Description

Certified by the USB Implementers Forum for Hi-Speed Low Power USB 2.0 operation, the VIA Vectro VT6205 is the first USB 2.0 to 9-in-1 flash card reader controller to be granted this globally recognized certification.

The VIA Vectro VT6205 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 VT6205 by more than 80% of the maximum allowable power for USB peripherals, making it the ideal solution for flash card readers to be used with PCs and mobile systems, ensuring reliability in power sensitive applications and saving battery life of notebooks.

Compliant with USB Specification Revision 2.0 and with the UTMI (USB 2.0 Transceiver Macrocell Interface) Specification, the VIA Vectro VT6205 utilizes the exceptional bandwidth of USB 2.0 to support a wide range of flash media use with digital devices such as digital cameras, MP3 players and PDA’s.

The VIA Vectro VT6205 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.

The VIA Vectro VT6205 is widely supported by most of the existing operating systems, including Microsoft® Windows® XP, Windows® 2000, Windows® ME, Windows® 98, Windows® 98SE, Mac OS 9.x, Mac OS X, and the Linux kernel 2.4.0 and future versions.
