描述 Description

PIC18F24/25Q10 microcontrollers feature Analog, Core Independent, and Communication Peripherals for

a wide range of general purpose and low-power applications. These 28 -pin devices are equipped with a

10-bit ADC with Computation (ADC2

) 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
