Supports ATA 133.
Supports full speed burst transfers on the ATA bus.
Supports software-controlled ATA bus tri-state.
Supports device specific timing registers.
Supports device read-ahead and write-ahead capability under Virtual DMA.
1.2.4
Other Features
Features one 256-byte FIFO (32-bit x 64 deep) per IDE channel for host reads and writes.
Features ATA to PCI interrupt masking.
Features command buffering from the PCI to ATA.
Features Virtual DMA: Bus master transfer on the PCI bus and PIO transfer on the ATA bus.
Features Watch Dog Timer for fault resiliency.
1.3 SiI 0680A Technical Description
The SiI 0680AA is available in a 144-pin LQFP (Thin Quad Flat Package) including more ground pins in order to
accommodate the new higher data transfer rate specified in the ATA/ATAPI-6 specification. The chip has an
internal phase lock loop that will provide the 100/133MHz (selectable) internal clock, allowing a data transfer rate of
100/133MB/sec (selectable) on ATA interface. A built-in 80-pin cable detector provides users the ability to
determine whether a cable can support the latest Ultra ATA/100/133 (selectable) transfer rate. The SiI 0680A is
capable of supporting Native mode, external BIOS, Enhanced IDE mode (ultra DMA and multiword DMA mode) and
PIO mode.
1.4 References
For more details about the ATA technology, the reader is referred to the following industry specifications:
ATA/ATAPI-6 (at time of publication, ATA/ATAPI-6 has not been formally approved)
PCI Local Bus Specification Revision 2.2
Advanced Power Management Specification Revision 1.0
PCI IDE Controller Specification Revision 1.0
Programming Interface for Bus Master IDE Controller, Revision 1.0
1.5 Functional Description
SiI 0680A is more than a PCI-to-ATA bridge chip that transfers data between the PCI bus and storage media (e.g
hard disk drive, etc) over the ATA bus. As a host controller, it also performs functions associated with the host,
such as storing configuration information, and processing data for errors. The SiI 0680A680A can be described in
the following functional blocks:
PCI Interface. Provides the interface to any system that has a PCI bus. Instructions and system clocks are based
on this interface.
ATA Interface. Two separate channels (Primary and Secondary) to access storage media such as hard disk
drives, CD-ROM’s etc.
Controller Interface. Additional hardware interface for controlling and configuring the Host Controller.
