**W83759/A/F/AF   Advanced VL-IDE Disk Controller                  <96
***Notes:...
***Info:
GENERAL DESCRIPTION

The  W83759A  is  an  advanced  version of  Winbond's  popular  VL-IDE
interface chip,  the W83759. The  W83759A retains all of  the features
and  compatibility of  the W83759  (the chip  meets the  ANSI  ATA 4.0
specification  for IDE  hard disk  operation and  the VESA  VL-Bus 2.0
specification  for  PC  local  bus devices)  while  incorporating  new
features  to   meet  Enhanced  IDE,  SFF-8011,   ATA-2,  and  Fast-ATA
specifications.

Supports Disk Capacity of Greater than 528 MB
The W83759A's  driver can handle remapping  from BIOS CHS  mode to HDD
LBA mode.  This scheme  enables users  to break the  528 MB  per drive
barrier, allowing  full use  of BIOS INT13  CHS information  in drives
with a capacity of up to 8.4 GB.

High Speed Host Transfer Rate
The W83759A supports  Enhanced IDE PIO mode 3 and Fast  ATA PIO mode 3
and 4  timing; jumper  settings or driver  programming can be  used to
select  the PIO  mode  and a  33  or 50  MHz  VL-Bus clock.  Different
programming timing  can be selected  for different drives in  the same
system. The burst transfer rate is shown in the following table.

ATA PIO  IDE COMMAND CYCLE  BURST TRANSFER RATE  IORDY THROTTLE 
MODE     TIME (nS)          (MB/sec)             CONTROL
0 	 600  		    3.33 		 Option
1 	 383 		    5.22 		 Option
2 	 240 		    8.33 		 Option
3 	 180 		    11.1 		 Required
4 	 120 		    16.6		 Required

Dual IDE Channels
Like  the  W83759,  the  W83759A  supports  a  secondary  IDE  address
(170h-177h/376h)  and  IRQ15  for  applications with  four  hard  disk
drives.  Additionally,  the  primary  and secondary  channels  can  be
independently  enabled  or disabled  by  jumper  settings or  software
programming.

Non-disk IDE Peripherals
Because  the command  cycle can  be programmed  individually  for each
drive and  dual IDE channels  are supported, non-disk  IDE peripherals
(such  as an  ATAPI  CD-ROM or  tape  drive) can  be  attached to  the
secondary  IDE without  affecting the  transfer rate  of the  ATA disk
drive.  Sales of ATAPI  IDE CD-ROMs  are expected  to grow  rapidly as
these devices become a standard part of many users' desktop PC setup.

The W83759A provides all  of the next-generation ATA-IDE requirements,
including  support for  high  capacity disk  drives,  high speed  host
transfers, multiple IDE peripherals,  and non-disk IDE peripherals. It
makes high-performance, low-cost, easy-to-use IDE machines possible.

The  W83759A is  pin-to-pin backward  compatible with  the  W83759. In
addition  to  the  advanced  features  described  above,  the  W83759A
supports  automatic   power-down,  standby,  and   suspend  APM  power
management states for green PC applications. This new chip is packaged
in a 100-pin QFP.

The table below compares the W83759 and W83759A:
