PIC18LF47K40-I/ML

These PIC18(L)F27/47K40 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.
