4-pin ERNI ST STM8 Debug Adapter
Ordering code
IC50190
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
When connecting the BlueBox to the new embedded target for the first time, double
check that the debug adapter pinout matches with the target debug connector. Note
that a mismatch can result in a 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).
