C2000 Microcontroller Workshop - Communications 13 - 25
Enhanced Controller Area Network (eCAN)
Controller Area Network (CAN)
A Multi-Master Serial Bus System
 CAN 2.0B Standard
 High speed (up to 1 Mbps)
 Add a node without disturbing the bus (number of nodes not
limited by protocol)
 Less wires (lower cost, less maintenance, and more reliable)

Redundant error checking (high reliability)
 No node addressing (message identifiers)
 Broadcast based signaling

CAN does not use physical addresses to address stations. Each message is sent with an identifier
that is recognized by the different nodes. The identifier has two functions – it is used for message
filtering and for message priority. The identifier determines if a transmitted message will be
received by CAN modules and determines the priority of the message when two or more nodes
want to transmit at the same time.
