**82497/492 Cache Controller / Cache RAM (for P54 Pentium) <Nov94
***Notes:
Date source: 1995_Intel_Pentium_Processors_and_Related_Components.pdf
Information taken from:
1995_Intel_Pentium_Processors_and_Related_Components.pdf*
8249x Cache controllers.pdf**
>* Datasheet dated Nov'94

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.

**VL82C113 SCAMP Combination I/O chip ?
***Info:
The VL82C113/VL82C113A SCAMP Combination I/O chip, when used with VLSI
SCAMP chips, allows designers to implement a very cost-effective
minimum chip count motherboard. This chip combines a keyboard
controller and a real-time clock with the address registers/buffers
and buffers which are normally required in PC/AT-compatible systems.
The VL82C113/VL82C113A features an AT-compatible keyboard controller
with integrated PS/2 mouse support and a 146818A-compatible real-time
clock. In addition, the VL82C113/VL82C113A has 64 additional bytes of
battery-backed CMOS RAM for use in extended system setup.
