Description

Certified by the USB Implementers Forum for Hi-Speed Low Power USB 2.0 operation, the VIA Vectro VT6204 is the first USB 2.0 to IDE bridge controller to be granted this globally recognized certification. Featuring full speed and high speed transfer rates, ultra-low power consumption and high interoperability with all kinds of IDE devices and built-in SRAM memory buffer, the VIA Vectro VT6204 provides the most favorable solution for direct and instantaneous point-to-point connection, enabling free and effective communication between IDE-based consumer electronics and handheld devices with PCs and mobile systems.

The VIA Vectro VT6204 transfers data at speeds of up to 480Mbps, while maintaining very low operating power consumption of less than 100mA and configuration power of only 60mA. Through its low power architecture and advanced CMOS 0.22µm process technology, VIA has minimized the power consumption of the VIA Vectro VT6204 by more than 80% of the maximum allowable power for USB peripherals operating without the use of external power.
The VIA Vectro V6204 is thus ideal for use in consumer peripherals and mobile systems, saving battery life of notebooks and other battery dependable peripheral devices.

Compliant with USB Specification Revision 2.0, ATA/ATAPI Specification Revision 6.0 and interface compliant with the UTMI (USB 2.0 Transceiver Macrocell Interface) Specification, the VIA Vectro VT6204 utilizes the exceptional bandwidth of USB 2.0 to support a wide range of 3.5 inch and 2.5 inch high density HDD, CDROM, DVDROM, CD-RW, DVD-RW and any other USB IDE-based networking and communication device.

The VIA Vectro VT6204 allows for dynamic attach and re-attach to the USB bus to allow hot-swap of devices. The External Serial (EEPROM) Interface enables memory retention and supports serial number, vendor number, product ID and miscellaneous storage.

Support for the VIA Vectro VT6204 is built into Microsoft® Windows® XP and Windows® 2000. Win98SE and WinME drivers are also suitable for the VIA Vectro VT6204.
