Additionally, the K-series has a total of seven different power management modes providing a variety of options for power conservation. Each of these modes determines which areas of the microcontroller are clocked and their clock speed. Enhancements include a 1µA idle mode and a 0.1µA low-powered Sleep mode. Also, the clock switching feature allows the low-power, 32kHz oscillator to be used as the primary clock source. All of these features make the new PIC18FXXK20 ideal for battery operated applications.
