***Info:
The  UM82C210 is  an enhanced  PC/AT compatible  chip set  which  is a
highly integrated VLSI implementation of the control logic used in the
IBM AT. Due to its flexible architecture, the UM82C210 can be used, in
any  80286 based  systems.  The  UM82C210 chip  set consists  of three
chips  which  are:  UM82C211  (System  Controller),  UM82C212  (Memory
Controller), and UM82C215 (Data /Address Buffer).

The UM82C211,  System controller, provides all control  signals for AT
bus   including  bus   synchronization.  In   order  to   meet  timing
requirements  for different peripheral  boards, the  UM82C211 provides
programmable command delays and wait states.

The  UM82C212, Memory  Controller, provides  both  conventional memory
access and Page  Interleaved memory access. The UM82C212  also has LIM
EMS features that  support up to 8 MB of  on-board DRAMs. In addition,
the Shadow  RAM feature of  the UM82C212 allows faster  execution BIOS
codes.

The  UM82C215, Data/Address  Buffer, provides  buffering  and latching
functions between address buses and  data buses. It also generates the
parity bit and detects parity errors.

**VL82C3216        Bus Expanding Controller Cache with write buffer  ?
***Info:
The VL82C3216 Bus Expanding  Controller (BANC) Cache with Write Buffer
is  specifically  designed  to  provide a  high-performance,  low-cost
solution for  interfacing 386SX  PC/AT-compatible chip sets  to 386DX,
Am386DXL,  AM386DXLV,  486DX,  486SX,  or compatible  processors.  The
designs  may   be  entirely  new  systems  or   upgrades  to  existing
ones. Power management features also make this device ideal for laptop
computers  or  other battery  operated  systems.   The performance  is
achieved  through the  use of  a write  buffer structure,  an external
second level cache, prediction algorithms, and maximizing the internal
first level cache of the i486, if used.

The  high  level of  integration  is  entered  on the  VL82C3216.   It
controls all  functions between the  host processor bus and  the 386SX
local  bus.   in  addition  the  the  write  buffer  and  second-  and
first-level  cache controls,  the  VL82C3216  contains prediction  and
burst mode algorithms that take full advantage of the page mode design
of existing 386SX  system architecture.  Through the  use of pipelined
page mode accesses to system memory,  the VL82C3216 bursts data to and
from memory at rates  of up to 25 MB per  second. This provides 32-bit
memory performance at 16-bit memory costs.
