ST-LINK/V2 in-circuit debugger/programmer
for STM8 and STM32
Introduction
The ST-LINK/V2 is an in-circuit debugger/programmer for the STM8 and STM32
microcontrollers. The single wire interface module (SWIM) and the JTAG/serial wire
debugging (SWD) interfaces facilitate communication with any STM8 or STM32
microcontroller operating on an application board.
In addition to providing the same functionalities of 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 V
RMS
.
The USB full-speed interface enables communication with a PC and:
• STM8 devices via ST Visual Develop (STVD) or ST Visual Program (STVP) software
(available from STMicroelectronics)
• STM32 devices via IAR
™
, Keil
®
, STM32CubeIDE, STM32CubeProgrammer, and
STM32CubeMonitor integrated development environments.
