tion changes accordingly.
• In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU load and
the peripherals used.
• During Deep-sleep, when the ULP co-processor is powered on, peripherals such as GPIO and I²C are able to
operate.
• The ”ULP sensor-monitored pattern” refers to the mode where the ULP coprocessor or the sensor works periodi-
cally. When touch sensors work with a duty cycle of 1%, the typical current consumption is 22

1. Device should operate in the center frequency range allocated by regional regulatory authorities. Target center frequency
range is configurable by software.
2. For the modules that use IPEX antennas, the output impedance is 50 Ω. For other modules without IPEX antennas,
users do not need to concern about the output impedance.
