4-pin ERNI ST STM8
|
This debug adapter is used to connect the iC5000 and the iC5700 BlueBox to ST STM8 based target featuring 4-pin ERNI target debug connector with the STM8 pinout.
The debug adapter connects to the 25cm 40-pin ribbon cable coming from the BlueBox and to the target debug connector on the other side. Refer to the BlueBox User Manual for more details on connecting the debug adapter.
The following pinout is valid on the target side:

4-pin ERNI ST STM8 target pinout
Signal Direction is described from the BlueBox perspective.

When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
4-pin ERNI ST STM8 Debug Adapter features resettable fuses on all pins. These fuses protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades away.
The debug adapter connects to the target via the ERNI MiniBridge 4-pin connector female (P/N 839033). A target should feature a matching part, for example ERNI MiniBridge 4-pin connector right angle male (P/N 214012) or ERNI MiniBridge 4-pin connector vertical male (P/N 284697).
