PIC18 Q43 Analog Peripherals
• Analog-to-Digital Converter with Computation (ADC2): – Up to 43 external channels – Automated math functions on input signals: • Averaging, filter calculations, oversampling and threshold comparison – Operates in Sleep – Five internal analog channels – Hardware Capacitive Voltage Divider (CVD) Support: • Adjustable sample and hold capacitor array • Guard ring digital output drive • Automates touch sampling and reduces software size and CPU usage when touch or proximity sensing is required • 8-Bit Digital-to-Analog Converter (DAC): – Buffered output available on two I/O pins – Internal connections to ADC and Comparators • Two Comparators (CMP): – Four external inputs – Configurable output polarity – External output via Peripheral Pin Select • Zero-Cross Detect (ZCD): – Detect when AC signal on pin crosses ground • Voltage Reference: – Fixed Voltage Reference with 1.024V, 2.048V and 4.096V output levels – Internal connections to ADC, Comparator and DAC
Clocking Structure
• High-Precision Internal Oscillator Block (HFINTOSC): – Selectable frequencies up to 64 MHz – ±1% at calibration – Active Clock Tuning of HFINTOSC for better accuracy • 32 kHz Low-Power Internal Oscillator (LFINTOSC) • External 32 kHz Crystal Oscillator (SOSC) • External High-frequency Oscillator Block: – Three crystal/resonator modes – Digital Clock Input mode – 4x PLL with external sources • Fail-Safe Clock Monitor: – Allows for operational recovery if external clock stops • Oscillator Start-up Timer (OST): – Ensures stability of crystal oscillator sources © 2019 Microchip Technology Inc.
