TJA1043 High-Speed CAN Transceiver

For security on TJA1043, go to Secure CAN TJA1153.

The TJA1043 high-speed CAN transceiver provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1043 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1041A. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroMagnetic Discharge (ESD) performance, very low power consumption, and passive behavior when the supply voltage is turned off. Advanced features include:

Low-power management controls the power supply throughout the node while supporting local and remote wake-up with wake-up source recognition
Several protection and diagnostic functions including bus line short-circuit detection and battery connection detection
Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V

The TJA1043 implements the CAN physical layer as defined in the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007 and the pending updated version of ISO11898-2:2016). Pending the release of ISO11898-2:2016 including CAN FD and SAE-J2284-4/5, additional timing parameters defining loop delay symmetry are specified. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.

These features make the TJA1043 the ideal choice for high speed CAN networks containing nodes that need to be available all times, even when the internal V_IO and V_CC supplies are switched off.
