The ST-LINK is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. The SWIM and JTAG/SWD interface is used to communicate with the STM8 or STM32 microcontroller located on your own application board.

On the PC side, the USB full speed interface is used to communicate with:

1 ST Visual Develop (STVD) or ST Visual Program (STVP) software from

STMicroelectronic's for the STM8,

2 ATOLLIC, IAR and KEIL Integrated Development Environments for the STM32.


Key Features

1 The 5V power supplied by USB connector

2 USB 2.0 full speed interface compatible

3 USB standard A to Mini-B cable provided

4 SWIM specific features:

 (1) 1.65 V to 5.5 V application voltage supported on SWIM interface

 (2) SWIM low speed and high speed modes supported

 (3) SWIM programming speed rate:

9.7 Kbytes/s in low speed

12.8 Kbytes/s in high speed

 (4) SWIM cable for connection to an application with pin headers or 2.54 mm pitch connector

5 JTAG/SWD specific features:

  3 V to 3.6 V application voltage supported on JTAG/SWD interface and 5 V tolerant inputs

  JTAG/SWD cable provided for connection to a standard JTAG 20-pin pitch 2.54 mm connector

6 Direct firmware update feature supported

7 Status LED which blinks during communication with PC

8 Operating temperature 0 to 50 °C


Release History

Since May-2011, ST-LINK New Revision has been released. Hence, we're happy to provide our customers new products with better looking & better reliability.



Application Example

Connecting the PC and STM8/STM32 application board through a ST-LINK to establish hardware connection

Connection with STM8 applications

The ST-LINK should be connected to the STM8 application via the SWIM separate-wires cable, which is delivered with the product.

As the SWIM separate-wires cable has independent connectors for all pins on one side, it is possible to connect the ST-LINK 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.




Connection with STM32 applications

For STM32 developments the ST-LINK must be connected to the application using the standard 20-pin female-female JTAG flat ribbon provided.




Package Contains


USB type A to Mini-B cable × 1

20-pin JTAG/SWD flat ribbon × 1

4-pin SWIM separate-wires cable × 1
