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, TJ, 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.

IL(max) for the I
2C interface is 0.8 V rather than the 1.5 V as specified in the I2C standard.
