26-pin 2.54 mm ColdFire Cable Adapter
Ordering code
IC50130
This adapter is used to connect the iC5000 development system to Freescale ColdFire based target. It connects
between the Debug/Trace module and the target debug connector. It can be used for targets featuring 26-pin
2.54mm pitch target debug connector with ColdFire pinout.
The following pinout is valid on the target side:

ColdFire 26-pin target pinout
Blue colored signals are required for trace.
Note: 26-pin 2.54 mm ColdFire Cable Adapter features resettable fuses on pins 2, 4, 7, 8, 9, 10, 24 and 26. These
protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades
away. Signals on pins 1, 12-19 and 24 are protected via 47 ohm serial resistors.
The adapter connects to the target via a 26-pin 2.54 mm connector (for example Yamaichi: FAS-26-17). A target
should feature a matching part (for example WÜRTH ELEKTRONIK: 612 026 216 21).
