51
IMON
A-O
Total load current monitoring output pin. It is used with the PSI# to properly handle the
dynamic phase switching for higher efficiency. IMON is limited to a max voltage of 1.1 V so
as not to damage the CPU input.
52
VID7
D-I/O
The voltage identification pin VID7, connects to CPU. (See Note 1)
53
VID6
D-I/O
The voltage identification pin VID6, connects to CPU. (See Note 1)
54
VID5
D-I/O
The voltage identification pin VID5, connects to CPU. (See Note 1)
55
VID4
D-I/O
The voltage identification pin VID4, connects to CPU. (See Note 1)
56
VID3/SVC
D-I/O
The voltage identification pin VID3, connects to CPU. (See Note 1)
57
VDD
P-I
+5V (nominal) supply pin for “l(fā)ower” voltage circuits.
58
VID2/SVD
D-I/O
The voltage identification pin VID2, connects to CPU. (See Note 1)
59
VID1/PVI_SVI#
D-I/O
The voltage identification pin VID1, connects to CPU. (See Note 1)
60
VID0
D-I/O
The voltage identification pin VID0, connects to CPU. (See Note 1)
61
SIFDAT/DVC[1]
I2C-O
GP-OUT
Serial data output pin for the SIF bus.
When in GPO mode, this pin serves as the DVC[1] logical output and requires a 4 k
Ω
pull-down resistor.
62
SIFCLK/DVC[0]
I2C-O
GP-OUT
Serial clock output pin for the SIF bus.
When in GPO mode, this pin serves as the DVC[0] logical output and requires a 4 k
Ω
pull-down resistor.
63
SMBCLK
A-I/O
Clock input pin for the system management bus and is compliant with the SMBus
specification.
64
SMBDAT
A-I/O
Data input pin for the system management bus and is compliant with the SMBus
specification.
