Serial Communication Peripheral (e.g., CAN Controller) Component – Computer, Electronic and Optical Product Manufacturing

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
