Attention Valued Customer,

Subject:  Additional equivalent wafer foundries for fabrication of Virtex™ commercial (C-grade and I-grade) product family. 

Products Affected: The following commercial (C-grade and I-grade) members of Virtex product line are affected: XCV300, XCV400, XCV600, XCV800 and XCV1000. Note that this notice does not affect any Virtex-E™ devices.

Change Description: The Virtex product family is currently manufactured using 0.22µ 5 layer metal process. A new 0.22µ / 0.18µ 6 layer metal process at additional equivalent foundries will be used to manufacture the Virtex product family.
