Product overview

nRF8001’s main physical features are the Bluetooth low energy PHY and the Bluetooth low energy stack

that handles the link controller and host stack. It also includes additional analog sub-systems needed for

the Bluetooth low energy operation, such as power management and several oscillator options.

nRF8001 has on-chip non-volatile memory for storing service configurations. This on-chip storage lets you

select and combine the necessary services for your application, reducing the requirements on your

application controller for handling all real-time operations related to the Bluetooth low energy

communication protocol.

nRF8001 includes a power supply voltage monitor and a temperature sensor that further reduces the

requirements to the application controller. These features are accessible through the Application Controller

Interface (ACI).

nRF8001 also offers an optional output signal (ACTIVE) that is activated before the radio becomes active.

This timing signal enables you to control the peak current drain of your application, avoiding overload of

your power supply (for most applications this is usually a small battery). You can also use this timing signal

to control the application circuitry, avoiding noise interference when the nRF8001 radio is operating.

A separate serial interface (UART) gives you access to the Bluetooth low energy Direct Test Mode (DTM).

This interface is used to control the Bluetooth low energy radio (RF PHY) and is supported by

commercially available Bluetooth test equipment used for Bluetooth qualification. This serial interface also

enables you to test radio performance and to optimize your antenna.
