simultaneously with the CN29 ADF1 EXT MEMS daughterboard.
The MEMS on ADF1 cannot be operated simultaneously with the full JTAG.
The MEMS on ADF1 cannot be operated simultaneously with the STMod+ SPI_MISO2 interface.
The MEMS on ADF1 cannot be operated simultaneously with the comparator1 input.

7.13.1 Description
The STM32U575I-EV Evaluation board supports USB full-speed (FS) communication. The CN1 USB connector is
a USB Type-C
®
connector.
The STM32U575I-EV Evaluation board supports USB Type-C
®
sink and source modes.
An LD1 green LED lights up when V
BUS
is powered by a USB host when the STM32U575I-EV Evaluation board
works as a USB device, or when STM32U575AII6Q provides the 5 V USB to external devices.
7.13.2 Operating voltage
The STM32U575I-EV Evaluation board supports 5 V USB voltage, from 4.75 to 5.25 V.
MCU VDD_USB only supports the 3.3 V voltage.
7.13.3 USB FS device
When a USB host connection to the CN1 USB Type-C
®
connector of STM32U575I-EV Evaluation board is
detected, the STM32U575I-EV Evaluation board starts behaving as a USB device. Depending on the powering
capability of the USB host, the board can take power from the V
BUS
terminal of CN1. In the board schematic
diagrams, the corresponding power voltage line is called 5V_UCPD.
Section 7.8 provides information on how to use the powering option.
Table 24 describes the hardware configuration for the USB interface.
