Bluetooth SoC enables easy smart tag designs
The µBlue nRF8002 Bluetooth SoC is an easy-to-design-in single chip solution for Bluetooth Smart (as Bluetooth low energy will now be marketed to consumers) wireless tags and other accessories such as bracelets, pendants, keychains, small toys, and armbands. Housed in a compact 5 x 5-mm QFN package, the part includes a fully qualified Bluetooth v4.0 low energy protocol stack, a highly configurable application layer, and built-in support for a range of Bluetooth v4.0 profiles including: Find Me, Proximity, Alert Notifications, and Battery Status.
Features include a low-power operation without the need for an external 32-kHz crystal, peak currents as low as 13 mA, an on-chip battery monitor, and months to years of battery lifetime from a single coin cell battery (depending on duty cycle). Also available is the nRFgo-compatible nRF8002 development kit, where developers can design Bluetooth Smart tags and accessories using a simple graphical user interface that allows them to go no deeper than configuring the built-in application layer and mapping inputs and outputs to external components such as buttons, LEDs, and buzzers. The development kit even includes a small coin cell-powered tag design example that can be used for development, prototyping, and testing. (Nordic nRFgo dev kit, $99 — samples available now.)
