High-speed CAN transceiver
Rev. 3 — 24 April 2013
Product data sheet
1. General description
The TJA1043 is a high-speed CAN transceiver that 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 (up to 1 Mbit/s) 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
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.
