Preliminary data sheet
7.10.1 Features
7.11.1 Features
7.11 C_CAN controller
receivers can operate in either master or slave mode, depending on whether the chip has
to initiate a data transfer or is only addressed. The I
controlled by more than one bus master connected to it.
Controller Area Network (CAN) is the definition of a high performance communication
protocol for serial data communication. The C_CAN controller is designed to provide a full
implementation of the CAN protocol according to the CAN Specification Version 2.0B. The
C_CAN controller allows to build powerful local networks with low-cost multiplex wiring by
supporting distributed real-time control with a very high level of security.
On-chip C_CAN drivers provide an API for initialization and communication using CAN
and CANopen standards.

The I
I
Easy to configure as master, slave, or master/slave.
Programmable clocks allow versatile rate control.
Bidirectional data transfer between masters and slaves.
Multi-master bus (no central master).
Arbitration between simultaneously transmitting masters without corruption of serial
data on the bus.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer.
The I
The I
Conforms to protocol version 2.0 parts A and B.
Supports bit rate of up to 1 Mbit/s.
Supports 32 Message Objects.
Each Message Object has its own identifier mask.
Provides programmable FIFO mode (concatenation of Message Objects).
Provides maskable interrupts.
Supports Disabled Automatic Retransmission (DAR) mode for time-triggered CAN
applications.
Provides programmable loop-back mode for self-test operation.
The C_CAN API includes the following functions:
– C_CAN set-up and initialization
– C_CAN send and receive messages
