**Quote style:
To avoid  thousands of quote marks  and colliding with quote  marks in
the  text, I  have used  a modified  quotation style.   Anything in  a
section  titled "Info:"  or "Features:"  is a  quote from  a datasheet
unless otherwised stated in that  section.  In these sections anything
inside  [] is  an  annotation and  not part  of  the datasheet  unless
otherwise stated in that section.

Under any other section, the text is my own unless indicated with "".

Also  this document  does not  contain the  entire datasheet  for each
chip, usually only the first few pages are included to give an outline
of it. Some datasheets are 100s of pages other are only 1.

***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.
