PIC18(L)F26/45/46K40
28/40/44-Pin, Low-Power, High-Performance
Microcontrollers with XLP Technology
Description
PIC18(L)F26/45/46K40 microcontrollers feature Analog, Core Independent Peripherals and Communication
Peripherals, combined with eXtreme Low-Power (XLP) technology for a wide range of general purpose and low-power
applications. These 28/40/44-pin devices are equipped with a 10-bit ADC with Computation (ADCC) automating
Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling and
performing automatic threshold comparisons. They also offer a set of Core Independent Peripherals such as
Complementary Waveform Generator (CWG), Windowed Watchdog Timer (WWDT), Cyclic Redundancy Check (CRC)/
Memory Scan, Zero-Cross Detect (ZCD) and Peripheral Pin Select (PPS), providing for increased design flexibility and
lower system cost.
