TJA1043T/1J Overview

For security on TJA1043, go to Secure CAN TJA1153.The TJA1043 high-speed CAN transceiver provides an interface between a ControllerArea Network (CAN) protocol controller and the physical two-wire CAN bus. Thetransceiver is designed for high-speed CAN applications in the automotive industry,providing differential transmit and receive capability to (a microcontroller with) a CANprotocol controller.The TJA1043 belongs to the third generation of high-speed CAN transceivers from NXPSemiconductors, offering significant improvements over first- and second-generationdevices such as the TJA1041A. It offers improved ElectroMagnetic Compatibility (EMC)and ElectroMagnetic Discharge (ESD) performance, very low power consumption, andpassive behavior when the supply voltage is turned off. Advanced features include:Low-power management controls the power supply throughout the node whilesupporting local and remote wake-up with wake-up source recognitionSeveral protection and diagnostic functions including bus line short-circuit detectionand battery connection detectionCan be interfaced directly to microcontrollers with supply voltages from 3 V to 5 VThe 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, additionaltiming parameters defining loop delay symmetry are specified. This implementationenables reliable communication in the CAN FD fast phase at data rates up to 5Mbit/s.These features make the TJA1043 the ideal choice for high speed CAN networkscontaining nodes that need to be available all times, even when the internal VIO and VCCsupplies are switched off.
