Samsung's New Wireless USB Chipset Supports High-Speed, Low-Power Data Transmission Between Mobile and CE Devices


Samsung today introduced its latest wireless universal serial bus (USB) solution, developed using Ultra Wide Band (UWB) technology.

Offered in a two-chip set, Samsung's newest S3C2680/ S5M8311 WUSB solution enables high definition content to be wirelessly transmitted from a mobile host device to a tethered device for viewing. Initial applications are high-resolution cameras, camcorders, TVs and PCs with prospects for adoption in other applications including 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, System LSI marketing, 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"

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

With 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.

Leveraging an ARM 9 core, Samsung?s WUSB chipset features WiMedia v1.2 PHY and also has various interfaces such as SDIO, SD card, SD host, as well as 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.

Samsung?s S3C2680/S5M8311 WUSB chipset is now sampling to select customers, and it is slated for mass production in the fourth quarter of 2010.
