Lead-free¹196-pin Ball Grid Array (BGA).

Devices that are lead-free are marked with a

circled “e1” and have the product code:

LUxxxxxx.

¹This device is lead-free. That is, lead has not been intentionally added, but lead may still exist as an

impurity at <1000 ppm. The Material Declaration Data Sheet, which includes lead impurity levels and the

concentration of other Restriction on Hazardous Substances (RoHS)-banned materials, is available at:

ftp://download.intel.com/design/packtech/material_content_IC_Package.pdf#pagemode=bookmarks

In addition, this device has been tested and conforms to the same parametric specifications as previous

versions of the device.

For more information regarding lead-free products from Intel Corporation, contact your Intel Field Sales

representative.
