20-pin 1.27mm AMP Cortex Debug Cable Adapter
Ordering code
IC50113-AMP
IC50113-AMP Cortex-M Cable Adapter is used to connect the iC5000 / iC5500 / iC5700 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 AMPMODU 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 AMPMODU 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 AMP connector (for example TE connectivity, part number 1-
111196-8). A target should feature a matching part (for example TE connectivity part number 5-104549-2 in
SMT technology).
