1) DRAM Component Case Temperature is the surface temperature in the center on the top side of any of the DRAMs. For
measurement conditions, please refer to the JEDEC document JESD51-2
2) Within the DRAM Component Case Temperature Range all DRAM specifications will be supported
3) Above 85
°
C DRAM Case Temperature the Auto-Refresh command interval has to be reduced to
t
REFI
= 3.9
μ
s
4) Self-Refresh period is hard-coded in the DRAMs and therefore it is imperative that the system ensures the DRAM is below
85
°
C Case Temperature before initiating Self-Refresh operation.
5) Up to 3000 m.
