Notes 3.
Permissible total power loss differs depending on the temperature (see the following figure).
How to calculate total power loss
The following three power consumption are available for the
m
PD78042F. The sum of the three power consumption
should be less than the total power loss P
T
(80 % or less of ratings is recommended).
CPU power consumption: calculate V

DD1
(MAX.).
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.
