VUB300 USB-SDIO Host Controller Interface Chip
Extending the capabilities of SD and SDIO devices into the world of USB, and also allowing expansion of Laptop and Desktop PC's into the world of SD and SDIO devices, the VUB300 is a USB to SDIO host controller bridge chip interface that allows SDIO and SD compliant devices to be connected to any host PC via the Universal Serial Bus (USB). 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.
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.
For embedded and external applications
The VUB300 has been designed as a QFN 36-pin 6x6mm package for applications that require a very high speed interface, including:
- PC Motherboards
- Universal SD card readers
- Embedded systems
- UMPC
- Custom systems
- 802.11n Wi-Fi, WiMAX, CDMA, GPRS, UMTS etc. modems
- GPS, Bluetooth modules
Device Support
The VUB300 conforms to:
- SD Specifications Part 1 Physical Layer Specification Version 2.00
- SD Specifications Part E1
- SDIO Specification Version 2.00.
The VUB300 supports any SD or SDIO device that conforms to the SD/SDIO specifications.
Host Support
The VUB300 conforms to the USB 2.0 Specification.
Operating System Support
The VUB300 SDIO host controller drivers are supported on the following operating systems:
- Linux
- Windows 2000 / Windows XP
- Windows Vista 32 / Windows Vista 64
- Windows 7
- Windows Mobile/PocketPC/CE
- Apple MAC OSX
The drivers integrate with the generic SDIO host stack providing seamless functionality with existing SD and SDIO device drivers.
Functionality and Design
