CC
Digital Input (Open Drain). SMBus serial clock input. Requires SMBus pull-up.
Ground Pin for the ADT7463.
Power Supply. Can be powered by 3.3 V standby if monitoring in low power states is required. V
CC
is also
monitored through this pin. The ADT7463 can also be powered from a 5 V supply. Setting Bit 7 of
Configuration Register 1 (Reg. 0x40) rescales the V
CC
input attenuators to correctly measure a 5 V supply.
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register (Reg. 0x43).
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read in to the VID register (Reg. 0x43).
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan3. Can be reconfigured as an analog in-
put (AIN3) to measure the speed of 2-wire fans.
Digital Output (Open Drain). Requires 10 k
typical pull-up. Pulsewidth modulated output to control FAN 2 speed.
Digital Output (Open Drain). This pin may be reconfigured as an
SMBALERT
interrupt output to signal
out-of-limit conditions.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 1. Can be reconfigured as an analog in-
put (AIN1) to measure the speed of 2-wire fans.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 2. Can be reconfigured as an analog in-
put (AIN2) to measure the speed of 2-wire fans.
Digital I/O (Open Drain). Pulsewidth modulated output to control Fan 3/4 speed. Requires 10 k
typical pull-up.

ADDRESS
ENABLE
If pulled low on power-up, this places the ADT7463 into Address Select mode, and the state of Pin 14 will
determine the ADT7463’s slave address.
Digital Input (Open Drain). Fan tachometer input to measure speed of Fan 4. Can be reconfigured as an analog in-
put (AIN4) to measure the speed of 2-wire fans.

THERM
If in Address Select mode, this pin determines the SMBus device address.
Alternatively, the pin may be reconfigured as a bidirectional
THERM
pin. Can be used to time and monitor
assertions on the
THERM
input. For example, can be connected to the
PROCHOT
output of Intel’s Pentium 4
processor or to the output of a trip point temperature sensor. Can be used as an output to signal overtemperature
conditions.

Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register
(Reg. 0x43).
Analog Input. Monitors +5 V power supply.

input. For example, can be connected to the
PROCHOT
output of Intel’s Pentium 4 processor or
to the output of a trip point temperature sensor. Can be used as an output to signal overtemperature conditions.
Analog Input. Monitors +12 V power supply.
Digital Input (Open Drain). Voltage supply readouts from CPU. This value is read into the VID register
(Reg. 0x43). Supports VRM10 solutions.
Analog Input. Monitors +2.5 V supply, typically a chipset voltage.
Digital Output (Open Drain). This pin may be reconfigured as an
SMBALERT
interrupt output to signal
out-of-limit conditions.
Analog Input. Monitors processor core voltage (0 V–3 V).
Digital Output (Open Drain). Pulsewidth modulated output to control Fan 1 speed. Requires 10 k
typical pull-up.
Also functions as the output from the XOR tree in XOR Test Mode.
