C-bus is only functional for voltages between 3.0 V and 3.6 V.
The power consumptions are very dependent on the software settings and can vary a lot.
CMOS leakage current. All blocks are disabled except the bias currents of the band gap reference and the power-on reset circuit.

All measurements performed on sampling basis with HCI firmware loaded in the PCF87852 internal
ROM.
Measurements are done with the 13 MHz oscillator in slave mode.
Measurements are done with a 32.768 kHz crystal connected to generate the Bluetooth low power
clock.
Measurements are done with a 13 MHz crystal connected and the Bluetooth low power clock derived
from the 13 MHz.
