2. The current consumption figures in RX mode are for cases when the peripherals are disabled and the

CPU is idle.

Table 6 Current Consumption Depending on Work Modes

Note:

●

When measuring Modem-sleep power consumption data, the CPU is in working state and the cache is in

idle state.

●

In the scenario where Wi-Fi is turned on, the chip will switch between Active and Modem-sleep modes,

and the power consumption will also change between the two modes.

●

In Modem-sleep mode, the CPU frequency changes automatically, and the frequency depends on the CPU

load and peripherals used.

●

In Deep-sleep mode, only when the ULP coprocessor is in working state, GPIO and low-power I2C can be

operated.

●

When the system is in the ultra-low power sensor monitoring mode, the ULP coprocessor or sensor works

periodically. The touch sensor works with a 1% duty cycle, and the system power consumption is typically

22 µA.
