Frequently Asked Questions
What CAN protocol version does the PIC18F6680-I/PT support, and what bus speeds can it achieve?
The PIC18F6680-I/PT integrates a full CAN 2.0B active controller supporting standard and extended frame formats at bus speeds up to 1 Mbps. Running the PIC18 core at 40 MHz provides enough timing resolution to generate accurate bit timing for all standard CAN baud rates from 10 kbps to 1 Mbps, making it compatible with both low-speed automotive body networks and high-speed industrial CAN-open or DeviceNet segments.
How does the PIC18F6680-I/PT's 52 I/O pin count benefit industrial control designs compared to smaller 40-pin PIC18 variants?
With 52 general-purpose I/O pins in the 64-pin TQFP-64 package, the PIC18F6680-I/PT can directly interface relay outputs, digital inputs, SPI displays, UART modems, and CAN transceivers simultaneously without any external port expander ICs. A comparable 40-pin PIC18 offers only about 33 I/O pins, which forces designers to add I2C expanders, adding cost, latency, and board complexity when 40 or more signals are needed in a single control node.
For a factory automation controller running at 40 MHz, how does the PIC18F6680-I/PT handle concurrent CAN communication and ADC sampling?
The PIC18F6680-I/PT uses dedicated hardware CAN message buffers and interrupt-driven reception, so the 8-bit CPU at 40 MHz can continue sampling the 10-bit ADC and executing control algorithms while CAN frames are being received or transmitted autonomously. Each received CAN message triggers an interrupt in under 2 µs at 1 Mbps bus speed, and the hardware acceptance filter lets the MCU selectively process only the relevant 11-bit or 29-bit message IDs, keeping CPU overhead below 10% even at full 1 Mbps load.
