The NCT5585D 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 NCT5585D provides both high accuracy current mode sensing and low cost thermistor mode sensing. It also supports Nuvoton’s SMART FAN^TM I and SMART FAN^TM IV algorithms for fan speed control.

As for PC peripherals, the NCT5585D has KBC, 1 UART and GPI/O.

The NCT5585D implements Intel® PECI, AMD® SB-TSI interface, Intel® S0iX glue logic, Port 80 diagnostic messages on both LPC & eSPI interface, LED control via GPI/O outputs to indicate system power states, and power saving control function to further reduce power consumption in the S5 state.

The NCT5585D supports both LPC & eSPI interface to communicate with chipsets.
