Connection with STM8

For development of applications based on STM8 microcontrollers, 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

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.

4. See Figure 11

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.
