7.16.4 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 CAN
‑
FD features:
• The CAN FD TX/RX cannot be operated simultaneously with the UCPD interface.
• The CAN FD RX cannot be operated simultaneously with the EXT-MEMS MDF1.
7.17 Smartcard
7.17.1 Description
The STM32U575I-EV Evaluation board supports one smartcard interface. The CN31 smartcard connector is used
as a card reader. The smartcard interface is on the bottom side of the board.
7.17.2 Operating voltage
The smartcard interface is only compatible with the 2.7 to 3.6 V MCU voltage range. Low power MCU 1.8 V is not
supported by the smartcard interface.
