Package different between KF40 and NF40

Hi,

Thank you for reaching out to Intel Community.

KF40 and NF40 are the Package Plan for Intel® Arria® 10 devices and both have the same 40 mm × 40 mm, 1517-pin FBGA.

However, they are different in terms of General-Purpose I/O (GPIO) Count, High-Voltage I/O Count, LVDS Pairs and Transceiver Count for each Product Line under Intel® Arria® 10 devices.

You can refer to the comparison between these two packages in the Product Catalog at link below (refer page 23-25):

Hope this helps.
