VT6430 PCI 5-in-1 Flash Card Reader Controller

VT6430Designed for mobile PC and embedded system platforms where low profile is essential, the VT6430 PCI Combo Controller is highly interoperable with a range of flash media, providing card vendors with the utmost flexibility to design versatile, ultra-compact systems that enable customers to read and transfer data from any of seven flash card formats. The chip is a 5-in-1 flash card reader controller that supports SecureDigital (SD), MultiMediaCard (MMC), MemoryStick (MS), MemoryStick Pro (MS Pro), xD PictureCard (XD), SmartMedia (SM), and SDIO host interfaces.

For card reader function the VT6430 PCI Combo Controller provides VIA’s highly compatible combo card reader drivers to the most popular operating systems, that includes Windows® 2000, XP, Server2003, Vista, and  Linux 2.4.x/2.6.x. Furthermore, the Windows drivers of VIA card reader have certificated by Microsoft DTM and got Windows® XP/Vista logo, including x86 and x64 platforms, and includes an enable/disable function allowing specific cards to be switched on or off,  providing the most flexibility for system requirement.
