8.5 Power Current Consumption
Unless otherwise specified:
Item
Current consumption
in SLEEP mode
Current consumption
in HALT mode
Current consumption
during execution
Current consumption
during execution in heavy
load protection mode
LCD circuit current
LCD circuit current
in heavy load protection mode
LCD circuit current when the
power voltage booster is active
LCD circuit current in heavy load
protection mode when the
power voltage booster is active
SVD circuit current
Note) 1
This value is added to the current consumption during execution when the LCD circuit is active. Current consumption
increases according to the display contents and panel load.
2
This value is added to the current consumption during execution in heavy load protection mode when the LCD circuit is
active. Current consumption increases according to the display contents and panel load.
3
This value is added to the current consumption during execution when the power voltage booster and the LCD circuit are
active. Current consumption increases according to the display contents and panel load.
4
This value is added to the current consumption during execution in heavy load protection mode when the power voltage
booster and the LCD circuit are active. Current consumption increases according to the display contents and panel load.
5
This value is added to the current consumption during execution or current consumption during execution in heavy load
protection mode when the SVD circuit is active.
