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, 25A and 25K 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).
5. For 25K automotive speed grade, TCASE is able to extend to 105°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).
6. For -18, -25, 25I, 25A and -3 speed grades, 95°C < TCASE ≤ 105°C is not available.
