Thermal Calculation and Measurement
For the following discussions, PD= (VDD x 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 x 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 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.
Output Low Voltage
IOL = 2.0 mA (CLKOUT)
IOL = 3.2 mA 3
IOL = 5.3 mA 4
IOL = 7.0 mA (TXD1/PA14, TXD2/PA12)
IOL = 8.9 mA (TS, TA, TEA, BI, BB, HRESET, SRESET)
