One key advantage of Bluetooth
Low Energy (LE) is the long battery life it gives portable devices that are always-on, but still light-weight and miniature in form-factor. QN908x is a BLE SOC bringing that advantage into your design.
QN908x provides two packages, both are very small:
- 6 x 6 mm HVQFN48
- 3.2 x 3.2 mm WLCSP
From power consumption perspective below are illustrations captured from Keysight N6705B Power Analyzer In both illustrations BLE is under connection status but with different interval setting
Here is a summary of power consumption in various connection cases.
It is very easy to run the test for above cases as QN908x provides a project named power_profiling in SDK.
For more inforamtion about test setup and power consumption under other test conditions, please visite QN9080 product web page and download the specific application note as below.
