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 V_IO supply pin
- The TJA1153 is a secure-CAN transceiver with sleep mode
- The V_IO 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 V_CC and V_IO
- Thermally protected
