**W83769          Local Bus IDE Solution                           <94
***Info:
GENERAL DESCRIPTION

The W83769  is a  high-performance, low-cost, highly  integrated logic
design  for IDE hard  disk applications  in PCI  (Peripheral Component
Interconnect)  local  bus systems.  It  provides  a  bridge between  a
standard  IDE  drive  and the  PCI  local  bus.  The W83769  is  fully
compatible  with the  ANSI ATA  3.0 specifications  for IDE  hard disk
operation  and the  PCI SIG  revision 2.0  specifications for  the PCI
local bus  protocol. Packaged in  a 100-pin PQFP, the  W83769 directly
supports the 32-bit PCI bus without requiring any external TTLs.

The W83769  operates at up to 50  MHz and provides a  full 32-bit data
path to the PCI bus. Doubleword read and write operations are provided
via  internal   control  and  conversion  logic.   Write  posting  and
read-ahead  allows CPU  memory  cycles to  run  concurrently with  IDE
cycles and improves the hard disk buffer-to-host transfer rate.

The IDE  drive interface timing  of the W83769 is  completely software
programmable,  including command  active/recovery  timing and  address
setup-hold   timing  for   each  drive.   The  device   supports  Fast
ATA/Enhanced  IDE  mode  3  timing  and IORDY  monitoring  for  better
performance.   The  W83769  directly  supports four  IDE  drives  with
170/1F0   dual   IDE  connectors.   The  IO base   addresses  of   the
primary/secondary  IDE connector  are exchangeable  by  power-on strap
option.
