PIC16(L)F18326/46 MCUs with XLP Microchip Technology PIC16(L)F18326/46 MCUs with eXtreme Low Power (XLP) are full-featured MCUs with a low pin count. These MCUs feature analog, core independent peripherals, and communication peripherals with XLP for various general-purpose and low-power applications. The PIC16(L)F18326/46 MCUs offer Peripheral Pin Select (PPS) functionality. This enables pin mapping when using digital peripherals (CLC, CWG, CCP, PWM, and communications) to add flexibility to the application design. The PIC16(L)F18326 MCUs are offered in 14-pin PDIP, SOIC, TSSOP packages, and 16-pin UQFN packages. The PIC16(L)F18346 MCUs come in 20-pin PDIP, SOIC, SSOP, and UQFN packages.
