Thermal Characteristics
This section provides information about operating temperature range, power dissipation, and package thermal resistance. Power
dissipation on I/O pins is usually small compared to the power dissipation in on-chip logic and it is user-determined rather than
being controlled by the MCU design. In order to take PI/O into account in power calculations, determine the difference between
actual pin voltage and VSS or VDD and multiply by the pin current for each I/O pin. Except in cases of unusually high pin current
(heavy loads), the difference between pin voltage and VSS or VDD will be very small.
The average chip-junction temperature (TJ) in °C can be obtained from:
TJ = TA + (PD × θJA)
Eqn. 1
where:
TA = Ambient temperature, °C
θ
JA = Package thermal resistance, junction-to-ambient, °C/W
PD = Pint + PI/O
Pint = IDD × VDD, Watts — chip internal power
PI/O = Power dissipation on input and output pins — user determined
For most applications, PI/O << Pint and can be neglected. An approximate relationship between PD and TJ (if PI/O is neglected)
is:
PD = K ÷ (TJ + 273°C)

1 Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting
site (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and
board thermal resistance.
