The SiS963 MuTIOL® 1G Media I/O integrates one Universal Serial Bus 2.0 Host Controllers, the 1394a Controller, the Audio Controller with AC'97 Interface, the Ethernet MAC Controller w/ standard MII interface, three Universal Serial Bus 1.1 Host Controllers, the IDE Master/Slave controllers, and SiS MuTIOL® 1G technology. The PCI to LPC bridge, I/O Advanced Programmable Interrupt Controller, legacy system I/O and legacy power management functionalities are integrated as well.

The USB 2.0 Host Controller includes one high-speed mode host controller and three USB 1.1 host controllers. The high-speed host controller implements an EHCI interface that provides 480Mb/s bandwidth for six USB 2.0 ports. The three USB 1.1 host controllers implement an OHCI interface and each USB 1.1 host controller provides 12Mb/s bandwidth for two USB 1.1 ports. Each of six USB ports can be automatically routed to support a High-speed USB 2.0 device or Full- or Low-speed USB 1.1 device. Besides, each port can be optionally configured as the wake-up source. Legacy USB devices as well as over current detection are also implemented.

The integrated 1394a function complies with 1394 Open Host Controller Interface Specification 1.1, IEEE1394-1995 and IEEE 1394a-2000. The bus transfer rate of 100, 200, 400 Mbits/s is supported, and both Asynchronous and Isochronous data transfers are supported as well. With external 1394 physical layer chip, it can support up to three 1394 ports to connect with 1394 devices.

The Integrated AC'97 v2.2 compliance Audio Controller that features a 6-channels of audio speaker out and v.90 modem support. Additionally, the AC'97 interface supports 4 separate SDATAIN pins that is capable of supporting multiple audio codecs with one separate modem codec.

The integrated Fast Ethernet MAC Controller features an IEEE 802.3 and IEEE 802.3x compliant MAC with external LAN physical layer chip supporting full duplex 10 Base-T, 100 Base-T Ethernet, or with external Home networking physical layer chip supporting 1Mb/s & 10Mb/s Home networking. Additionally, 5 wake-up Frames, Magic Packet and link status changed wake-up function in G1/G2 states are supported. For storing Mac address, two schemes are provided: 1. Store in internal APC register or 2. Store in external EEPROM.

The integrated IDE Master/Slave controllers features Dual Independent IDE channels supporting PIO mode 0, 1, 2, 3, 4, and Ultra DMA 33/66/100/133. It provides two separate data paths for the dual IDE channels that sustain the high data transfer rate in the multitasking environment.

SiS963 supports 6 PCI masters and complies with PCI 2.2 specification. It also incorporates the legacy system I/O like: two 8237A compatible DMA controllers, three 8254 compatible programmable 16-bit counters, hardwired keyboard controller and PS2 mouse interface, Real Time clock with 512B CMOS SRAM and two 8259A compatible Interrupt controllers. Besides, the I/O APIC managing up to 24 interrupts with both Serial and FSB interrupt delivery modes is supported.

The integrated power management module incorporates the ACPI 1.0b compliance functions, the APM 1.2 compliance functions, and the PCI bus power management interface spec. v1.1. Numerous power-up events and power down events are also supported. 25 general purposed I/O pins are provided to give an easy to use logic for specific application. In addition, the SiS963 supports Deeper Sleep power state for Intel Mobile processor. For AMD processor, the SiS963 use the CPUSTP# signal to reduce processor voltage during C3 and S1 state.

A high bandwidth and mature SiS MuTIOL® 1G technology is incorporated to connect SiS MuTIOL® 1G North Bridge and SiS963 MuTIOL® 1G Media I/O together. SiS MuTIOL® 1G technology is developed into three layers, the Multi-threaded I/O Channels Layer delivering 1.2GB bandwidth to connect embedded DMA Master devices and external PCI masters to interface to Multi-threaded I/O Channels layer, the Multi-threaded I/O Packet Layer in SiS963 to transfer data w/ 1GB/s bandwidth from/to Multi-threaded I/O Channels layer to/from SiS MuTIOL® 1G North Bridge, and the Multi-threaded I/O Packet Layer in SiS MuTIOL® 1G North Bridge to transfer data w/ 1GB/s from/to memory sub-system to/from the Multi-threaded I/O Packet Layer in SiS963.
