Microchip has fitted out its latest offspring with some interesting new features which will be unfamiliar to developers who have grown up with other PIC devices. In this article we will look briefly at two of these novelties: high-endurance flash (HEF), which is a region of extra-robust flash storage that the microcontroller can write to and read from; and programmable logic cells which let you configure hardware in the microcontroller, which can save a lot of code and computing resources.
