Abstract: A transceiver for sending and receiving data from a controller area network (CAN) bus is disclosed. The transceiver includes a microcontroller port, a transmitter and a receiver. The transceiver is configured to receive a data frame from a microcontroller via the microcontroller port and to determine if the microcontroller is authorized to send the data frame or part of it based on a message identifier in the data frame and the outcome of the arbitration process. If the microcontroller is unauthorized to send the data, the transceiver is configured to invalidate the data frame and disconnect the microcontroller from the CAN bus for a predetermined period.

Abstract: A transceiver for sending and receiving data from a controller area network (CAN) bus is disclosed. The transceiver includes a microcontroller port, a transmitter and a receiver, wherein the transceiver is configured to determine bit timings from a data frame received by the receiver. The transceiver is further configured to detect attempts to introduce a signal glitch in a predetermined portion of the data frame and upon detection of the signal glitch, the transceiver is configured to invalidate the data frame on a transmission line and/or disable the transmitter for a predetermined period.

Abstract: A transceiver for sending and receiving data from a controller area network (CAN) bus is disclosed. The transceiver includes a microcontroller port, a transmitter and a receiver. The transceiver is configured to detect a CRC delimiter or an error signal in a CAN frame and after the detection, allow a microcontroller coupled with the microcontroller port to only send a predetermined data pattern until a bus idle is detected.
