Available in a 5 x 5-mm QFN package, the µBlue nRF8001 Bluetooth solution delivers sub-12.5-mA peak currents and connected mode average currents as low as sub 12 µA promising years of battery life from a coin cell battery source. The part is suited for wireless products and sensors designed to be worn on or carried close to the end-user’s body including mobile phone peripherals such as proximity tags and watches, sports and fitness, and health sensors, as well as consumer electronic remote controls, and home and industrial automation devices. It integrates a dc/dc regulator that, if enabled, can further cut peak current and average currents by up to 20% when running from a coin-cell battery source.
It is the first fully qualified Bluetooth v4.0 low-energy design to combine the Radio, Link Layer, and Host into one End Product Listing, enabling designers to easily create new Bluetooth and products without any additional listings. The nRF8001 chip also integrates a unique low-tolerance 32-kHz RC oscillator that eliminates the need for external 32-kHz crystals, a 16-MHz crystal oscillator supporting low-cost 16-MHz crystals, plus an on-chip linear voltage regulator that provides a supply range of 1.9 to 3.6 V as an alternative to its integrated dc/dc regulator.
