ST STM32U575I-EV User manual

Introduction
The STM32U575I-EV Evaluation board is designed as a complete demonstration and development platform for the
STMicroelectronics Arm® Cortex®-M33 core‑based microcontroller with Arm® TrustZone® and the Armv8-M mainline security
extension.
The STM32U575I-EV Evaluation board is based on an ultra-low-power STM32U575AII6Q microcontroller with 2 Mbytes of
Flash memory and 786 Kbytes of SRAM, one external memory interface supporting an LCD interface, two Octo‑SPI memory
interfaces, one USB Type-C® 2.0 FS device and host with Power Delivery controller interface (UCPD) compliant with USB Type-
C® r1.2 and USB PD specification r3.0, one camera interface, one SDMMC interface, one 14-bit and one 12-bit ADCs, two
12-bit DACs, two operational amplifiers, two ultra‑low‑power comparators, four digital filters for sigma‑delta modulation, up to 16
timers, touchkey capability, and SWD, JTAG, and ETM interface debugging support.
The full range of hardware features on the STM32U575I-EV Evaluation board helps the user to develop applications and
evaluate all the peripherals, such as USB Type-C® connector with USB PD, motor control connector, CAN FD transceiver, USB
2.0 FS, RS-232, audio DAC, microphone ADC, dot-matrix TFT LCD, IrDA, IR LED, IR receiver, LDR, SRAM, camera interface,
Octo‑SPI Flash memory, microSD™ card, sigma-delta modulators, smartcard slot, I2C, and EEPROM.
The daughterboard and extension connectors provide an easy way to connect a daughterboard or wrapping board for the user's
specific application.
Furthermore, the onboard STLINK-V3E debugger provides out‑of‑the‑box loading and debugging capabilities, as well as a USB
Virtual COM port bridge.

7.2 Default board configuration
By default, the STM32U575I-EV Evaluation board is configured with VDD_MCU at 3.3 V. It is possible to set the
board with VDD_MCU at 1.8 V. Before switching to 1.8 V, check that the extension module and external shield
connected to the STM32U575I-EV Evaluation board are 1.8 V compatible.
