Extreme Low-Power Features
• Multiple Power Management Options for Extreme Power
Reduction:
- VBAT allows for lowest power consumption on backup battery (with or without RTCC)
- Deep Sleep allows near total power-down with the ability to wake-up on external triggers
- Sleep and Idle modes selectively shut down peripherals and/or core for substantial power reduction and fast wake-up
- Doze mode allows CPU to run at a lower clock speed than peripherals
• Alternate Clock modes allow On-the-Fly Switching to a Lower Clock Speed for Selective Power Reduction
• Extreme Low-Power Current Consumption for Deep Sleep:
- WDT: 650 nA @ 2V typical
- RTCC: 650 nA @ 32 kHz, 2V typical
- Deep Sleep current, 60 nA typical
• 160 A/MHz in Run mode
