Note:
1. Operating Temperature TOPER is the case surface temperature on the center/top side of the DRAM.
2. Some applications require operation of the DRAM in the Extended Temperature Range between 85C and 95C case temperature.
Full specifications are guaranteed in this range, but the following additional apply.
a) Refresh commands must be doubled in frequency, therefore, reducing the Refresh interval tREFI to 3.9us.
b) If Self-Refresh operation is required in the Extended Temperature Range, then it is mandatory to either use the Manual
Self-Refresh mode with Extended Temperature Range capability (MR2 A6=0 and MR2 A7=1) or enable the optional Auto
Self-Refresh mode (MR2 A6=1 and MR2 A7=0).
