**Intro:
The information contained within this file should not be considered
100% correct. Where possible information has been taken from
datasheets, however even this info may be incorrect. The datasheets
state what the chip should do, not what they actually do. This is,
compounded further by different revisions of chips.
This document will never be complete, and I have no intention of
finding every datasheet for every chip set. Some of the chip sets
listed are from later systems in the PIII/P4/Athlon era. There are
many websites with information on these chip sets and these entries
will likely not be expanded upon. The focus of this document is early
PC/XT to Pentium chip sets. There are few sites that clearly illu-
strate this information, and how they relate to each other.
I aim to prioritize cataloging significant, rare or otherwise
interesting chip sets.
BTW the reason I wrote all of this down, is so that I could FORGET it.
Basically I needed to free up some RAM. I've a head full of arcane
snippets of information on this subject. I don't want to end up a
crazy old man ranting random disjointed information ("The C&T CS8220
came before the CS8221 you KNOW!") to disinterested passersby, unable
to see how senile I've become. A side benefit, this might be useful to
someone else:-)

**85C461 ISA 386DX/486 Single Chip [no datasheet] ?
***Notes:...
**85C471/407 Green PC ISA-VLB 486 Single Chip <94
***Info:
The SiS85C47l, single chip controller supports Intel's 80486DX2/DX/
SX/SL Enhanced, P24D/P24T/P24C CPU, Cyrix's Cx486S2 (M6/M7) CPU and
AMD's Am486DXL/DXLZ CPU.
The Si885C471 is a high performance, 100% PC/AT compatible single chip
controller, designed for cached/non-cached P24D/P24T/P24C, M6/M7 or
486 PC systems. The high integration of the powerful cache controller,
the DRAM controller, the CPU interfaces, the bus controller, the data
buffers and the peripheral controllers provides an easy and economical
solution for compact board manufacturing.
In addition to supporting burst reads for the cache line fills of the
CPU, the SiS85C47l is capable of accepting burst write data of the
CPU's internal cache dirty line(s) during CPU write-back cycles. The
support of the CPU burst write cycle is optional through the control
of the Configuration Registers. The SiS85C471 supports the cache size
up to l MB and the DRAM size up to 128 MB.
The SiS85C471 has a built-in cache controller which supports direct
mapped write-through/write-back cache. The programmable AT-bus clock
supports are compatible with AT-bus timing requirements for different
PC systems.
In addition, the local bus interfaces, the integration of the DMA
Controllers, Interrupt Controllers and Timers/Counters are designed to
be a higher performance, more compact, and more cost-effective product
for a P24D/PZ4T/PZ4C, 486SX/DX/DX2/SL-Enhanced, Am486DXL/DXLZ, or a
Cx48682 (M6/M7) PC/AT system.
The SiS85C47I provides power saving features to allow a system,
through the control of BIOS, to reduce the CPU clock frequency from
50MHz down to 0 MHz(STOP CLOCK) when the system is idle.
To support the SL-Enhanced 486, M6/M7, P24D/P24T/P24C's Am486DXL/DXL2
STPCLK/SMI features, the SiS85C47l also implements the corresponding
logics to support STPCLK /SMI for power saving.
The SiSSSC471 supports the VL-Bus applications including (1) CPU
accesses VL-Bus targets, (2) VL-Bus master mode, and (3) DMA or ISA
master accesses VL-Bus targets.
The SiS85C471 provides flexible ways in configuring the system
depending on whether cache or VESA local bus masters are
supported. The different configurations require different numbers of
external components.
