TJA1049  
High-speed CAN transceiver with Standby mode  
Rev. 6 — 15 January 2018  
Product data sheet  
1. General description  
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 ISO 11898-2:2016 and  
SAE J2284-1 to SAE J2284-5. 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.  
2. Features and benefits  
2.1 General  
ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant  
Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase  
Suitable for 12 V and 24 V systems  
Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)  
VIO input on TJA1049T/3 and TJA1049TK/3 allows for direct interfacing with 3 V to 5 V  
microcontrollers  
SPLIT voltage output on TJA1049T and TJA1049TK for stabilizing recessive bus level  
Both variants available in SO8 and HVSON8 packages  
Leadless HVSON8 package (3.0 mm 3.0 mm) with improved Automated Optical  
Inspection (AOI) capability  
AEC-Q100 qualified  
Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)  
compliant)
