Description
SMBus Bidirectional Serial Data. Open drain, requires SMBus pullup.
SMBus Serial Clock Input. Open drain, requires SMBus pullup.
Ground Pin.
3.3 V ? 10%.
General-purpose Open-drain Digital Input/Output. Frequently used for
switching load line resistors into VR load line circuitry or for switching LEDs
using external FETs.
General-purpose Open-drain Digital Input/Output. Frequently used for
switching load line resistors into VR load line circuitry or for switching LEDs
using external FETs.
PECI Input to Report CPU Thermal Information. PECI voltage level is
referenced on the V TT input.
Voltage Reference for PECI. This is the supply voltage for the PECI interface
and must be present to measure temperature over the PECI interface. This
voltage is also monitored and presented in Register 0x1E.
Fan Tachometer Input to Measure Speed of Fan 3 (Open-drain Digital Input).
Pulse-width Modulated Output to Control Fan 2 Speed. Open drain requires
10 k W typical pullup. Digital Output (Open Drain). This pin can be
reconfigured as an SMBALERT interrupt output to signal out-of-limit
conditions.
Fan Tachometer Input to Measure Speed Of Fan 1 (Open-drain Digital Input).
Fan Tachometer Input To Measure Speed Of Fan 2 (Open-drain Digital Input).
Pulse-width Modulated Output to Control Fan 3 Speed. Open drain requires
10 k W typical pullup. If pulled low on powerup, the ADT7490 enters address
select mode, and the state of Pin 14 (ADDR SELECT) determines the
ADT7490 slave address.
Fan Tachometer Input to Measure Speed of Fan 4 (Open-drain Digital Input).
May be reconfigured as a bidirectional THERM pin. Can be connected to the
PROCHOT output of the processor, to time and monitor PROCHOT assertions.
Can be used as an output to signal overtemperature c onditions o r for clock
modulation purposes. Active Low Digital Output. The SMBALERT pin is used to
signal out-of-limit comparisons of temperature, voltage, and fan speed. This is
compatible with SMBus alert. Can also be used at device powerup to assign
SMBus address.
Negative Connection for Remote Temperature Sensor 2.
Positive Connection to Remote Temperature Sensor 2.
Negative Connection for Remote Temperature Sensor 1.
Positive Connection to Remote Temperature Sensor 1.
Monitors Current Output of Analog Devices ADP319x family of VRD10/VRD11
controllers.
Monitors 5.0 V Supply Using Internal Resistor Dividers.
Monitors 12 V Supply Using Internal Resistor Dividers.
Monitors 2.5 V Supply Using Internal Resistor Dividers. Alternatively, this pin
can be reconfigured as a bidirectional THERM pin. Can be connected to the
PROCHOT output of the processor to time and monitor PROCHOT assertions.
Can be used as an output to signal overtemperature conditions or for clock
modulation purposes.
Monitors CPU V CC Voltage (to maximum of 3.0 V). All voltage inputs can
have their resistor dividers removed allowing for full-scale input of 2.25 V of
the ADC channel.
Pulse-width Modulated Output to Control Fan 1 Speed. Open drain requires
10 k W typical pullup. Also functions as the output for the XNOR tree test
enable mode.
