Microchip's PIC18F "K22" MCUs provide features such as operation from 1.8 to 5.5V, numerous communication channels, 8 to 128KB flash memory, and peripherals for mTouch™ capacitive touch-sensing applications. The feature set of the PIC18F "K22" MCUs allows this family to be used in a wide variety of applications.

The 5V capability of the family is ideal for applications that typically require robust operation or noise immunity. Battery-powered applications benefit from nanoWatt XLP technology, which reduces current draw and therefore extends battery life.
