NCT5577D

The NCT5577D 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 NCT5577D supports both high accuracy current mode sensing and low cost thermistor mode sensing. The NCT5577D also supports the Nuvoton SMART FAN™ I and SMART FAN™ IV algorithms for fan speed control.

The NCT5577D supports KBC, 1 UART and GPI/O.

The NCT5577D supports the Intel® PECI, AMD® SB-TSI interface, AMD® CPU power on sequence, and partial Intel® Deep Sleep Well glue logic to reduce external support circuitry needed for Deep Sleep Well capability.

The NCT5577D also provides two-color LED control via GPI/O outputs to indicate system power states, Consumer IR function for remote control purpose, and power saving control function to further reduce power consumption in the S5 state.
