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