Introduction


SITUATION:
  • ST-LINK - OBSOLETE
  • ST-LINK-v2 - ACTIVE
  • ST-LINK-v2/ISOL - ACTIVE

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.
The single wire interface module (SWIM) and JTAG and Serial Wire Debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.

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, TASKING, etc, integrated development environments.

ST-LINK v2 replaces the ST-LINK.
It supports all the features of ST-LINK plus some additional features at the same price. ( The price is arround : 25€)

    • SWIM low-speed and high-speed modes supported
    • SWIM programming speed rate: 9.7 Kbytes/s in low speed and 12.8 Kbytes/s in high speed
    • SWIM cable for connection to the application via an ERNI standard vertical (ref: 284697 or 214017) or horizontal (ref: 214012) connector
    • SWIM cable for connection to the application via a pin header or a 2.54 mm pitch connector
  • JTAG specific features
    • 1.65 V to 3.6 V application voltage supported on the JTAG interface and 5 V tolerant inputs
    • JTAG cable for connection to a standard JTAG 20-pin pitch 2.54 mm connector
