**CS8283 LeAPset-sx (82C841/82C242/82C636) c:Mar90
***Info:
The LeAPset CS8283 CHIPSet comprises highly integrated applications
specific integrated circuits that emulate the control logic of IBM PC
AT-compatible computers. Additionally, this CHIPSet provides
functions designed specifically for the laptop computer environment.
The CS8283 CHIPset, which supports the 386sx microprocessor, comprises
the following devices:
- the 82C841. This device includes a CPU/bus, page/interleave, and EMS
memory controller in addition to some laptop control features
- the 82C242. This chip includes data/address buffers and bus
conversion logic.
- the 82C636. This is the Power Control unit. It controls system power
and provides slow refresh DRAM support in standby mode.
- the 82C206. This device is an integrated peripheral controller.
- the 82C601. This is a multifunction controller that provides one
parallel and two serial port interfaces.
- the 82C455. This is a VGA-compatible flat panel control that
supports CRT, LCD, plasma and electro-luminescent displays.
- the 82C765. This is a floppy disk controller that is compatible
with the pud765A controller. It also contains a precision analog
data separator.
The CS8283 CHIPSet, which is compatible with the NEAT CHIPSet, is
designed specifically for use in laptop computers. However, it can be
used as the basis for a small footprint desktop computer in which
integration is the critical factor. Figure 1.1 [see datasheet] is a
block diagram of a typical implementation of the CS8283 in a laptop
environment.

***Info:
The WinCHIPS CHIPSet is a three chip set that includes the 64200
Wingine windows Accelerator and the CS4021 PC CHIPSet (two chips).
The WinCHIPS solution is specifically designed to enable systems
companies to offer modular PCs that allow the end user to upgrade both
microprocessor and graphics performance simultaneously. With WinCHIPS
CHIPSet based systems, PC users can easily migrate to more powerful
microprocessors and add or upgrade cache memory subsystems to achieve
maximum computing performance. Simultaneously, the WinCHIPS system
solution provides the ability of Wingine to scale graphics performance
in proportion to increasing microprocessor speed.
The two-chip systems logic elements of WinCHIPS support all 32-bit X86
microprocessors, including i80386DX, Am386, Super38600, Super38605,
i80486SX, i80468DX, and i80486DX2 microprocessors running at up to 50
MHz clock frequencies.
The WinCHIPS solution memory controller technology is designed to
offer the greatest performance for both cache-based and non-cache
based designs. Moreover, the flexible WinCHIPS architecture allows end
users to add a cache subsystem when upgrading to microprocessors
running 25 MHz or faster.
For non-cache 486SX designs, the WinCHIPS' patented page mode and page
interleaved memory controller supports DRAM Burst transfer for systems
running up to 25 MHz. For cache-based Super38605, and 486DX class
systems, WinCHIPS supports 64K to 512K of direct mapped, write back
cache memory. the WinCHIPS cache architecture integrates a write
buffer and zero wait state cache writes for maximum performance.
The WinCHIPS solution is unique in the industry in providing automatic
system wide performance benefits as end users upgrade to faster, more
powerful microprocessors. This is accomplished with the 64200 Wingine
Memory Bus Architecture which can support up to two banks of dual port
VRAM video memory on the microprocessor memory bus. Because the
required video memory control logic is integrated into the WinCHIPS
4021 Bus/DRAM Controller, video memory can be mapped directly into
main memory where it is linearly addressed by the microprocessor.
By allowing the processor to access video memory directly, graphics
functions performed by the processor, such as BIT BLTing, scale with
overall processor power. Hence the bottleneck inherent in today's
local abus and ISA bus graphics subsystems is removed. With the 64200
Wingine, the performance of the display scales correspondingly with
microprocessor power.
WinCHIPS is the industry's first CHIPSet to offer an advanced set of
hardware features designed to specifically support the SuperState
System Management Architecture found on the Super38605 micro-
processors.
