**CS8230   386/AT                   (82C301/302/303/304/305/306)cFeb87
***Notes:...
***Info:...
***Configurations:
CS8230-16 is a 16Mhz set
CS8230-20 is a 20Mhz set 
CS8230-25 is a 25Mhz set 

Configurations:
82C301 BUS CONTROLLER 
82C302 PAGE/INTERLEAVE MEMORY CONTROLLER 
82A303 HIGH ADDRESS BUFFER 
82A304 LOW ADDRESS BUFFER 
82B305 DATA BUFFER 
82A306 CONTROL BUFFER 
and
82C206

also sometimes the 82C296 instead of the 82C206.

Note that different speeds use slightly different parts no:

82A306    82A306    82A306 

"82A305" *may* be a typo.

Parts are often marked:
CHIPS P82C301C 20Mhz or
CHIPS P82C302C 20Mhz

The 'C' at the end of the part *may* refer to parts that don't support
the 387

***Features:
o   100% IBM PC AT compatible 
o   Tightly coupled 80386 interface 
    - Designed to interface directly with the 80386 
    - Supports 16, 20 and 25MHz operation 
o   Operates in page mode, with interleave memory subsystem 
o   Independent clock to support correct AT bus timing 
o   Provides flexible processor clock selection 
o   Supports staggered and non-staggered refresh 
o   A complete 386/AT requires only 40 IC's plus memory 
o   Flexible Memory Architecture 
    - Supports memory configuration of up to 16MB 
    - Programmable wait states 
    - Supports 256K and 1MB DRAMs 
    - Supports page mode access with interleaved memory banks 
    - Supports zero wait state read hit operation 
    - Supports shadowing of BIOS EPROMs for efficient BIOS execution
