10.0
The PIC24FJ128GA310 family of devices provides the
ability to manage power consumption by selectively
managing clocking to the CPU and the peripherals. In
general, a lower clock frequency and a reduction in the
number of circuits being clocked reduces consumed
power.
PIC24FJ128GA310 family devices manage power
consumption with five strategies:
• Instruction-Based Power Reduction Modes
• Hardware-Based Power Reduction Features
• Clock Frequency Control
• Software Controlled Doze Mode
• Selective Peripheral Control in Software
Combinations of these methods can be used to
selectively tailor an application’s power consumption,
while still maintaining critical application features, such
as timing-sensitive communications.

In addition to full-power operation, otherwise known as
Run mode, the PIC24FJ128GA310 family of devices
offers three Instruction-Based, Power-Saving modes
and one Hardware-Based mode:
• Idle
• Sleep (Sleep and Low-Voltage Sleep)
• Deep Sleep
• V
All four modes can be activated by powering down dif-
ferent functional areas of the microcontroller, allowing
progressive reductions of operating and Idle power
consumption. In addition, three of the modes can be
tailored for more power reduction, at a trade-off of
some operating features.
