Description

Compliant with USB Specification Revision 2.0, the VIA Vectro VT6212L USB2.0 Host Controller delivers consistently high data transfer rates of up to 480Mbps to each of the four downstream USB2.0 ports, supporting multiple connectivity with USB2.0-enabled peripheral devices.

Incorporating two Universal Host Controller Interface (UHCI) cores for full signaling and one Enhanced Host Controller Interface (EHCI) core for high-speed signaling, the VIA Vectro VT6212L is a multi-functional PCI device that utilizes the exceptional bandwidth of USB2.0 to support a wide range of high-speed peripherals, including high resolution video, webcams, digital cameras, next-generation scanners and printers and high-density storage devices.

The VIA Vectro VT6212L root hub consists of four downstream facing ports with integrated physical layer transceiver and legacy support, enabling the simultaneous operation of multiple peripheral devices. The VIA Vectro VT6212L is fully backward compatible with the USB1.1 specification, ensuring seamless connectivity of legacy USB devices.

Based on VIA's low power architecture and advanced 0.22 micron CMOS process technology, the VIA Vectro VT6212L features enhanced power management of I/O power consumption, making it suitable for mobile systems where battery life is critical, and in power sensitive applications.

Supporting the 32-bit PCI-Bus Power Management Interface Specification, the VIA Vectro VT6212L is available as a 4-port PCI USB2.0 add-in card or as a discrete USB2.0 host controller for installation on the mainboard, offering OEMs and system integrators flexibility in designing cost-effective solutions to satisfy the peripheral interface requirements of desktops, mobile systems and other host platforms.

The VIA Vectro VT6212L is available in a 128-Pin LQFP package supporting firmware applications.

Support for the VIA Vectro VT6212L is built into Microsoft Windows XP and Windows 2000. Windows Vista, Win98SE and WinME drivers are also suitable for the VIA Vectro VT6212L.
