Overview

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. It facilitates communication between the PC and the target microcontroller using the Single Wire Interface Module (SWIM) for STM8 and JTAG or Serial Wire Debug (SWD) for STM32. This tool supports a wide range of application voltages and includes a direct firmware update (DFU) feature for easy upgrades.

Why Choose This Part

It offers native integration with the STMicroelectronics ecosystem and supports a broad voltage range from 1.65V to 5.5V for SWIM and up to 3.6V for JTAG/SWD. The hardware is robust, USB 2.0 full-speed compatible, and provides clear status feedback via an integrated LED.

Applications

STM32 Firmware Development
Providing JTAG and SWD debugging for Arm Cortex-M based microcontrollers with Serial Wire Viewer support.
STM8 Programming
Using the SWIM interface to program and debug 8-bit STM8 microcontrollers with support for low-speed and high-speed rates.
Production Line Flashing
Utilizing the DFU and command-line tools for automated firmware deployment in manufacturing environments.
