Key Features of CAN Flexibility All nodes in a CAN network are capable of initiating a transmission Flexibility – All nodes in a CAN network are capable of initiating a transmission

and receiving data

Guaranteed Latency – Calculating transmission time and response time is part y g p pof the network design.

Data Consistency – All nodes in a network either accept a message or reject it.

Strong Error Detection – Uses bit monitoring, CRCs, bit-stuffing and frame checks to ensure data integrity.

Fault Confinement – Defective nodes are switched off to prevent further network corruption.

Fault Tolerance – CAN transceivers support shorting or grounding one of the pins without corrupting the message.

High Throughput – Speeds up to 1 Mbps
