Notes:
1. Exposure to conditions beyond those listed under Absolute Maximum Ratings may adversely affect the life and reliability of
the device
2. Operating ambient temperature is the surrounding temperature of the SDRAM.
3. Operating case temperature is the case surface temperature on the center/top side of the SDRAM
4. Supporting -4 0°C ≤ T A / T CASE ≤ 85°C with full AC and DC specifications .
5. Supporting -4 0°C ≤ T A / T CASE ≤ 85°C and being able to extend to 105°C with extend Auto Refresh commands in frequency
to a 16 mS period ( t REF = 1.95 μS).
6. During operation, the DRAM operation temperature must be maintained between -40 to 105°C for automotive parts under all
specification parameters.
