PIC18FXXQ84
– 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
Programming/Debug Features
• In-Circuit Serial Programming™ (ICSP™) via Two Pins • In-Circuit Debug (ICD) with Three Breakpoints via Two Pins • Debug Integrated On-Chip © 2019 Microchip Technology Inc.
