Perhaps the attached will be of use. I built a board using this symbol
and package and it works.

Especially if the spec sheet comes from Freescale -- their tech writers

I haven't looked in the library, but this part should be
there. Instead of looking for a TQFP, look for a QFP or a
PQFP. This is an old footprint and should be very common.
If all else fails, you can download a footprint dimension library
from PCB Libraries at http://www.pcblibraries.com/. T

The specs on page 27 are enough to mak
Hello,
