Voltage Planes
All V
CC
and V
SS
pins/balls must be connected to the appropriate voltage plane. All V
CCT
and V
REF
pins/balls must be connected to the appropriate traces on the system electronics. In addition to the main
V
CC
, V
CCT
, and V
SS
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
V
SS
. 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 V
CC
voltages. They are needed to cleanly support
voltage specification variations on current and future processors. VID[4:0] are defined in Table 7. The
voltages specified in the VID table are the Battery Optimized Mode V
CC
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.
