Device Overview

Summary

The PIC18-Q84 family expands the 8-bit MCUs by combining an extensive array of Core Independent Peripherals (CIPs) with Controller Area Network Flexible Data Rate (CAN FD). These cost optimized MCUs contain time-saving CIPs in up to 48-pins with up to 128 KB of flash memory. The family introduces new features and peripherals like the Universal Timer (UTMR) with customization capability; context switching added to the 12-bit ADC with Computation for automating analog signal analysis for real-time system response. Additionally, it includes industry standard options, JTAG Boundary Scan, 32-bit Cyclic Redundancy Check (CRC) with memory scan on boot for added system safety.  System designers can benefit greatly by saving time, as it is significantly easier to configure a hardware-based peripheral, as opposed to writing and validating an entire software routine, to accomplish a task. 

Additional Features
  • CAN Flexible Data-Rate (FD) module:
    • Functional in CAN FD or CAN 2.0B modes
  • Eight Direct Memory Access (DMA) Controllers:
    • Data transfers capabilities
    • User programmable source and destination sizes
    • Hardware and software triggered data transfers
  • Vectored Interrupt Capability:
    • Selectable high/low priority
    • Fixed interrupt latency of three instruction cycles
    • Programmable vector table base address
    • Backwards compatible with previous interrupt capabilities
  • Analog-to-Digital Converter with Computation and Context Switching (ADC):
    • 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
    • Five internal analog channels
  • Hardware Capacitive Voltage Divider (CVD) Support:
    • Adjustable sample and hold capacitor array
    • Automates touch sampling and reduces software size and CPU usage when touch or proximity
  • Universal Timer (UTMR)
    • Two Customizable 16-bit Timers​ - Combine to create larger bit timer
  • 8-Bit Digital-to-Analog Converter (DAC):
  • Two Comparators (CMP):
  • Four 16-Bit Pulse-Width Modulators (PWM):
  • Data Signal Modulator (DSM):
  • Programmable CRC with Memory Scan:
    • Reliable data/program memory monitoring for Fail-Safe operation (e.g., Class B)
    • Calculate 32-bit CRC over any portion of Program Flash Memory
  • Communication:
    • Five UART modules:
    • LIN master and slave, DMX mode, DALI gear and device protocols
    • SPI / I2C
  • Doze: CPU and Peripherals Running at Different Cycle Rates (typically CPU is lower)
  • Idle: CPU Halted While Peripherals Operate
  • Sleep: Lowest Power Consumption
  • Peripheral Module Disable (PMD):
    • Ability to selectively disable hardware module to minimize active power consumption of unused peripherals
  • JTAG: Supports boundary scan
