Electrical Specifications
Notes:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
The V
TT
referred to in these specifications refers to instantaneous V
TT
.
3.
Refer to the processor I/O Buffer Models for I/V characteristics.
4.
Measured at 0.1*V
TT
.
5.
Measured at 0.9*V
TT
.
6.
For Vin between 0 V and V
TT
. Measured when the driver is tristated.
7.
This is the measurement at the pin.
Notes:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
Measured at 0.2*V
TT
.
3.
V
OH
is determined by value of the external pullup resistor to V
TT
. Please refer to platform design guide for
details.
4.
For V
IN
between 0 V and V
OH
.
5.
This is the measurement at the pin.
Notes:
1.
These parameters are based on design characterization and are not tested.
2.
All DC specifications for the SMBus signal group are measured at the processor pins.
3.
Platform designers may need this value to calculate the maximum loading of the SMBus and to determine
maximum rise and fall times for SMBus signals.
