CAN-enabled devices are suitable for:
‧ Low traffic environments
‧ Environments where few messages (up to 6) must
be received and processed by the system
‧ Environments where no or few back-to-back
transmissions of large quantities of information
are required.
ECAN, on the other hand, is recommended for:
‧ High traffic environments
‧ Environments where the system must select,
receive and process a larger number of
messages (typically up to 16 messages). For this
type of environment, the Mode 1 (Enhanced
Legacy) is very well suited as up to 16
programmable filters are available. DeviceNet?
and CanOpen are good examples of networks
that can take good advantage of an ECAN
module in Mode 1 (Enhanced Legacy) due to the
large quantity of messages that can be handled
with minimal processing overhead. Another
advantage to DeviceNet networks in this mode is
the use of data byte filters that further extend the
filtering capabilities of the device.
Environments where back-to-back transmissions
of large quantities of information are required. In
this case, the Mode 2 (FIFO mode) is particularly
suitable as it handles bursts of data in a very
straightforward manner. Bootloaders are a good
example of such systems that may take advantage
of an ECAN module in Mode 2 (FIFO), as the
microcontroller can handle a complete 64 bytes
simultaneous programming sequence per burst
