Component Specifications

Definition
A specialized hardware module integrated into microcontrollers that implements the Controller Area Network (CAN) protocol, providing robust serial communication for real-time distributed control in industrial environments. It handles message framing, arbitration, error detection, and data transmission at speeds up to 1 Mbps.
Working Principle
Operates on differential signaling using CAN_H and CAN_L lines with dominant/recessive bits for collision resolution through non-destructive bitwise arbitration. Messages are transmitted as frames with identifier, control, data, and CRC fields, using CSMA/CR (Carrier Sense Multiple Access with Collision Resolution) for bus access.
Materials
Silicon semiconductor (CMOS/BiCMOS), copper bonding wires, ceramic/plastic packaging with gold-plated pins. Dielectric materials include SiO2 for insulation and polyimide for passivation.
Technical Parameters
  • Bus Pins CAN_H, CAN_L
  • Data Rate 10 kbps to 1 Mbps
  • Voltage Range 3.3V or 5V
  • Error Detection CRC-15, bit stuffing
  • Message Buffers 8-32
  • ISO 11898 Compliance Yes
  • Operating Temperature -40°C to +125°C
Standards
ISO 11898, SAE J1939, ISO 15765, DIN 72551

Frequently Asked Questions

What is the maximum cable length for CAN communication?

Up to 40 meters at 1 Mbps, extending to 1000 meters at lower speeds like 50 kbps, depending on cable quality and termination.

How does CAN handle message collisions?

Through non-destructive arbitration: lower identifier values win bus access without data loss, ensuring deterministic priority-based communication.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
