The new PIC18F K-series microcontrollers are the highest performing members of the PIC18F family operating at up to 64MHz and 16 MIPS of processing speed. They have an operating voltage range of 1.8V to 3.6V, 100K write endurance, and typical 40 year retention for both Flash and EEPROM memory. The K-series adds diversity to the PIC18F family and provides a variety of options to meet design requirements.
