Description
Decoupling: This signal is for RTC decoupling only. This
signal requires decoupling.
Decoupling: Internally generated 1.5V powered off of
Suspend Well. This signal requires decoupling. Decoupling is
required even if this feature is not used.
Decoupling: 1.05 V Suspend well supply that is supplied
internally by Internal VRs. This signal requires decoupling.
Decoupling: This signal may require decoupling. Leave no
connect if coupling is not required.
Reference for 5 V tolerance on core well inputs. This power
may be shut off in S3, S4, S5 or G3 states.
Reference for 5 V tolerance on suspend well inputs. This
power is not expected to be shut off unless the system is
unplugged
1.05 V supply for core well logic. This power may be shut off
in S3, S4, S5 or G3 states.
3.3 V supply for core well I/O buffers. This power may be shut
off in S3, S4, S5 or G3 states.
1.05 V supply for the Intel Management Engine. This plane
must be on in S0 and other times the Intel Management Engine
is used.
3.3V supply for the Intel Management Engine I/O and SPI I/O.
This is a separate power plane that may or may not be powered
in S3–S5 states. This plane must be on in S0 and other times
the Intel Management Engine is used.
