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: < 800 nA typical @ 1.8V
    • Operating Current:
      • 48 µA @ 32 kHz, 3V, typical
