CYBERSECURITY FEATURE The TJA1152 Secure CAN transceiver features stand-by mode and the TJA1153 supports sleep mode; both are compliant with ISO 11898-2:2016. reconfigure the transceiver using a secure boot microcontroller. This should be done only in the first few seconds after the microcontroller goes through a secure boot to prevent a runtime compromised ECU from updating the Secure CAN transceiver's configured CAN-IDs or flooding thresholds maliciously. The Secure CAN transceivers have a configurable parameter that can be set to ensure this limited time window for configurability. Secure CAN transceivers such as TJA1152 and TJA1153 are key enablers for addressing challenges for CV cybersecurity. The transceivers are available as drop-in replacements to legacy CAN HS (high-speed) and CAN FD transceivers, facilitating a simple populating of the transceiver in an application. The transceivers serve as a one-size-fits-all security solution for Tier-1s that are implementing security across a wide variety of commercial-vehicle OEMs. An initial configuration of the transceivers is sufficient to secure vehicles equipped with a different mix of legacy and new ECUs, and varying levels of software flexibility, while reducing cost for network security. The Secure CAN transceivers have configurable pass and block lists for CAN-IDs, rate limiting, and an integrated CAN controller for generating error frames and switching to secure mode (bus off for TX).
