Features
CAN Protocol
Atmel ATmega16/32/64/M1/C1
Principles
The Controller Area Network (CAN) protocol is a real-time, serial, broadcast protocol with a
very high level of security. The ATmega16/32/64/M1/C1 CAN controller is fully compatible with
the CAN Specification 2.0 Part A and Part B. It delivers the features required to implement the
kernel of the CAN bus protocol according to the ISO/OSI Reference Model:
• The Data Link Layer
• The Physical Layer
The CAN controller is able to handle all types of frames (Data, Remote, Error and Overload)
and achieves a bitrate of 1 Mbit/s.
The CAN protocol is an international standard defined in the ISO 11898 for high speed and
ISO 11519-2 for low speed.
CAN is based on a broadcast communication mechanism. This broadcast communication is
achieved by using a message oriented transmission protocol. These messages are identified
by using a message identifier. Such a message identifier has to be unique within the whole
network and it defines not only the content but also the priority of the message.
The priority at which a message is transmitted compared to another less urgent message is
specified by the identifier of each message. The priorities are laid down during system design
in the form of corresponding binary values and cannot be changed dynamically. The identifier
with the lowest binary number has the highest priority.
• Full Can Controller
• Fully Compliant with CAN Standard rev 2.0 A and rev 2.0 B
• 6 MOb (Message Object) with their own:
• 1 Mbit/s Maximum Transfer Rate at 8MHz
• TTC Timer
• Listening Mode (for Spying or Autobaud)
– 11 bits of Identifier Tag (rev 2.0 A), 29 bits of Identifier Tag (rev 2.0 B)
– 11 bits of Identifier Mask (rev 2.0 A), 29 bits of Identifier Mask (rev 2.0 B)
– 8 Bytes Data Buffer (Static Allocation)
– Tx, Rx, Frame Buffer or Automatic Reply Configuration
– Time Stamping
- the Logical Link Control (LLC) sublayer
- the Medium Access Control (MAC) sublayer
- the Physical Signalling (PLS) sublayer
- not supported - the Physical Medium Attach (PMA)
- not supported - the Medium Dependent Interface (MDI)
