Product overview
Interrupt:
Successful address/data communication
Error condition
Wakeup from Halt
Wakeup from Halt on address detection in slave mode
5.9.5
Controller area network interface (beCAN)
The beCAN controller (basic enhanced CAN), interfaces the CAN network and supports the
CAN protocol version 2.0A and B. It is equipped with a receive FIFO and a very versatile
filter bank. Together with a filter match index, this allows a very efficient message handling in
today’s car network architectures. The CPU is significantly unloaded. The maximum
transmission speed is 1 Mbit/s.
Transmission
Three transmit mailboxes
Configurable transmit priority by identifier or order request
Reception
11- and 29-bit ID
1 receive FIFO (3 messages deep)
Software-efficient mailbox mapping at a unique address space
FMI (filter match index) stored with message for quick message association
Configurable FIFO overrun
Time stamp on SOF reception
6 filter banks, 2 x 32 bytes (scalable to 4 x 16-bit) each, enabling various masking
configurations, such as 12 filters for 29-bit ID or 48 filters for 11-bit ID.
Filtering modes (mixable):
Mask mode permitting ID range filtering
ID list mode
Interrupt management
Maskable interrupt
Software-efficient mailbox mapping at a unique address space

Input/output specifications
The product features four I/O types:
Standard I/O 2 MHz
Fast I/O up to 10 MHz
High sink 8 mA, 2 MHz
True open drain (I
To decrease EMI (electromagnetic interference), high sink I/Os have a limited maximum
slew rate. The rise and fall times are similar to those of standard I/Os.
