Staccato launches industry’s first 65nm CMOS single-chip device for UWB

From its inception, Staccato Communications has targeted single-chip UWB solutions. With its latest product release, the company is unleashing the Ripcord2, its first 65nm UWB device that supports multiple protocols, including wireless USB, high-speed Bluetooth, wireless IP and wireless audio/video. In addition, several features were added to Ripcord2, including support for WiMedia Band Groups 1, 3 and 6, as well as the capability for detection and avoidance (DAA).

“With the Ripcord2, we believe we have built in all the features required by mass deployment in the markets of interest to us, including lower power, lower cost, smaller size, and higher performance, providing a worldwide compatible solution in a single device,” explained Jeff Chang, vice president of marketing.

Housed in a 5x5mm package, the Ripcord2 device is sampling now, with production expected in 1Q next year. Its key features include:

Ripcord2 Features:

  • Single-chip 65nm all-CMOS implementation
  • Integrated RF front-end, digital baseband, MAC and IO
  • Support for WiMedia Band Groups 1, 3 and 6
  • Support for all Time Frequency Codes (TFC 1-10) and data rate modes (53.3-480Mbps)
  • Support for detection and avoidance (DAA)
  • Protocol Independent Kernel (PIK) architecture supports multiple protocols
  • USB 2.0 host/device and SDIO 2.0 interfaces

The Staccato design team has been working on this chip for the better part of two years, and decided to skip 90nm and go right to 65nm. What was the most difficult part of this decision? “When you are working with a newer process, the computer models tend to be less accurate,” said Chang, “We had to design this very complex radio with models that weren't mature. That made it challenging.”

In terms of the competition, Marty Colombatto, Staccato's CEO sees the new chip this way, “Our competitors broke up the problem a different way (a two-chip approach). But with a two-chip implementation, you don't get to the best cost, size, and power. We took the more challenging path (a single-chip solution), but one that we thought would get us to mass deployment.”

In terms of off-chip components, the Ripcord2 requires a bandpass filter and antenna. For more information, click here here. Samples and development kits are available now.
