Question
I'm trying to access the Winbond 83627DHG-P IO chip on the motherboard X8SIL. We want to use the LMsensor. Do you have the offset codes for the smbus?

Answer
Bus Type = ISAIO/SMBus
One W83627DHG-P

Windbond W83627DHG-P, Slave Address=0x2d (0x5a in 8-Bit format)
OR IndexReg=A15, DataReg=A16
=============================================================

Fan1 Fan Speed, Bank 0, Offset 0x29 RPM = 1350000/8/Data

Fan2 Fan Speed, Bank 5, Offset 0x53 RPM = 1350000/8/Data

Fan3 Fan Speed, Bank 0, Offset 0x28 RPM = 1350000/8/Data

Fan4 Fan Speed, Bank 0, Offset 0x3f RPM = 1350000/8/Data

Fan5 Fan Speed, Bank 0, Offset 0x2a RPM = 1350000/8/Data

CPU Voltage, Bank 0, Offset 0x20 Voltage = Data* 0.008

-12V Voltage, Bank 0, Offset 0x26 Voltage = ((Data*0.008-2.048)/(10./242.))+2.048

+12V Voltage, Bank 0, Offset 0x21 Voltage = Data* 0.008/ (10./66.2)

AVCC Voltage, Bank 0, Offset 0x22 Voltage = Data* 0.016

3.3Vcc Voltage, Bank 0, Offset 0x23 Voltage = Data* 0.016

DIMM Voltage, Bank 0, Offset 0x24 Voltage = Data* 0.008

+5V Voltage, Bank 0, Offset 0x25 Voltage = Data* 0.008/ (10./40.)

+3.3VSb Voltage, Bank 5, Offset 0x50 Voltage = Data* 0.016

VBAT Voltage, Bank 5, Offset 0x51 Voltage = Data* 0.016

CPU Temperature, Bank 1, Offset 0x50 Temperature = Data

System Temperature, Bank 2, Offset 0x50 Temperature = Data

Chassis Intrusion, Bank 0, Offset 0x42, BitMask 0x10 1 = Bad, 0 = Good
(Clear Bit: Bank 0, Offset 0x46, BitMask 0x80)


Power Supply Failure, GP23(From W83627DHG-P) 1 = Good, 0 = Bad
