**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.

***Info:
GENERAL DESCRIPTION
This data sheet covers two products: W83977F/G, and W83977AF/AG whose
pin assignment, and most of the functions are the same. W83977AF/AG is
an advanced version of W83977F/G featuring the FIR function.
W83977F/G, W83977AF/AG are evolving products from Winbond’s most
popular I/O chip W83877F -- which integrates the disk drive adapter,
serial port (UART), IrDA 1.0 SIR, parallel port, configurable
plug-and-play registers in one chip --- plus additional powerful
features: ACPI, 8042 keyboard controller with PS/2 mouse support, Real
Time Clock, 14 general purpose I/O ports, full 16-bit address
decoding, TV remote IR (Consumer IR, supporting NEC, RC-5, extended
RC-5, and RECS-80 protocols). In addition, W83977AF/AG provides the
functions of IrDA 1.1 (MIR for 1.152M bps or FIR for 4M bps).
The disk drive adapter functions of W83977F/G, W83977AF/AG include a
floppy disk drive controller compatible with the industry standard
82077/ 765, data separator, write pre-compensation circuit, decode
logic, data rate selection, clock generator, drive interface control
logic, and interrupt/ DMA logic. The wide range of functions
integrated onto the W83977F/G, W83977AF/AG greatly reduces the number
of components required for interfacing with floppy disk drives. The
W83977F/G, W83977AF/AG supports up to four 360K, 720K, 1.2M, 1.44M, or
2.88M disk drives and data transfer rates of 250 Kb/s, 300 Kb/s, 500
Kb/s,1 Mb/s, and 2 Mb/s.
The W83977F/G, W83977AF/AG provide two high-speed serial communication
ports (UARTs), one of which supports serial Infrared communication.
Each UART includes a 16-byte send/receive FIFO, a programmable baud
rate generator, complete modem control capability, and a processor
interrupt system. Both UARTs provide legacy speed with baud rate
115.2k and provide advanced speed with baud rate 230k, 460k, and 921k
bps which support higher speed modems. W83977AF/AG alone provides
independent 3rd UART (32-byte FIFO) dedicated for IR function.
The W83977F/G, W83977AF/AG supports one PC-compatible printer port
(SPP), Bi-directional Printer port (BPP) and also Enhanced Parallel
Port (EPP) and Extended Capabilities Port (ECP). Through the printer
port interface pins, also available are: Extension FDD Mode and
Extension 2FDD Mode allowing one or two external floppy disk drives to
be connected.
The configuration registers support mode selection, function
enable/disable, and power down function selection. Furthermore, the
configurable PnP features are compatible with the plug-and-play
feature demand of Windows 95TM, which makes system resource allocation
more efficient than ever.
W83977F/G, W83977AF/AG provides functions that comply with ACPI
(Advanced Configuration and Power Interface), which includes support
of legacy and ACPI power management through SMI or SCI function
pins. W83977F/G, W83977AF/AG also has auto power management to reduce
power consumption.
The keyboard controller is based on 8042 compatible instruction set
with a 2K Byte programmable ROM and a 256-Byte RAM bank. Keyboard BIOS
firmware is available with optional AMIKEY-2, Phoenix MultiKey/42, or
customer code.
The W83977F/G, W83977AF/AG provides a set of flexible I/O control
functions to the system designer through a set of General Purpose I/O
ports. These GPIO ports may serve as simple I/O or may be individually
configured to provide a pre-defined alternate function.
W83977F/G, W83977AF/AG is made to fully comply with Microsoft PC97
Hardware Design Guide. IRQs, DMAs, and I/O space resource are flexible
to adjust to meet ISA PnP requirement. Full 16-bit address decoding is
also provided. Moreover W83977F/G, W83977AF/AG is made to meet the
specification of PC97‘s requirement in the power management: ACPI and
DPM (Device Power Management).
