Wireless USB chipset from Samsung supports data transmission from mobile to tethered CE devices

Samsung has released the S3C2680/ S5M8311 WUSB, an universal serial bus (USB) chipset that supports wireless transmission of data from mobile host devices to a tethered CE devices for viewing. This device is developed using Ultra Wide Band (UWB) technology. This WUSB is offered in a two-chip set. The initial applications of S3C2680/ S5M8311 WUSB are high-resolution cameras, camcorders, TVs and PCs with prospects for adoption in other applications such as tablet PCs, printers, beam projectors, portable HDDs, Blu-ray players, and mobile handsets.

"The ability to handle wireless high-speed data transmission while consuming less power is a key requirement for many consumer electronic devices," said Yiwan Wong, vice president, SOC marketing, System LSI division, Samsung Electronics. "Due to power/performance issues, previous generations of WUSB products were unable to meet the consumers' expectations. Samsung's new WUSB chipset delivers up to 480Mbps (Megabit per second) data transmission rate, at an average power consumption of less than 300mW. This level of power efficiency greatly increases the attractiveness of WUSB connectivity in consumer electronic and mobile applications"

The S3C2680/ S5M8311 WUSB is built using Samsung's 65nm low power logic process technology, this WUSB chipset is a combination of a system-on-chip (SoC) baseband processor and an RF transceiver. This device can be applied in an SD card form factor, in USB dongles, or embedded in consumer and mobile applications. Samsung says that this WUSB chipset allows wireless transmission at a throughput rate of over 200Mbps with power efficiency ten times greater than that of the 802.11g WiFi standard. Samsung also says that the multi-threshold support in this new chipset can decrease power consumption by 30 percent over current WUBS.

This WUSB has an embedded NAND flash memory controller built-in, Samsung's new WUSB chipset is the only product in the market that can support WUSB-enabled SD cards. This type of WSUB-enabled SD card allows pictures and video captured with a digital camera or camcorder to be transmitted wirelessly from the device to a host computer, a TV or a PC monitor for viewing without any wire connections to download the contents from the SD card.

Samsung's WUSB chipset features ARM 9 core, WiMedia v1.2 PHY and various interfaces such as SDIO, SD card, SD host and a NAND flash controller and two high-speed USB 2.0 PHYs. This chipset solution also has a 128-bit AES encryption algorithm for secure data transmission.

Availability: Now in samples volumes in Q4' 2010.
