Figure 60. System Level Thermal Model for MPC8544E (Not to Scale)
The Flotherm library files of the parts have a dense grid to accurately capture the laminar boundary layer
for flow over the part in standard JEDEC environments, as well as the heat spreading in the board under
the package. In a real system, however, the part will require a heat sink to be mounted on it. In this case,
the predominant heat flow path will be from the die to the heat sink. Grid density lower than currently in
the package library file will suffice for these simulations. The user will need to determine the optimal grid
for their specific case.

Thermal Management Information
This section provides thermal management information for the flip chip plastic ball grid array (FC-PBGA)
package for air-cooled applications. Proper thermal control design is primarily dependent on the
system-level design—the heat sink, airflow, and thermal interface material. The MPC8544E implements
several features designed to assist with thermal management, including the temperature diode. The
temperature diode allows an external device to monitor the die temperature in order to detect excessive
temperature conditions and alert the system; see Section 20.3.4, “Temperature Diode,for more
information.
