From the power saving perspective, the PIC24FJ DA family is targeted at low power designs. This table shows how a graphical user interface application can be used in different power saving modes. The PIC24FJ DA family can be put into the Run or Doze Mode when updating the LCD display screen. With the MCU core set at 2 MIPS and Doze Mode set at a 1:4 ratio, the family can continue to process and render graphics at the 20mA current consumption. On the other hand, the part can be put into the Idle Mode to support static screen refresh only, and therefore, the current consumption can be further reduced to 18mA. To completely save power, the MCU can turn off the LCD screen and go into Sleep Mode, and will wake up with the touch button response.
