11.2 THERMAL CHARACTERISTICS
Notes:
1. The power dissipation is obtained from the formula P
D
= P
INT
+ P
PORT
where P
INT
is the chip internal power (I
DD
xV
DD
)
and P
PORT
is the port power dissipation determined by the user.
2. The average chip-junction temperature can be obtained from the formula T
J
= T
A
+ P
D
x RthJA.
