nRF8001 Bluetooth® low energy Connectivity IC Active
The nRF8001 is a highly integrated single-chip Bluetooth® low energy Connectivity IC. It integrates a fully compliant Bluetooth v4.0 low energy Radio, Link Layer, and Host stack and features a simple serial interface that supports a wide range of external application microcontrollers. With peak currents as low as 12.5mA and average currents down to 9μA (for a 1s connection interval), the nRF8001 enables battery lifetimes of months to years from a single coin cell. The nRF8001 is a fully qualified Bluetooth v4.0 low energy design and combines the Radio, Link Layer, and Host into a single EPL (End Product Listing) enabling designers to easily create new Bluetooth end products without additional listing fees.
The nRF8001 is specifically designed for Bluetooth low energy applications that operate in the Peripheral (Slave) role. Examples include: proximity tags, PUID watches, remote controls, and sports/fitness/healthcare sensors. The on-chip Link Layer and Host stack also include support for Peripheral GAP role, client, server and security functions.
In addition to best-in-class power consumption, the nRF8001 features an ADC for battery level monitoring, a low tolerance 32kHz RC oscillator that eliminates the need for an external 32kHz crystal, plus a 16MHz crystal oscillator supporting the use of low cost 16MHz crystals. The chip also integrates two voltage regulators, a linear voltage regulator providing a 1.9 to 3.6V supply range, and a DC/DC voltage regulator that when enabled can further cut current consumption by up to 20% when running from a 3V battery cell.
The nRF8001 is available in a 32-pin 5 x 5mm QFN package
nRF8001是高度集成的无线连接解决方案，它使用紧凑的32引脚 QFN封装，尺寸为5x5mm，是完全合格的、完整的蓝牙4.0版本低耗能解决方案，它补充了Nordic半导体现有的ULP nRF24Lxx 和 ANT™ 2.4GHz射频产品线。该器件和最好的超低功耗结合起来，非常适合空间受限制、由钮扣电池供电的应用系统，这些正是低耗能蓝牙技术所针对的用途。这些应用系统包括无线产品和最终用户佩带在身上或携带的传感器，包括移动电话外围设备，例如遥控钥匙和手表，体育健身传感器和保健传感器，以及消费性电子遥控器，家用及工业自动化设备。
此外，nRF8001集成了一个DC/DC稳压器，如果启用，在用钮扣电池供电时，能够进一步把峰值电流和平均电流降低百分之二十。 nRF8001也是第一个完全经过认证的蓝牙 V4.0的低耗能设计，它把射频通信、链路层和主机都纳入一个EPL列表，因而设计人员能够很容易地设计新的蓝牙终端产品，没有任何其他列表费用。
设计人员使用nRF8001芯片，可以把蓝牙低耗能无线连接简单地加到现有的应用系统中，这是由于nRF8001芯片中集成了一个完整的蓝牙 V4.0的低耗能无线电通信技术、链路层和主机栈，支持它作为外设（“从机”）运作，并有一个简单的串行接口支持外部微控制器，设计人员可以按应用系统的具体要求自行选择微控制器。 nRF8001芯片还集成了一个独特的32kHz高精度RC振荡器，不需要使用外部32kHz晶体，并有一个16MHz的晶体振荡器，可以使用低成本16MHz晶体，在片上还有一个线性稳压器，它的电压范围为1.9至3.6V，代替集成在上面的DC/DC稳压器。
