22-pin Samtec ERF8 DAP2 Cable Adapter
Ordering code
IC50164
This adapter is used to connect the iC5000 / iC5500 / iC5700 development system to Infineon Aurix based target
providing Aurora trace interface. It connects to the Debug/Trace module on one side and to the target debug
connector on the other side. It can be used only in conjunction with targets featuring 22-pin Samtec ERF8 target
debug connector, which typically provides Aurora trace interface along the DAP debug interface.
With jumper J1 in position 1-2 (default), normal debug operation is configured. The debugger drives MCU reset
line low during the initial debug connection and then takes control over the microcontroller.
With jumper J1 in position 2-3, Hot Attach operation is configured. In this case, all debug signals from the
iC5000 / iC5500 / iC5700 unit are disconnected and the target starts running as soon as the power is applied to
the target. When Hot Attach command is issued from winIDEA, the debugger connects to the MCU and control
over the MCU is taken without resetting the MCU. Depending on the target MCU, refer to the TriCore technical
notes document for more details on Hot Attach configuration and use.
The following pinout is valid on the target side:

Samtec 22-pin AGBT target pinout
Note: 22-pin Samtec Cable Adapter features resettable fuses on pins 2, 4, 5, 6, 10, 11, 12, 17 and 22. 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 22-pin connector (Samtec part number ASP-137971-02). The target must
have populated a matching part (for example Samtec part number ASP-137969-01, Samtec Series ERF8, Rugged
High Speed Socket).
