Comment
Use to reset the STLINK-V3E MCU
when an external debug probe is used.
Normal mode: use the STLINK-V3E
debug probe
STLINK-V3E able to reset target MCU
STLINK-V3E not able to reset Target
MCU configuration to use when an
external debug probe is used.
VDD voltage selection is 3V3
VDD voltage selection is 1V8
No internal VDD power supply
(External 3V3 or 1V8 needed)
MCU is powered by the on‑board
power supplies.
Use an ammeter to measure the MCU
power consumption, or connect an
external source 3V3 or 1V8 on pin
2 to supply the MCU (STLINK-PWR
tools with STM32CubeMonitor-Power or
ULPBench probe as exemple)
5V source from STLINK-V3E
®
5V source from ARDUINO VIN 7-12V
5V source from 5V_EXT
®
5V source from USB Type-C
5V source from USB_CHGR
(from CN1 STLINK-V3E USB connector
without overcurrent protection)
NO 5V power source, configuration
when external 3V3 is used.
