21.2
Thermal Management Information
For the following sections, PD = (VDD IDD) + PI/O, where PI/O is the power dissipation of the I/O drivers.
21.2.1
Estimation of Junction Temperature with Junction-to-Ambient
Thermal Resistance
An estimation of the chip junction temperature, TJ, can be obtained from the equation:
TJ = TA + (RJA PD)
where:
TJ = junction temperature (C)
TA = ambient temperature for the package (C)
RJA = junction-to-ambient thermal resistance (C/W)
PD = power dissipation in the package (W)
The junction-to-ambient thermal resistance is an industry standard value that provides a quick and easy
estimation of thermal performance. As a general statement, the value obtained on a single layer board is
appropriate for a tightly packed printed-circuit board. The value obtained on the board with the internal
planes is usually appropriate if the board has low power dissipation and the components are well separated.
Test cases have demonstrated that errors of a factor of two (in the quantity TJ – TA) are possible.
21.2.2
Estimation of Junction Temperature with Junction-to-Board
Thermal Resistance
The thermal performance of a device cannot be adequately predicted from the junction-to-ambient thermal
resistance. The thermal performance of any component is strongly dependent on the power dissipation of
surrounding components. In addition, the ambient temperature varies widely within the application. For
many natural convection and especially closed box applications, the board temperature at the perimeter

Note:
1. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board)
temperature, ambient temperature, airflow, power dissipation of other components on the board, and board thermal resistance.
2. Per JEDEC JESD51-2 with the single layer board horizontal. Board meets JESD51-9 specification.
3. Per JEDEC JESD51-6 with the board horizontal.
4. Thermal resistance between the die and the printed-circuit board per JEDEC JESD51-8. Board temperature is measured on
the top surface of the board near the package.
5. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method
1012.1).
6. Thermal characterization parameter indicating the temperature difference between package top and the junction temperature
per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written as Psi-JT.
