10-pin 1.27mm Infineon DAP Debug Adapter features resettable fuses on pins 1, 2, 3, 4, 5, 6, 8,
9 and 10. These fuses protect debug signals against overcurrent and cycle back to a conductive
state after the excessive current fades away.
The debug adapter connects to the target through one of the two 10-pin 1.27mm connectors.
Note that only one is to be connected to the target!
The one at the end of the cable is with a so called “strain relief” option (Samtec FFSD-05-01-N-
SR) and is the robust type when it comes to connecting and disconnecting it from the target
very often. This is the recommended connection connector to be used. However, the
connector is a bit wider and therefore the target must have a matching part populated.
Matching part on the target side is e.g. Samtec ESHF-105-01-L-D (full frame connector) or
Samtec FTSH-105-01-F-DV-K (connector without the frame at the side).
The second connector is 1cm away from the first one toward the blue box and is a “standard”
type (Samtec FFSD-05-01-N). It’s much less robust and is prone to fail if the cable is not handled
cautiously or just connected/disconnected too many times. This connector should be used
when the target doesn’t provide the matching target connector for the “strain relief” type
connector. Matching part on the target is Samtec SHF-105-01-L-D or Samtec FTSH-105-01-F-
DV-K (connector without the frame at the side).
Recommendation for the target side connector is the FTSH-105-01-F-DV-K connector, which
matches the connector with and without the strain relief option.
