20-pin 1.27mm AMP CoreSight Debug Adapter
|
This adapter is used to connect the iC5000 and the iC5700 development system to the Cortex based target. It’s used to connect to the embedded target featuring a 20-pin 1.27mm AMPMODU target debug connector with the ARM CoreSight 20 pinout. Its operating voltage range is 3.3V - 5.0V.
The debug adapter connects to the 25 cm 40-pin ribbon cable coming from the BlueBox and to the target debug connector on the other side.
The following pinout is valid on the target side:

ARM CoreSight 20 pinout
Blue colored signals are parallel trace signals.
Signal Direction is described from the BlueBox perspective.
|
When initially connecting the BlueBox to a target, ensure the debug adapter pinout matches the Target connector to avoid potential hardware failure. |
The debug 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 debug 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.

Make sure this adapter fits on your target connector - check Cross Table. |
