Operating Conditions
TABLE 8
Absolute Maximum Ratings
Attention: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to
the device. This is a stress rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this specification is not implied. Exposure
to absolute maximum rating conditions for extended periods may affect reliability.

1)2)3)
1) Within the DRAM Component Case Temperature range all DRAM specification will be supported.
2) 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.
3) Above 85 °C DRAM case temperature the Auto-Refresh command interval has to be reduced to tREFI = 3.9 μs.
