The RTU7105 integrates Protocol Adaptation Layers, a Media Access Controller (MAC), a baseband processor, RF transceivers, and USB 2.0 and SDIO interfaces.

The RTU7105 is suitable for all Wireless USB device applications, including mobile and portable systems. According to Realtek, the RTU7105 offers sharply lower cost, space and power consumption compared with conventional multi-chip products. The RTU7105 provides a full array of Certified Wireless USB device functions, including all transfer types (control, bulk, interrupt, and isochronous), cable and numeric association models, plus a multi-host capability to maintain connection-contexts with up to 16 wireless hosts.

With USB 2.0 and SDIO 1.2 interfaces, the RTU7105 can function as a device wire adapter, or as a native Wireless USB device, offering significantly higher system throughput. In addition, the RTU7105's CrossBridge technology provides an easy migration path to Certified Wireless USB by extending the wired USB 2.0 functionality to both wired and wireless USB.

The MAC is based on WiMedia MAC 1.0 and includes self- beaconing support for Certified Wireless USB. WiMedia MAC 1.0 support enables multi-protocol functionality.

The RTU7105 supports the most recent version of the WiMedia LLC Protocol (formerly known as WiNet), a protocol that enables IP-over-UWB, offering a flexible, peer-to-peer, high-throughput mode.

The RTU7105 integrated radio provides dual-band capabilities, with support for both WiMedia Band Group 1 (3.168~4.752 GHz) and Band Group 3 (6.336~7.920 GHz). The RTU7105 complies with the latest WiMedia PHY 1.1 specification, supporting data rates of 53.3-Mbits/s to 480-Mbits/s within Band Groups 1 and 3, and also implements all mandatory portions of the forthcoming WiMedia PHY 1.2 specification, including three new frequency hopping modes in each Band Group for additional spectrum flexibility.

The RTU7105 comes in an ultra-compact 9mm x 9mm Quad Flat No-Lead (QFN) plastic package, and will also be made available in a smaller Chip Scale Package (CSP) form.

The RTU7105 will be demonstrated at the Realtek booth, located in South Lounge (T3F1) at Computex, Taipei, from June 5-9.
