**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.

**530/5595 (Sinbad) Host, PCI, 3D Graphics & Mem. Ctrl.<11/10/98
***Info:
The P5 A.G.P./VGA chipset, SiS530/5595, provides a high performance/
cost index Desktop/Mobile solution for the Intel Pentium P54C/P55C,
AMD K5/K6/K6-II, Cyrix M1/M2 and other compatible Pentium CPU with 3D
A.G.P. VGA system.
The Host, PCI, 3D A.G.P. Video/Graphics & Memory Controller, SiS530
integrates the Host- to-PCI bridge, the PCI interface, the L2 cache
controller, the DRAM controller, the high performance hardware 2D/3D
VGA controller, and the PCI IDE controller.
The Host interface supports Synchronous/Asynchronous Host/DRAM
clocking configuration to eminently improve the system performance and
DRAM compatibility issues.
The L2 cache controller can support up to 2 MB P.B. SRAM, and the DRAM
controller can support SDRAM memory up to 1.5 GBytes with three
double-sided SDRAM DIMMs configuration. The cacheable DRAM sizes
support up to 256 MBytes.
The built-in fast PCI IDE controller supports the ATA PIO/DMA, and the
Ultra DMA33/66 function that support the data transfer rate up to 66
MB/s. It provides the separate data path for two IDE channels that can
eminently improve the performance under the multi-tasking environment.
The A.G.P. internal interface is supported for integrated H/W 3D VGA
controller. The integrated VGA controller is a high performance and
targeted at 3D graphics application. In addition, the integrated 3D
Video/Graphics controller adopts the 64bits 100MHz host bus interface
high technology to improve the performance eminently. To cost-
effective the PC system, the share system memory architecture will be
adopted and it can flexibly using the 2MB, 4MB and 8MB frame buffer
size from programming the system BIOS. [something got confused in
translation there didn't it?] To enhance the system performance,
SiS530 also supports the local frame buffer solution and memory sizes
can support up to 8MB with SDRAM and SGRAM.
In addition to provide the standard interface for CRT monitors, it
also provides the Digital Flat Panel Port (DFP) for a standard
interface between a personal computer and a digital flat panel
monitor. This port allows a host computer to connect directly to an
external flat panel monitor without the need for analog-to-digital
conversion found in most flat panel monitors today. As for DVD
solution, the integrated 3D VGA controller also support DVD H/W
accelerator to improve the DVD playback performance.
The SiS5595 PCI system I/O integrates the PCI-to-ISA bridge with the
DDMA, PC/PCI DMA 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, the Timers
and the Real Time Clock (RTC). It also integrates the Keyboard
Controller and PS/2 mouse interface that can support keyboard power on
function for users to power on system by entering the hot key or
password from keyboard. 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 5 positive
analog voltage inputs, 2 Fan speed inputs, and one temperature input.
In addition, SiS5595 also supports ACPI function to meet Advanced
Configuration and Power Interface (ACPI) 1.0 specification for Windows
98 environment, it can support power-management timer, Power button,
Real-time clock alarm wake up, more sleeping state, ACPI LED for
sleeping and working state, LAN wake up, Modem Ring In wake up, and
OnNow initiative function.
