DocumentDocumentUM1075 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 the communication with any STM8 or STM32 microcontroller located on an application board. In addition to providing 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. 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®, IARTM, Keil®, and TASKING integrated development environments.

ST-LINK/V2-ISOL product contents C E D A B Hardware configuration 4 Hardware configuration UM1075 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 4, the ST-LINK/V2 provides two connectors: · an STM32 connector for the JTAG/SWD and SWV interface · an STM8 connector for the SWIM interface The ST-LINK/V2-ISOL provides one connector for the STM8 SWIM, STM32 JTAG/SWD and SWV interfaces.

C = STM8 SWIM, STM32 JTAG and SWD target connector 4. D = Communication activity LED 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 · SWIM cable with two 4-pin, 2.54 mm connector or SWIM separate-wires cable UM1075 Hardware configuration 4.1.1 Standard ERNI connection with SWIM flat ribbon Figure 5 shows how to connect the ST-LINK/V2 if a standard ERNI 4-pin SWIM connector is present on the application board. Figure 5. ERNI connection A B A B C C 1. A = Target application board with ERNI connector 2. B = Wire cable with ERNI connector at one end 3. C = STM8 SWIM target connector 4. See Figure 11: SWIM ST-LINK/V2 standard ERNI cable. Figure 6 shows that pin 16 is missing on the ST-LINK/V2-ISOL target connector. This missing pin is used as a safety key on the cable connector, to guarantee connection of the SWIM cable in the correct position on the target connector even pins, used for both SWIM and JTAG cables.

Table 2. SWIM flat ribbon connections for ST-LINK/V2 Pin no. Name Function Target connection 1 VDD Target VCC(1) MCU VCC 2 DATA SWIM MCU SWIM pin 3 GND GROUND GND 4 RESET RESET MCU RESET pin 1. The power supply from the application board is connected to the ST-LINK/V2 debugging and programming board to ensure signal compatibility between both boards. Figure 8. Target SWIM connector Table 3 summarizes the signal names, functions, and target connection signals using the separate-wires cable. As the SWIM separate-wires cable has independent connectors for all pins on one side, it is possible to connect the ST-LINK/V2-ISOL to an application board without a standard SWIM connector. On this flat ribbon, all signals are referenced by a specific color and a label to ease the connection on target. Table 3.

Hardware configuration UM1075 TVCC, SWIM, GND and SWIM-RST can be connected to a low-cost 2.54 mm pitch connector or to pin headers available on the target board. 4.2 Connection with STM32 applications For STM32 developments, the ST-LINK/V2 needs to be connected to the application using the standard 20-pin JTAG flat ribbon provided. Table 4 summarizes the signals names, functions, and target connection signals of the standard 20-pin JTAG flat ribbon. Table 4. JTAG/SWD cable connections Pin no.

JTAG debugging flat ribbon layout 9LHZHGIURPDERYH3&% AI Note: For low cost applications or when the standard 20-pins-2.54mm-pitch-connector footprint is too big, it is possible to implement the Tag-Connect solution to save cost and space on the application board. The Tag-Connect adapter and cable provide a simple reliable means of connecting ST-LINK/V2 or ST-LINK/V2-ISOL to the PCB without requiring a mating Hardware configuration UM1075 component on application PCB. For more details on this solution and application-PCB-footprint information, visit www.tag-connect.com. The references of components compatible with JTAG and SWD interfaces are: a) TC2050-ARM2010 adapter (20-pin- to 10-pin-interface board) b) TC2050-IDC or TC2050-IDC-NL (No Legs) (10-pin cable) c) TC2050-CLIP retaining clip for use with TC2050-IDC-NL (optional) 4.3 ST-LINK/V2 status LEDs The LED labeled `COM' on top of the ST-LINK/V2 shows the ST-LINK/V2 status (whatever the connection type). When the: · LED is blinking RED: the first USB enumeration with the PC is taking place. · LED is RED: communication between the PC and ST-LINK/V2 is established (end of enumeration). · LED is blinking GREEN/RED: data are being exchanged between the target and the PC. · LED is GREEN: the last communication has been successful. · LED is ORANGE: ST-LINK/V2 communication with the target has failed.
