2.4.8.2 Self-Refresh Temperature Range - SRT

SRT applies to devices supporting Extended Temperature Range only. If ASR = 0b, the Self-Refresh Temperature (SRT)

Range bit must be programmed to guarantee proper self-refresh operation. If SRT = 0b, then the DRAM will set an

appropriate refresh rate for Self-Refresh operation in the Normal Temperature Range. If SRT = 1b then the DRAM will set

an appropriate, potentially different, refresh rate to allow Self-Refresh operation in either the Normal or Extended

Temperature Ranges. The value of the SRT bit can effect self-refresh power consumption, please refer to the IDD table

for details.

For parts that do not support the Extended Temperature Range, MR2 bit A7 must be set to 0b and the DRAM should not

be operated outside the Normal Temperature Range.
