Power-Saving Functionality

  • Doze: CPU and Peripherals Running at Different Cycle Rates (Typically CPU Is Lower)
  • Idle: CPU Halted While Peripherals Operate
  • Sleep: Lowest Power Consumption
  • Peripheral Module Disable (PMD):
    • Ability to selectively disable hardware module to minimize active power consumption of unused peripherals
  • Low-Power Mode Features:
    • Sleep: < 1 µA typical @ 3V
    • Operating current:
      • 48 µA @ 32 kHz, 3V, typical
