LPC2917/19
ARM9 microcontroller with CAN and LIN
8.5 CAN gateway
8.5.1
Overview
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:
Supports 11-bit as well as 29-bit identifiers
Double receive buffer and triple transmit buffer
Programmable error-warning limit and error counters with read/write access
Arbitration-lost capture and error-code capture with detailed bit position
Single-shot transmission (i.e. no re-transmission)
Listen-only mode (no acknowledge; no active error flags)
Reception of ‘own’ messages (self-reception request)
Full CAN mode for message reception
8.5.2
Global acceptance filter
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 (SFF) or 512 extended frame identifiers (EFF) or a mixture of
both types. It is also possible to define identifier groups for standard and extended
message formats.
8.5.3
CAN pin description
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.
Table 18
shows the
CAN pins (x runs from 0 to 1).

8.6 LIN
8.6.1
Overview
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.
