Figure 9. CAN physical transceiver circuit
The LPC55Sxx CAN-FD module is a full implementation of the CAN protocol specification, the CAN with Flexible Data rate (CAN
FD) protocol and the CAN 2.0 version B protocol, which supports both standard and extended message frames and long payloads
up to 64 bytes transferred at faster rates up to 8 Mbps. Like most others CAN physical transceivers, the CANH and CANL are
available for the designer to terminate bus depending on the application.
Figure 9 and Figure 10 show examples of the CAN
node terminations.
