Inner row pad size for HDQFP100

Hi,

I want to use S32K312NHT0MPAST with HDQFP100 package but I found different footprints for it over the site and I wondered which one is more accurate. My concern is about the inner pins length. In two of them the inner row has exactly the same size as the outer row but there is a footprint which the inner row is shorter (just for 100pin package). Here are the things I found:

1- https://www.nxp.com/part/S32K312NHT0MPAST in the package part the footprint which is provided by the link has the same size (inner and outer rows).

2- https://www.nxp.com/webapp/Download?colCode=S32K3_HW-DesignPackage The inner row for the 100pin package is shorter that the outer row

3- https://www.nxp.com/docs/en/package-information/SOT2045-1.pdf both of the rows have the same size

Which one is more accurate?

Thanks

Could you mark on the screenshot what exactly you have on your mind?

At least both pdfs (points 2 and 3) seems to be the same.

Pads are shown by arrow. As you can see, in the second one the inner row is shorter that the outer one.

Seems like error in the model. I will report it.

Anyway pdf drawings are relevant, I would recommend to follow that.
