TJA1042T/3/1J Overview

For security on TJA1042, TJA1044, TJA1049, go to Secure CAN TJA1152.The TJA1042 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 the differential transmit and receive capability to (a microcontroller with) a CANprotocol controller.The TJA1042 belongs to the third generation of high-speed CAN transceivers from NXPSemiconductors, offering significant improvements over first- and second-generationdevices such as the TJA1040. It offers improved ElectroMagnetic Compatibility (EMC)and ElectroStatic Discharge (ESD) performance, and also features:Ideal passive behavior to the CAN bus when the supply voltage is offA very low-current Standby mode with bus wake-up capabilityTJA1042T/3 and TJA1042TK/3 can be interfaced directly to microcontrollers withsupply voltages from 3 V to 5 VThe TJA1042 implements the CAN physical layer as defined in the current ISO11898 standard(ISO11898-2:2003, ISO11898-5:2007) and the pending updated version of ISO 11898-2:2016.Pending the release of the updated version of ISO11898-2:2016 including CAN FD and SAEJ2284-4/5, additional timing parameters defining loop delay symmetry are specified. Thisimplementation enables reliable communication in the CAN FD fast phase at data rates upto 5 Mbit/s.These features make the TJA1042 an excellent choice for all types of HS-CAN networks,in nodes that require a low-power mode with wake-up capability via the CAN bus.

Features
