Uhm, do you mean the minimum width of the tracks used to make the EVAL's board? Or maybe the structure width of the STM32L4R9AII6 used on the STM32L4R9I-EVAL?

If the latter, then this is a 90nm technology.

Where can I find this information?

Unless I went too quickly I didn't see it in the RM or the datasheet.

The better source I find is Wikipedia! https://en.wikipedia.org/wiki/STM32
