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.

7.3 Embedded STLINK-V3E
7.3.1 Description
There are two different ways to program and debug the onboard STM32 MCU:
1. Using the embedded STLINK-V3E programming and debugging tool which is on the STM32U575I-EV
Evaluation board
2. Using an external debug tool connected to the CN18 STDC14/MIPI-10 connector
The STLINK-V3E makes the STM32U575I-EV Evaluation board Arm® Mbed Enabled™.
The embedded STLINK-V3E only supports SWD and VCP for STM32 devices:
• 5 V power supplied by the CN26 USB connector
• USB 2.0 high-speed-compatible interface
• JTAG and SWD protocols compatible with 1.7 to 3.6 V application voltage and 5 V tolerant input I/Os
• Serial Wire Viewer (SWV) output
• STDC14/MIPI-10 compatible connector (CN18)
• Status COM LED which blinks during communication with the PC (LD4)
• Fault red OC LED alerting on USB overcurrent request (LD3)
• 5 V / 500 mA output power supply capability with current limitation (U20)
• 5 V power green LED (LD2)

7.3.2 Drivers
Before connecting the STM32U575I-EV Evaluation board to a Windows PC via USB, the user must install a driver
for the STLINK-V3E (not required for Windows 10). It is available on the www.st.com website.
In case the STM32U575I-EV Evaluation board is connected to the PC before the driver is installed, some
STM32U575I-EV Evaluation board interfaces may be declared as Unknown in the PC device manager. In this
case, the user must install or update the driver files, and update the driver of the connected device from the
device manager as shown in Figure 8.
Note: Prefer using the USB Composite Device handle for a full recovery.

Note: 37xx:
• 374E for STLINK-V3E without bridges functions
• 374F for STLINK-V3E with bridges functions
7.3.3 STLINK-V3E firmware upgrade
The STLINK-V3E embeds a firmware upgrade mechanism for in-situ upgrades through the USB port. As the
firmware may evolve during the lifetime of the STLINK-V3E product (For example new functionalities, bug fixes,
support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use
the STM32U575I-EV Evaluation board and periodically, to stay up-to-date with the latest firmware version.
7.3.4 Using an external debugging tool to program and debug the on-board STM32
There are 2 basics ways to support an external Debug tool:
1. Keep the embedded STLINK-V3E running. Power on the STLINK-V3E at first until the red LED COM lights.
Then connect the external debugging tool through the CN18 STDC14/MIPI-10 debug connector.
2. Set the embedded STLINK-V3E in the high‑impedance state: When setting the STLK_NRST JP32 jumper
JP32 is ON, the embedded STLINK-V3E is in the reset state and all GPIOs are set in high impedance. Then
the user can connect his external debugging tool through the CN18 STDC14/MIPI-10 debug connector.

using the STDC14 features:
• By default, only a MIPI-10 connector is present on the CN18 footprint.
• The STDC14 function is mainly limited to the SWD function, the TDI and TDO functions are optional.
