Power dissipation(1)
1.
The maximum power dissipation is obtained from the formula PD = (TJ -TA) / RthJA. The power dissipation
of an application can be defined by the user with the formula: PD =PINT +PPORT where PINT is the chip
internal power (IDD xVDD) and PPORT is the port power dissipation depending on the ports used in the
application.
