Note:
1. The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient
temperature at the RF port. All transmitters’ measurements are based on a 100% duty cycle.
2. The current consumption figures in RX mode are for cases when the peripherals are
disabled and the CPU is idle.

Note:
1. The current consumption figures in Modem-sleep mode are for cases where the CPU is
powered on and the cache idle.
2. When Wi-Fi is enabled, the chip may switch between Active and Modem-sleep modes.
Therefore, current consumption changes accordingly.
3. In practice, software can adjust CPU’s frequency according to CPU load to reduce current
consumption.
