■ Lead-free
a
196-p in Ball Grid Array (BGA).
Devices that are lead-free are marked with a
circle d “e1” and have the p ro duct code:
LUxxxxxx.
a. This dev ice is le ad-fr ee. Tha t is , lead h as n o t been i n tentio nally 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:

In addition, this device has be en tested and conforms to the same parametric spec ifications as previous versio ns of
the device.
