TJA1043T/1J Description

Short technical summary and product information.

The TJA1043T/1J from NXP Semiconductors is a third-generation high-speed CAN transceiver. It provides a physical interface between a CAN protocol controller and a two-wire CAN bus, suitable for automotive applications.

 

This transceiver supports data rates up to 5 Mbit/s in the CAN FD fast phase, compliant with ISO 11898-2:2016 and SAE J2284 standards. It features low-power management with local and remote wake-up capabilities, and passive behavior when the supply voltage is off. Advanced protection and diagnostic functions are included, such as bus line short-circuit detection.

 

The TJA1043T/1J can be interfaced directly with microcontrollers operating from 3V to 5V. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, making it ideal for high-speed CAN networks. The device is AEC-Q100 qualified and RoHS3 compliant.

 

Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount configuration, this transceiver is designed for reliable communication in demanding automotive environments.
