Command Summary, continued.
7.4.2
7.4.2.1.
The W83627DHG temperature data format of both CPUTIN and SYSTIN is 16-bit two’s-complement
binary value. It represents multiple of 1/64°C in the temperature reading.
Table 1 shows some typical temperature values in 16-bit two’s complement format.
7.4.2.2.
The W83627DHG 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 100) = Decimal[2-byte data by GetVoltVccp() ] / 1024 volts
2) 3VCC (pin 12) = Decimal[2-byte data by GetVolt3p3V()] / 1024 volts
3) “+12V” = Decimal[2-byte data by GetVolt12V()] / 1024 / ((R1+R2) / R2) volts

Returns the 2-byte voltage data values for pin VIN2 (Pin 97). This pin should
be connected to +2.5V power through scaling resistors. Refer to 7.4.2.2
Returns the 2-byte voltage data values of CPUVCORE (Pin 100). This pin
should be connected to CPU power supply directly. The CPU power supply
voltage must not be higher than 2.048 volt
Returns a 10-byte voltage data value containing all the above listed five (5)
voltages
