Part VII Thermal Calculation and Measurement  
For the following discussions, PD = (VDD × IDD) + PI/O, where PI/O is the power  
dissipation of the I/O drivers.  
7.1 Estimation with Junction-to-Ambient Thermal  
Resistance  
An estimation of the chip junction temperature, TJ, in °C can be obtained from the equation:  
TJ = TA + (RθJA × PD)  
where:  
TA = ambient temperature (ºC)  
RθJA = package junction-to-ambient thermal resistance (ºC/W)  
PD = power dissipation in package  
The junction-to-ambient thermal resistance is an industry standard value which provides a  
quick and easy estimation of thermal performance. However, the answer is only an  
estimate; test cases have demonstrated that errors of a factor of two (in the quantity TJ TA)  
are possible.  
7.2 Estimation with Junction-to-Case Thermal  
Resistance  
Historically, the thermal resistance has frequently been expressed as the sum of a  
junction-to-case thermal resistance and a case-to-ambient thermal resistance:  
RθJA = RθJC + RθCA
