8.6.1 Overview
8.5 CAN gateway
8.6 LIN
Controller Area Network (CAN) is the definition of a high-performance communication
protocol for serial data communication. The two CAN controllers in the LPC2917/19
provide a full implementation of the CAN protocol according to the CAN specification
version 2.0B . The gateway concept is fully scalable with the number of CAN controllers,
and always operates together with a separate powerful and flexible hardware acceptance
filter.
The key features are:
The global acceptance filter provides look-up of received identifiers - called acceptance
filtering in CAN terminology - for all the CAN controllers. It includes a CAN ID look-up table
memory, in which software maintains one to five sections of identifiers. The CAN ID
look-up table memory is 2 kB large (512 words, each of 32 bits). It can contain up to 1024
standard frame identifiers or 512 extended frame identifiers or a mixture of both types. It is
also possible to define identifier groups for standard and extended message formats.
The two CAN controllers in the LPC2917/19 have the pins listed below. The CAN pins are
combined with other functions on the port pins of the LPC2917/19.
CAN pins (x runs from 0 to 1).
Table 18.
The LPC2917/19 contain two LIN 2.0 master controllers. These can be used as dedicated
LIN 2.0 master controllers with additional support for sync break generation and with
hardware implementation of the LIN protocol according to spec 2.0.
