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).
