Low Power

Integrated Analog Icon

Capture and count external events and use interrupts to trigger events even in power down mode.

RTCC has higher integration with no external chip and continues operation while in power saving modes. Quadrature Encoder Interface (QEI) obtains signed velocity and relative rotor position of the motor

PTG: Peripheral Trigger Generator
+

The Peripheral Trigger Generator (PTG) module, in 16-bit dsPIC33/PIC24 devices, is a core independent user-programmable sequencer, which is capable of generating triggers with complex input signal sequences to coordinate the operation of other peripherals. Learn how PTG can be used in conjecture with other peripheral modules like the ADC, Output Compare (OC) , PWM and Timers to benefit your application here:

Dual Partition Flash
+

Newer PIC24F/dsPIC33 MCU’s feature dual-partition Flash with Live Update capability. These devices can hold two independent software applications, permitting the simultaneous programming of one partition while executing application code from the other . To learn more on how dual partition flash with live update can enable execution from one part of the memory while updating your code at the same time:

Vbat: Vbattery
+

Vbat modes is a hardware-based power mode that maintains only the most critical operations when a power loss occurs on VDD. In this mode, the power to these systems is from a backup power source connected to the VBAT pin. Also in this mode, the Real Time Clock/Calendar (RTCC) remains functional and contents of retention registers are maintained. To learn more about this low power mode:
