iSystem iC5000 Hardware Reference

 iSYSTEM, October 2016 31/69
 20-pin 1.27mm Cortex Debug Cable Adapter
Ordering code
IC50118
This adapter is used to connect the iC5000 / iC5500 / iC6000 development system to Cortex-M based target. It
connects to Debug/Trace module on one side and to the target debug connector on the other side. It can be used
for targets featuring 20-pin 1.27mm pitch target debug connector with Cortex-M pinout.
The following pinout is valid on the target side:

20-pin Cortex-M pinout
Blue colored signals are required for trace.
Note: 20-pin 1.27mm Cortex-M Cable Adapter features resettable fuses on pins 1, 2, 4, 6, 8 and 10. These
protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades
away. Signals on pins 12, 14, 16, 18 and 20 are protected via 100 ohm serial resistors.
The adapter connects to the target via a 20-pin 1.27mm connector (for example SAMTEC: FFSD-10-01-N). A
target should feature a matching part (for example SAMTEC: FTSH-110-01-F-DV-K).
