描述 Description

The TJA1049 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,supplying the differential transmit and receive capability to (a microcontroller with) a CANprotocol controller.
The TJA1049 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 off
A very low-current Standby mode with bus wake-up capability
TJA1049T/3 and TJA1049TK/3 can be interfaced directly to microcontrollers withsupply voltages from 3 V to 5 V

The TJA1049 implements the CAN physical layer asdefined in the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007 and thepending updated version of ISO 11898-2:2016). Pending the release of ISO11898-2:2016including CAN FD and SAE J2284-4/5, additional timing parameters defining loop delaysymmetry are specified. This implementation enables reliable communication in the CAN FDfast 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.
