Controller IC Chip - NUVOTON NCT6779D 6779 Chip for laptop - Integrated Laptop Chip (Code 1-CHIP0809)

Controller IC Chip - NUVOTON NCT6779D 6779 Chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0809)

The NCT6779D is a member of Nuvoton’s Super I/O product line. The NCT6779D monitors several critical parameters in PC hardware, including power supply voltages, fan speeds, and temperatures. In terms of temperature monitoring, the NCT6779D adopts the Current Mode (dual current source) and thermistor sensor approach. The NCT6779D also supports the Smart Fan control system, including “SMART FANTM I and SMARTFANTM IV, which makes the system more stable and user-friendly. The NCT6779D provides two high-speed serial communication port (UART), which includes a 16-byte send/receive FIFO, a programmable baud rate generator, complete modem-control capability, and a processor interrupt system. The UART supports legacy speeds up to 115.2K bps as well as even higher baud rates of 230K, 460K, or 921K bps to support higher speed modems. The NCT6779D supports the PC-compatible printer port (SPP), the bi-directional printer port (BPP), the enhanced parallel port (EPP) and the extended capabilities port (ECP). The NCT6779D supports keyboard and mouse interface which is 8042-based keyboard controller. The NCT6779D provides flexible I/O control functions through a set of general purpose I/O (GPIO) ports. These GPIO ports may serve as simple I/O ports or may be individually configured to provide alternative functions. The NCT6779D supports the Intel® PECI (Platform Environment Control Interface) and AMD® SB-TSI interface. The NCT6779D supports AMD® CPU power on sequence, and it also supports Intel® Deep Sleep Well glue logic to help customers to reduce the external circuits needed while using Deep Sleep Well function. The NCT6779D supports to decode port 80 diagnostic messages on the LPC bus. This could help on system power on debugging. It also supports two-color LED control to indicate system power states. The NCT6779D supports Consumer IR function for remote control purpose. It also supports Advanced Power Saving function to further reduce the power consumption while the system is at S5 state. The configuration registers inside the NCT6779D support mode selection, function enable and disable, and power-down selection. Furthermore, the configurable PnP features are compatible with the plug-and-play feature in Windows, making the allocation of the system resources more efficient than ever.

Meet LPC Specification 1.1 Support AMD power on sequence Support LDRQ# (LPC DMA), SERIRQ (Serialized IRQ) Integrated hardware monitor functions Support DPM (Device Power Management), ACPI (Advanced Configuration and Power Interface) Programmable configuration settings Single 24-MHz or 48-MHz clock input Support selective pins of 5 V tolerance
