3.10 CAN Transceivers

The PIC32CM SG00/GC00 Curiosity Pro development board features the CAN protocol version 2.0 A/B which includes the CAN Flexible Data Rate Frame format (CAN-FD, ISO 11898-1:2015) by means of two CAN transceivers, ATA6561 on the J502 and J503 connectors. For additional information about the CAN transceivers, refer to the “ATA6561 Data Sheet” (DS20005991) available at product webpage.

The schematic includes TVS diodes protection (D550 and D501) and switches (SW500 and SW501) if it is required to disconnect the impedance (62 ohms + 62 ohms).
