SiS530/5595 chipset overview

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. 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 providing 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.
