UM1075 User manual 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 microcontroller families. The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces, facilitate communication with any STM8 or STM32 microcontroller located on an application board. The USB full-speed interface allows communication with a PC and: ● STM8 devices via ST Visual Develop (STVD) or ST Visual Program (STVP) software (which are available from STMicroelectronics) STM32 devices via Atollic, IAR, Keil, and TASKING integrated development environments. ● Table 1.

UM1075 Hardware configuration 3 Hardware configuration The ST-LINK/V2 is designed around the STM32F103C8 device which incorporates the high- performance ARM®, Cortex™-M3 core. It is available in a TQFP48 package. As shown in Figure 3, the ST-LINK/V2 provides two connectors: an STM32 connector for the JTAG/SWD and SWV interface ● an STM8 connector for the SWIM interface ● Figure 3.

Hardware configuration UM1075 3.1 Connection with STM8 applications For STM8 developments, the ST-LINK/V2 can be connected to the target board by two different cables, depending on the connector available on the application board. These cables are: ● SWIM flat ribbon with a standard ERNI connector at one end and a 4-pin connector at the other end SWIM cable with two 4-pin, 2.54 mm connectors ● 3.1.1 Standard ERNI connection with SWIM flat ribbon Figure 4 shows how to connect the ST-LINK/V2 if a standard ERNI 4-pin SWIM connector is present on the application board.
