iSystem iC5000 - 20-pin 1.27 mm Cortex Debug Adapter Connector Comparison; Connector Robustness Comparison

 iSYSTEM, October 2016 20/69
 20-pin 2.54mm Cortex Debug Cable Adapter (obsolete)
Ordering code
IC50111-2
Note: This adapter is obsolete but might still be required with certain old targets, featuring 20-pin 2.54 mm target
debug connector with the Cortex-M pinout.
This adapter is used to connect the iC5000 / iC5500 / iC6000 development system to Cortex-M (M0, M0+, M1,
M3, and M4) 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 Cortex-M
pinout.
The following pinout is valid on the target side:

20-pin Cortex-M pinout
Note: 20-pin 2.54mm Cortex-M Cable Adapter features resettable fuses on pins 1, 2, 4, 6, 8 and 10. These
protect debug signals against overcurrent. These fuses 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).
