**ET6000     "Cheetah" 486DX/SX Non-Cache System                <Apr92
***Info:
The  CHEETAH single  chip provides  high  integration and  a low  cost
solution  for  a  16,  20,  25,  33, and  50MHz  486/AT  based  system
design.  The CHEETAH  combined  with 82C206  or compatible  peripheral
controller offers  a 100% PC/AT  compatible system using less  than 10
components  plus  memory devices.  The  CHEETAH  is  available in  the
160-pin Plastic Quad Flat-pack package. The 1.0u high speed, low power
CMOS Technology  allows for substantial stability when  running at 25,
33, and 50MHz.

The CHEETAH includes  486 CPU control, AT Bus  Control, Page Mode DRAM
Control,  Asynchronous AT  Bus Clock  Generation, data  bus conversion
logic which performs the conversion necessary between the 8 and 16-bit
data paths, and Coprocessor Interface Logic to support Intel 487SX and
Weitek 4167.

The Cheetah  ET6000 is  a highly integrated  single chip  AT optimized
specifically for486 CPUs.  The emphasis of this chip  is to reduce the
cost   requirements   of   486  applications,   without   compromising
performance. Fast bursting can be achieved with 80ns DRAMs.

The  system  cost  is also  minimized  by  allowing  the use  of  slow
DRAMs. The  Burst Mode DRAM  control is implemented to  enhance system
performance.

The Cheetah is designed to be 100% compatible with the IBM PC/AT. With
its optimized Burst and DRAM design, enhanced features like Shadow RAM
BIOS, and  Concurrent Refresh; a high performance/low  cost 486/AT can
be implemented.

The info and features section have  been solely sourced from the first
source.   The  second source  provides  far  more detail.   Additional
information in the configurations section  and below have been sourced
from the second.

"Although the 82497 Cache Controller  is part of the Pentium processor
(735\90, 815\100, 1000\120, 1110\133) CPU-Cache Chip Set and the 82496
Cache  Controller is part  of the  Pentium Processor  (510\60, 567\66)
Chip  Set, the  two parts  are functionally  identical except  for the
differences noted in this section." - p491

Aside  from some  minor  differences in  pin  configuration, the  main
difference is the direct support  for 3.3V processors. This chipset is
still a 5V part. The cache operates at bus speed, max 66MHz.


This  chip was  used on  the Pentium  90MHz CPU  complexes of  Intel's
Xpress  platform.   Specifically  the BXCPUPENT90  (Single  90MHz,  16
82492s). Also found on IBM 9595/Server 500 Pentium 90MHz complexes.
