7.3 Embedded STLINK-V3EC
STLINK-V3EC is the embedded version of STLINK-V3 included in the design of the Discovery board. It allows
access to the programming, debugging, and monitoring functions of the STM32 through the USB STLK connector
(CN6).
The STLINK-V3EC facility for debugging and programming is integrated into the STM32N6570-DK Discovery kit.
The embedded STLINK-V3E supports JTAG/SWD and VCP for STM32 devices.
Features supported in STLINK-V3EC:
• 5 V power supplied by the USB Type-C
®
connector (CN6)
• USB 2.0 high-speed-compatible interface
• JTAG and Serial Wire Debug (SWD) interface
• MIPI20 compatible connector (CN10)
• COM status LED (LD4), which blinks during communication with the PC
• Power status LED (LD3), which identifies the status of current output to the board
Table 4 describes the USB Type-C
®
connector (CN6) pinout.

7.3.1 STLINK-V3E drivers
The installation of drivers is not mandatory since Windows 10
®
but allocates an ST‑specific name to the ST-LINK
COM port in the system device manager.
For detailed information on the ST-LINK USB drivers, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
7.3.2 STLINK-V3EC firmware upgrade
STLINK-V3EC embeds a firmware upgrade (stsw-link007) mechanism through the USB-C
®
port. The firmware
might evolve during the lifetime of the
STLINK-V3EC product (for example to add new functionalities, fix bugs,
and support new microcontroller families). Therefore, it is recommended to keep the STLINK-V3EC firmware up
to date before using the STM32N6570-DK Discovery board. The latest version of this firmware is available from
the www.st.com website.
