**WD76C20x   Floppy, RTC, IDE and Support Logic Device       <11/25/91
***Info:
GENERAL DESCRIPTION

The  WD76C20 is  a member  of  the WD7600  chip set  which provides  a
cost-effective,  power-efficient   solution  to  PC   systems  design,
especially those  relating to "lap-top" devices. The  set includes the
WD76C10, the WD76C20, and the WD76C30 as shown in Figure 1-1. Together
these chips  provide all necessary  logic to build a  fully integrated
system board for several  varieties of IBM PC/AT compatibles including
systems using 80286, 80386SX, and 80C286 processors.

As  part  of  this  chip  set, the  WD76C20  provides  these  integral
functions:
o Bus Interface Logic
o IDE Interface
o Chip Select Logic
o Floppy Disk Controller
o Real Time Clock
o Suspend/Resume Logic

The Floppy  Disk Controller (FDC) component  provides necessary timing
and signalling between the host  processor peripheral bus and a floppy
disk drive through a cable connector.

The Real Time Clock  component provides calendar and clock information
for the system.

The IDE Interface  controls buffering between the system's  AT Bus and
PC/AT compatible IDE drive interface.

The  Bus  Interface  Logic  controls  buffering of  data  between  the
system's AT Bus and the WD76C20.

The  Chip Select  Logic section  provides decoding  for  selected chip
functions both within the WD76C20 and on the PC/AT motherboard.

Suspend/Resume  Logic provides  support  for chip  set power-down  and
resume sequences.
