PIC18FXXQ84
• 48µA @ 32 kHz, 3V, typical
Digital Peripherals
• Four 16-Bit Pulse-Width Modulators (PWM): – Dual outputs for each PWM module – Integrated 16-bit timer/counter – Double-buffered user registers for duty cycles – Right/Left/Center/Variable aligned modes of operation – Multiple clock and Reset signal selections • Three 16-Bit Timers (TMR0/1/3) • Three 8-Bit Timers (TMR2/4/6) with Hardware Limit Timer (HLT) • Two Universal Timers (TMRU16A/16B): – New Timer modules with features of TMR0/TMR1/TMR2 (Gate, Hardware Limit) – Two 16-bit timers can be chained together to create a combined 32-bit timer • Eight Configurable Logic Cell (CLC): – Integrated combinational and sequential logic • Three Complimentary Waveform Generators (CWG): – Rising and falling edge dead-band control – Full-bridge, half-bridge, 1-channel drive – Multiple signal sources – Programmable dead band – Fault-shutdown input • Three Capture/Compare/PWM (CCP) modules: – 16-bit resolution for Capture/Compare modes – 10-bit resolution for PWM mode • Three Numerically Controlled Oscillators (NCO): – Generates true linear frequency control and increased frequency resolution – Input clock up to 64 MHz • Signal Measurement Timer (SMT): – 24-bit timer/counter with prescaler – Several modes of operation like Time-of-Flight, Period and Duty Cycle measurement, etc. • Data Signal Modulator (DSM): – Multiplex two carrier clocks, with glitch prevention feature – Multiple sources for each carrier • Programmable CRC with Memory Scan: – Reliable data/program memory monitoring for Fail-Safe operation (e.g., Class B) – Calculate 16-bit CRC over any portion of Program Flash Memory • CAN Flexible Data-Rate (FD) module: – Functional in CAN FD or CAN 2.0B modes – One dedicated transmit FIFO – Three Programmable Transmit/Receive FIFOs – One Transmit Event Queue – 12 Acceptance Masks/Filters – Calculate 16-bit CRC over any portion of Program Flash Memory • Five UART modules: – LIN master and slave, DMX mode, DALI gear and device protocols – Asynchronous UART, RS-232, RS-485 compatible – Automatic and user timed BREAK period generation © 2019 Microchip Technology Inc.
