Hi,
since I want to use the MSC-Interface of the TC275 in my master's thesis, I need to know the track lengths of the Pins - P02.3
- P22.0
- P22.1
- P22.2
- P22.3
- P23.4
- P23.5
- P33.13
to the Arduino Headers. I understand that you want to keep the design files confidential.
Would you be so kind to measure them for me?
Thanks

We can do this but we need to know which board revision you have. This can be found under the double row connector, at the edge of the board. It will be something like "4264.03.06210_B1". Tnx

Here are the track lengths for the latest boards:
• P02.3 =33.98
• P22.0 =27.68
• P22.1 =24.61
• P22.2 =63.56
• P22.3 =29.92
• P23.4 =64.67
• P23.5 =67.38
• P33.13 =94.56
Note that P33.13, P23.5, P23.4, P22.2 are all duplicated on other pins of the TC275. These are total net lengths in mm.

I'm impressed by your quick response. Sorry for not providing the hardware revision.
My Board is 4269.03.06210_B1
Do these lengths still apply?
By "duplicated", do you mean other IOs are connected to the same net?
Are the "total net lengths" including these duplicate pins? E.g. are the duplications adding to the total net length?
For clarification, I want to keep the total trace length equal for the MSC-lines, so I'm only interested in the given ports.

For the rev B1 board, they are as follows:
• P02.3 =33.98
• P22.0 =27.68
• P22.1 =24.61
• P22.2 =63.56 (this total length. The net goes via another AURIX pin. P22.2 is at one end, connector at the other)
• P22.3 =29.92
• P23.4 =64.67 (this total length. The net goes via another AURIX pin. P23.4 is at one end)
• P23.5 =67.38 (this total length. The net goes via another AURIX pin. P23.5 is at one end)
• P33.13 =94.56 (this total length. The net goes via 2 other AURIX pins. P33.13 is not at one end, but the middle of the daisy chain. The connector is at one end)
