PIC16(L)F18426/46
14/20-Pin Full-Featured, Low Pin Count Microcontrollers
with XLP
Description
PIC16(L)F184XX microcontrollers feature Intelligent Analog, Core Independent Peripherals (CIPs) and
communication peripherals combined with eXtreme Low-Power (XLP) for a wide range of general
purpose and low-power applications. Features such as a 12-bit Analog-to-Digital Converter with
Computation (ADC2), Memory Access Partitioning (MAP), the Device Information Area (DIA), Power-
saving operating modes, and Peripheral Pin Select (PPS), offer flexible solutions for a wide variety of
custom applications.
