**82C895         System/Power Management Controller (cached)   c:Sep94
***Notes:...
***Info:
Overview
The 82C895 provides a highly integrated solution for fully compatible,
high performance  PC/AT platforms.   This chipset will  support 486SX/
DX/DX2/DX4  and P24T microprocessors  in the  most cost  effective and
power  efficient  designs  available  today.  For  power  users,  this
chipset offers optimum performance for systems running up to 50MHz.

Based  fundamentally  on  OPTi's   proven  82C801  and  82C802  design
architectures,  the 82C895 adds  additional memory  configurations and
extensive  power  management  control  for  the  processor  and  other
motherboard components.

The  820895  supports the  latest  write-back  processor designs  from
Intel, AMD, and Cyrix, as well as supporting the AT bus and VESA local
bus  for   compatibility  and   performance.   It  also   includes  an
82C206-compatible  Integrated Peripherals Controller  (IPC). all  in a
single 208-pin PQFP (Plastic Quad Flat Pack) package for low cost.

2.1 Power Management

This block diagram [see  datasheet] exemplifies the flexibility of the
82C895/82C602 GREEN  strategy.  System designs  can easily accommodate
both SLe  and non-SLe  CPUs. If  an Intel non-SLe  CPU is  used, SMI#,
SMIACT#, and  FLUSH# are no  connects.  One design can  easily accomm-
odate both types of processors with minimal changes for upgrades.

**5591/5592/5595 (David)   Pentium PCI A.G.P. Chipset        <01/09/98
***Info:
The SiS5591/5592  SiS5595 glueless P5  A.G.P. chipset provides  a high
performance/cost index  Desktop/Mobile solution for  the Intel Pentium
P54C/P55C, AMD K5/K6, and Cyrix M1/M2 A.G.P. system.

The SiS5591/SiS5592  A.G.P./PCI controller integrated  the Host-to-PCI
bridge, the L2 cache  controller, the DRAM controller, the Accelerated
Graphics  Port interface,  and the  PCI IDE  controller. The  L2 cache
controller can  support up to 1  M P.B. SRAM, and  the DRAM controller
can  support EDO/FP/SDRAM memory  up to  768 MB  with optional  ECC or
parity check  function. The  A.G.P. 1.0 compliance  interface supports
both  1X, and  2X speed  mode with  sideband address  capability.  The
built-in fast  PCI IDE  controller supports the  ATA PIO/DMA,  and the
Ultra DMA/33 functionality.

SiS5591  and SiS5592  have some  pin-out switching  to  facilitate the
main-board layout.  SiS5591 pin  assignment is based  on the  ATX form
factor,  and  SiS5592  pin  assignment   is  based  on  the  NLX  form
factor. Beside  the pin-out switching, SiS5591 and  SiS5592 is totally
the same on the internal logic circuit.

The SiS5595 PCI  system I/O integrates the PCI-to-ISA  bridge with the
DDMA,  and  Serial  IRQ  capability,  the ACPI/Legacy  PMU,  the  Data
Acquisition  Interface, the Universal  Serial Bus  host/hub interface,
and the ISA  bus interface which contains the  ISA bus controller, the
DMA controllers,  the interrupt controllers,  and the Timers.  It also
integrates the Keyboard controller, and the Real Time Clock (RTC). The
built-in USB controller,  which is fully compliant to  OHCI (Open Host
Controller  Interface),  provides two  USB  ports  capable of  running
full/low speed USB devices.  The Data Acquisition Interface offers the
ability of monitoring and reporting the environmental condition of the
PC. It could  monitor 4 positive analogue voltage  inputs, 2 Fan speed
inputs, and one temperature input.
