nRF52

Lesson 14 – nRF5x Power Management Tutorial Power modes:

• System On (mA)
  • Subpower modes:
    • Constant latency: constant latency on the expense of higher current. This is done by keeping all internal voltage regulators and oscillators running.
      • NRF_POWER→TASKS_CONSTLAT = 1;
      • HF clock always ON
    • Low power (default) aka variable latency
      • lower current on the expense of latency.
      • The internal regulators and oscillators will be switched on/off automatically by the PMU based on the peripherals/system blocks demand.
• System Off (<1uA)
