Notes 3.
Permissible total power loss differs depending on the temperature (see the following figure).
How to calculate total power loss
The power consumption of the
μ
PD78044H,
μ
PD78045H, and
μ
PD78046H can be classified into the three categories
shown below. The sum of the three categories should be less than the total power loss P
T
(80 % or less of ratings is
recommended).
CPU power consumption: calculate V

Output pin power consumption: Normal output and display output are available. Power consumption when
maximum current flows into each output pin.
Pull-down resistor power consumption: Power consumption by pull-down resistor connected to display
output pin by the mask option.
