Voltage Planes
All VCC and VSS pins/balls must be connected to the appropriate voltage plane. All VCCT and VREF
pins/balls must be connected to the appropriate traces on the system electronics. In addition to the main
VCC, VCCT, and VSS power supply signals, PLL1 and PLL2 provide analog decoupling to the PLL
section. PLL1 and PLL2 should be connected according to Figure 2. Do not connect PLL2 directly to
VSS. Appendix A contains the RLC filter specification.

Voltage Identification
There are five voltage identification balls/pins on the Mobile Intel Pentium III Processor-M. These
signals can be used to support automatic selection of VCC voltages. They are needed to cleanly support
voltage specification variations on current and future processors. VID[4:0] signals are defined in Table
7. The voltages specified in the VID table are the Battery Optimized mode VCC voltages. The
VID[4:0] signals are open drain on the processor and need pullup resistors to 3.3V on the motherboard.
Please refer to the mobile VR guidelines provided by Intel for additional information.
