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
    • Reduced system electrical noise while performing ADC conversions
  • Peripheral Module Disable (PMD):
    • Ability to selectively disable hardware modules to minimize active power consumption of unused peripherals
  • Analog Peripheral Manager:
    • Can be used to optimize power consumption in applications that use analog peripherals by switching them on and off as needed, core independently using dedicated timer resources
  • Low Power Mode Features:
    • Sleep:
      • < 900 nA typical @ 3V/25°C (WDT enabled)
      • < 600 nA typical @ 3V/25°C (WDT disabled)
    • Operating Current:
      • 48 µA typical @ 32 kHz, 3V/25°C
      • < 1 mA typical @ 4 MHz, 5V/25°C
