**CS8238   CHIPS/280 & 281 (386 MCA)(82C321/322/325/223/226)   c:Aug89
***Info:
CHIPS/280 is a  7-device, enhanced CMOS implementation of  most of the
system logic  necessary to implement personal  computers compatible to
IBM PS/2 Model 70/80. CHIPS/280  enables OEMs to offer compatible PS/2
models  70/80, that are  more integrated  and superior  in performance
than IBM's Model 70/80.

CHIPS/280  includes  the  CS8238  System  Logic  CHIPSet,  the  82C607
Multi-Function  Controller  with   Analog  Data  Separator  and  16550
compatible  serial  port,   and  the  Enhanced  Gate-Level  Compatible
82C451/452  VGA chip  as  indicated in  Figures  1a and  lb [see  data
sheet].  With these  7 VLSI  devices, it  requires only  59 additional
components  plus  memory to  implement  compatible  PS/2 Models  70/80
superior to IBM's models.

CHIPS/280  is  designed  to  maximize  the performance  of  the  80386
microprocessor by  coupling it to a  high performance page/interleaved
memory sub-system.  The maximum page  size supported by  the CHIPS/280
architecture  is 16  KBytes when  1  Mbyte DRAMs  are used  (16 MB  of
onboard  Memory) and  the four  way interleaved  mode of  operation is
selected. When executing within a page, the DRAM memory sub-system can
execute at the  same speed as the processor. To the  386, the mem- ory
sub-system appears as a 16 KByte direct mapped cache, using relatively
inexpensive DRAMs.  When operating  at 16, 20  or 25 MHZ,  the average
waitstate incurred is less than 0.7. Additionally, by using Shadow RAM
techniques, the  BIOS code  can also be  executed with near  zero wait
states.

In  addition  to  the  high performance  memory  interface,  CHIPS/280
supports a fast Matched Memory Cycle reducing the access time from 200
ns to  120 ns at 25 MHz.  CHIPS proprietary Fast VGA  cycle allows VGA
I/O accesses to be performed within 187.5 ns@ 16 MHz, 150 ns @ 20 MHz,
and 120 ns @ 25 MHz.

Regardless  of  the CPU  speed,  the  DMA  controller operates  at  10
MHz. Once the  DMA and the peripherals are tuned,  for example, with a
1:1  interleaving on  the Hard  Disk, CHIPS/280  continues  to deliver
dependable high performance.

**82497/492   Cache Controller / Cache RAM (for P54 Pentium)    <Nov94
***Notes:

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.
