STMicroelectronics: ST-LINK/V2 In-Circuit Debugger/Programmer for STM8 and STM32 MCU Families

Overview

The ST-LINK/V2ST-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 providing the same functionalities as the ST-LINK/V2ST-LINK/V2, the ST-LINK/V2-ISOLST-LINK/V2-ISOL features digital isolation between the PC and the target application board. It also withstands voltages of up to 2500 VRMS.

STM8 applications use the USB full speed interface to communicate with STMicroelectronic’s 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, CooCox CoIDE ( supporting ARM Cortex-M core) integrated development environments.

The ST-LINK/V2ST-LINK/V2 is designed around the STM32F103C8STM32F103C8 device which incorporates the high performance ARM, Cortex-M3 core.
