Microchip Technology PIC18F4xK20 Flash MCUs

Microchip Technology PIC18F4xK20 Flash Microcontrollers offer the advantages of PIC18 MCUs with the addition of high-endurance Flash program memory. Microchip PIC18F4xK20 MCUs are available with 28- and 40/44-pin packages and Flash memory up to 64KB. Microchip PIC18FK4xK20 are nanoWatt XLP MCUs that incorporate a range of features that can significantly reduce power consumption during operation, including alternate run modes, multiple idle modes, on-the-fly mode switching, and low consumption in key modules. The design enhancements included in these Microchip Technology devices make them ideal for many high-performance, power-sensitive applications.
