**82C802G/GP     System/Power Management Controller (cached)      c:93
***Notes:...
***Info:
The  82C802G/GP  provides  a  highly  integrated  solution  for  fully
compatible,  high  performance  PC/AT  platforms.  This  chipset  will
support  486SX/DX/DX2/DX4 and  P24T microprocessors  in the  most cost
effective  and power  efficient  designs available  today.  For  power
users this  chipset offers optimum performance for  systems running up
to 50MHz.

Based  fundamentally  on  OPTi’s   proven  82C801  and  82C802  design
architectures,  the 82C802G/GP  adds additional  memory configurations
and  extensive power management  control for  the processor  and other
motherboard components.

The  82C802G/GP supports  the latest  in write-back  processor designs
from Intel, AMD, and Cyrix, as  well as supporting the AT bus and VESA
local  bus for  compatibility and  performance.  It  also  includes an
82C206  Integrated  Peripherals  Controller  (IPC), all  in  a  single
208-pin PQFP (Plastic Quad Plat Pack) package for low cost.

Power Management Block
Figure  2-1  [see  datasheet]   exemplifies  the  flexibility  of  the
82C802G/GP/82C602   GREEN   strategy.   System  designs   can   easily
accommodate  both SLe and  non-SLe CPUs.  If an  Intel non-SLe  CPU is
used. SMI#, SMIACT#, and FLUSH# are no connects. One design can easily
accommodate  both  types  of   processors  with  minimal  changes  for
upgrades.

**UM82C852     Multi I/O For XT                                    <91
***Info:
The  Multi-I/O  chip, UM82C852  is  an  integrated  chip of  UM82C450,
UM82C11, UM82C8167. This  chip is a Multi-I/O for  PC/XT and PS2 model
30.

The   82C450  asynchronous   communications  element   (ACE)  performs
serial-to-parallel  conversion   on  data  characters   received  from
peripheral  devices or  modems, and  parallel-to-serial  conversion of
data characters transmitted by the CPU. The complete status of the ACE
can  be read  at  any time  during  functional operation  by CPU.  The
information obtained  includes the type and condition  of the transfer
operations being performed and error conditions.

The  82C11  parallel  port  provides  the user  with  a  bidirectional
parallel data  port that fully  supports the parallel  Centronics type
printer.

The 82C8167 real time clock includes an addressable real time counter,
56 bits  of static RAM with  an on chip oscillation  circuit which can
generate the 32,768 Hz time base.

The 82C852 is packaged in a 68-pin plastic leaded chip carrier.
