**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.
