Microchip – Low Power PIC MCU with Integrated Crypto Engine
The PIC24F“GB2“ family of 16-bit MCUs enables secure data transfers and storage for Internet of Things and battery-powered embedded applications. This family features integrated Hardware Crypto Module, eXtreme Low Power, USB2.0 OTG and advanced peripherials. The advantage of Hardware Crypto Engine over software implementation is, less software overhead, opretates at lower CPU frequency to save power.
