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.
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.
Ground.
Shared analog Ground.
Reserved Ground. This pin is reserved by Intel and may have factory test functions.
For normal operation, connect to ground.
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.
No Connect. This pin is not connected internally.
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
3.3 V I/O Power Supply.
1.8V Analog Power Supply.
1.8V analog power supply for the clock recovery.
Input power for the XTAL regulator.
1.2V Power supply. This is for analog and digital circuits.
1.2V Analog Power Supply.
Input power for the ICS regulator.
