**82C556M/7M/8E Viper-N+ Viper Notebook Chipset c:96
***Notes:...
***Info:
The OPTi Viper-N+ chipset is the leading solution for PCI-based mobile
applications. Viper-N+ features leading edge power management
capability and flexibility for Intel Pentium 75/90/100/120 and Cyrix
6x86 processor based notebooks. The chipset incorporates desktop-like
performance features such as L1 and L2 cache support, a full 64-bit
DRAM controller and an integrated PCI controller, in a highly
integrated three chip set.
In terms of advanced power management, no chipset offers a more
effective, comprehensive or flexible feature set, allowing for maximum
performance with minimum power consumption for extended battery
life. In fact, for typical applications, Viper-N+'s power management
unit reduces power consumption by as much as 80%.
Viper-N+ offers the highest level of system integration, enabling the
lowest system cost and real estate requirement for Pentium-PCI
notebooks. A system without TTL is achievable with synchronous cache.
And, PCI offers easy upgradability to emerging standard interfaces,
such as PCMCIA/CardBus and PCI docking stations. Viper-N+ also
features an integrated local bus IDE controller to avoid ISA data bus
bottlenecks.
OPTi coupled its expertise in mobile technology and PCI-based design
to create its second generation 64-bit CPU mobile chipset. The result
is Viper-N+, enabling the highest levels of performance, system
integration and power management capability available for Pentium
PCI-based mobile systems.

**VL82C031/032/033 PS/2 Model 30-compatible chip set c88
***Notes:...
***Info:
The chip set integrates logic on PS/2 Model 30-Compatible systems to
the point of reducing the printed circuit board device count by half
when memories are excluded. Further, while offering complete
compatibility with the PS/2 Model 30-Compatible system, the VLSI chip
set improves system performance by allowing 10 MHz operation with no
"wait states" (using 150 ns DRAMs), supports an additional 8M bytes of
memory using EMS (Expanded Memory Specification) 4.0, and controls
system speed as necessary for optimum performance.
A third device the VL82C037 VGA Video Graphics Controller, is also
used in the PS/2 Model 30-Compatible system and provides high
resolution graphics of up to 800 x 600 pixels with 16 colors. Graphic
capabilities with this resolution are usually found only on more
expensive systems.
The VL82C031 provides the PS/2 Model 30-Compatible system with dual
speed control, 8 MHz or 10 MHz, to operate the system at peak
performance. The device also controls memory, I/O, parity, address
paths, and data paths as well as handling four channels of direct
memory access. The VL82C031 is available from VLSI Technology, Inc. in
an industry-standard plastic 100-pin flatpack.
The CMOS VL82C031 is the System Controller device in the two-chip VLSI
PS/2 Model 30-Compatible chip set.
The chip can be brought to a power-down mode to conserve power
dissipation when static RAM is used. The chip can then be woke up from
power-down mode by an external interrupt.
The VL82C032 provides the PS/2 Model 30-Compatible system with control
of both the keyboard and the pointing device ("mouse"), control of two
serial communi- cation channels, a real-time clock, as well as
controlling both the disk storage and display functions. It also
provides the chip select logic for the functions in controls. The
VL82C032 is available from VLSI Technology, Inc. in an industry-
standard plastic 100-pin flatpack.
The CMOS VL82C032 is the Input/Output Controller device in the
two-chip VLSI PS/2 Model 30-compatible chip set.
[The following text is from the '88 version:]
The VL82C033/OTi-033 is the Floppy Disk Controller and Data Separator
device in the three chip VLSI/OTi PS/2 Model 30-Compatible chip
set. The other two devices are the VL82C031/OTi-031 System Controller
and the VL82C032/OTi-032 I/O Controller.
The VL82C033/OTi-033 provides the PS/2 Model 30-Compatible system with
a uPD 756A- compatible floppy disk controller function, a precision
analog data separator, an internal phase comparator, the required
filters, as well as a voltage controlled oscillator (VCO). The
VL82C033/OTi-033 provides the system with three floppy disk rates:
250K bits-per-second, 300K bits-per-second, and 500K bits-per- second.
the VL82C033/OTi-033 is available form both VLSI Technology, Inc. and
Oak Technology, Inc. in an industry-standard plastic 48 pin DIP.
