Saelig Introduces USB-to-SDIO Host IC

By DE Editors

Saelig Company, Inc. has introduced the VUB300 a 6-x-6mm QFN IC that converts a USB interface to an SDIO Host Interface. VUB300 is a single-chip USB to SDIO bridge that allows SDIO and SD compliant devices to be connected to any host PC via USB.

The VUB300 provides a universal SDIO port to hosts that only have USB capabilities. 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.

Its universal support for any SDIO device allows it to run with any manufacturer’s existing driver and application software without the need for any modification, according to the company. Drivers integrate into the standard operating system SD/SDIO driver stack. With a USB2.0 Hi-Speed connection, transfers of up to 480 Mbps are possible, says Saelig, but VUB300 is also backward-compatible with Full-Speed USB2.0 and USB1.1.

VUB300’s SDIO interface supports 1bit or 4bit SDIO and SD Interrupt with automatic card detection.
