No. Parameter Condition Minimum Typical Maximum Unit
7.3.4 Supply current MCU @ 16MHz (int. RC 32MHz),
transceiver in state RX_ON
28 mA
7.3.5 Supply current MCU @ 16MHz (int. RC 32MHz),
transceiver in state BUSY_TX
26 mA
For current consumption measurements, please regard the Z-diode mounted on the
REB. It prevents applying overvoltage stress to the radio transceiver circuit as well as
protection against reverse polarity.
Figure 7-1. REB overvoltage protection mechanism.
The Z-diode draws approximately 6mA at 3.0V (type: BZG05-C3V9), which should be
considered in overall current consumption. The Z-diode shall be removed for low-
power designs or in case of current measurements.
