**VL82C386-SET     TOPCAT 386DX PC/AT-Compatible Chip Set            ?
***Info:
The TOPCAT 386DX  chip set from VLSI Technology, Inc.,  is a very high
integration chip set  for use in the design  of PC/AT-compatible based
systems.    This   chip  set   is   intended   for  use   in   80386DX
microprocessor-based systems with clock speeds form 16 to 33 MHz.

The  TOPCAT 386DX  chip  set  provides design  engineers  with a  very
flexible, high-  performance, low-cost  board design solution  for IBM
PC/AT-compatible desktop, laptop, portable, and hand-held computers.

The  TOPCAT 386DX  three-device chip  set has  been designed  with the
highest  integration  consistent  with economic  and  reliable  system
design. It provides  a complete board design using  only 10 non-memory
devices including the microprocessor.

VLSI's The TOPCAT 386DX chip set was designed with seven goals.
o   lowest system board cost
o   Smallest board area requirement
o   highest performance in both cached and non-cached systems
o   single board design for:
    - 16 to 33 MHz operation
    - Cache or non-cache
    - 1M byte to 64M byte memory using 256K, 1M, and 4M bit DRAM
    - Laptop or desktop applications
o   Full hardware LIM EMS 4.0 support for the highest possible 
    performance
o   Built-in, in-circuit test modes for easy board level testing.
o   the VL82C330A interfaces to the VL82C335 "look-aside" Cache 
    Controller

with  VLSI's TOPCAT  386DX  chip set,  you  can be  assured that  your
high-performance system design needs are met.
