Nordic Semiconductor has provided a preview of ?Blue, its upcoming Bluetooth low energy solution range, designed to bring wireless connectivity to portable devices running on small but standard coin cell (watch) batteries and support battery lifetimes from months to years depending on the application.

?Blue will be a range of single mode Bluetooth low energy solutions based on a single chip architecture integrating radio, baseband and microcontroller with fully embedded Bluetooth low energy software stacks. By providing a complete solution, ?Blue significantly eases the effort and cost for manufacturers to make Bluetooth low energy wireless-enabled products. This high level of integration, tiny chip size and low external component count makes ?Blue suitable for size constrained applications like watches and wearable sensors. ?Blue will also be made available in a number of targeted application variants to suit the specific requirements of products in various market segments.

The Bluetooth solution will provide a true ultralow power (ULP) wireless solution with peak currents low enough to support standard coin cell battery operation and microampere range average current in connected mode enabling months to years of battery lifetime. This can expand the range of applicable application areas where manufacturers can take advantage of Bluetooth wireless connectivity as well as deliver an improved user experience in existing applications. While classic Bluetooth solutions typically require rechargeable batteries and weekly charging cycles, ?Blue will support applications that use non-rechargeable batteries, such as coin cells. Applications that use classic Bluetooth today like Bluetooth enabled watches and remote controls can benefit on both battery lifetime and cost by migrating to ?Blue Bluetooth low energy wireless technology.

In addition, the ultralow power consumption of ?Blue does not come with a compromise on radio performance. ?Blue is built on Nordic's latest class-leading ULP 2.4GHz radio technology. Combined with the robust adaptive frequency hopping of Bluetooth low energy, ?Blue will provide high co-existence performance with other radios like Wi-Fi and classic Bluetooth.

Estimated general availability of the first ?Blue products is late 2009. The first offerings will include the nRF8001, a single mode Bluetooth low energy slave solution designed for watches, mobile phone peripherals, remote controls and sensors.

"We are thrilled to provide this preview of our upcoming Bluetooth low energy solution," says Thomas Embla Bonnerud, product manager for ultra low power wireless at Nordic. "We are also pleased to announce that our single mode solution?Bluewill deliver on the promise of Bluetooth low energy wireless technology: ultra low power consumption that is a fraction of classic Bluetooth radios; coin cell battery operation for between months to years; and last but equally importanthighly integrated single chip solutions that require the minimum of external components."
