7.4.2.2. Voltage Data Format
The W83627UHG can return five (5) voltage values through the SST interface. The voltage data
format is 16-bit two’s-complement binary. The relation between the 2-byte data and the monitored
voltage is listed below:
1) CPUVCORE (pin 101) = Decimal[2-byte data by GetVoltVccp() ] / 1024 volts
2) 5VCC (pin 12) = Decimal[2-byte data by GetVolt5V()] / 1024 volts
3) “+12V” = Decimal[2-byte data by GetVolt12V()] / 1024 / ((R1+R2) / R2) volts
4) “+3VCC” = Decimal[2-byte data by GetVolt3p3V()] / 1024 / ((R3+R4) / R4) volts
VIN1 (pin 99) is connected as shown below:
5) “+2.5V” = Decimal[2-byte data by GetVolt2p5V()] / 1024 / ((R5+R6) / R6) volts
VIN0 (pin 100) is connected as shown below:
VIN2 (pin 98) is connected as shown below:
