System Management Bus Clock.
This is the negative Analog input (current
sink) from the remote thermal diode. This
serves as the negative input into the A/D.
Digital Input.
from the remote thermal diode. This serves
as the positive input into the A/D.
This is the negative Analog input (current
sink) from the remote thermal diode. This
serves as the negative input into the A/D.
Digital Input.
from the remote thermal diode. This serves
as the positive input into the A/D.
Analog input for +Vccp (processor voltage:
0 to 3.0V).
Input for monitoring a fan tachometer input.
Input for monitoring a fan tachometer input.
Input for monitoring a fan tachometer input.
/Interrupt output to indicate a thermal
and/or voltage event.
Input for monitoring a fan tachometer input.
If in Address Select Mode, determines the
SMBus address of the device.
PWM Output 1 controlling speed of fan.
When in XOR tree test mode, functions as
XOR Tree output.
PWM Output 2 controlling speed of fan.
/Interrupt output to indicate a thermal
and/or voltage event.
PWM Output 3 controlling speed of fan.
If pulled to ground at power on, enables
Address Select Mode (Address Select pin
controls SMBus address of the device).
Positive Power Supply. Nominal 3.3V.
VCC is monitored by the Hardware
Monitoring Block.
(Can be powered by +3.3V Standby power
if monitoring in low power states is
required.)
Analog Ground.
