nRF8001 Bluetooth

Nordic Semiconductor ASA is already shipping silicon samples and development kits of the nRF8001, the first member of its ?Blue Bluetooth low-energy single-mode solution.

While the Bluetooth low-energy specification is still under development, Nordic is providing a complete beta implementation, including host and profiles subsystem, enabling its lead customers to begin both hardware and software development of their first single-mode Bluetooth low-energy applications. Nordic expects to have a feature complete and qualified product shortly after the specification is finalized by the Bluetooth SIG.

The ?Blue nRF8001 is a highly-integrated single-mode slave solution in a 32-pin 5mm x 5mm QFN package. It features a fully embedded radio, link controller, and host subsystem. Its profiles and application examples are included within the ?Blue SDK. It uses less that 15mA peak current consumption while its average current consumption is in the microampere range. It is expected to enable years of battery operating life for coin cell battery-powered applications (depending on duty cycle).

Nordic's ?Blue family 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 will significantly ease 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 ideal 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.
