PIC18(L)F26/45/46K40
28/40/44-Pin, Low-Power, High-Performance
Microcontrollers with XLP Technology
Description
These 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.
