VUB300 USB to SD/SDIO
Host Controller Bridge Chip
Low Power, High Speed
VUB300 delivers a unique combination of very high speed data transfer plus the use of original SDIO device manufacturers driver software, greatly simplifying the integration into target systems. Pin for Pin replacement for industry standard SMSC2240 the VUB300 supports all SD/SDIO compliant devices.
VUB300 - LOW POWER, HIGH SPEED
The VUB300 provides a universal SDIO port to hosts that only have USB. It is a USB 2.0 compliant device operating at Hi-Speed (480 Mbps). 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 bus.
Windows/Linux/Mac drivers integrate into the standard operating system SD/SDIO driver stack, allowing use of standard, device manufacturer supplied SDIO drivers and "in-box" supplied SD memory card drivers. Ideal for use in Android devices.
