CAN 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:
• 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

The PIC18-Q83 family expands the 8-bit MCUs by combining an extensive array of Core Independent Peripherals (CIPs) with Controller Area Network (CAN). 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.
