29 Power-Saving Features

Note: This data sheet summarizes the features of the dsPIC33CK512MPT608 family of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to “Watchdog Timer and Power-Saving Modes” (www.microchip.com/DS70615) in the “dsPIC33/PIC24 Family Reference Manual”.

The dsPIC33CK512MPT608 family devices provide 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 peripherals being clocked constitutes lower consumed power.

dsPIC33CK512MPT608 family devices can manage power consumption in four ways:

  • Clock Frequency
  • Instruction-Based Sleep and Idle modes
  • 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.
