Secure HS-CAN transceiver with Standby mode and VIO pin

NXP's new secure CAN transceiver TJA1152 provides a seamless and very cost-effective solution for securing classical CAN and CAN FD communication without cryptography. The

TJA1152 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 TJA1152 behaves like a standard CAN transceiver with Standby 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
