***Info:
Overview
The 82C898 provides a highly integrated solution for fully compatible,
high performance PC/AT platforms. The 82C898 supports 486SX/DX/DX2/DX4
and  P24T  microprocessors  in  the  most  cost  effective  and  power
efficient designs  available today. For  high-end system applications,
this  device offers  optimum  performance for  systems  running up  to
50MHz.  

Based  fundamentally  on  OPTi’s   proven  82C801  and  82C802  design
architectures,  the 82C898 adds  additional memory  configurations and
extensive  power  management  control  for  the  processor  and  other
motherboard components.

The 82C898  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 Flat Pack) for low cost.

Power Management
Figure  2-1   [see  datasheet]  exemplifies  the   flexibility  of  an
82C898/82C602-based designs GREEN strategy.  System designs can easily
accommodate both  SLe and non-SLe  CPUs.  If  an Intel non-SLe  CPU is
used, SMI#, SMIAOT#, and FLUSH# are no connects. One design can easily
accommodate  both  types  of   processors  with  minimal  changes  for
upgrades.
