**82C895         System/Power Management Controller (cached)   c:Sep94
***Notes:...
***Info:
Overview
The 82C895 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 82C895 adds  additional memory  configurations and
extensive  power  management  control  for  the  processor  and  other
motherboard components.

The  820895  supports the  latest  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-compatible  Integrated Peripherals Controller  (IPC). all  in a
single 208-pin PQFP (Plastic Quad Flat Pack) package for low cost.

2.1 Power Management

This block diagram [see  datasheet] exemplifies the flexibility of the
82C895/82C602 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 accomm-
odate 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.
