NXP Semiconductors TJA115x Secure CAN Transceivers

NXP Semiconductors TJA115x Secure CAN Transceivers provide a seamless and cost-effective solution for securing classical CAN and CAN FD communication without cryptography. The TJA115x belongs to a generation of automotive high-speed CAN/CAN FD transceivers, offering security functions. It interfaces 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 NXP Semiconductors TJA1152 behaves like a standard CAN transceiver with standby mode.

Features

  • General
    • The TJA1152A is a secure HS-CAN transceiver with standby mode and a VIO supply pin
    • The TJA1153 is a secure-CAN transceiver with sleep mode
    • The VIO pin allows for direct interfacing with 3.3V and 5V 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 125kbit/s, 250kbit/s or 500kbit/s
    • For arbitration bit rates of 250kbit/s and 500kbit/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 the 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 (8kV HBM)
    • Bus pins protected against transients in automotive environments
    • Undervoltage detection on pins VCC and VIO
    • Thermally protected
