Infineon AUTO 20-pin (1.27mm) Adapter
|
The Infineon DAP AUTO 20-pin (1.27mm) Adapter is used to connect to iC7mini BlueBox on one side, while connecting to the embedded target on the other side. This adapter is equipped with a 20-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.
Requirements
•Hardware: iC7mini BlueBox
•Microcontroller Architecture: 32-bit TriCore™ AURIX™– TC2xx, TC3xx and TC4x

20-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. |
Additional cable
If the 20-pin 1.27mm pitch ribbon cable gets damaged, it can be ordered as a spare part under ordering codes:
•IA20PIN20PIN127
•IA20PIN20PIN127-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. |
