Thermal Calculation and Measurement
For the following discussions, PD= (VDDL × IDDL) + PI/O, where PI/O is the power dissipation of the I/O
drivers.
NOTE
The VDDSYN power dissipation is negligible.
7.1
Estimation with Junction-to-Ambient Thermal Resistance
An estimation of the chip junction temperature, T
J, in °C can be obtained from the following equation:
TJ = TA + (RθJA × PD)
where:
TA = ambient temperature (C)
RθJA = package junction-to-ambient thermal resistance (C/W)
PD = power dissipation in package
The junction-to-ambient thermal resistance is an industry standard value that 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.
