4.29 Power and Ground Signals –Table 2
Name
Description
VccDMI
Power supply for DMI.
1.1 V or 1.05 V based on the processor used. Please refer to the
respective processor documentation to find the appropriate
voltage level.
VccLAN
1.05 V supply for LAN controller logic. This is a separate
power plane that may or may not be powered in S3–S5 states.
NOTE:
VccLAN may be grounded if Intel LAN is disabled.
VccRTC
3.3 V (can drop to 2.0 V min. in G3 state) supply for the RTC
well. This power is not expected to be shut off unless the RTC
battery is removed or completely drained.
NOTE:
Implementations should not attempt to clear CMOS by
using a jumper to pull VccRTC low. Clearing CMOS in an
Ibex Peak-based platform can be done by using a jumper on
RTCRST# or GPI.
VccIO
1.05 V supply for core well I/O buffers. This power may be
shut off in S3, S4, S5 or G3 states.
VccSus3_3
3.3 V supply for suspend well I/O buffers. This power is not
expected to be shut off unless the system is unplugged.
VccSusHDA
Suspend supply for Intel® High Definition Audio. This pin
can be either 1.5 or 3.3 V.
VccVRM
1.5V / 1.8 V supply for internal PLL and VRMs
VccpNAND
1.8 V supply for Dual Channel NAND interface. This power is
supplied by core well. If unused, this pin can be left as no
connect.
