SiS Announces Industrys First and Only 100MHz

Socket 7 Chipset with Integrated 3D Graphics - SiS530

Silicon Integrated Systems Corp. (SiS), a leading core
logic supplier, announces the industry's first and only 100MHz socket 7 chipset
with integrated 3D VGA, the SiS530. This announcement follows SiS' own earlier
success in SiS5598, the industry's only single-chip core logic solution with integrated
2D graphics which has exceeded 5 million units in shipment and set the trend for future

The product announced today, the third-generation core logic solution with integrated graphics from SiS, represents the latest innovation by the company. The SiS530 supports 100MHz CPU host bus, and incorporates the full function of SiS' own popular 3D solution, SiS6326AGP, to allow 3D acceleration at 100MHz speed on a 64bit internal host bus. With this architecture, the video data transfer rate achieves 800MB/sec, far superior to the conventional 32bit bus at 66MHz.

With this announcement, SiS delivers again on its commitment to provide leading edge technology for the benefit of the masses. As 3D graphics capability becomes a necessity for future applications, the advent of SiS530 will undoubtedly bring the best value in performance and affordability to the end users.

The SiS530 consists of the following key features:

(i) MS PC99 and PCI 2.2 compliant.
(ii) Dual 2.5v/3.3v CPU interface, supports 66/75/83/95/100MHz synchronous and
asynchronous host bus frequencies.
(iii) PC100 DRAM controller, supports 3 DIMMs and up to 1 gigabyte memory.
(iv) Advanced 2D/3D graphics/video accelerator, with peak polygon rate of 800K/sec.
(v) Ultra DMA-66 IDE controller.
(vi) 2MB synchronous cache controller.
(vii) Supports digital flat panel, TFT-12/18/24bit.

The SiS530 also has a companion chip in SiS5595, the PCI system controller. It includes the PCI to ISA bridge, DDMA support, SIRQ, ACPI/Legacy PMU, environmental controller, and USB. The SiS530 is housed in a high pin count BGA package, while SiS5595 is in 208 pin PQFP.

The product will be sampled in August, with production planned by September. The chipset is priced at $29 for 10K orders.

Silicon Integrated Systems Corporation (SiS) is the only publicly listed fabless semiconductor company in Taiwan Stock Exchange. It was founded in 1987 and is located in Science-based Industrial Park in Hsin-Chu, Taiwan. The company focuses on leading-edge logic products for the mainstream PC market, including core logic, multimedia, and datacom.
