Symbol
Type
Name and Function
VSS
P
Ground.
AVSS
P
Shared analog Ground.
RSVD_VSS
P
Reserved Ground.
This pin is reserved by Intel and may have factory test functions.
For normal operation, connect to ground.
RSVD_NC
P
Reserved No connect.
This pin is reserved by Intel and may have factory test
functions. For normal operation, do not connect any circuit to these pins. Do not
connect pull-up or pull-down resistors.
NC
P
No Connect.
This pin is not connected internally.
RSVD_VCC
P
Reserved VCC.
This pin is reserved by Intel and may have factory test functions.
For
normal operation, connect to VCC through a 1K pull-up resistor
Type
Name and Function
CTRL12
A
1.2V Control.
LDO voltage regulator output to drive external PNP pass transistor. If
1.2V is already present in the system, leave output unconnected. To achieve optimal D3
power consumption, leave the output unconnected and use a high-efficiency external
switching regulator.
CTRL18
A
1.8V Control.
LDO voltage regulator output to drive external PNP pass transistor. If
1.8V is already present in the system, leave output unconnected. To achieve optimal D3
power consumption, leave the output unconnected and use a high-efficiency external
switching regulator.
