Secure HS-CAN Transceiver with Standby Mode
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
製品詳細
Features
General
- The TJA1152A is a secure HS-CAN transceiver with Standby mode and a VIO supply pin. The VIO pin allows for direct interfacing with 3.3 V and 5 V microcontrollers.
- The TJA1152B is a secure HS-CAN transceiver with Standby mode.
- ISO 11898-1:2015, ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant
- Operates in classical CAN and CAN FD systems with arbitration phase bit rate set at 125 kbit/s, 250 kbit/s or 500 kbit/s
- For arbitration bit rates of 250 kbit/s and 500 kbit/s, the fast phase bit rate can be set to two or four times the arbitration bit rate
- AEC-Q100 Rev-G qualified (grade 1)
- Low electromagnetic emission (EME) and high electromagnetic immunity (EMI)
- SO8 plastic small outline package
System Control and Diagnostic Features
- Mode control via dedicated control pin STB
- Overtemperature shutdown
Security Features
- Spoofing protection
- Flooding protection
- Tamper protection
Predictable and Fail-Safe Behavior
- Functional behavior predictable under all supply conditions
- Transceiver disengages from bus when not powered (zero load)
- Transmit data (TXD) dominant time-out function
- Internal biasing of TXD and STB input pins
Protection
- High ESD handling capability on the bus pins (8 kV HBM)
- Bus pins protected against transients in automotive environments
- Undervoltage detection on pins VCC and VIO
- Thermally protected
