描述 Description

PIC18(L)F67K40 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 64-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.
