TABLE 2-3: CURRENT CONSUMPTION
Parameter Min. Typ. Max. Units
Supply Current
TX mode Peak Current at VDD = 3V, TX = 0 dBm, Buck mode — 10 at +25°C 13 at +75°C/+85°C mA
RX mode Peak Current at VDD = 3V, Buck mode — 10 at +25°C 13 at +75°C/+85°C mA
Low-Power Mode Current
(2)
— 60 at +25°C — µA
Shutdown Low-Power Mode 1 — 2.9 µA
Note 1: The current measurements are characterized across a sample of the RN4870/71 module at room tem-
perature (+25°C), unless otherwise noted.
2: For more details on Low-Power mode, refer to the “RN4870/71 Bluetooth

Low Energy Module User’s
Guide” (DS50002466).

Note 1: These measurements are done at an operating temperature of +25°C at 3.3V and are characterized
across a sample of the RN4870/71 module.
2: Measurements taken with version 1.18 firmware loaded onto the module.
3: The advertising packet data payload is approximately 15 bytes in length.
4: The amount of data being transmitted between two peer devices can affect the average current measured.
The average current measurements are done with only the necessary Bluetooth packets being exchanged
to keep the connection active at the stated interval.
