5V

Measured temperatures

Ambient temperature

The temperature is measured with a thermistor.

4.19SMB Hardware Monitor

In addition to the SuperIO hardware monitor you can also connect a SMBus hardware monitor. This chip enables you to control different voltages, temperatures and rotation speeds in legacy-free-designs where the SuperIO is not supported.

Hardware monitor:

Winbond W83L786R

Controlled voltages

VBAT

3.3V

12V

5V

Measured temperatures

Ambient temperature

The temperature is measured with a thermistor.

Fan interface

For evaluation and control of the revolution speeds please refer to chapter 4.18.4.

4.20Serial EEPROM on SMBus

For testing purposes a serial EEPROM (4kBit) is connected to the SMBus. To avoid address conflicts, the address can be selected with dip switch SW1101.

4.21Serial EEPROM on I2C-Bus

For testing purposes a serial EEPROM (4kBit) is connected to the I2C bus. To avoid address conflicts, the address can be selected with dip switch SW1102.
