13.2 THERMAL CHARACTERISTICS
Notes:
1. The power dissipation is obtained from the formula PD=PINT+PPORT where PINT is the chip internal power (IDDxVDD)
and PPORT is the port power dissipation determined by the user.
2. The average chip-junction temperature can be obtained from the formula TJ = TA + PD x RthJA.
