VeLIO Certified, High-Speed CAN Transceivers with Standby Mode

For security on TJA1042, TJA1044, TJA1049, go to

Secure CAN TJA1152, for higher data rates on these devices, go to

CAN SIC TJA1462.

The TJA1049 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, supplying the differential transmit and receive

capability to (a microcontroller with) a CAN protocol controller.

The TJA1049 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 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 off

* A very low-current Standby mode with bus wake-up capability

*

TJA1049T/3 and TJA1049TK/3 can be interfaced directly to microcontrollers

with supply voltages from 3 V to 5 V

The TJA1049 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 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 TJA1049 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.
