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
information.
The recommended attachment method to the heat sink is illustrated in
attached to the printed-circuit board with the spring force centered over the die. This spring force should
not exceed 10 pounds force (45 Newton).
The system board designer can choose between several types of heat sinks to place on the device. There
are several commercially-available heat sinks from the following vendors:
