Infineon AUTO 26-pin (1.27mm) Adapter
The Infineon DAP AUTO 26-pin (1.27mm) Adapter is used to connect to iC7mini or iC7pro on one side, while connecting to the embedded target on the other side. This adapter is equipped with a 26-pin (1.27mm) DAP AUTO connector, guaranteeing compatibility with a diverse range of 32-bit TriCore™ AURIX™– TC2xx, TC3xx and TC4x microcontroller families. This adapter implements External Watchdog Disable pin.
•Hardware: iC7mini BlueBox / iC7pro BlueBox
•Microcontroller Architecture: 32-bit TriCore™ AURIX™– TC2xx, TC3xx and TC4x
The following pinout is valid on the target side:

26-pin Infineon AUTO pinout
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. |
If the 26-pin 1.27mm pitch ribbon cable gets damaged, it can be ordered as a spare part under the ordering codes:
•IA26PIN26PIN127
•IA26PIN26PIN127-CUST - Custom cable length must be specified at the order.
Note that the optional length should be reasonable (e.g. 10 cm) since the quality of electrical signals degrades with prolonging the cable. |
BlueBox functionality with this cable, intended for rare situations when the standard debug adapter cannot connect to the target due to physical obstacles, is not guaranteed. Using the BlueBox at lower debug frequency scan speeds without trace functionality may be an acceptable compromise. You should test the BlueBox with a custom-length ribbon cable to ensure compatibility with winIDEA. |
Refer to Hardware Setup and Configuration Tutorial to get more information on how to connect the hardware. |
