pt890_mainThe VIA PT890 features a high bandwidth V-Link bus to allow communication between the chipset’s North and South bridges at 533MB/sec. When combined with solutions such as the market-leading VIA VT8237A South Bridge and a broad array of VIA companion chips, the VIA PT890 provides a comprehensive range of storage, multimedia and connectivity features, including native Serial ATA and V-RAID, 6-channel or 8-channel VIA Vinyl Audio, VIA Velocity™ Gigabit Ethernet, USB 2.0, and 1394.

Benefits of VIA PT890

VIA StepUp Memory Support: The VIA PT890 integrates VIA’s StepUp memory technology for lightning fast access to system memory and optimum system performance. VIA’s StepUp memory technology enables support for DDR1 and DDR2 memory standards giving maximum flexibility.

Native Serial ATA/RAID Support: The VIA VT8237A South Bridge features a native Serial ATA/RAID controller, providing direct support for two 150MB/s Serial ATA devices, and an additional two (for a total of four SATA devices) in combination with the SATAlite™ interface. The integrated V-RAID controller supports native RAID 0, RAID 1, RAID 0+1* and JBOD, ensuring optimum data integrity and system performance, while the user-friendly V-RAID software interface enables easy disk array configuration and management.

VIA Vinyl Multichannel Audio Suite: Delivering rich, warm surround sound at resolutions as high as 24/96 through up to six- or eight- channel outputs, the VIA Vinyl audio suite includes support for VIA Vinyl HD audio, VIA Vinyl AC’97 audio, and VIA Vinyl Gold Audio, representing the highest levels of audio quality in a mainstream integrated or onboard solution.

VIA Modular Architecture Platform: The VIA PT890 chipset is part of VIA’s unique Modular Architecture Platform (V-MAP), which minimizes design times and time-to-market for motherboard partners through a flexible, pin-compatible design approach for VIA core-logic solutions. Motherboard partners are able to cover multiple market segments with fewer design resources, and also benefit from a single unified driver base.

Unified VIA Hyperion Pro Drivers: VIA’s unified approach to drivers has been established for eight generations of chipsets, allowing end users to benefit from seamless hardware and software compatibility.

* RAID Level 0+1 requires four Serial ATA drives; support for the two additional drives can only be implemented with two external Serial ATA ports enabled through a SATALite PHY.
