Benefits of the VIA Vectro VT6210L

Multi-functionality
The two downstream ports and full legacy support enable the running of multiple high-speed peripherals simultaneously.

Hi-Speed USB2.0 Performance
Certified by the USB Implementers Forum for Hi-Speed USB2.0 operation, the VIA Vectro VT6210L is one of the top performers in the industry, delivering superior performance, especially in data access and read/write speeds.

Simplicity
A cost-effective single chip peripheral connection interface for USB2.0-enabled PC peripherals as well as the new generation of higher bandwidth devices such as digital cameras and MP3 players.

Energy-Efficiency
Advanced power management features exert control over I/O power consumption, ensuring the benefits of the VIA Vectro VT6210L even in low power applications.

Flexibility
Available as an add-in card or a chipset installed directly onto the mainboard, the VIA Vectro VT6210L provides the most flexible approach to system builders and OEMs to add USB2.0 to their product line-up.

Description

The VT6210L USB 2.0 UHCI and EHCI Host Controller for the PCI 2.2 Bus provides higher bandwidth (480 Mbps) and is backward compatible with USB 1.1. It implements Universal Serial Bus Specification Revision 2.0 and is compliant with UHCI 1.1 and EHCI 1.0 with a 32-bit PCI host bus interface. The VT6210L adopts 2 DMA engines with pipelined control for USB data transfer bandwidth improvement and dynamic clock stop control for power consumption reduction.

The VT6210L supports 2 downstream facing ports with 1.5 (low-speed), 12 (full-speed) and 480 (high-speed) Mbps transaction capability. The Root Hub is integrated with physical-layer transceivers shared by UHCI (for full/low-speed) and EHCI (for high-speed) Host Controllers. The VT6210L also supports PCI-Bus Power Management Interface Specification 1.1 and has legacy support for all downstream facing ports.

The VT6210L is ready to provide a PCI 2-port USB2.0 peripheral-interface to satisfy the needs of desktops, mobile systems, and other host platforms. Support for the VT6210L is built into Microsoft Windows XP and Windows 2000. Windows Vista, Win98SE and WinME drivers are provided by VIA.
