Power-Saving Functionality

  • Doze: CPU and peripherals running at different cycle rates (CPU is typically slower)
  • 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
