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.

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. It is also possible to

specify a component with 1x refresh (tREFI to 7.8us) in the Extended Temperature Range.

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).
