Digital I/O. Serial bus bidirectional data. Open-drain output.
Digital Input. Serial bus clock.
System Ground.
Power. Can be powered by +3.3 V standby power if monitoring in low power states is required.
This pin also serves as the analog input to monitor V
CC
.
Digital Input. Core voltage ID readouts from the processor. This value is read into the VID0–VID3
Status Register. It has an on-chip 100 k
pull-up resistor (ADM1025 only).
Digital Input. Core voltage ID readouts from the processor. This value is read into the VID0–VID3
Status Register. It has an on-chip 100 k
pull-up resistor (ADM1025 only).

Digital Input. Core voltage ID readouts from the processor. This value is read into the VID0–VID3
Status Register. It has an on-chip 100 k
pull-up resistor (ADM1025 only).
Analog/Digital Input. Connected to cathode of external temperature sensing diode. If held high at
power-up, initiates NAND tree test mode.
Analog Input. Connected to anode of external temperature sensing diode.
Programmable Analog/Digital Input. Defaults to 12 V
IN
analog input at power-up, but may be pro-
grammed as VID4 Core Voltage ID readout from the processor. This value is read into the VID4
Status Register. In analog 12 V
IN
mode it has an on-chip voltage attenuator. In VID4 mode it has an
on-chip 300 k
pull-up resistor.
Analog Input. Monitors 5 V supply.
Analog Input. Monitors 3.3 V supply.
Analog Input. Monitors 2.5 V supply.
Analog Input. Monitors processor core voltage (0 V to 3.0 V).
Programmable Digital I/O. The lowest order programmable bit of the SMBus Address, sampled on
SMB activity as a three-state input. Can also be configured to give a minimum 20 ms low reset
output pulse. Alternatively, can be programmed as an interrupt output for temperature/voltage
interrupts. Functions as the output of the NAND tree in NAND tree test mode.
