iSystem iC5000 Hardware Reference

 iSYSTEM, October 2016 21/69
 20-pin 2.54mm ARM Cable Adapter
Ordering code
IC50111-1
This adapter is used to connect the iC5000 / iC5500 / iC6000 development system to Cortex-M, Cortex-A,
Cortex-R or to the older ARM7and ARM9 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 2.54 pitch target debug
connector with ARM pinout.
When using this adapter to connect the development system to the target based on Cortex-M architecture,
double check that the pinout matches with the one from the target.
The following pinout is valid on the target side:

20-pin ARM pinout
Note: 20-pin 2.54mm ARM Cable Adapter features resettable fuses on all pins except for pin 11 and 19. These
fuses protect debug signals against overcurrent and cycle back to a conductive state after the excessive current
fades away.
The adapter connects to the target via a 20-pin 2.54 mm connector (for example Yamaichi: FAS-2001-2101-2-
0BF). A target should feature a matching part (for example WÜRTH ELEKTRONIK: 612 020 216 21).
