Description ST-LINK/V2
2/4 DocID018751 Rev 4
Description
The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32
microcontroller families. 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®, IAR™,
Keil® or TASKING integrated development environments.
