• Power Management Capabilities
• Optimized for 32-bit applications running on advanced 32-bit operating systems.
• Uses Flip-Chip Pin Grid Array (FC-PGA) Package. The FC-PGA uses the same 370-pin
zero insertion force socket (PGA370) as the PPGA. Thermal solutions are attached
directly to the back of the processor core package without the use of a thermal plate or
heat speader.
