Frequently Asked Questions
Does the PIC18F8680-I/PT include a built-in CAN controller, and what CAN version does it support?
Yes, the PIC18F8680-I/PT integrates a full CAN 2.0B Active controller with 3 transmit and 2 receive buffers, supporting both standard 11-bit and extended 29-bit identifiers. The on-chip CAN module connects directly to an external CAN transceiver (such as MCP2551) to form a complete node on industrial or automotive CAN networks at speeds up to 1 Mbps.
For a real-time motor-control design running at 40 MHz, how much instruction throughput does the PIC18F8680-I/PT provide?
The PIC18F8680-I/PT executes most PIC18 instructions in a single 25 ns cycle at 40 MHz, yielding up to 10 MIPS of throughput. This is sufficient for concurrent PID control loops at 10 kHz update rates while simultaneously handling CAN communication, ADC sampling, and PWM generation without a DSP co-processor.
How many ADC input channels does the PIC18F8680-I/PT support, and what is the converter resolution?
The device includes a 10-bit successive-approximation ADC with up to 16 multiplexed input channels, sampling at up to 100 ksps. This enables simultaneous monitoring of multiple current, voltage, or temperature sensors in a motor drive or power management system, with each channel delivering 1024 discrete levels of resolution.
In a design requiring an upgrade from PIC18F6680 to a higher-pin-count variant, how compatible is PIC18F8680-I/PT?
The PIC18F8680 is a direct upward migration from PIC18F6680, sharing the same PIC18 instruction set and peripheral register map. The 80-pin TQFP package adds 20 more I/O pins over the 64-pin TQFP of the 6680, providing additional ADC channels and GPIO without re-writing firmware logic, only extending the I/O initialization code.
