**540 (Spartan) Super7 2D/3D Ultra-AGP Single C.S.<11/30/99
***Info:
The single chipset, SiS540, provides a high performance/low cost
Desktop solution for the Super Socket 7 series CPUs based system by
integrating a high performance North Bridge, advanced hardware 2D/3D
GUI engine and Super-South bridge. In addition, SiS540 provides
system-on-chip solution that complies with Easy PC Initiative which
supports Instantly Available/OnNow PC technology, USB, Legacy Removal
and Slotless Design and FlexATX form factor.
By integrating the Ultra-AGP technology and advanced 128-bit graphic
display interface, SiS540 delivers high performance and up to 2 GB/s
memory bandwidth. Furthermore, SiS540 provides powerful slice layer
decoding DVD accelerator to improve the DVD playback performance. In
addition to providing the standard interface for CRT monitors, SiS540
also provides the Digital Flat Panel Port (DFP) for a standard
interface between a personal computer and a digital flat panel
monitor. To extend functionality and flexibility, SiS also provides
the "Video Bridge" (SiS301) to support the NTSC/PAL Video Output,
Digital LCD Monitor and Secondary CRT Monitor, which reduces the
external Panel Link transmitter and TV-Out encoder for cost effected
solution. SiS540 also adopts Share System Memory Architecture which
can flexibly utilize the frame buffer size up to 64MB.
The "Super-South Bridge" in SiS540 integrates all peripheral con-
trollers/accelerators/interfaces. SiS540 provides a total commun-
ication solution including 10/100Mb Fast Ethernet for Office
requirement. SiS540 offers AC’97 compliant interface that comprises
digital audio engine with 3D-hardware accelerator, on-chip sample rate
converter, and professional wavetable along with separate modem DMA
controller. SiS540 also provides interface to Low Pin Count (LPC)
operating at 33 MHz clock which is the same as PCI clock on the host,
and dual USB host controller with four USB ports that deliver better
connectivity and 2 x 12Mb bandwidth.
The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the
Ultra DMA33/66 function that supports the data transfer rate up to 66
MB/s. It provides a separate data path for two IDE channels that can
eminently improve the performance under the multi-tasking environment.

**W83C553F System I/O Controller With PCI Arbiter c:sep95
***Info:
The W83C553F Enhanced System I/O (SIO) Controller with PCI Arbiter is
a highly integrated device intended for use in any Peripheral
Component Interconnect (PCI) system, supporting x86 or PowerPC
(non-x86) type microprocessors. It supports all PCI 2.1 compliant CPU
bridge implementations and directly interfaces with PCI and ISA
industry standard buses, including two direct drive IDE channels
supporting up to four peripherals.
The W83C553F is a universal PCI device which can be used with many
CPU-to-PCI bridge solution. The W83C553F includes 32-bit ISA DMA
addressing (rather than 24-bit) to simplify its use in systems using
re-compiled versions of 32-bit operating systems (such as Windows NT
running on PowerPC, Alpha, or other RISC CPU).
The peripheral controller integrated into the W83C553F includes two
enhanced seven channel 82C37A 32-bit DMA controllers that support fast
DMA transfers with a four byte line buffer to isolate the PCI bus from
the ISA bus, enhancing performance. Both DMA controllers support
scatter/gather data transfer capability.
The W83C553F Enhanced SIO controller provides the bridge between the
PCI bus and the ISA expansion bus. It also integrates a PCI bus master
IDE controller, an eight master PCI arbiter (which may be disabled if
desired) and many of the common I/O functions found in today's ISA
based PC systems. The W83C553F incorporates the logic for a complete
PCI interface (master and slave) and ISA interface (master and
slave). Also included is PCI and ISA arbitration, 14 level interrupt
controller, a 16-bit BIOS timer, three programmable counter/timers,
non-maskable-interrupt (NMI) control logic and register support for
power management break events.
The built-in Enhanced PCI IDE Controller is a highly integrated dual
port controller, providing a high performance data path between IDE
devices and the PCI bus. Four IDE chip select signals provide
accessing of up to four devices. Each device has its own programmable
registers for selecting 16-bit and 32-bit data pipelined transfer
rates, read-ahead and posted writes. A large 64 Byte DMA FIFO buffers
data to and from the IDE disks enabling the integrated scatter/gather
DMA controller to efficiently perform zero wait state burst transfers
across the PCI bus when enough data is available in the FIFO. Bus
master IDE significantly improves the overall system performance of a
multi-master PCI configuration by greatly reducing the bus and CPU
utilization required for the disk and CD-ROM interface. Burst data
transfers at 33 MHz can be sustained at 132 MB/s on the PCI bus.
The integrated bus-mastering PCI-IDE core is the original Sonata
W83789F core with some modification of interrupt routing. This
controller is fully compliant to Intel's Bus-Mastering Controller and
SFF8038i specifications. BIOS support has been incorporated in all the
leading BIOS companies' software. Driver software, previously tested
and qualified for the W83789F, is available from Winbond Systems
Laboratory for all major operating systems, including recompiled
PowerPC versions.
