The VUB300 USB to SDIO bridge converts USB interfaces to SDIO host interfaces. The SDIO host function conforms to the SDIO Host specification with a generic USB wrapped interface to extend SDIO host controller support to the USB. The SDIO interface supports one- or four-bit SDIO and SD interrupt with automatic card detection. The chip also handles bus-powered designs requiring less than 450 mW from a 3.3V supply. In a 6 mm x 6 mm QFN, price is $5.30 each/10,000. SAELIG CO., Pittsford, NY. (888) 772-3544.
