196-pin Ball Grid Array (BGA).
Devices that are lead-free are marked with a
circled “e1” and have the product code:
LUXXXXX.

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:
