The single-wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board. In addition to providing the same functionalities as the ST-LINK/V2, the ST-LINK/V2-ISOL features digital isolation between the PC and the target application board. It also withstands voltages of up to 1000 Vrms. STM8 applications use the USB full-speed interface to communicate with the ST Visual Develop (STVD-STM8) or ST Visual Programmer (STVP-STM8) software, or with integrated development environments from third-parties. STM32 applications use the USB full-speed interface to communicate with the STM32CubeIDE software tool or with integrated development environments from third-parties.

All customer data is only stored in the RAM of the STM32F103C8T6 microcontroller resident in the ST-LINK/V2. This location is transient and volatile. All the contents in this location is deleted when the ST-LINK/V2 power is turned off. The STM32F103C8T6 also uses Flash memory, which is non-volatile. The Flash memory includes an STMicroelectronics proprietary firmware, which must not be modified by the user. This Flash memory does not store any user data under the normal mode of operation of the ST-LINK/V2 product. Table 2.
