  • In Modem Sleep modes, power consumption may increase depending on flash memory access.
  • In Deep Sleep (ULP active) modes, while the ULP coprocessor is running, internal peripherals such as GPIO and I2C may continue operating.

  • All measurements were performed at an ambient temperature of 25 °C with a 3.3 V supply voltage.
  • Transmit mode measurements were carried out with a 100% duty cycle.
  • During receive mode measurements, all peripherals were disabled and the CPU was idle.
