Answer 2: For typical backup current consumption and temperature characteristics, see the graphs in 10. 1
Answer 3: AC timing is designed to secure margins including variations and therefore difficult to change in
Answer 4: As in Answer 3 above, the operating temperature range is difficult to change in principle, provid-
Answer 1: Backup current consumption is defined as current consumption in battery backup with the CE
Question 1 : What is the difference between backup current consumption and standby current con-
sumption?
Question 2 : How is it possible to know typical backup current consumption and temperature character-
istics in determining the battery capacity?
Question 3 : What is the cause of partial mismatching of AC timing with the high-speed CPU?
Question 4 : Is it possible to extend the operating temperature range of –20˚C to +70˚C?
