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 provide 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) or ST Visual Program (STVP) software. STM32 applications use the USB full-speed interface to communicate with Atollic(R), IARTM, Keil(R) or TASKING integrated development environments. 2/4 DocID018751 Rev 4 ST-LINK/V2 Revision history Revision history Table 1.
