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.

Interrupt:
–
–
–
Wakeup from Halt on address detection in slave mode
Three transmit mailboxes
Configurable transmit priority by identifier or order request
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):
–
–
Maskable interrupt
Software-efficient mailbox mapping at a unique address space
Successful address/data communication
Error condition
Wakeup from Halt
Mask mode permitting ID range filtering
ID list mode
