• Manufacturer Part Number: W83627DHG-PT
• Manufacturer: Nuvoton Technology Corporation of America

Specifications of W83627DHG-PT

• Pin Count: 128
• Lead Free Status / RoHS Status: Compliant

The W83627DHG-P provides a PECISB pin that can be connected to a PECI host (e.g. chipset), so
the W83627DHG-P becomes a bridge between that PECI host and the PECI client (e.g. CPU with
PECI function). The bridge can pass the CPU PECI signals by programming Configure Register at
Logical Device C, CR [E5h] Bit 0. An illustration is provided below (ICH8 is the alternative PECI host).
