KEY FEATURES • Bluetooth Specification v4.0 compliant single mode low energy solution • Complete PHY, Link Controller and Host subsystem • Profiles and example applications provided in µBlue SDK • Cost and power optimized for slave operation • Simple SPI based Application Controller Interface (ACI) • Full Link Controller and Host security • 1.9 to 3.6V operation • Linear voltage regulator • Step-down DC/DC voltage regulator providing up to 20% peak current reduction • Sub 14mA peak current with linear voltage regulator • Supports sub 10µA average current operation • 16MHz crystal oscillators • Supports low cost external 16MHz crystals • Ultra low power 32kHz crystal and RC oscillators • Support operation without external 32kHz crystal • Battery voltage monitor • Temperature sensor • RoHS compliant 5x5mm 32-pin QFN package APPLICATIONS • Sports and fitness sensors • Healthcare and medical sensors • Continua™ Version Two certified products • Remote controls • Watches • Mobile phone peripherals • Automation sensors • Proximity tags Complete Bluetooth low energy solution The nRF8001 connectivity-on-chip solution The nRF8001 is the first member of Nordic Semiconductor`s µBlue family of Bluetooth low energy solutions. It is designed to be used in conjunc- tion with an external microcontroller running the application. The nRF8001 integrates a complete PHY, Link Controller and Host single mode Bluetooth low energy subsystem and features a simple SPI based interface to the application microcontroller. Qualified profiles, APIs and example application are provided as part of the µBlue SDK which is easily portable to a range of different application microcontrollers. This system segmentation allows the nRF8001 to be used with the best-fit microcontroller for a specific applica- tion as well as ease integration and end product qualification as application and protocol stack does not share the same microcontroller. nRF8001 application block diagram Optimized single mode slave solution Bluetooth low energy features The nRF8001 is a cost and power optimized solution for single mode slave applications such as sports, healthcare and automation sensors, watches, remote controls, proximity tags and mobile phone peripherals. The on-chip protocol stack provides a full slave role support, encryption, client and server protocols, just works security, all mandatory client and server profile features as well as direct test mode for PHY qualification. nRF8001 protocol stack Designed for coin cell battery operation Sub 14mA peak, micro ampere range average currents The nRF8001 has been designed from scratch to meet the stringent peak current requirements of standard coin cell batteries like CR2032 where total peak current is advised to be below 20mA at any time. Using the on-chip linear regulator the nRF8001 has a peak current below 14mA, thus provid- ing a valuable headroom for the application microcontroller. Depending on the application and profile nRF8001 can support average currents below 10µA, enabling years of battery lifetime on standard coin cell batteries.
