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

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.
