**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.

**VL82C325             VL82C386SX System Cache controller            ?
***Info:
The VL82C325  Memory Cache  Controller is  a high  performance; highly
integrated cache controller for systems  based on the VLSI Technology,
Inc.'s TOPCAT 386SX or SCAMP-LT chip sets. To implement a 32KB two-way
set associative cache subsystem, all  that is required is the VL82C325
and two 8K x 16 cache data  RAMs. The VL82C325 has been designed to be
an integral  part of the  TOPCAT386SX chip set. this  feature improves
the overall system  performance by reducing the number  of wait states
during non-cache cycles when compared  to cache controllers which must
pipeline all  cycles which  can not  be serviced  by reading  from the
cache  data  RAM.   The  VL82C320A TOPCAT  System  Controller  or  the
VL82C310 SCAMP  Controller, and  the VL82C325  operate in  parallel to
decode 386SX requests. The controller  starts decoding the 386SX cycle
simultaneously with  the VL82C325  and is  therefore able  to actually
start a  memory cycle  before a  miss indication  is generated  by the
VL82C325.
