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:
The TJA1152, part of the EdgeLock Assurance program, is designed to meet industry standards and follows NXP's security-by-design approach.
