Ordering code
IC50190
This adapter is used to connect the iC5000 / iC5500 / iC5700 development system to ST STM8 based target. It
connects to the Debug/Trace module on one side and to the target debug connector on the other side. It can be
used for targets featuring 4-pin ERNI target debug connector with the STM8 pinout.
The following pinout is valid on the target side:

4-pin ERNI ST STM8 target pinout
Note: 4-pin ERNI ST STM8 Cable 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 adapter ends with the ERNI MiniBridge 4-pin connector female (P/N 839033). On the target side, ERNI
MiniBridge 4-pin connector right angle male (P/N 214012) or ERNI MiniBridge 4-pin connector vertical male
(P/N 284697) can be used.
