EQFP pin spacing 0.4mm or 0.5mm?

I am a very newbie to Altera devices.

Now, I'm checking the package dimension of 5M40ZE64C5N
which is EQFP 64pin device.

There are two different descriptions about pin spacing
and I'm confusing.

The altera package document
https://www.altera.com/content/dam/a...e/ds/pkgds.pdf
says the pin spacing is 0.4mm in p57

But in a different document like http://dkc1.digikey.com/JP/ja/TOD/Al...-Overview.html
it is "0.5mm EQFP package". I can found the value in other documents.

Does somebody tell me which is correct?
