**CS4000 WinCHIPS (64200/84021/84025) c92
***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.

**F87000 Multi-Mode Peripheral Chip 11/23/93
***Info:
The F87000 Multi-Mode Peripheral Chip is a companion to the F8680A
PC/CHIP single-chip PC. By strapping pins to select the desired mode,
the F87000 device becomes one of four integrated peripheral chips that
extend the functionality of PC/CHIP.
Chips and Technologies, Inc. has designed the F87000 chip specifically
for use with the F8680A microchip to accommodate portable computing
devices and embedded control applications where integration,
conservation of board space, and power consumption are critical.
In PCMCIA card implementations, card buffering and isolation is
recommended for design robustness, especially in rugged use enviro-
nments. The buffering ensures that the PCMCIA card receives a strong
clean signal, while the isolation provides both the protection for
"hot card insertion" and is hardwired for turning off power to a card.
Hardware isolation, supported with Power Management SuperState code,
minimizes the system’s power consumption. PCMCIA card slots that are
not properly buffered and isolated run a high risk of a system crash/
failure if the cards are inserted/removed while the slot is powered.
The PC/CHIP F87000 is designed to be used in four modes.
o Mode 1 ---- Single PCMCIA card buffering support provides:
• 20-bit address buffer.
• 16-bit bidirectional data buffer.
• Buffering for five control signals.
o Modes 2 and 3 ---- Dual PCMCIA card buffering support provides:
• Individual address buffering (64MB each).
• Individual data bus buffering.
• Two OR gates.
o Mode 4 ---- Multifunctional mode provides:
• Keyboard circuitry interfacing to a 16 x 8 keyboard matrix.
• Clock divider conversion of 14.31818MHz to 1.8432MHz output
(divide by 7.77).
• Parallel printer port.
• IDE interface.
• 7-bit configuration ports plus external select for port
expansion.
