PIC16(L)F18326/18346
Full-Featured, 14/20 Low Pin Count Microcontrollers with XLP
Description
PIC16(L)F18326/18346 microcontrollers feature Analog, Core Independent Peripherals and Communication
Peripherals, combined with eXtreme Low Power (XLP) for a wide range of general purpose and low-power applications.
The Peripheral Pin Select (PPS) functionality enables pin mapping when using the digital peripherals (CLC, CWG, CCP,
PWM and communications) to add flexibility to the application design.
