Devices that are lead-free are marked with a
circled âe1â and have the product code:
LUxxxxxx.
a. This 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.
