Main Characteristics • Multi-Master Bus Access • Message Broadcasting • Message Priority (No Node IDs) • Limited Data Length (0…8 bytes) • 1 Mbit/sec Data Rate • Excellent Error Detection & Fault Confinement © esd electronics, Inc. • 525 Bernardston Road • Greenfield, MA 01301 Page 14
Main Benefit: Benefits of Using CAN • Physical and Data Link Layer implemented in Silicon • SW Development Engineer is not involved with writing protocol features • Low Cost Implementation ISO 11898 7-Layer Reference Be aware! Whenever you attempt to add software functions between the CAN Data Link Layer and the Application Layer, you will be adding functionalities that are already covered by off-the-shelf available higher layer protocols such as CANopen and DeviceNet. © esd electronics, Inc. • 525 Bernardston Road • Greenfield, MA 01301 Page 15
