Notes:

1. MAX storage case temperature TSTG is measured in the center of the package, as shown

in Figure 12. This case temperature limit is allowed to be exceeded briefly during pack-

age reflow, as noted in Micron technical note TN-00-15, “Recommended Soldering Pa-

rameters.”

2. MAX operating case temperature TC is measured in the center of the package, as shown

in Figure 12.

3. Device functionality is not guaranteed if the device exceeds maximum TC during opera-

tion.

4. Both temperature specifications must be satisfied.

5. Operating ambient temperature surrounding the package.
