20-pin 1.27mm Cortex Debug Cable Adapter
Ordering code
IC50113
Note: This product is obsolete and is fully replaced with IC50118
IC50113 Cortex-M Adapter Board is used to connect the iC5000 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
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).
