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.
