MPC8240 Integrated Processor Hardware Specifications
System Design Information
voltage, the MPC8240 always performs 3.3-V signaling as described in the PCI Local Bus Specification,
(Rev 2.1). The MPC8240 only tolerates 5-V signals when interfaced into a 5-V PCI bus system.

Thermal Management Information
This section provides thermal management information for the tape ball grid array (TBGA) 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. To reduce the die-junction temperature, heat
sinks may be attached to the package by several methods: adhesive, spring clip to holes in the printed-circuit
board, or package and mounting clip and screw assembly. See Figure 26.
Figure 26. Package Exploded Cross-Sectional View with Several Heat Sink Options
Figure 27 depicts the die junction-to-ambient thermal resistance for four typical cases:
A heat sink is not attached to the TBGA package, and there exists high board-level thermal loading
of adjacent components.
A heat sink is not attached to the TBGA package, and there exists low board-level thermal loading
of adjacent components.
A heat sink (for example, ChipCoolers #HTS255-P) is attached to the TBGA package, and there
exists high board-level thermal loading of adjacent components.
A heat sink (for example, ChipCoolers #HTS255-P) is attached to the TBGA package, and there
exists low board-level thermal loading of adjacent components.
