Description
The NCT6776D is a member of Nuvoton’s Super I/O series capable of monitoring critical parameters in PC hardware including power supply voltages, fan speeds and temperatures. The NCT6776D supports both high accuracy current mode sensing and low cost thermistor mode sensing. The NCT6776D also supports the Nuvoton SMART FAN&tr; I and SMART FAN&tr; IV algorithms for fan speed control.
The NCT6776D also provides decode of Port 80 diagnostic messages on the LPC bus, two-color LED control to indicate system power states, Consumer IR function for remote control purpose, and power saving control function to further reduce the power consumption in the S5 state.
