This chapter contains the DC operating conditions tables.
1) DRAM Component Case Temperature is the surface temperature in the center on the top side of any of the DRAMs.
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
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
5) Up to 3000 m.
1) Under all conditions,
2) Peak to peak AC noise on
3) Input voltage for any connector pin under test of 0 V ≤
