21.0
21.1
The Enhanced Controller Area Network (ECAN)
module is a serial interface, useful for communicat-
ing with other CAN modules or microcontroller
devices. This interface/protocol was designed to
allow communications within noisy environments.
The dsPIC33EPXXXGP/MC50X devices contain one
ECAN module.
The ECAN module is a communication controller
implementing the CAN 2.0 A/B protocol, as defined in
the BOSCH CAN specification. The module supports
CAN 1.2, CAN 2.0A, CAN 2.0B Passive and CAN 2.0B
Active versions of the protocol. The module implemen-
tation is a full CAN system. The CAN specification is
not covered within this data sheet. The reader can refer
to the BOSCH CAN specification for further details.

The ECAN module features are as follows:
• Implementation of the CAN protocol, CAN 1.2,
• Standard and extended data frames
• 0-8 bytes data length
• Programmable bit rate up to 1 Mbit/sec
• Automatic response to remote transmission
• Up to eight transmit buffers with application speci-
• Up to 32 receive buffers (each buffer can contain
• Up to 16 full (standard/extended identifier)
• Three full acceptance filter masks
• DeviceNet™ addressing support
• Programmable wake-up functionality with
• Programmable Loopback mode supports self-test
• Signaling via interrupt capabilities for all CAN
• Programmable clock source
• Programmable link to Input Capture module (IC2)
• Low-power Sleep and Idle mode
The CAN bus module consists of a protocol engine and
message buffering/control. The CAN protocol engine
handles all functions for receiving and transmitting
messages on the CAN bus. Messages are transmitted
by first loading the appropriate data registers. Status
and errors can be checked by reading the appropriate
registers. Any message detected on the CAN bus is
checked for errors and then matched against filters to
see if it should be received and stored in one of the
receive registers.
