PIC24FJ256GA412/GB412 FAMILY
16-Bit Flash Microcontrollers with Dual Partition Flash Memory,
XLP, LCD, Cryptographic Engine and USB On-The-Go
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
