Image of NXP's TJA1152 and TJA1153 Secure CAN Transceivers NXP’s TJA1152 and TJA1153 secure CAN transceivers provide a seamless and cost-effective solution for securing classical CAN and CAN FD communication without cryptography. The TJA1152 and TJA1153 belong to a generation of automotive high-speed CAN/CAN FD transceivers offering security functions. They provide 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 TJA1152 behaves like a standard CAN transceiver with standby mode while the TJA1153 offers sleep mode.

Security incidents that can be detected and contained:

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
