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/altera-www/global/en_us/pdfs/literature/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/altera/max-v-overview/max-v-overview.html 

it is "0.5mm EQFP package". I can found the value in other documents. 

 

Does somebody tell me which is correct?

Hi k, 

0.4mm pitch is correct, based on a measurement on Altera 5M80ZE64C5N in EQFP64 package.

Thank you Martin, 

 

There are very few pitch conversion boards available for 0.4mm. 

And that is what I am afraid of.
