13.2 THERMAL CHARACTERISTICS
Notes:
1. The maximum chip-junction temperature is based on technology characteristics.
2. 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 (IDDxVDD) and PPORT is the port power dissipation depending on the ports used in the applica-
tion.
