Notes:
1. All speed grades support 0°C ≤ T CASE ≤ 85°C with full JEDEC AC and DC specifications.
2. For -18, -25, 25L and -3 speed grades, -40°C ≤ T CASE < 0°C is not available.
3. 25I, 25A, 25K and -3A speed grades support -40°C ≤ T CASE ≤ 85°C with full JEDEC AC and DC specifications.
4. For all speed grade parts, T CASE is able to extend to 95°C with doubling Auto Refresh commands in frequency to a 32 mS
period ( t REFI = 3.9 μS) and to enter to Self Refresh mode at this high temperature range via A7 "1" on EMR (2).
5. For 25K automotive speed grade, T CASE is able to extend to 105°C with doubling Auto Refresh commands in frequency to a
32 mS period ( t REFI = 3.9 μS) and to enter to Self Refresh mode at this high temperature range via A7 "1" on EMR (2).
6. For -18, -25, 25L, 25I, 25A, -3 and -3A speed grades, 95°C < T CASE ≤ 105°C is not available.
