nRF8001 Product Specification
Revision 1.2
13.3 Current consumption calculation examples
You can calculate the average current consumption using the nRFgo Studio Current Consumption
Calculator. For more information on nRFgo Studio, visit www.nordicsemi.com
.
A set of typical profile scenario examples are presented below for different use cases based on typical
profile scenarios. The current consumption values are calculated by the nRFgo Studio Current
Consumption Calculator.
13.3.1 Estimated lifetime for proximity profile
The proximity profile typically has the following connection parameters:
• A 100% connection model, that is, the proximity tag is nearly always connected.
• 1 second connection interval.
• Zero data for 99% of the time, data is only sent if a condition is met, 4 bytes.
• Peripheral device is a server and initiates alerts upon receiving write commands.
• Pipe used: RX pipe.
• No encryption used.
• Total system sleep clock accuracy ± 300 ppm.
• 220 mAh coin cell battery.
