PIC18FXXQ84
– Automatic checksums – Programmable 1, 1.5, and two Stop bits – Wake-up on BREAK reception – DMA compatible • Two SPI modules: – Configurable length bytes – Arbitrary length data packets – Transmit-without-receive and receive-without-transmit options – Transfer byte counter – Separate transmit and receive buffers with 2-byte FIFO and DMA capabilities • One I2C module, SMBus, PMBus™ Compatible: – 7-bit and 10-bit addressing modes with address masking modes – Dedicated address, transmit and receive buffers and DMA capabilities – Bus collision detection with arbitration – Bus time-out detection and handling – I2C, SMBus 2.0 and SMBus 3.0, and 1.8V input level selections – Multi-Master mode, including self-addressing • Device I/O Port Features: – 25 I/O pins (PIC18F26/27Q84) – 36 I/O pins (PIC18F46/47Q84) – 44 I/O pins (PIC18F56/57Q84) – Individually programmable I/O direction, open-drain, slew rate and weak pull-up control – Interrupt-on-change on most pins – Three programmable external interrupt pins • Peripheral Pin Select (PPS): – Enables pin mapping of digital I/O
Analog Peripherals
• Analog-to-Digital Converter with Computation and Context Saving (ADC3): – Up to 43 external channels – Automated math functions on input signals: • Averaging, filter calculations, oversampling and threshold comparison – 4 Separate Contexts (settings and results) saved and accessible separately – Contexts can be accessed through firmware or DMA – 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): © 2019 Microchip Technology Inc.
