TCAN1043A-Q1: replace TJA1153A about Secure HS-CAN Transceiver with Sleep Mode

Part Number: TCAN1043A-Q1

Hi, Support Team

We could replace TJA1153ATK, but customer ask NXP have Secure HS-CAN Transceiver with Sleep Mode.

New secure CAN transceiver TJA1153A provides a seamless and very cost-effective solution for securing classical CAN and CAN FD communication without cryptography. The TJA1153A belongs to a new generation of automotive high-speed CAN/CAN FD transceivers, offering security functions. It provides an interface between a classical CAN or CAN FD protocol controller and the physical two-wire CAN bus. As long as no security incidents have been detected, the TJA1153A behaves like a standard CAN transceiver with Sleep mode.

The security incidents that can be detected and contained are:

Flooding the bus from the local node
Transmitting a CAN message with an identifier that has not been assigned to the local node for transmission
Receiving a CAN message from a remote host with an identifier that is identical to one uniquely assigned to this local node
Tampered messages

Do we have same solution to replace?

if any suggestion, Please advise me.

Thanks,

Best regards,

Lawrence

  • Hi Lawrence,

    TI does not currently have any "secure CAN" transceivers available for production or sampling. We are keeping an eye on the development of this technology as cyber security is becoming only more relevant in automotive systems. 

    For now, a TI secure CAN solution would need to leverage the power of the local MCU to monitor the CAN bus traffic through a standard CAN FD transceiver such as the TCAN1044A or TCAN1043A. 

    Let me know if you have any more questions.
