The vast majority of low-power applications require one or more of these features. nanoWatt XLP Technology combines all three in a comprehensive portfolio of devices. Whether it is extended battery life, sealed batteries, or the integration of energy harvesting, Microchips 8- and 16-bit PIC MCUs with nanoWatt XLP Technology provide more freedom for designers that need their products to operate longer using less power, or requiring fewer battery changes.
