Abstract

A system to improve CAN communications between microcontrollers, where the CAN Transceiver is completely discarded and replaced with a galvanic isolated solution. With the proposed solution, it is possible to obtain CAN data transfer rates of 8 Mbps (however theoretically can go as high as baud rates of 12 Mbps depending on the type of galvanic isolation) while ensuring galvanic isolation between microcontrollers. It balances reducing the necessary hardware while maintaining or outperforming all the functionalities that a CAN transceiver with full galvanic isolation implemented would provide. The discrete hardware has a wide range of operability in different scenarios from wide voltage ranges or no common ground while being ideal for high speed transfers between microcontrollers while maintaining all the advantages that a CAN communication provides, either be built in error detection or robustness with bit monitoring, bit stuffing, frame check, acknowledgement check and cyclic redundancy check.
