Frequently Asked Questions
How much Flash and RAM does the PIC18F2682-E/SO provide and is it enough for a CANopen node stack?
The PIC18F2682-E/SO includes 80 KB of self-programmable Flash and 3328 bytes of RAM. A lightweight CANopen node stack typically requires 20 KB to 40 KB of Flash and 500 bytes to 1 KB of RAM, so this device comfortably hosts the protocol stack alongside application firmware with headroom to spare for future feature additions.
Does the PIC18F2682-E/SO include a hardware CAN controller, and which CAN standard does it support?
Yes, the PIC18F2682-E/SO integrates a CAN 2.0B active controller supporting both standard 11-bit and extended 29-bit frame identifiers at bit rates up to 1 Mbps. This makes it directly applicable to automotive OBD-II interfaces, industrial CANopen nodes, and DeviceNet adapters without requiring an external CAN controller chip.
What ADC resolution and channel count are available on the PIC18F2682-E/SO for analog sensor acquisition?
The PIC18F2682-E/SO provides a 10-bit ADC with 13 multiplexed input channels. At 40 MHz system clock this ADC can complete a conversion in under 20 µs, which is fast enough to sample multiple temperature, pressure, and current sensors sequentially within a 1 ms control loop period in industrial equipment.
For a compact CAN node on a sensor board, how small is the PIC18F2682-E/SO package and what operating temperature range does it cover?
The PIC18F2682-E/SO comes in a 28-pin SOIC package with a body width of 7.5 mm and a pin pitch of 1.27 mm, occupying a modest PCB footprint. The E-grade variant is rated from -40°C to +125°C, supporting deployment in engine bay modules, outdoor industrial enclosures, and other locations with extreme ambient temperature swings.
