Embedded STLINK-V3E

There are two different ways to program and debug the onboard STM32 MCU:
• Using the STLINK-V3E programming and debugging tool on the STM32U5 Nucleo-144
• Using an external debug tool connected to the CN5 STDC14/MIPI-10 connector
The STLINK-V3E makes the NUCLEO-U575ZI-Q Nucleo-144 board Arm
The embedded STLINK-V3E supports only SWD and VCP for STM32 devices. For information about debugging
and programming features of STLINK-V3, refer to the user manual STLINK-V3SET debugger/programmer for
STM8 and STM32 (UM2448) which describes in detail all the STLINK-V3 features.
STLINK-V3E description:
• 5V power supplied by CN1 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 (CN5)
• COM status LED blinking during communication with the PC (LD4)
• 5 V/300 mA output power supply capability with current limitation (U2)
• OC fault red LED alerting on USB overcurrent request (LD6)
• 5V_PWR 5 V power green LED (LD5)
Table 6 describes the CN1 USB Micro-B connector pinout.
